12/01/02

Hoshizaki recommends that the ice machine drain and

bin drain be piped separately to the drain connection point

allowing 1/4" per foot fall.

CONDENSATE DRAIN -

The condensate drain is generally connected to the ice

machine drain for simplicity. It can be piped separately to

the drain exit if desired.

A 6" vent tee is recommended as per drawing:

FLOW RATES -

The minimum flow rate requirements for Hoshizaki ice

maker units are as follows:

KM-150/250/280/AII Flakers 1.05 GPM

KM-500 1.58 GPM

KM-630/900/AII DCM's 2.11 GPM

KM-1300/1600 3.96 GPM

KM-2000/2400 4.23 GPM

Use this information when sizing a filter system for the ice

machine application.

NOTE: A good rule of thumb is to utilize a 3 GPM flow rate

filter for KM-150 through 900 and a 5 GPM flow rate filter

for KM-1300 or larger.

Transformer Application

All 208-230V models include a 115V transformer with a

208/230V selector switch. Be sure to select the position

that best matches the incoming voltage prior to supplying

power to the unit. (Voltage from the center tap to case

ground will be 67.5V due to the transformer circuit.)

208/230V models include 115V controls. They require a

115 / 208-230V circuit which has 4 wires including L1, L2,

dedicated neutral, and ground.

If a dedicated neutral is not available or the previous unit

used a 3 wire circuit, (L1,L2, & gnd.) a step-down trans-

former can be used at the unit to provide power to the

115V components. This will save on installation time and

cost if a dedicated neutral is not present.

Transformer # 4A0817-01 or equivalent can be used for

KM models. Transformer # 446240-01 or equivalent can

be used for F-1000 models. The transformer should be

mounted inside the compressor compartment and wired

using the following generic diagram.

LINE SET INSTALLATION

A universal line set adapter kit, part number OS-QUICK, is

available if you need to field engineer your line set. Both

lines should be insulated separately the entire length of run.

The refrigerant charge for a new unit is distributed between

the unit head and the URC condenser. The line set has a

minimal holding charge of 15 to 30 psig refrigerant vapor.

If you need to field engineer your line set or shorten/

lengthen a precharged line set you can do so by following

these steps:

1. Using the OS-QUICK kit, braze the line set connec-

tions. (If you shorten or lengthen a precharged line

set, recover the holding charge, cut or lengthen and

braze the connections.)

2. Pressurize the lines and leak check all braze joints.

3. Evacuate the lines through the service ports on the

Aeroquip quick connect fittings.

4. Charge both lines with 15 to 30 psig R-404A vapor.

To make Aeroquip connection to the unit head and

condenser:

1. Lubricate the threads and O-ring with clean

refrigerant oil.

2. Tighten the female connector until it bottoms out.

Note: Always use a back up wrench when tightening

these fittings.

3. Then turn an additional 1/4 turn to assure a good

brass to brass seal. Leak check the joints with soap

bubbles or an electronic leak detector.

12/20/03

2/20/03

12/01/02

SYSTEM CHARGE - R-404A

The ice machine head and URC condenser are shipped

with enough refrigerant charge for up to 66 feet of line set

length. The maximum line set length is 100 equivalent feet

from the head to the condenser.

For applications longer than 66 ft. up to the maximum 100 ft.

Length, additional refrigerant must be added. For units uti-

lizing 1/4" L.L. and 3/8" D.L., the line size should be in-

creased to 3/8"L.L. and 1/2"D.L. for the entire length of the

run. Add 16.5 ounces plus 0.4 oz. per foot over 66 feet. For

units utilizing 3/8"L.L., add 0,4 oz. per foot over 66 feet.

NOTE:

(1) Recommended line sizes are same as listed in

the line set application chart.

(2) Older models utilize R-502 refrigerant or R-22

refrigerant. Always check the unit nameplate for

the correct refrigerant type.

Do not connect components using different type

refrigerants!

(3) If refrigerant is added due to extended line set

length, mark the correct total charge on the unit

nameplate for future reference.

(4) When routing and installing remote lines, always

use standard refrigerant piping practices.

(5) Hoshizaki recommends eliminating any excess

loops in a pre-charged line set application before

making the unit connections. This will eliminate oil

traps and possible crimps in the excess tubing.

(6) A service loop should be included behind the unit

as shown in the illustration on page 13 to allow

the unit to be moved away from the wall if

needed.

CRITICAL CHARGE AMOUNT

The total system charge is critical for proper operation

according to Hoshizaki specification. Always weigh in the

proper charge per the following charge chart. (Remote

units show standard charge good for up to 66 feet.) Unit

charge information is also found on the unit Name Plate.

REFRIGERANT OIL

All R-404A models use Polyol Ester (POE-EAL) oil. POE oil

absorbs moisture easily. Extra care must be taken to re-

duce the possibility of moisture entering the system during

service. If moisture contamination is suspected, the oil

should be changed and the liquid line drier must be re-

placed. Changing the oil requires removal of the compres-

sor so that the oil can be drained and replaced with the

correct amount. See compressor data chart for oil amount.

Replacement compressors are shipped with POE oil.

“E” Control Board Functions

An instruction label explaining the “E” board features is in-

cluded somewhere on the unit. You should find it either on

the control box cover, on the inside of the front panel, or

under the top panel. A stick on label is also included with the

service replacement board. If you are replacing an “E” board,

be sure to place the new label over the original label. This

will advise anyone performing future service that the origi-

nal board has been replaced and explain the application

switch as outlined below.

The #2A1410-02 universal replacement board has an appli-

cation switch between relays X3 & X4 that is not included on

the original factory board supplied with the unit. This applica-

tion switch allows this replacement board to be used on older

C and Alpine control board models. The application switch

has 2 positions (C & ALP). On R-404A models, this switch

must be in the ALP position. If the switch is left in the C

position, the compressor contactor will energize as soon as

power is supplied to the unit whether the power switch is ON

or OFF.

There are 4 green LED’s which light in sequence throughout

the unit operation. It is important to note that the green LED’s

are not numbered consecutively. LED1 is located at the edge

of the board beside the K-2 transformer connection. The num-

bering sequence from the outside edge of the board is 1, 4, 3,

and 2.

The green LED’s are also used for a built-in output test which

can be conducted to diagnose a bad board. The label ex-

plains the output test procedure. The correct lighting sequence

for the output test is as follows. When the control switch is

switched ON with the output test switch S-3 ON, after a 5

second delay, LED2 lights. 5 seconds later LED2 goes out

and LED3 lights. 5 seconds later LED3 goes out and LED4

lights. 5 seconds later LED4 goes out and LED1 lights. 5

seconds later LED1 goes out and LED4 lights to begin the

normal sequence of operation. If the LED’s follow this se-

quence, the board is OK. If any other lighting sequence oc-

curs, the board is bad.

A copy of the “E” board label is included on the next page.

Review the board label thoroughly to understand the “E” board

functions.

ATTENTION !

THIS UNIT HAS A CONTROL PRODUCTS IMPROVED “E” CONTROL

BOARD INSTALLED. HOSHIZAKI PART NUMBER 2A1410-01.

The improved “E” board includes LED lights and audible alarm safeties. The

red LED indicates proper control voltage and will remain on unless a control

voltage problem occurs. At startup a 5 second delay occurs while the board

conducts an internal timer check. A short beep occurs when the power

switch is turned “ON” or “OFF”.

The green LED’s 1~4 represent the corresponding relays and energize and

sequence 5 seconds from initial startup as follows:

Sequence Step LED’s on: Length:Min. Max. Avg.

1 Minute Fill Cycle LED 4 60 sec.

Harvest Cycle LED 1, 4, & 2 2 min. 20 min. 3-5 min.

Freeze Cycle LED 1 5 min. 60 min. 30-35 min.

Reverse Pump Out LED 1, 3, & 2 10 sec. 20 sec. Factory set.

{With light on, LED 1 = Comp/RFM; LED 2 = HGV; LED 3 = PM; LED 4 = WV}

Note: LED’s are not numbered consecutively. They are # 1,4,3,2 from board edge.

The built in safeties shut down the unit and have alarms as follows:

1 beep every 3 sec. = High Evaporator Temperature >127° F.

Check for defrost problem (stuck HGV or relay), hot water entering

unit, stuck headmaster, or shorted thermistor.

2 beeps every 3 sec. = Defrost Back Up Timer. Defrost >20 minutes.

Orange LED marked “H Timer” energizes. Check for open

thermistor, HGV not opening, TXV leaking by, low charge, or

inefficient compressor.

3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > Specified Setting

Yellow LED marked “F Timer” energizes. Check for F/S stuck

closed (up), WV leaking by, HGV leaking by, PM not pumping, TXV

not feeding properly, low charge, or inefficient comp. Dip switches 9

& 10 allow for factory adjustment of this back up timer feature.

Note: 2 & 3 beep alarms represent 2 consecutive occurrences.

Additional alarms for mechanical bin switch:

4 beeps every 3 sec. = Short Circuit between the K4 connection on the

control board and the bin control. Check connections and replace

wire harness if necessary.

5 beeps every 3 sec. = Open Circuit between the K4 connection on the

control board and the bin control. Check connections and replace

wire harness if necessary.

Note: Units with mechanical bin switch installed, dip switch No.7 must be

in the “ON” position. If thermostatic control is used No. 7 must be “OFF”.

To manually reset the above safeties, depress white alarm reset button

with the power supply “ON”.

6 beeps every 3 sec. = Low Voltage. Control voltage < 92 Vac ±5%.

The red LED will de-energize if voltage protection operates.

7 beeps every 3 sec. = High Voltage. Control voltage > 147 Vac ±5%.

The red LED will de-energize if voltage protection operates.

Note: The voltage safety automatically resets when voltage is corrected.

The Output Test switch “S3” provides a relay sequence test. With power

OFF, place S3 on and switch power to ICE. The correct lighting sequence

should be none, 2, 3, 4, 1, & 4, in 5 second intervals, then normal sequence.

Components will cycle during test. S3 should remain in the “OFF” position for

normal operation.

The dip switches should be adjusted per the adjustment chart published in the

Tech Specs book. No. 8 must remain in the “OFF” position.

MANUAL RESET SAFETIES:

The Alpine control board has one manual reset safety. It is

the 127°F high evaporator temperature safety. There is no

indication that the Alpine board is off on this safety. You

will only notice that the unit will restart in the 1 minute fill

cycle when the power switch is shut OFF and Back ON.

This is the only way to reset this safety. If this occurs

check for a hot gas circuit or valve problem, a headmaster

stuck in bypass, hot water entering the unit, or a shorted

thermistor. In case of a shorted thermistor, the unit will not

restart. You will hear a relay click after approximately 2

seconds and the unit will remain off.

The “E” control board can have up to 5 manual reset safe-

ties. They are outlined in the control board function label.

These safeties shut the unit down and assist the service

technician in diagnosing the problem.

The safeties include audible and visual alarms as follows:

1 Beep = 127ºF (52.8ºC) high evaporator temp. safety.

2 Beeps & orange LED = 2 consecutive 20 minute harvest

cycles.

3 Beeps & yellow LED = 2 consecutive maximum freeze

cycles.

4 Beeps = Short circuit on mechanical bin control circuit.

5 Beeps = Open circuit on mechanical bin control circuit.

To reset either safety, press the white reset button

on the control board with the power ON. Next, pro-

ceed to check the items outlined on the function label.

The items listed on the function label represent the most

common reasons that the safety would function. There

may be other remote possibilities however, the items listed

should be checked first.

VOLTAGE PROTECTION:

Built-in voltage protection for the “E” board will automati-

cally shut the unit down and beep if either a high or low

voltage problem occurs as follows:

6 Beeps = Low voltage condition.

7 Beeps = High voltage condition.

The high and low voltage protections are the only board

alarms that will automatically restart the unit when the volt-

age returns to normal. If constant voltage fluctuation oc-

curs, additional external voltage protection will be required.

PENN VALVE

HEAD PRESSURE CONTROLS

WATER-COOLED

An adjustable (Pressure Modulated) water-regulating valve

is installed on the water-cooled condenser outlet. A # V46

Johnson Controls Penn valve is used. A label on the valve

housing identifies the Penn valve.

Adjust:

CW - for lower pressure and outlet water temperature with

higher water flow.

CCW – for higher pressure and outlet water pressure

with lower water flow.

CONDENSER OUTLET WATER TEMPERATURE RANGE.

Model Range High side pressure

All KM 104 ~ 115 ºF 270 psig.

All DCM 100 ~ 104 ºF 260 psig.

All F 100 ~ 104 ºF 260 psig.

In some cases, if the water-cooled unit has been in opera-

tion for a long period of time, adjusting the water- regulating

valve does not allow proper pressures. In this case the wa-

ter-cooled condenser is likely scaled and requires cleaning.

An acid based condenser cleaner should be circulated through

the coil using an acid pump, until the inner tube is free of

scale. Once the scale is removed, the water-regulating valve

should be adjusted to maintain the range and pressure listed

above.

REMOTE HEAD PRESSURE CONTROL

All remote condenser units utilize a condensing pressure regu-

lating (CPR/Headmaster) valve to maintain head pressure in

low ambient conditions. You will find a Sporland LAC-4 210

psig. valve mounted in the condenser of all R-404A remote

units with the exception of the KM-2400SRF3. The KM-

2400SRF3 model uses a Sporland LAC-5 210 psig valve

which is mounted in the unit head.

The symptoms of a bad headmaster are similar to an under-

charged unit. To diagnose a bad headmaster, add additional

refrigerant in 2 lb. increments and watch the pressures. If

the pressures begin to look normal, the unit was undercharged.

In this case, leak check the system to find the leak and use

normal refrigeration practices to recover, repair, evacuate and

recharge the unit. If not, a bad headmaster is a possibility.

Check to see if the valve is stuck open by conducting tem-

perature checks at the outlet of the headmaster. Replace the

headmaster as necessary. Use safe refrigeration practices

when removing the valve and protect the valve from over-

heating.

HIGH PRESSURE SAFETY SWITCH

An automatic reset high pressure safety switch is utilized on

all Hoshizaki “F” series ice makers. The pressure switch part

numbers and settings are as follows:

BIN CONTROL

KM BIN CONTROLS:

KM/KML cubers will use one of three types of bin controls.

The type of bin control will vary depending on the unit style,

or model and serial number.

1. THERMOSTATIC BIN CONTROL:

The thermostatic bin control is the primary control that sup-

plies 115 volts to all major components in the unit except the

compressor. When this control is closed, 115V is supplied

to the control transformer and to the K1 control board

connector which switches 115 volts to the components as

the sequence dictates. A thermostatic capillary bulb is

mounted in the ice drop zone area or on a drop down

bracket which extends into the bin cavity.

The Thermostatic control is normally closed. (It opens on

temperature drop and closes on temperature rise.) When

ice touches the thermostatic bulb, the bulb pressure opens

the bin control switch to shut the unit down. The thermo-

static bin control will shut the unit down at any point in the

sequence of operation if ice contacts the control bulb. The

shut down time will depend on the control adjustment. This

adjustment is factory set however it should always be

checked at start-up to assure proper operation.

High

altitude areas require adjustment.

When ice is moved

away from the bulb, the unit will always restart in the 1-

minute fill cycle.

Note: The unit will not operate in either ICE or WASH un-

less the thermostatic bin control switch is closed.

Larger M models and S models include a drop down bulb

bracket. This bracket should be secured to the unit base

and the control plug connection must be made before

the unit will operate. A bin control extension bracket is

included with all S models. Be sure to install the extension

12/20/03

2/20/03

12/01/02

When replacing a thermostatic bin control, check the op-

eration by holding ice against the thermostatic bulb with the

control switch in the wash position. The pump should stop

within 6 to 10 seconds. Adjustment up to 30~45 seconds

could be acceptable depending on the application. Adjust

the control “CCW” for a faster shut down.

Note: Control board dip switch number 7 must be OFF for

this control to operate the unit. A thermostatic bin control

may be used on KML models and is required for some

dispenser application.

2.MECHANICAL BIN CONTROL:

KML and some M models use a mechanical bin control.

This control includes a proximity switch and actuator paddle

assembly. The mechanical bin control assembly mounts in

the ice drop zone area and will shut the unit dowm within 3

seconds when ice pushes the actuator paddle to the full

right position, away from the proximity switch. Shut down

will only occur during the first 5 minutes of the freeze cycle

when the paddle is moved away from the proximity switch.

If the paddle is moved away from the proximity switch and

held at any other time during the sequence, the unit will

continue to run until the next freeze cycle occurs. This

feature allows for a full batch of ice every cycle so that

there are no small cubes in the bin.

A resistor wireing harness connects the mechanical bin

control to the red K4 connector on the control board. As the

proximity switch opens and closes, the resistance value

will change to either start up or shut down the unit.

bracket. When installing, make sure the bracket points

downward so that the cubes will easily fall away from the

bin control bulb.

b) When the unit is held to the right, the resistance at the

K4 red connector will be 15.8 K ohms and the unit will shut

down within 3 seconds during the first 5 minutes of the

freeze cycle or at the beginning of the next freeze cycle at

any other time in the sequence of operation.

Mechanical control in the normal position supplies 7.9 K

ohms at red K4 connector to start unit.

Mechanical bin control in the full right position supplies

15.8 K ohms at connector red K4 to shut unit down.

Note: Control board dip switch number 7 must be ON for

this control to operate the unit.

3. CAPACATIVE PROXIMITY SWITCH: KM-1300NRF

This control is used only on the KM-1300NRF model which

was designed tor 42 inch beverage dispenser applica-

tions. You will find it only on this specific model. The control

works by sencing mass (in this case, ice) within 1/2 to 1

F/DCM Bin Control

Flaker / DCM units use a mechanical bin control. A paddle

pivots on a hinge pin to operate either a micro- switch or

magnetic proximity switch. For proper operation, make sure

that the paddle swings freely. The F-450MAF-C cubelet

unit uses an Infrared eye control since it is designed for

dispenser applications. This control has a seperate DC

power supply and an infrared sensor which is mounted

to the base of the ice chute.

CAPACITORS

See wiring diagram reference chart for capacitor ratings.

Check capacitors with an ohm meter for a short or open

circuit. A capacitor checker can be used to check the

capacitance however, it is a good common practice to

change a run capacator any time a PSC motor is replaced.

Always check the run capacitor if a PSC motor will not

start, is running slow, overamping, or overheating.

inch of the sensor. It also connects to the K4 red connec-

tor on the control board and has the same operating se-

quence as the mechanicam bin control.

The capacitive proximity control has 4 components includ-

ing a sensor, bin control relay, 24VDC power supply and

resistor harness. This resistor harness is slightly different

from the harness used for the mechanical control. It will

supply either 15.8 K ohms or 5.6 K ohms to the red K4

connector to control the unit.

As the sensor switches, the resistance value will change

to either start up or shut down the unit through the control

board K4 connector.

a) When no ice is present within 1/2~1 inch of the sensor

end, the resistance at the K4 connector will be 5.6 K ohms

and the unit will start. This is the bin empty signal.

b) When ice is present within 1/2~1 inch of the sensor, the

resistance at the K4 connector will be 15.8 K ohms and the

unit will shut down within the first 5 minutes of the freeze

cycle. This is the bin full signal.

Note: Control board dip switch number 7 must be ON for

this control to operate the unit.

HOSHIZAKI KM CUBER

SEQUENCE OF OPERATION

THE STEPS IN THE SEQUENCE ARE AS FOLLOWS:

NOTE: When power is supplied to the “E” Control board,

a 5 second delay occurs at start-up.

1. 1 Minute Fill Cycle

The unit always starts in the 1 minute fill cycle. When

power is applied to the unit the water valve is ener-

gized and the fill period begins. After 1 minute the

board checks for a closed float switch. If the float

switch is closed the harvest cycle begins. If not, the

unit will not start without adequate water in the sump.

This serves as a low water safety shut off. The water

valve will remain energized through additional 1 min-

ute cycles until water enters the sump and the float

switch closes.

2. 1st Harvest Cycle

The compressor starts, hot gas valve opens, water

valve remains open and harvest begins. As the evap-

orator warms, the thermistor located on the suction

line checks for a 48° F. temperature. When 48° F. i s

reached, the harvest is turned over to the adjustable

control board defrost timer which is factory set for

normal conditions. This adjustment can vary the de-

frost timer from 1 to 3 minutes.

3. Freeze Cycle

After the timer terminates the harvest cycle, the hot

gas and water valves close, and the ice production

cycle starts. For the first 5 minutes the controller

board will not accept a signal from the float switch.

This 5 minute minimum freeze acts as a short cycle

protection. At the end of 5 minutes the float switch

assumes control. As ice builds on the evaporator the

water level in the sump lowers. Thefreeze continues

until the float switch opens and terminates ice

production.

12/20/03

2/20/03

12/01/02

4. Harvest Pump Out

When the float switch opens and signals the completion

of the freeze cycle, the harvest cycle begins. The hot

gas valve opens and the compressor continues to run.

The drain timer starts counting the 10/20 second pump

out.

The water pump stops for 2 seconds and reverses,

taking water from the bottom of the sump and forcing

pressure against the check valve seat allowing water

to go through the check valve and down the drain. At

the same time water flows through the small tube to

power flush the float switch. When the drain timer

stops counting, the pump out is complete.

Pump out always occurs on the 2nd harvest after

startup. The Alpine control board allows for adjustment

for pump out to occur every cycle, or every 2nd, 5th or

10th cycle from this point.

5. Normal Harvest Cycle

The water valve opens to allow water to assist the

harvest. As the evaporator warms, the thermistor

reaches 48° F. The control board receives the

thermistor signal and starts the defrost timer. The

watervalve is open during harvest (defrost) for a

maximum of 6 minutes or the length of harvest,

whichever is shorter. When the defrost timer completes

its count down, the defrost cycle is complete and the

next freeze cycle starts.

The unit continues to cycle through 3 , 4 and 5

sequence until the bin control senses ice and shuts

the unit down.

KM CHECK OUT PROCEDURE

The following is a detailed explanation of the KM 10

Minute Check Out procedure.

The 10 minute check out procedure is basically a

sequence check which can be used at unit start-up or

for system diagnosis. Using this check out procedure

will allow you to diagnose electrical system and

component failures in approximately 10 minutes under

normal operating conditions of 70°F or warmer air and

50°F or warmer water temperatures. Before conducting

a 10 minute checkout, check for correct installation,

proper voltage per unit nameplate and adequate water

supply. As you go through the procedure, check to

assure the components energize and de-energize

correctly. If not, those components and controls are

suspect.

10 MINUTE CHECK OUT PROCEDURE

1. Turn power OFF - gain access to unit control box.

2. Turn power ON – place control switch in ice position.

Note: A 5 second delay occurs for units with “E” control

board.

A) 1 Minute Fill Cycle begins – WV energized.

After 1 minute, control board checks FS. If FS is

closed…unit cycles to Harvest. Continue to (B).

If FS is open, unit repeats 1 minute fill cycle until

water enters and FS closes (low water safety

protection during initial start up and at the end of

each harvest)

Diagnosis: If WV does not open, check for no supply

voltage at WV terminals, bad coil, or plugged screen

or external filter (no water flow). If unit fails to start

harvest, check for open FS or bad 1 minute timer in

board.

B) Initial Harvest Cycle – WV remains energized,

CC energizes to start C, HGV, & (FM on RS

model) energize. Evaporator warms…thermistor

senses 48°F…turns operation of harvest to

control board defrost completion timer. Timer

completes counting (1 ~3 minutes)…Unit cycles

to freeze.

Diagnosis: Check if C is running, HGV is open, WV

still open. Avg. harvest cycle at factory setting is 2

~ 3 minutes. How long does initial harvest last? 1.5

minutes after initial harvest begins, touch C

discharge line. Is it hot? If not check refrigerant

pressures and C operation. If it is hot, touch inlet

line to the evaporator. Is it hot? If it is hot and unit is

12/20/03

not starting freeze cycle, check defrost

completion timer adjustment, thermistor for open

circuit, discharge line temperature, C efficiency,

and if HGV is fully open.

C) Freeze cycle – C remains energized, PM, (LV

on RS model), and FM energize…WV & HGV

de-energize. Unit is held in freeze by 5 minute

short cycle protection timer. After 5 minutes

freeze cycle operation to transferred to FS for

freeze termination. During first 5 minutes of

freeze, confirm that evaporator temperature

drops. After 7 minutes in freeze, remove black

FS lead from K5 connector…Unit should

immediately switch to pump out cycle.

Diagnosis: If evaporator is not cold, check for HGV

still open, TXV not opening properly, WV

continuing to fill reservoir, improper unit pres

sures, and inoperative C. If unit remains in freeze

with FS removed replace board. * Normal freeze

cycle will last 20 ~ 40 minutes depending on

model and conditions. Cycle times and

pressures should follow performance data

provided in Tech –Specs.

D) Pump Out Cycle – (10/20 second pump out)

C remains energized, HGV energizes, FM de-

energizes, PM stops for 2 seconds and starts in

reverse rotation for 10/20 seconds.( This

removes contaminants from the water reservoir

through check valve and down the drain and

allows for power flush of FS.) Check clear

tubing at check valve housing or unit drain for

water flow.

Diagnosis: If PM does not reverse, check PM circuit

and capacitor. If water does not pump out,

remove housing and check/clean valve

assembly.

E) Normal Harvest Cycle –same as Initial Harvest

Cycle – Return to B)…* Unit continues to cycle

through B)…C)…& D) (Setting can be adjusted

to skip D until every 2, 5, of 10 cycles)…until bin

control is satisfied or power is switched OFF.

RESERVOIR FLUSH SYSTEM

A displacement device ( cap or assembly ) is positioned

over the top of the overflow stand pipe. This device al-

lows sediment to be pulled from the bottom of the reservoir

and flush down the drain when overflow occurs. Water

should always overflow the stand pipe for a short period

towards the end of harvest to allow this flushing action. To

extend this flushing action, adjust dip switches 1 & 2 for

longer harvest. If overflow does not occur, you likely have

restricted water flow into the unit. Check the inlet water

valve screen, incoming water line size, or the external filter

system. The displacement device must be in position for

proper operation. If not, water goes down the drain during

freeze and short cycling occurs.

PUMP-OUT CHECK VALVE

A mechanical spring & seat check valve is located in

the pump-out housing. If this check valve sticks open,

water flows down the drain during freeze and a 5 minute

freeze cycle occurs. In this case, check for a displaced

seat, trash or a weak spring. Replace the spring if it is

weak. When reinstalling the check valve, the seat always

faces the pump supply.

KML PUMP OUT

The Standard KM series has a dual winding pump motor

that reverses direction during the pump-out cycle. The

reverse rotation pumps sediment down the drain. The KML

models have a single winding pump motor that does not

reverse. Instead of a pump-out check valve and reversing

pump, a drain solenoid and the pump motor are energized

by a relay so that sediment is pumped out.

KM CONTROL SWITCH

The standard KM models have a three position control

switch. The switch positions are “ICE-OFF-WASH”. Also, a

manual cleaning valve includes a micro-switch which opens

the control transformer circuit to the control board during

the cleaning process. This cleaning valve must be in the

horizontal position to make ice.

The KML models have 2 switches. The control switch po-

sitions are “ICE- OFF-SERVICE”. With the control switch in

the SERVICE position, the SERVICE switch is energized.

CONTROL BOARD FUSE

Beginning in May 2002 Hoshizaki began including a 10 Amp

control fuse on KM models. This new feature was added

to specific models as they were produced. The fuse is

located in a fuse holder that is mounted on the control box

and connected in the circuit supplying 115V to the control

board 10-pin connector through pins 10 & 7.

The purpose of this fuse is to protect the control board

from damage in case of a short circuit in one of the compo-

nents. This fuse will also offer some protection against

external wiring problems, voltage spikes, and surges.

If the fuse is blown, you should isolate each individual

component and check for shorts and grounded conditions.

It is important that any external wiring connections, includ-

ing the remote condenser circuit be checked before re-

placing this fuse. If the problem is not corrected, the fuse

will blow again.

In general, you should check the component that connects

to the pin that has a burnt trace on the back side of the

board first. The fuse is a Bussman AGC 10 Amp 250VAC

slow blow fuse, Hoshizaki part # 4A0893-07 and should

only be replaced with one of identical size and type. A

replacement fuse is taped to the control box.

Should you want to add this feature to an existing KM unit

in the field, you can order fuse holder # 4A0892-01, fuse

label # 4A2817-01 and fuse # 4A0893-07, through your

local distributor. You should also make a note on the wiring

diagram indicating the fuse addition, fuse size and type.

On the following page, you will find a typical wiring dia-

gram showing where the fuse is wired in the circuit and

the label that is included on the control box.

The service switch also has three positions, “DRAIN-

CIRCULATE-WASH”. With the control switch in SERVICE

and the service switch in DRAIN, the pump starts and drain

valve solenoid opens to automatically drain the reservoir.

In the CIRCULATE position, the pump motor circulates cleaner

to the outside of the evaporator. In WASH, the cleaning

solenoid energizes and the pump circulates cleaner to the

inside and outside of the evaporator.

COMPONENT CHECKS:

1.FLOAT SWITCH:

Check out the float switch with an ohm meter. When the

float is up, the switch is closed. When the float is down,

the switch is open.

STICKING FLOAT SWITCH:

It is important to remember that the float switch is in the

water circuit and is susceptible to scale buildup. This can

cause the float to stick either up or down. If the float

switch is sticking, it should be cleaned thoroughly with ice

machine cleaner and checked for proper operation. If the

float switch is defective, it should be replaced however, a

dirty float switch is not considered a warranty item.

The symptoms of a sticking float are:

UP/CLOSED: 60 minute freeze cycle, larger cubes,

and pump cavitates prior to harvest.

After 2 consecutive maximum freeze cycles, the

unit will shut down on a 3 beep safety.

To reset this alarm, press the Alarm Reset but

ton on the board with power ON.

DOWN/OPEN: Unit shuts down on low water

safety and water runs continuously.

Heavy scale can be difficult to remove from the float. The

float is available as a replacement part as well as the float

pin. If the housing is defective, replace the complete float

switch assembly.

2. THERMISTOR: Check out the thermistor mounting and

check resistance versus temperature per this chart:

THERMISTOR TEMPERATURE / RESISTANCE

SENSOR TEMP (F°) RESISTANCE (K OHMS)

0 14.4

10 10.6

32 6.0

50 3.9

70 2.5

90 1.6

The symptoms of a bad thermistor are:

OPEN: 20 minute harvest cycle. The unit will shut

down on a 2 beep safety after 2 consecutive 20

minute harvest cycles.

SHORTED: Unit locks out on manual reset high temp-

erature 1 beep safety in this case.

High Temperature Safety: If evaporator reaches 127°F

the thermistor signal (500 ohms) shuts down the unit on

this manual reset. A 1 beep alarm will occur.

To reset this

alarm, press the Alarm Reset button on the board

with power ON.

Then check the items listed on the control

board label for a 1 beep alarm.

UNIVERSAL REPLACEMENT FLOAT SWITCH:

There are two styles of KM float switches. One has no

hole in the outside pipe and one has a hole in the outside

pipe. Float switch number 4A0886-02 can be used as a

universal replacement on any KM unit. Simply seal off the

small hole in the outside tube with silicone or a seal cap

from 3/8” refrigeration tubing if it is not needed.

CONNECTOR BOOT:

The float switch boot will sometimes collect scale deposits

since it is in a low area of the water circuit. The boot should

be cleaned thoroughly during scheduled maintenance. Due

to age and high amounts of chlorine in the local water

supply, it can also deteriorate and may cup upward in the

middle holding the float up . In this case, the boot should be

replaced. Order part number 426799-01 as universal re-

placement part and cut the tube to length as needed.

12/20/03

2/20/03

12/01/02

Note: The Thermistor must be mounted using a heat

sink compound to assure good heat transfer and ac-

curate sensing. Use Hoshizaki Part Number 4AO683-

01 or equivalent. (Radio Shack #276-1372 or GE Elec-

tronics #10-8108, ect.)

3. CONTROL BOARD: The electronic control board

maintains the sequence of operation. There are 3

input connections to the board.

1. The Float switch connects to the control board

through the black K5 connector.

2. The thermistor connects to the control board

through the white K3 connector.

3. If a mechanical bin control is used, it will connect

to the K4 Red connector. ( In this case, dip switch

#7 must be set to the ON position.)

The control transformer supplies 10.5 VAC control

voltage to the K2 connection. The control board will

not operate unless control voltage is present at K2.

Proper control voltage is indicated by the Power

OK red LED ON.

The final connector on the control board is the K1

10-pin connector. This connector supplies 115 VAC

into the control board switchin components or

relay contacts and powers the individual com-

ponents during the sequence of operation.

The control board also has 10 dip switches that

allow for board adjustments. These switches are

set from the factory for proper operation and maxi-

mum efficiency. See control board adjustment chart

for factory settings and adjustments.

BOARD CHECKOUT: Before replacing a control

board that does not show a visable defect and

that you suspect is bad, always conduct the fol-

low checkout procedure. This procedure will help

you verify your diagnosis.

1. Check the dip switch settings to assure that

#3,4, 7, 8, 9, & 10 are in the factory setting. Out-

put test switch S3 should also be OFF. Switches

1, 2, 4, & 5 are cleaning adjustments and the set-

tings are flexible.

12/20/03

2/20/03

12/01/02

2. Turn the control switch to ICE and check for proper

control voltage. If the Red LED is ON, the control volt-

age is good. If the Red LED is OFF, check the control

transformer circuit. See checking control transformer.

3. Next, check the 115 volt input at the 10-pin connector.

Check the brown wire at pin #10 to a white neutral

wire for 115 volts. (Always choose a white neutral

wire to establish a good neutral connection when

checking voltages.) A jumper also feeds 115 volts

into pin # 7. If no voltage is present, check the 115

volt supply circuit.

4. Check the board sequence using the S3 output test.

a) Turn the control switch to OFF and switch S3 ON.

b) Turn the Control switch to ICE and watch the light-

ing sequence of the 4 green LED’s numbered 1, 4, 3,

2 from the board edge. The Red LED should light in

about 3 seconds.

About 3 seconds later, LED 2 should light.

5 seconds later, Led 2 will go out and LED 3 will light.

5 seconds later, Led 3 will go out and LED 4 will light.

5 seconds later, Led 4 will go out and LED 1 will light.

5 seconds later, Led 1 will go out and LED 4 will light.

This sequence completes the output test and the unit

is now in the 1 minute fill cycle.

Note: If the LED’s light in a different sequence or the 5-

second interval does not occur as explained, the control

board is bad and should be replaced. If the test sequence

is correct, turn the control switch OFF and switch S3 OFF.

The S3 switch must remain in the OFF position during nor-

mal operation. The components will cycle during this test.

5. You have checked the board sequence and now

need to check the output to each component through

the K1 10-pin connector for 115 volts. Follow the wir-

ing color code on the wiring diagram or use the generic

drawing in the wiring diagram section to check each

component for 115 volts through out the sequence and

check from each pin to a white wire.

Note: Checking from pin to case ground can give a false

reading in some instances. Always choose a white neu-

tral wire to establish a good neutral connection when

checking voltages.

4. BIN CONTROL:

Checkout for the bin control will vary depending on the

model and control that is used.

a) THERMOSTATIC BIN CONTROL: The thermostatic

bulb is mounted in the ice drop area to sense the ice

buildup. To adjust the bin control, hold ice against the

bulb while the unit is operating. You will find it easier to

place the control switch to the wash position to check

the bin control operation. It is easy to hear the pump

motor stop when the bin control opens. The unit should

shut down within a 10 second window when the

control is adjusted properly. If this does not occur,

adjust the thermostatic control by turning the screw-

driver slot. Adjusting towards warmer will allow the

unit to shut down quicker. This adjustment should be

checked at installation, when diagnosing a bin control

problem, or if a replacement bin control is installed.

KM 150 / 250 / 280 / 500 / 630 /900 units have a bin

control mounted in the ice drop zone area. KM-1300M /

S and larger units have a drop down bracket that must

be dropped down, secured, and plugged in at installa-

tion. The ice must contact the bulb to operate the

bin control. Some bin applications require an exten-

sion bracket or relocation of the bulb mounting to allow

for proper shut down. Check this positioning if the

control is adjusted properly and ice continues to back

up into the evaporator section. Assure that the exten-

sion bracket is installed.

The symptoms of a bad thermostatic control are:

STUCK CLOSED: The unit continues to operate when the

bin is full. This allows ice to back up in the evaporator

compartment and generally causes a freeze up condition.

This will also occur if the bin control is adjusted too cold or

fully “CW”. Check the adjustment and bulb location before

you diagnose a stuck bin control.

STUCK OPEN: The unit will not start in the ice position. An

easy method to check for an open bin control is to flip the

control switch to WASH. If the pump starts, the bin control

is closed.

b) MECHANICAL BIN CONTROL: The mechanical bin

control uses a moving actuator paddle to open and

12/20/03

2/20/03

12/01/02

closes a magnetic proximity switch. The control is con-

nected to the red K5 connector on the control board

through a resistor harness. As the proximity switch

opens or closes, the resistance will change to signal

the control board to start up or shut down. The control

board will only respond to this change in resistance

during the first 5 minutes of each freeze cycle.

Note: Dip switch # 7 must be in the ON position for

this control. When dip switch # 7 is ON, the following

2 safeties will occur if the mechanical control fails:

4 Beeps = Short circuit on K5 bin control circuit.

5 Beeps = Open circuit on K5 bin control circuit.

To reset either safety, press the white reset

button on the control board with the power ON.

CHECKOUT: To check this control with the unit running,

you must be in the first 5 minutes of the freeze cycle.

Turn the control switch to OFF and back to ICE. Allow

the unit to cycle through the 1 minute fill cycle and the

initial harvest cycle. Once the freeze cycle begins

(LED 1 ON and when you hear the pump motor start

you will know that the freeze cycle has begun), push

the control paddle to the full right position and the unit

should shut down within 3 seconds.

Another method to check this control is to unplug the

wiring harness from the K5 Red connector and check

the resistance at the end of the harness with an ohm-

meter as the proximity switch opens and closes.

1) When the control paddle is hanging in the normal

position, (Bin Empty) the resistance at the red K4

connector will be 7.9 K ohms.

2) When the control paddle is held to the full right

position, (Bin Full) the resistance at the red K4

connector will be 15.8 K ohms.

c) CAPACITIVE PROXMITY SWITCH: This control is

used on the KM-1300NRF model only. It operates with

the same sequence as the mechanical control and has

the same safeties. The difference is that this control

has a separate 24VDC power supply and operates

through a bin control relay.

12/20/03

2/20/03

12/01/02

CHECKOUT:

To check the operation of this control follow the same check

out procedure as with the mechanical control. Instead of

moving a paddle, you will place your hand within 1/2~1

inch of the sensor end. With the control switch in ICE, you

should hear the bin control relay switch when you move

your hand away from the sensor end and back again.

Check the resistance supplied at the Red K4 connector as

you move your hand back and forth at the sensor end.

Unplug the harness and use an ohmmeter to check the

resistance. As the sensor switches, the resistance value

will change as follows:

a) When your hand is away from the sensor end, the

resistance at the K4 connector will be 5.6 K ohms. This is

the bin empty signal.

b) When your hand is within 1/2~1 inch of the sensor, the

resistance at the K4 connector will be 15.5 K ohms. This is

the bin full signal.

If the relay does not switch or the resistance does not

change, check the control wiring, relay operation, and the

control power supply for 115 VAC input / 24 VAC output.

Note: Remember that dip switch # 7 must be ON and the

control will have these safeties.

4 Beeps = Short circuit on K5 bin control circuit.

5 Beeps = Open circuit on K5 bin control circuit.

F/DCM BIN CONTROL:

DCM bin controls may be a mechanical flapper with a mag-

netic proximity switch or a micro-switch assembly. Since

these controls have moving parts, make sure that all parts

move freely. Sticking can occur if scale builds up at the

pivot points. All flakers except the F-450MAF-C use the

mechanical/proximity switch control. If the bin control fails,

the spout will fill with ice causing higher gear motor current

and the gear motor protect fuse will blow.

The F-450MAF-C has an infrared eye bin control. A sepa-

rate power supply provides 24 VDC to the infrared eye.

This power supply is mounted in a separate control box

along with the bin control relay. The IR sensor is mounted

on the outside of the chute base in a molded indentation.

Two mounting holes mount the sensor to the chute base.

The sensor has two LED lamps that light to show that

power is supplied. Since the voltage is DC, the sensor is

polarity sensitive. The sensor has four wires. The orange

wire is capped off and not used. The black wire connects

to the coil of relay X7. The brown wire is the positive lead

and connects to terminal J2-1 on the power supply. The

blue wire is the negative lead and connects to terminal J2-

2. If these wires are crossed, the sensor will not shut the

unit down. The result will be that the spout will fill with ice

causing higher gear motor current and the gear motor pro-

tect fuse will blow. In this case, the bin control is the first

component to check.

The sensor has two adjustments that are factory set. The

first adjustment sets the operation mode of the sensor. It

must be in the D position. The second adjust the operating

distance of the infrared beam at approximately 4”. It should

be set so that the white dot on the dial is at 12 o’clock (top

dead center). These settings should not be altered.

5. KM CONTROL TRANSFORMER: The KM control trans-

former supplies 10.5 VAC to the control board through the

K2 connector. This 115V/10.5V stepdown transformer is a

heavy duty component with an internal thermal overload.

The primary winding of this transformer will handle higher

voltage without damage because the thermal overload will

open to protect the winding in the case of improper supply

voltage. The control board monitors the output voltage of

this control transformer and provides automatic reset high

and low voltage protection.

The red LED on the control board will not light if no control

voltage is supplied. The 115V transformer primary circuit is

supplied through the thermostatic bin control, control switch,

high pressure switch, and low pressure switch if included.

If either of these switches are open, there is not control

voltage at the K2 connector and the unit will not operate.

The transformer secondary circuit includes the cleaning

valve interlock switch. If this switch is open, no control

voltage is supplied to the K2 connector so the unit will not

operate. Always check the cleaning valve position and

interlock switch if the red LED is off.

Because of the voltage protection, if the control trans-

former fails, it is important to use the correct OEM part.

6. KM PUMP MOTOR ASSEMBLY:

The KM pump assembly has a dual winding PSC motor with

an internal overload. The motor has a cast housing and

sealed stainless steel roller bearings. No lubrication is

required for these roller bearings.

If the pump motor fails, always repalce the pump motor

capacitor. If other failures occur, the front end of the pump

assembly is rebuildable. The mechanical seal is the most

common failure part and can be replaced.

Following, are the assembly breakdown’s for two generic

pump assemblies. Use these drawings as a guide to reas-

semble a pump assembly that you are rebuilding.

7. INLET WATER VALVE: Hoshizaki uses inlet water valve

solenoid to fill the reservoir for ice making. This constant

duty solenoid valve is very reliable however, in areas of

hard water and high levels of chlorine, the diaphragm is

susceptible to failure.

Water quality is constantly changing and local municipali-

ties are now adding higher levels of chlorine, chloramine,

and chlorine dioxides to the water. These agents can dam-

age rubber parts and effect the diaphragm life.

The diaphragm is made of rubber and ABS and has a bleed

port on the inside ABS piece. This port allows the pressure

to balance on the top and bottom of the diaphragm so that

the valve will open and close properly with the spring

pressure. If the rubber becomes dry and brittle or the

bleed port is plugged with trash or debris, the valve will

leak by. In this case the valve can be disassembled for

cleaning and the diaphragm and inlet screen can be cleaned

or replaced. It is important to remember that the warranty

covers repair of defects and not cleaning. Should the valve

be scaled or dirty, it should be cleaned and bill to the cus-

tomer.

Below you will find an exploded view of the valve assem-

bly and instructions for reassembly of the valve. When

replacing the diaphragm and re-assembling the

valvereplacing the diaphragm, it is important that the plunger

is in the correct position. This plunger has a white plastic

seal on one end and is metal on the other end. The white

seal end of the plunger must be in contact with the dia-

phragm in order for the valve to work correctly.

Because of the different flow rates, it is important to use

the correct OEM water valve when servicing a Hoshizaki

ice maker. Use the following chart to identify the correct

valve, diaphragm or inlet screen.

Diagnosing water problems.

Many common water related problems will cause cubes to

look unnatural. Looking at the ice in the bin will point you

towards the problem area. Study these shapes and causes

to help you diagnose water related problems.

1. Normal cube, No problem.

Average cube size 1/2” thick x

1 1/8” wide x 1 1/2” high.

2. Larger than normal cube with heavy

saddled edges.

Note: Normal cube may have slight saddled edge.

If the float switch sticks in the up position, (closed ) the

unit will have a consistent 60 minute freeze cycle. This

will result in heavy saddled edges and may cause pump

cavitation and ice to stick on the evaporator or ice pos-

sible bridging.

A FREEZE UP MAY OCCUR IF ICE STICKS DUE TO

THE LARGER EDGES.

12/20/03

2/20/03

12/01/02

3. Bridging or ice strips

a) Bridging that occurs on all ribs of all evaporator plates

is the result of excessive water in the reservoir. This is

caused by the inlet water valve leaking by. Check for a

plugged bleed port in the water valve diaphragm or a

defective water valve.

b) May be the result of # 2.

c) Bridging can occur on a few ribs if some of the holes in

the water distribution tubes are plugged. An inspection

of the ice build up on the evaporator will show some ribs

with no ice and others with strips. Clean the water

distribution system.

d) Bridging on 1 or 2 plates of a multiple evaporator unit

can result from water distribution problems or a refrig-

eration system problem. Eliminate water problems first

then check TXV, hot gas valve, charge, etc....

BRIDGING WILL GENERALLY CAUSE A FREEZE UP.

12/20/03

2/20/03

12/01/02

4. Melt away of back of cube

a) This can occur if the evaporator plate is scaled up.

De-scaling is required.

b) Insufficient water flow during harvest can also cause

the flat side of the cube to melt away. Check for a

plugged inlet water valve screen, plugged external

filter, low water pressure, or a small water line size.

EITHER OR BOTH OF THESE ITEMS CAN CAUSE

THIS SYMPTOM.

5. Small cube

a) Can be caused by a low volume of water at the begin-

ning of freeze. Check for adequate water flow during

harvest. See item 4 b)

b) If the pump out check valve is stuck open or has a

weak spring, the water left in the reservoir will be

pumped out during the first five minutes of freeze.

This results in a short cycle and slivers of ice or small

cubes.

c) Any loss of water, whether by leak, water trail, or

loose stand pipe can cause this problem.

6. Freeze ups can be caused by 2, 3, or 4 above in any

combination. The major cause however is a dirty

(scaled up ) water system or evaporator. A thorough

cleaning will eliminate most freeze ups. The second

most common reason for freeze up is low water flow.

Always check the evaporator, and water flow first,

then go to other checks when diagnosing freeze ups.

(Size will depend on how much water is

in the reservoir.)

PREVENTATIVE MAINTENENCE: Perventative Maintenance

is the key to long equipment life and maximum efficiency.

Hoshizaki recommends preforming the following mainte-

nance steps at least annually. The PM frequency will de-

pend on the local water quality and operating conditions.

PREVENTATIVE MAINTENANCE STEPS:

1. Clean the removable air filter. Hoshizaki air-cooled units

include a front accessible, cleanable air filter. This filter

collects dirt, dust, and grease can be cleaned with warm

soapy water. Hoshizaki recommends cleaning the air filter

twice a month or more as conditions dictate.

2. Service the external water filter system (if equipped)

and check and clean inlet water valve screen.

3. Clean and sanitize the water system and bin. A cleaning

label with detailed instructions is usually located on the

inside of the front panel.

Check bearings for wear annually on Flaker/DCM.

Pull the auger and inspect evaporator, auger, and bearing

surfaces for wear.

More frequently bearing inspections

may be needed in areas with poor water quality.

5. Visually inspect the unit for loose wires, oil spots, water

drips, etc.

6. Clean & wipe exterior with a soft cloth and neutral cleaner.

STAINLESS STEEL CLEANING:

Water quality is constantly changing and local municipali-

ties are now adding higher levels of chlorine, chloramine,

and sometimes, chlorine dioxides to reduce bacteria in the

water. Stainless steel is a durable metal however it can be

suseptable to corrosion from exposure to chlorine gas.

As ice forms on a cuber evaporator, chlorine outgases and

the chlorine gas settles in the lowest point in the bin. This

gas sticks to wet surfaces and around the mouth of the bin

and forms hydrochloric acid. If this acid remains on the

stainless steel, rust colored corrosion occurs. With enough

exposure, the corrosion can pit and damage the stainless.

If rust colored corrosion is found, it should be cleaned

throughly with a non-abrasive cleaner and protected with

a stainless steel polish. Heavy corrosion will require some

effort to remove and may require the use of a cleaning

agent like “Brasso” or non-abrasive powdered cleaner like

“Zud” or “Bon Ami”. Care should be taken so as not to

scratch the stainless during the cleaning process.

CLEANING/SANITIZING PROCEDURE

A label which details the step by step cleaning/sanitizing

procedure is located on the inside front panel of the ice

machine. These instructions are also provided in the In-

struction Manual shipped with each unit. Follow these in-

structions to conduct a thorough cleaning and sanitizing of

the water system.

Annual cleanings are recommended. More frequent

cleanings may be required in bad water areas.

INLET WATER VALVE

The inlet water valve includes an 80 mesh screen to pro-

tect the water system from debris. Always check and

clear this screen during the cleaning procedure.

CLEANERS:

Hoshizaki recommends "Hoshizaki Scale Away' or "Lime-

A-Way" (by Economics Laboratory, Inc.) however any FDA

approved ice machine cleaner is acceptable. If you carry a

nickel safe cleaner, the acidic solution is weaker than nor-

mal cleaners to protect plated surfaces. You may need to

use a heavier mixture of nickel safe to cut heavier scale

deposits.

KM PRODUCTION CHECK

The steps for a cuber production check are as follows:

1. Time a complete cycle from the beginning of one

freeze cycle to the beginning of the next freeze

cycle.

2. Catch all of the ice from this freeze cycle and

weigh the total batch.

3. Divide the total minutes in a 24 hour day (1440

minutes) by the complete cycle time in minutes to

obtain the number of cycles per day.

4. Multiply the number of cycles per day by the cycle

batch weight for the cuber production per 24

hours.

(1440 • Total Cycle Time) x Ice Batch Weight=

24 Hour Production

Once you calculate the production, check the incoming wa-

ter temperature, and ambient condensing temperature at the

cuber and cross reference to performance data included in

this manual to see if the calculation falls within 10% of the

specification.

For the most accurate production check, a normal freeze

cycle should be checked. If the evaporator compartment has

been opened for service or if the unit has been cut off for a

long period of time, the first freeze cycle will be longer than

normal. Timing this cycle can result in an inaccurate produc-

tion check. To avoid this, start the unit and allow it to operate

for 10 minutes in the freeze cycle, unplug the float switch

lead and cause the unit to cycle into harvest mode. Replug

the float switch and start timing as soon as the next freeze

begins. Also remember that the evaporator compartment must

be closed during the production check. Removing the front

cover to check the ice buildup during a production check will

allow heat into the evaporator and will affect the total cycle

time and actual production.

MECHANICAL BIN CONTOL OPERATION:

The mechanical bin control is included on some modelsproduced in 2002. The mechanical assembly is located in the ice drop zone area .

When the actuator paddle is in the normal (Bin Empty) position, the bin control proximity switch will close.

1. When the switch contacts close, 7.6 K Ohms of resistance is supplied to the K4 board connector.

When ice pushes the paddle to the full right position (Bin Full), the proximity switch opens as shown above.

2. Bin control proximity switch is shown in the Bin Full position and will supply 15.8 K Ohms to the K4 board connector.

CAPACITIVE PROXIMITY BIN CONTROL: (Used on KM-1300NRF/H only)

The capacitive bin control requires DC voltage to operate. It has a seperate 24VDC power supply and switches a control relay to supply

resistance to the K4 connector. The relay contacts isolates the 24VDC from the control board which switches by resistance.

1. When the bin is empty, the resistance at K4 is 5.6 K Ohms.

2. When ice is within 1/2 to 1 inch of the sensor end, the resistance at K4 is 15.8 K Ohms to shut the unit down.

FLAKER/DCM

INSTALLATION - GENERAL

As always, you should follow the installation instructions

that are provided in the instruction manual supplied with

the unit. You will also find a yellow instruction sheet at-

tached to the top of a new unit. This sheet highlights the

installation steps. Three things are critical for a proper F/

DCM installation:

1. The water temperature should fall within the 45° F

to 90° F range.

Colder water can cause excess stress on the

auger gear motor which may activate the gear

motor overload.

2. A filter system is very important in poor water

quality areas as high mineral content can cause

premature bearing wear.

3. The unit should be level, front to back, side to

side to assure proper evaporator water level and

maximum production.

CUBELET MODELS

The DCM product produces Cubelet ice. Certain flaker mod-

els can also be converted to produce cubelet ice. This

requires changing the extruding head and cutter at the top

of the evaporator assembly. The F-450M, F-800M, and F-

2000M models are produced as cubelet models and are

designated by a - C at the end of the model number.

Converting a flaker to a cubelet maker reduces the overall

production by around 8 %. The flaker gear motor is sized to

handle the extra load of producing cubelet ice with only a

slight increase in the running amperage. The evaporator

outlet temperature and operating pressures will be similar

to the standard flaker model. Use the temperature and

pressure information provided on the standard flaker per-

formance data provided as a bench mark when diagnosing

a converted cubelet (- C) unit.

141

12/20/03

2/20/03

12/01/02

INTERNAL AUGER DESIGN

Hoshizaki Flakers and DCM’s use an internal auger system

to provide high quality crisp flakes and cubelet ice. The

evaporator cylinder and auger are made of anti-magnetic

stainless steel. This higher quality stainless steel elimnates

pitting caused by harmful minerals in the water. This main-

tains a smooth surface to reduce ristriction to ice flow

providing consistant production and quality.

The picture below is a generic breakdown of the F/DCM

evaporator assembly. The extruding head # 9 and cutter

#12 can be exchanged so that this Flaker assembly will

produce Cubelet style (chunklet) ice like the DCM applica-

tion. The sleeve type alignment bearings are pressed into

the housing # 4 and extruding head # 9. The mechanical

seal # 6 and “O” ring # 5 seal the lower end of the evapo-

rator system.

COMPONENT TECHNICAL DATA

CONTROL TRANSFORMER

Hoshizaki Flaker units include a 24 volt control transformer.

This transformer has a 115 volt primary and 24 volt

secondary and is protected by a 1Amp control fuse. (The

DCM has a dual output secondary of 10.5/24V) The 24 volt

secondary supplies power to the solid state timer board,

relay coils, inlet water valve and flush timer circuit. The

flush valve will be either 24 volts AC or DC, depending on

the model. A rectifier is provide in the flush valve circuit to

convert to DC. Without control voltage on pins 1 and 2, the

timer board will not allow the unit to start.

GEAR MOTOR PROTECTION

The auger gear motor circuit includes two overload safe-

ties. The primary safety is a manual reset, current type

protector or slow blow fuse located in the control box. This

is a time delay protection which operates if high amp draw

occurs. The secondary safety is a thermal protector which

is incorporated into the gear motor windings.

The current type gear motor safety has been replaced

with a slow blow fuse on most models. The Fuse provides

more consistant protection in low voltage applications.

GEAR MOTOR PROTECTION:

MODEL PROTECTION

F-300B & F-500B Current type protector

Later production uses a 1.5 amp fuse.

F-450M, F-800 1.5 Amp fuse

F-1000M Current type protector

Later production uses a 1.5 amp fuse.

F-1000M_F-C 2 amp fuse.

F-1001M_H 3 amp fuse.

F-2000M_F Current type protector.

F-2000M_H 10 amp fuse.

Note: Some cases require a 2 amp fuse for the F-1000M.

Gear motor failure can be expensive and it is very impor-

tant to find the cause of the failure when it is replaced.

There are several possibilities for the cause of gear motor

failure. The following check list is designed to help you find

the reason your failure occurred.

143

12/20/03

2/20/03

12/01/02

144

F-1000M GEAR MOTOR CHECKOUT

NORMAL AMPERAGE: The amperage for the F-1000M

gear motor should be 0.6~1.0 amps with no load and 1.0~1.4

amps when making ice.

Answer the following questions to discover the possible

cause for your failure:

1. Is Ambient Temperature above 45 degrees F.

2. Does the unit have the

Wrong Extruding Head

. Check

the Extruder Type. Is it a Flaker or Cubelet style. (The

cubelet style head will have smaller openings for the ice to

extrude.)

3. Does the unit have the

Wrong Cutter.

The cutter should

match the extruding head style. Flake or Cubelet.

4. Do you have a

Damaged Extruder.

Look for following

imperfections. A. Dents B. Fins Bent

C. Scale D. Other Resistance

5. Does the unit have the

Correct Auger

. Is the auger a

dual flight auger? (Double Spirals) Check the parts break-

down for the correct auger style.

6. Check the

Voltage Supply

and circuit amperage. Is this

unit on it’s own dedicated circuit? The supply voltage

should be within +/- 10% of the rated voltage when the unit

is making ice.

7. Check the

Running Voltage

at the gear motor. (While

the unit is making Ice.)

8. Inspect bearings for wear. ( Use bearing gauge ) Are

the

Bearings

OK? If the upper bearing is worn, both bear-

ings should be replaced.

9. Check Evaporator Cylinder/ Barrel for signs of scoring.

10. Is there any condensation dripping onto the Gear Mo-

tor windings? If yes, find the source and take action to

stop the moisture.

11. Is the galvanized shield mounted over the motor as-

sembly?

12. Verify that you have the proper Gear Motor Capacitor.

13. Is the

Gear Motor Locked

. Check motor winding resis-

tance.

2. WRONG GEAR MOTOR OVERLOAD / FUSE:

Check fuse size. Has the original overload reset been re-

placed with the fuse kit? The M_F Flaker requires Bussman

GMD 1.5A Fuse P/N 4A0893-04. The M_F-C Cubelet

requires Bussman GMD 2.0A Fuse P/N 4A0893-05. This

fuse is a slow blow type. Replacing it with a standard fuse

will cause the fuse to blow again.

12/20/03

2/20/03

12/01/02

Although it is common practice to install a larger fuse dur-

ing service diagnosis, you should not leave a larger fuse in

the unit when you leave the site. This could cause a seri-

ous unit failure.

3. MISWIRING

Is gear motor wired correctly and wire connections tight.

Check the wiring diagram for the proper wiring.

4. BIN CONTROL SWITCH DOES NOT OPERATE

Check the bin control operation. A bad or miswired bin

control can cause ice to back up in the spout and chute and

cause higher gear motor amperage. Is Bin Control wired

correctly and are the wire connections tight.

Make sure there are no metallic components interfering

with the magnetic bin control. Verify top panel is non-mag-

netic. Assure that the proximity switch is mount properly.

The switch must be secure and mounted level to the chute

top. Does the

Bin Control Paddle

move freely and is it

unobstructed?

As you can see, there are many factors that can cause a

gear motor to fail. A gear motor check list comes with a

service replacement part. The check list can be used as a

diagnostic tool. If the gear motor is under warranty, the

checklist should be completed and submitted with the war-

ranty claim.

GEAR MOTOR STRESS

When looking for the cause of a gear motor failure, you

should consider anything that will add stress to the assem-

bly. Stress on the gear motor will increase the gear motor

amperage and torque. The most common causes for stress

is scale on the auger surface and evaporator walls. Scale

nsulates the evaporator walls and causes reduced heat

transfer. As a result, the ice will be wet and mushy. This

poor quality ice does not extrude well and tends to pack in

the evaporator outlet.

Heavy scale build up must be removed using an acid based

cleaner which will loosen the scale. Follow the cleaning

instructions provided on the cleaning label to preform a

maintenance cleaning. If the unit has not been cleaned and

maintained frequently, it may require you to pull the auger

145

12/20/03

2/20/03

12/01/02

and clean the cylinder wall with a Scotchbrite pad & cleaner.

The extruding head surface may also have heavy scale

and can be cleaned with Scotchbrite & cleaner as well.

AUGER BEARINGS:

Bearing Type: Sleeve/Alignment,

Bearing Material: Poly/Carbon

The bearings are pressed into the top extruding head and

lower brass housing. A repress program is available

through the local Hoshizaki Distributor for undamaged ex-

truding heads and housings. The bearings should always

be replaced as a set. Return the extruding head and hous-

ing to your distributor for an exchange set or to be returned

for repressing.

BEARING INSPECTIONS:

Annual bearing inspections are recommended. More fre-

quent inspections may be necessary in poor water quality

areas. The steps for bearing inspections are as follows:

(1 ) Gain access to the ice chute head by removing the top

panel and spout connectors as necessary.

(2) Remove the thumbnuts which hold the ice chute head in

place and lift it up and off of the evaporator (take care to

place the O-ring in a safe location until you replace the

head.)

(3) Remove the stainless steel bolt holding the cutter or

breaker in place and lift off to access the extruding head

and auger shaft.

(4) Replace the bolt into the auger shaft and use it to push

the auger back and forth from left to right to check for

excessive movement.

(5) Pull the auger towards you and try to insert a .02” round

stock or pin gauge in between the back side of the auger

shaft and bearing surface. Check several locations around

the auger shaft. If the gauge will go in between the shaft

and bearing, it is time to install new bearings. Both top and

bottom bearings should be replaced if the top bearing is

worn. If there is no excessive movement in the auger shaft

and the gauge does not fit, the bearings are okay. Replace

the cutter, O-ring, ice chute head and connectors.

AUGER INSPECTION / BEARING

REPLACEMENT

A visual inspection of the auger bearing shaft surface is

also recommended annually in poor water areas. The steps

for this inspection is as follows:

Note: Clean the evaporator prior to removing the auger.

This will loosen scale around the extruding head

and allow for easier removal.

(1) Follow steps 1 through 5 of the bearing inspection pro-

cedure above.

(2) Remove the (metric) Allen head cap screws that se-

cure the extruding head in place.

(3) Thoroughly drain the water supply system.

4) Turn the cutter up-side down, replace the bolt and use

the cutter to lift the auger out of the evaporator. If heavy

scale is present the auger may be difficult to remove. In this

case, you will find it helpful to clean the evaporator system

following the instructions located on the Inside front panel,

before you attempt to remove the auger.

(5) With the auger removed, remove the cutter and slide

the extruding head from the top of the auger. Visually in-

spect the bearing surface at the top and bottom of the

auger. Also inspect the auger flight and mechanical seal for

any damage. The extruding head contains the top bearing,

the bottom bearing is pressed into the brass housing at the

bottom of the evaporator. To remove the housing:

(6) Remove the Allen screws that secure the evaporator to

the housing.

(7) Loosen the belly band screw and lift the evaporator up

Flaker Safety’s

Mechanical failures in an auger style ice machine can be

time consuming and expensive repairs. Hoshizaki has in-

corporated several safety’s in our Flaker and DCM units

which add protection against this type of failure.

The following safety’s are included in all Hoshizaki F and

DCM units:

1. Low water safety: Designed to protect against dry

operation or possible freeze up in the evaporator due to

low water flow. This safety utilizes the dual float switch

and a 90 second timer to shut down the unit when water

flow is interrupted. The unit will automatically restart when

water flow is resumed.

2. Protect relay safety: This safety incorporates a relay in

the gear motor circuit and will not allow the refrigeration

system to operate unless the gear motor is running. If the

gear motor fails during normal operation, the protect relay

shuts down the compressor to protect against evaporator

freeze-up.

3. Gear motor circuit safety’s: The gear motor has 2

additional safety’s which will operate if the gear motor is

subjected to excessive load or improper voltage. A current

type manual reset safety or slow blow fuse is located in

the control box and will trip when the gear motor amperage

exceeds normal amp draw. This acts as a primary safety

for the gear motor. A secondary internal thermal overload

and off of the housing. Holding the evaporator up, re-tighten

the belly band. This will hold the evaporator up so that you

can remove the housing.

(8) Remove the bolts that secure the housing to the gear

motor assembly and remove the brass housing. The me-

chanical seal ceramic disk and boot are pressed into the

top of the housing. Remove these parts before you ex-

change the bearings. The extruding head and brass hous-

ing will be exchanged for a repressed set at your local

distributor. When you replace the new parts, reverse the

order above. Use a light coat of food grade lubricant around

the bottom of the evaporator and on the o-ring portion of

the housing to the seal o-ring and help keep it in place as

you lower the evaporator. Inspect the mechanical seal thor-

oughly and reuse it, if it is in good shape.

148

is included in the motor windings. Both will work in con-

junction with the protect relay to shut the unit down.

4. Voltage protect relay: This relay will shut the unit off in

case of a voltage surge and automatically restart the unit

when the voltage is correct.

5. High pressure switch: All Hoshizaki ice machines in-

clude an automatic reset high pressure safety switch to

shut down the unit in case of high head pressures.

6. Fuse protection: A lamp buss-type fuse is utilized in the

control circuit. Smaller units like the DCM-240 and F-300

have a fuse in the incoming power circuit.

7. Short cycle protection timer: A 1 minute time delay is

included in the start-up sequence to protect against short

cycling the gear motor or compressor.

8. Compressor protection is provided either internally or by

means of an external motor circuit protector. This is an

automatic reset thermal type circuit breaker.

9. The F-2000 has a spout safety control to shut down the

unit if the bin control fails for any reason. This is a manual

reset safety and will notify the technician by means of a

indicator light on the control box. To reset this safety, turn

the control switch OFF and back ON. This re-sets the hold-

ing relay circuit and turns off the light.

The gear motor current protector serves as a back-up for

the bin control on other models. These safety’s protect the

Flaker or DCM models from internal failures.

DUAL FLOAT SWITCH

Hoshizaki float switch, part number 435490-01 can be used

as a universal replacement on any Hoshizaki Flaker or DCM

model in the field. It now subs for all previous float switch

numbers in our parts system.

Since the float switch is mounted into the water reservoir,

it is susceptible to scale build-up. The amount of scale

build-up will depend on the local water quality. Scale on

149

12/20/03

2/20/03

12/01/02

the switch shaft can cause the floats to stick. This will

effect the unit operation. In this case, the float switch

should be cleaned and checked.

The float switch is held in place on the top cover by a twist

lock bracket. To remove it, twist the switch flange and lift.

Soak the switch assembly in ice machine cleaner. While it

is not necessary to do so, some technicians remove the

floats from the shaft during cleaning. If you remove them,

note that the blue float is on top. Also it is important to

clearly mark the top of the floats so that they can be re-

placed correctly. (See drawing below). Installing the floats

upside down will effect the timing of the float switch op-

eration. Once clean, rinse and wipe the cleaner off and

check the switch with a good quality ohm meter.

This float switch has three wires (the black wire is com-

mon) and two separate switches. Check the top switch

by ohming out the black and red wires. When the float is up

the switch should be closed. Check the bottom switch by

ohming out the black and blue wires in the same manner. If

either switch fails, the assembly should be replaced.

FLAKER WATER FILL SYSTEM

The reservoir in a Hoshizaki auger type ice maker feeds

water by gravity flow to the evaporator cylinder. The level

of water in the reservoir is maintained by the operation of

the dual float switch.

The dual float switch assembly is made up of two reed

switches inside of a sealed shaft. The reed switch con-

tacts are operated by individual magnets attached inside of

the two separate floats.

As ice is made and extruded from the evaporator cylinder,

the water level in the reservoir drops. When the level drops,

the top float opens the top switch contacts (considered a

latching circuit). Opening these contacts allows the bot-

tom float switch control of the water control relay in the

control circuit. As the water level continues to drop, the

bottom float contacts open to de-energize the water con-

trol relay.

De-energizing the water control relay closes a circuit to

supply 24 volts to the inlet water valve solenoid. This al-

lows water to fill the reservoir. It also opens a circuit to the

timer board which starts a 90 second low water safety

shutdown timer.

When the water supply is available, the reservoir refills.

As the reservoir level rises, these two switches swap

jobs. The bottom float is now the latching circuit and thetop

float re-energizes the water control relay. This will stop

the safety timer and shut off the water flow.

If no water is available, i.e. the filter is stopped up or the

water supply is turned off, the unit cycles down and the

water valve remains energized. When the water supply is

restored, the reservoir fills and the top float switch re-

energizes the water control relay to automatically restart

the unit. This system provides a consistent water level in

the reservoir and an automatic reset low water safety

protection.

Since the float switch is mounted into the water reservoir,

it is susceptible to scale build-up. The amount of scale

build-up will depend on the local water quality. Scale on

the switch shaft can cause the floats to stick. This will

effect the unit operation. In this case, the float switch

should be cleaned and checked.

FLAKER TIMER BOARD

The solid state timer board used in Hoshizaki Flakers is a

simple electronic sequence timer. In order for the board to

sequence, certain circuits must be closed. In order to diag-

nose a bad timer board, it is necessary to check these

circuits to assure they are operating properly. If you are

trouble-shooting a timer, the first thing you should check is

the in coming control voltage. All Hoshizaki flakers have a

24 volt control transformer. The output of this transformer

is protected by a 1 amp buss type fuse. Control voltage

comes in the timer on pins 1 & 2. If you do not have 24 volts

at pins 1 & 2, check the transformer and fuse.

Now check for 24 volts across pins 7 & 8. If voltage is

present, the timer board has cycled up which indicates

there is not a problem in the timer board. The problem is in

the gear motor relay circuit. remember that there is a time

delay from the time you turn the unit on to the time it cycles

up completely. this time will be from 1 ~ 2.5 minutes, de-

pending on the model of flaker.

In order for the flaker to start up, the reservoir must be full

and both float switches must be closed. This closes the

control circuit to pins 3 & 4. Do not confuse these pins with

the line voltage terminals marked 3 & 4 on the compressor

relay located on the board. You can check this circuit with

a volt meter across the pins or by placing a jumper across

them. If the unit cycles up with the jumper in place, the

board is good and your problem is in the water relay con-

trol circuit.

Next, you should check the bin control circuit at pins 5 & 6.

Check for a closed circuit with a volt meter or place a

jumper across them. If the unit cycles up with the jumper

in place, the board is good and the bin control circuit is the

problem.

The last circuit check is across pins 10 & 11. These pins

connect to the gear motor protect relay and will shut down

the unit if the gear motor fails. Check for a closed circuit

with a volt meter or place a jumper across them. If the unit

cycles up with the jumper in place, the board is good and

the gear motor protect circuit is suspect.

Flaker Sequence of Operation

The Hoshizaki Flaker utilizes a solid state sequence timer

board to switch the components on and off as needed.

The sequence is as follows:

With proper voltage and water supplied to the Flaker and

the flush and ice switch is in the ice position, power is

supplied to the inlet water valve. The unit will not start

unless the reservoir is full and both floats on the dual float

switch are closed (in the up position). The operation is

then turned over to the bin control. If the bin control is

closed and calling for ice, the gear motor and condenser

fan motor are energized. One minute later, the compressor

starts. As the refrigeration systems cools the water in the

evaporator, ice will start to form within 2 to 5 minutes. This

depends on the inlet water temperature and ambient condi-

tions. Ice production will continue until the bin control is

satisfied (opens). The shut down process is very simple.

On the F-450, F-800, F-1000, and F-2000 units, the entire

unit shuts down within 6 seconds after the bin control

switch opens. On the F-300 and F-500, approximately 90

seconds after the bin control switch opens, the compres-

sor stops, on minute later the gear motor and condenser

fan motor stop. This sequence of operation is accom-

plished through a series of timers within the solid state

timer board.

DCM SEQUENCE OF OPERATION

DCM sequence for the ice making unit is similar to the F-

500, with a delay of the compressor at start up and a delay

of the gear motor at shut down.

A periodic flush is also incorporated in the DCM units. All

DCM models have periodic agitation in the bin to eliminate

ice bridging. The DCM- 240 model uses a solid state relay to

turn the gear motor for .2 seconds every 90 minutes. On

DCM-500 and 750 models, the solid state timer board will

start the agitation motor for .6 seconds every 12 seconds

of accumulated dispensing time.

FLAKER/DCM PRODUCTION CHECK

Checking the production on a F/DCM is a simple process.

To check the production you will need a bucket or pan to

catch the ice and a set of scales to weigh the ice. After the

unit has operated for 10 to 20 minutes, catch the ice pro-

duction for 10 full minutes. Weigh the ice to establish the

batch weight. Multiply the batch weight by 144 for the total

production in 24 hours. Some prefer to catch the ice for 20

minutes and multiply the weight by 72 for a more realistic

production check. It is true that a longer catch is more

accurate, however, it doubles your test time and may only

show a 1 to 2% difference in production. Performing a

production check is an excellent way to prove proper F/

DCM operation.

FLAKER PERIODIC FLUSH

Beginning with the F-450M and larger flakers, a periodic

flush cycle is included. A 12 hour timer will cycle the unit

down and open the flush valve which allows the complete

water system to drain. The unit will remain off for 20 min-

utes which allows any ice remaining in the evaporator to

melt and flush the evaporator walls and mechanical seal

out. The inlet water valve is not energized during this flush

period. The unit will automatically restart after 20 minutes

on the flush timer.

The F-500 will flush when the bin control is open.
