Location of Ice Machine

The location selected for the ice machine must meet the

following criteria. If any of these criteria are not met,

select another location.

• The location must be free of airborne and other

contaminants.

• The air temperature must be at least 35°F (1.6°C),

but must not exceed 110°F (43.4°C).

• Remote air cooled - The air temperature must be at

least -20°F (-29°C), but must not exceed 120°F

(49°C)

• The location must not be near heat-generating

equipment or in direct sunlight and must be protected

from weather.

• The location must not obstruct air flow through or

around the ice machine. Refer to the chart below for

clearance requirements.

Ice Machine Heat of Rejection

Ice machines, like other refrigeration equipment, reject

heat through the condenser. It is helpful to know the

amount of heat rejected by the ice machine when sizing

air conditioning equipment where self-contained air-

cooled ice machines are installed.

This information is also necessary when evaluating the

benefits of using water-cooled or remote condensers to

reduce air conditioning loads. The amount of heat added

to an air conditioned environment by an ice machine

using a water-cooled or remote condenser is negligible.

Knowing the amount of heat rejected is also important

when sizing a cooling tower for a water-cooled

condenser. Use the peak figure for sizing the cooling

tower.

Electrical Service

GENERAL

VOLTAGE

The maximum allowable voltage variation is ±10% of the

rated voltage at ice machine start-up (when the electrical

load is highest).

All electrical work, including wire routing and grounding,

must conform to local, state and national electrical

codes. The following precautions must be observed:

• The ice machine must be grounded.

• A separate fuse/circuit breaker must be provided for

each ice machine.

• A qualified electrician must determine proper wire

size dependent upon location, materials used and

length of run (minimum circuit ampacity can be used

to help select the wire size).

• The maximum allowable voltage variation is +/-10 of

the rated voltage at ice machine start-up (when the

electrical load is highest).

• Check all green ground screws in the control box and

verify they are tight before starting the ice machine.

Incorrect polarity can lead to erratic ice machine

operation and a safety issue. This is especially critical on

230 volt / 50 cycle ice machines.

Fuse/Circuit Breaker

A separate fuse/circuit breaker must be provided for

each ice machine. Circuit breakers must be H.A.C.R.

rated (does not apply in Canada).

MINIMUM CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the

wire size of the electrical supply. (Minimum circuit

ampacity is not the ice machine’s running amp load.)

The wire size (or gauge) is also dependent upon

location, materials used, length of run, etc., so it must be

determined by a qualified electrician.

ELECTRICAL REQUIREMENTS

Refer to Ice Machine Model/Serial Plate for voltage/

amperage specifications.

!

Warning

All wiring must conform to local, state and national

codes.

!

Warning

The ice machine must be grounded in accordance

with national and local electrical codes.

Important

Observe correct polarity of incoming line voltage.

Water Supply and Drain Requirements

WATER SUPPLY

Local water conditions may require treatment of the

water to inhibit scale formation, filter sediment, and

remove chlorine odor and taste.

WATER INLET LINES

Follow these guidelines to install water inlet lines:

• Do not connect the ice machine to a hot water

supply. Be sure all hot water restrictors installed for

other equipment are working. (Check valves on sink

faucets, dishwashers, etc.)

• If water pressure exceeds the maximum

recommended pressure (80 psi), obtain a water

pressure regulator from your Manitowoc distributor.

• Install a water shut-off valve for both the ice making

and condenser water lines.

• Insulate water inlet lines to prevent condensation.

DRAIN CONNECTIONS

Follow these guidelines when installing drain lines to

prevent drain water from flowing back into the ice

machine and storage bin:

• Drain lines must have a 1.5 inch drop per 5 feet of

run (2.5 cm per meter), and must not create traps.

• The floor drain must be large enough to

accommodate drainage from all drains.

• Run separate bin and ice machine drain lines.

Insulate them to prevent condensation.

• Vent the bin and ice machine drain to the

atmosphere. Do not vent the condenser drain on

water-cooled models.

Cooling Tower Applications

(Water-Cooled Models)

A water cooling tower installation does not require

modification of the ice machine. The water regulator

valve for the condenser continues to control the

refrigeration discharge pressure.

It is necessary to know the amount of heat rejection, and

the pressure drop through the condenser and water

valves (inlet and outlet) when using a cooling tower on

an ice machine.

• Water entering the condenser must not exceed 90°F

(32.2°C).

• Water flow through the condenser must not exceed 5

gallons (19 liters) per minute.

• Allow for a pressure drop of 7 psi (48 kPA) between

the condenser water inlet and the outlet of the ice

machine.

• Water exiting the condenser must not exceed 110°F

(43.3°C).

Important

If you are installing a Manitowoc Arctic Puref water

filter system, refer to the Installation Instructions

supplied with the filter system for ice making water

inlet connections.

!

Caution

Do not apply heat to water valve inlet fitting. This will

damage plastic valve body.

Installation Instructions Section 2

2-16 Part Number 80-1620-3

GENERAL

Condensers must be mounted horizontally with the fan

motor on top.

Remote condenser installations consist of vertical and

horizontal line sets between the ice machine and the

condenser. When combined, they must fit within

approved specifications. The following guidelines,

drawings and calculation methods must be followed to

verify a proper remote condenser installation.

GUIDELINES FOR ROUTING LINE SETS

First, cut a 2.5" (6.35 cm) circular hole in the wall or roof

for tubing routing. The line set end with the 90° bend will

connect to the ice machine. The straight end will connect

to the remote condenser.

Follow these guidelines when routing the refrigerant

lines. This will help insure proper performance and

service accessibility.

1. Optional - Make the service loop in the line sets (as

shown below). This permits easy access to the ice

machine for cleaning and service. Do not use hard

rigid copper at this location.

2. Required - Do not form traps in the refrigeration lines

(except the service loop). Refrigerant oil must be

free to drain toward the ice machine or the

condenser. Route excess tubing in a supported

downward horizontal spiral (as shown below). Do

not coil tubing vertically.

3. Required - Keep outdoor refrigerant line runs as

short as possible.

Routing Line Sets

!

Caution

The 60 month compressor warranty (including the

36 month labor replacement warranty) will not apply

if the remote ice machine is not installed according

to specifications.

This warranty also will not apply if the refrigeration

system is modified with a condenser, heat reclaim

device, or other parts or assemblies not

manufactured by Manitowoc Ice, Inc., unless

specifically approved in writing by Manitowoc Ice,

Inc.

CALCULATING REMOTE CONDENSER

INSTALLATION DISTANCES

Line Set Length

The maximum length is 100' (30.5 m).

The ice machine compressor must have the proper oil

return. The receiver is designed to hold a charge

sufficient to operate the ice machine in ambient

temperatures between -20°F (-29°C) and 120°F (49°C),

with line set lengths of up to 100' (30.5 m).

Line Set Rise/Drop

The maximum rise is 35' (10.7 m).

The maximum drop is 15' (4.5 m).

Calculated Line Set Distance

The maximum calculated distance is 150' (45.7 m).

Line set rises, drops, horizontal runs (or combinations of

these) in excess of the stated maximums will exceed

compressor start-up and design limits. This will cause

poor oil return to the compressor.

Make the following calculations to make sure the line set

layout is within specifications.

1. Insert the measured rise into the formula below.

Multiply by 1.7 to get the calculated rise.

(Example: A condenser located 10 feet above the

ice machine has a calculated rise of 17 feet.)

2. Insert the measured drop into the formula below.

Multiply by 6.6 to get the calculated drop.

(Example. A condenser located 10 feet below the

ice machine has a calculated drop of 66 feet.)

3. Insert the measured horizontal distance into the

formula below. No calculation is necessary.

4. Add together the calculated rise, calculated drop,

and horizontal distance to get the total calculated

distance. If this total exceeds 150' (45.7 m), move

the condenser to a new location and perform the

calculations again.

Maximum Line Set Distance Formula

!

Caution

If a line set has a rise followed by a drop, another

rise cannot be made. Likewise, if a line set has a

drop followed by a rise, another drop cannot be

made.

LENGTHENING OR REDUCING LINE SET LENGTHS

In most cases, by routing the line set properly,

shortening will not be necessary. When shortening or

lengthening is required, do so before connecting the line

set to the ice machine or the remote condenser. This

prevents the loss of refrigerant in the ice machine or

condenser.

The quick connect fittings on the line sets are equipped

with Schraeder valves. Use these valves to recover any

vapor charge from the line set. When lengthening or

shortening lines follow good refrigeration practices,

purge with nitrogen and insulate all tubing. Do not

change the tube sizes. Evacuate the lines and place

about 5 oz (143g) of vapor refrigerant charge in each

line.

CONNECTING A LINE SET

1. Remove the dust caps from the line set, condenser

and ice machine.

2. Apply refrigeration oil to the threads on the quick

disconnect couplers before connecting them to the

condenser.

3. Carefully thread the female fitting to the condenser

or ice machine by hand.

4. Tighten the couplings with a wrench until they

bottom out.

5. Turn an additional 1/4 turn to ensure proper brass-

to-brass seating. Torque to the following

specifications:

6. Check all fittings and valve caps for leaks.

7. Make sure Schraeder cores are seated and

Schraeder caps are on and tight.

REMOTE RECEIVER SERVICE VALVE

The receiver service valve is closed during shipment.

Open the valve prior to starting the ice machine.

1. Remove the top and left side panels.

2. Remove the receiver service valve cap.

3. Backseat (open) the valve.

4. Reinstall the cap and panels.

Remote Ice Machine Usage with Non-Manitowoc Multi-Circuit Condensers

WARRANTY

The sixty (60) month compressor warranty, including

thirty six (36) month labor replacement warranty, shall

not apply when the remote ice machine is not installed

within the remote specifications. The foregoing warranty

shall not apply to any ice machine installed and/or

maintained inconsistent with the technical instructions

provided by Manitowoc Ice, Inc. Performance may vary

from Sales specifications. S-Model ARI certified

standard ratings only apply when used with a Manitowoc

remote condenser.

If the design of the condenser meets the specifications,

Manitowoc’s only approval is for full warranty coverage

to be extended to the Manitowoc manufactured part of

the system. Since Manitowoc does not test the

condenser in conjunction with the ice machine,

Manitowoc will not endorse, recommend, or approve the

condenser, and will not be responsible for its

performance or reliability.

HEAD PRESSURE CONTROL VALVE

Any remote condenser connected to a Manitowoc S-

Model Ice Machine must have a head pressure control

valve #836809-3 (available from Manitowoc Distributors)

installed on the condenser package. Manitowoc will not

accept substitute “off the shelf” head pressure control

valves.

FAN MOTOR

The condenser fan must be on during the complete ice

machine freeze cycle (do not cycle on fan cycle control).

The ice maker has a condenser fan motor circuit for use

with a Manitowoc condenser. It is recommended that this

circuit be used to control the condenser fan(s) on the

multi-circuit condenser to assure it is on at the proper

time. Do not exceed the rated amps for the fan motor

circuit listed on the ice machine’s serial tag.

INTERNAL CONDENSER VOLUME

The multi-circuit condenser internal volume must not be

less than or exceed that used by Manitowoc (see chart

on next page). Do not exceed internal volume and try

to add charge to compensate, as compressor failure

will result.

CONDENSER ∆T

∆T is the difference in temperature between the

condensing refrigerant and entering air. The ∆T should

be 15 to 20°F (-9.4 to -6.6°C) at the beginning of the

freeze cycle (peak load conditions) and drop down to 12

to 17°F (-11.1 to -8.3°C) during the last 75% of the

freeze cycle (average load conditions).

REFRIGERANT CHARGE

Remote ice machines have the serial plate refrigerant

charge (total system charge) located in the ice maker

section. (Remote condensers and line sets are supplied

with only a vapor charge.)

QUICK CONNECT FITTINGS

The ice machine and line sets come with quick connect

fittings. It is recommended that matching quick connects

(available through Manitowoc Distributors) be installed in

the multi-circuit condenser, and that a vapor “holding”

charge (5 oz.) of proper refrigerant be added to the

condenser prior to connection of the ice machine or line

set to the condenser.

Important

Manitowoc warrants only complete new and unused

remote packages. Guaranteeing the integrity of a

new ice machine under the terms of our warranty

prohibits the use of pre-existing (used) tubing or

condensers.

!

Caution

Do not use a fan cycling control to try to maintain

discharge pressure. Compressor failure will result.

!

Caution

Never add more than nameplate charge to ice

machine for any application.

Sequence Of Operation

NOTE: The toggle switch must be in the ice position and

the water curtain must be in place on the evaporator

before the ice machine will start.

INITIAL START-UP OR START-UP AFTER

AUTOMATIC SHUT-OFF

1. Water Purge

Before the compressor starts, the water pump and water

dump solenoid are energized for 45 seconds, to

completely purge the ice machine of old water. This

feature ensures that the ice making cycle starts with

fresh water.

The harvest valve(s) is also energized during water

purge, although it stays on for an additional 5 seconds

(50 seconds total on time) during the initial refrigeration

system start-up.

When Used - The air compressor energizes for the last

10 seconds of the cycle.

2. Refrigeration System Start-Up

The compressor starts after the 45 second water purge,

and it remains on throughout the entire Freeze and

Harvest Sequences. The water fill valve is energized at

the same time as the compressor. The harvest valve(s)

remains on for 5 seconds during initial compressor start-

up and then shuts off.

At the same time the compressor starts, the condenser

fan motor (air-cooled models) is supplied with power

throughout the entire Freeze and Harvest Sequences.

The fan motor is wired through a fan cycle pressure

control, therefore it may cycle on and off. (The

compressor and condenser fan motor are wired through

the contactor. As a result, anytime the contactor coil is

energized, the compressor and fan motor are supplied

with power.)

FREEZE SEQUENCE

3. Prechill

The compressor is on for 30 seconds (60 seconds initial

cycle) prior to water flow, to prechill the evaporator. The

water fill valve remains on until the water level probe is

satisfied.

4. Freeze

The water pump restarts after the prechill. An even flow

of water is directed across the evaporator and into each

cube cell, where it freezes. The water fill valve will cycle

on and then off one more time to refill the water trough.

When sufficient ice has formed, the water flow (not the

ice) contacts the ice thickness probe. After

approximately 10 seconds of continual water contact,

the harvest sequence is initiated. The ice machine

cannot initiate a harvest sequence until a 6 minute

freeze lock has been surpassed.

NOTE: Freeze lock is bypassed after moving the toggle

switch from OFF to ICE position for the first cycle only.

Section 3 Ice Machine Operation

Part Number 80-1620-3 3-3

HARVEST SEQUENCE

5. Water Purge

The harvest valve(s) opens at the beginning of the water

purge to divert hot refrigerant gas into the evaporator.

The water pump continues to run, and the water dump

valve energizes for 45 seconds to purge the water in the

sump trough. The water fill valve energizes (turns on)

and de-energizes (turns off) strictly by time. The water fill

valve energizes for the last 15 seconds of the 45-second

water purge.

After the 45 second water purge, the water fill valve,

water pump and dump valve de-energize. (Refer to

“Water Purge Adjustment” for details.)

6. Harvest

The harvest valve(s) remains open and the refrigerant

gas warms the evaporator causing the cubes to slide, as

a sheet, off the evaporator and into the storage bin. The

sliding sheet of cubes swings the water curtain out,

opening the bin switch.

The momentary opening and re-closing of the bin switch

terminates the harvest sequence and returns the ice

machine to the freeze sequence (Step 3 - 4.)

When Used - The air compressor energizes after 35

seconds and remains energized throughout the entire

harvest cycle. The air compressor will automatically

energize for 60 seconds when the harvest cycle time

exceeded 75 seconds in the previous cycle.

AUTOMATIC SHUT-OFF

7. Automatic Shut-Off

When the storage bin is full at the end of a harvest

sequence, the sheet of cubes fails to clear the water

curtain and will hold it open. After the water curtain is

held open for 30 seconds, the ice machine shuts off. The

ice machine remains off for 3 minutes before it can

automatically restart.

The ice machine remains off until enough ice has been

removed from the storage bin to allow the ice to fall clear

of the water curtain. As the water curtain swings back to

the operating position, the bin switch re-closes and the

ice machine restarts (steps 1 - 2), provided the 3 minute

delay period is complete.

SAFETY TIMERS

The control board has the following non-adjustable

safety timers:

• The ice machine is locked into the freeze cycle for 6

minutes before a harvest cycle can be initiated.

Freeze lock is bypassed after moving the toggle

switch from OFF to ICE position for the first cycle

only.

• The maximum freeze time is 60 minutes at which

time the control board automatically initiates a

harvest sequence (steps 5 & 6).

• The maximum harvest time is 3.5 minutes at which

time the control board automatically initiates a freeze

sequence (steps 3 & 4).

WARM WATER RINSE CYCLE

Closing the back of the evaporator allows ice to build up

on the rear of the evaporator and the plastic evaporator

frame parts. After 200 freeze/harvest cycles have been

complete the control board will initiate a warm water

rinse.

After the 200th harvest cycle ends:

• The Clean and Harvest LED’s energize to indicate

the ice machine is in a warm water rinse.

• The compressor and harvest valve remain

energized.

• The water pump energizes.

• The water inlet valve energizes until water contacts

the water level probe.

• The compressor and harvest valve warm the water

for 5 minutes, then de-energize.

• The water pump remains energized for an additional

5 minutes (10 minute total on time) then de-

energizes.

NOTE: The warm water rinse cycle can be terminated by

moving the toggle switch to the OFF position, then back to ICE.

Operational Checks

GENERAL

Manitowoc ice machines are factory-operated and

adjusted before shipment. Normally, new installations do

not require any adjustment.

To ensure proper operation, always follow the

Operational Checks:

• when starting the ice machine for the first time

• after a prolonged out of service period

• after cleaning and sanitizing

NOTE: Routine adjustments and maintenance

procedures are not covered by the warranty.

WATER LEVEL

The water level sensor is set to maintain the proper

water level above the water pump housing. The water

level is not adjustable. If the water level is incorrect,

check the water level probe for damage (probe bent,

etc.). Clean the water level probe with ice machine

cleaner, rinse thoroughly and re-check operation. Repair

or replace the probe as necessary.

ICE THICKNESS CHECK

The ice thickness probe is factory-set to maintain the ice

bridge thickness at 1/8" (.32 cm).

NOTE: Make sure the water curtain is in place when

performing this check. It prevents water from splashing

out of the water trough.

1. Inspect the bridge connecting the cubes. It should

be about 1/8" (.32 cm) thick.

2. If adjustment is necessary, turn the ice thickness

probe adjustment screw clockwise to increase

bridge thickness, counterclockwise to decrease

bridge thickness. Set at 1/4” gap between ice

machine and evaporator as starting point, then

adjust to achieve a 1/8” bridge thickness.

NOTE: Turning the adjustment 1/3 of a turn will change

the ice thickness about 1/16" (1.5 mm).

Ice Thickness Check

3. Make sure the ice thickness probe wire and the

bracket do not restrict movement of the probe.

HARVEST SEQUENCE WATER PURGE

The harvest sequence water purge adjustment may be

used when the ice machine is hooked up to special

water systems, such as a de-ionized water treatment

system.

• The harvest sequence water purge is factory set for

45 seconds. Repositioning the jumper will set the

harvest water purge to 0 seconds. This setting does

not affect the SeCs or AuCs (cleaning) sequences.

• During the harvest sequence water purge, the water

fill valve energizes and de-energizes by time. The

water purge must be at the factory setting of 45

seconds for the water fill valve to energize during the

last 15 seconds of the water purge. If it is set to less

than 45 seconds, the water fill valve will not energize

during the water purge.

Water Purge Adjustment

For your safety and to eliminate errors, we recommend

that a qualified service technician make the harvest

water purge adjustment.

!

Warning

Disconnect electric power to the ice machine at the

electrical disconnect before proceeding.

Important

The harvest sequence water purge is factory-set at

45 seconds. A shorter purge setting (with standard

water supplies such as city water) is not

recommended. This can increase water system

cleaning and sanitizing requirements.

Section 4

Maintenance

General

You are responsible for maintaining the ice machine in

accordance with the instructions in this manual.

Maintenance procedures are not covered by the

warranty.

We recommend that you perform the following

maintenance procedures a minimum of once every six

months to ensure reliable, trouble-free operation and

maximum ice production.

Ice Machine Inspection

Check all water fittings and lines for leaks. Also, make

sure the refrigeration tubing is not rubbing or vibrating

against other tubing, panels, etc.

Do not put anything (boxes, etc.) on the sides or back of

the ice machine. There must be adequate airflow

through and around the ice machine to maximize ice

production and ensure long component life.

Exterior Cleaning

Clean the area around the ice machine as often as

necessary to maintain cleanliness and efficient

operation. Use cleaners designed for use with stainless

steel products.

Sponge any dust and dirt off the outside of the ice

machine with mild soap and water. Wipe dry with a

clean, soft cloth.

Heavy stains should be removed with stainless steel

wool. Never use plain steel wool or abrasive pads. They

will scratch the panels.

Cleaning the Condenser

GENERAL

A dirty condenser restricts airflow, resulting in

excessively high operating temperatures. This reduces

ice production and shortens component life. Clean the

condenser at least every six months. Follow the steps

below.

1. The washable aluminum filter on self-contained ice

machines is designed to catch dust dirt lint and

grease. Clean the filter with a mild soap and water.

2. Clean the outside of the condenser with a soft brush

or a vacuum with a brush attachment. Be careful not

to bend the condenser fins.

3. Shine a flashlight through the condenser to check

for dirt between the fins. If dirt remains:

A. Blow compressed air through the condenser fins

from the inside. Be careful not to bend the fan

blades.

B. Use a commercial condenser coil cleaner.

Follow the directions and cautions supplied with

the cleaner.

Warning

If you do not understand the procedures or the

safety precautions that must be followed, call your

local Manitowoc service representative to perform

the maintenance procedures for you.

!

Warning

Disconnect electric power to the ice machine and

the remote condensing unit at the electric service

switch before cleaning the condenser.

!

Warning

Disconnect electric power to the ice machine head

section and the remote condensing unit at the

electric service switches before cleaning the

condenser.

Warning

The condenser fins are sharp. Use care when

cleaning them.

Maintenance Section 4

4-2 Part Number 80-1620-3

4. Straighten any bent condenser fins with a fin comb.

Straighten Bent Condenser Fins

5. Carefully wipe off the fan blades and motor with a

soft cloth. Do not bend the fan blades. If the fan

blades are excessively dirty, wash with warm, soapy

water and rinse thoroughly.

Water-Cooled Condenser

and Water Regulating Valve

Symptoms of restrictions in the condenser water circuit

include:

• Low ice production

• High water consumption

• High operating temperatures

• High operating pressures

If the ice machine is experiencing any of these symptoms,

the water-cooled condenser and water regulating valve

may require cleaning due to scale build-up.

Because the cleaning procedures require special pumps

and cleaning solutions, qualified maintenance or service

personnel must perform them.

AlphaSan

The goal of AlphaSan is to keep the plastic surfaces of

an ice machine cleaner, by reducing or delaying the

formation of bio-film. The active ingredient in

AlphaSan is the element silver in the form of silver ions

(Ag+). AlphaSan slowly releases silver ions via an ion

exchange mechanism. When AlphaSan is

compounded directly into a plastic part, a controlled

release of silver ions from the surface is regulated to

maintain an effective concentration at or near the

surface of the plastic ice machine part. AlphaSan’s

unique ability to effectively control the release of silver

not only protects against undesired discoloration of the

plastic, but also will last the life of the plastic part.

Although AlphaSan helps prevent bio-film build up it

does not eliminate the need for periodic cleaning and

maintenance. AlphaSan has no adverse effect on the

taste of the ice or beverage.

!

Caution

If you are cleaning the condenser fan blades with

water, cover the fan motor to prevent water damage

and disconnect electrical power.

Guardianf

Slime is a leading cause of ice machine breakdowns and

biological growth is a health concern. The Guardianf

system releases chlorine dioxide on a controlled basis to

inhibit the growth of bacteria and fungi that form slime

and cause malodors in the food zone of ice machines.

The Guardianf will not control mineral or other water

borne buildup. Your water quality will determine the

length of time before mineral buildup affects ice machine

performance. Mineral buildup must be removed as often

as necessary to ensure trouble-free operation of the ice

machine.

The Guardianf sachet holder is included with the sachet

packets. Refer to installation/replacement procedure to

Safety Limit Feature

In addition to the standard safety controls, such as the

high pressure cutout, your Manitowoc ice machine

features built-in safety limits which will stop the ice

machine if conditions arise which could cause a major

component failure.

Before calling for service, re-start the ice machine using

the following procedure:

1. Move the ICE/OFF/CLEAN switch to OFF and then

back to ICE.

A. If the safety limit feature has stopped the ice

machine, it will restart after a short delay.

Proceed to step 2.

B. If the ice machine does not restart, see “Ice

machine does not operate” on the previous

page.

2. Allow the ice machine to run to determine if the

condition is recurring.

A. If the ice machine stops again, the condition has

recurred. Call for service.

B. If the ice machine continues to run, the condition

has corrected itself. Allow the ice machine to

continue running.
