To the Installer

Each unit requires one power supply for each data
label on the unit. Check the data label(s) on the
freezer for branch circuit overcurrent protection or
fuse, circuit ampacity, and other electrical
specifications. Refer to the wiring diagram provided
inside of the electrical box for proper power
connections.

Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided
with a hand shut-off valve. On the underside of the
base pan, two 3/8” I.P.S. (for single-head units) or
two 1/2” I.P.S. (for double-head units) water
connections for inlet and outlet have been provided
for easy hook-up. 1/2” inside diameter water lines
should be connected to the machine. (Flexible lines
are recommended, if local codes permit.) Depending
on local water conditions, it may be advisable to
install a water strainer to prevent foreign substances
from clogging the automatic water valve. There will
be only one water “in” and one water “out”
connection for both single-head and double-head
units. DO NOT install a hand shut-off valve on the
water “out” line! Water should always flow in this
order: first, through the automatic water valve;
second, through the condenser; and third, through
the outlet fitting to an open trap drain.

CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!

This unit is provided with an equipotential
grounding lug that is to be properly attached to the
rear of the frame by the authorized installer. The
installation location is marked by the equipotential
bonding symbol (5021 of IEC 60417-1) on both the
removable panel and the equipment's frame.

A back flow prevention device is
required on the incoming water connection side.
Please refer to the applicable National, State, and
local codes for determining the proper configuration.

Electrical Connections
In the United States, this equipment is intended to

purpose of the NEC code is the practical
safeguarding of persons and property from hazards
arising from the use of electricity. This code contains
provisions considered necessary for safety. In all
other areas of the world, equipment should be
installed in accordance with the existing local codes.
Please contact your local authorities.
FOLLOW YOUR LOCAL ELECTRICAL CODES!

To the Installer

Stationary appliances which are not
equipped with a power cord and a plug or
another device to disconnect the appliance
from the power source must have an all-pole
disconnecting device with a contact gap of
at least 3 mm installed in the external
installation.

Appliances that are permanently connected
to fixed wiring and for which leakage
currents may exceed 10 mA, particularly
when disconnected or not used for long
periods or during initial installation, shall
have protective devices such as a GFI, to
protect against the leakage of current,
installed by the authorized personnel to the
local codes.

Model 8756

Supply cords used with this unit shall be
oil-resistant, sheathed flexible cable not
lighter than ordinary polychloroprene or other equivalent synthetic elastomer-sheathed
cord (Code designation 60245 IEC 57) installed with the proper cord anchorage to
relieve conductors from strain, including
twisting, at the terminals and protect the insulation of the conductors from abrasion.

Refrigerant

If the supply cord is damaged, it must be
replaced by an authorized Taylor service
technician in order to avoid a hazard.

However, any gas under pressure is potentially
hazardous and must be handled with caution.

In consideration of our environment, Taylor
uses only HFC refrigerants. The HFC refrigerant
used in this unit is R404A. This refrigerant is
generally considered non-toxic and non-flammable,
with an Ozone Depleting Potential (ODP) of zero (0).

NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.

Use only R404A refrigerant that conforms
to the AHRI standard 700 specification. The use of
any other refrigerant may expose users and
operators to unexpected safety hazards.

Beater Rotation

Refrigerant liquid sprayed onto the skin may
cause serious damage to tissue. Keep eyes and skin
protected. If refrigerant burns should occur, flush
immediately with cold water. If burns are severe,
apply ice packs and contact a physician
immediately.

Beater rotation must be clockwise as viewed
looking into the freezing cylinder.

The following procedures must be
performed by an authorized Taylor service
technician.

Taylor reminds technicians to be cautious of
government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory Service Department.

To correct the rotation on a three-phase unit,
interchange any two incoming power supply lines at
freezer main terminal block only.

WARNING: R404A refrigerant used in
conjunction with polyolester oils is extremely
moisture absorbent. When opening a refrigeration
system, the maximum time the system is open must
not exceed 15 minutes. Cap all open tubing to
prevent humid air or water from being absorbed by
the oil.

To correct rotation on a single-phase unit, change
the leads inside the beater motor. (Follow the
diagram printed on the motor.)
Electrical connections are made directly to the
terminal block provided in the main control box.

as unsorted municipal waste. The user is
responsible for returning the unit to the appropriate
collection facility, as specified by your local code.
For additional information regarding applicable local
disposal laws, please contact the municipal waste
facility and/or local authorized Taylor distributor.

Compressor Warranty Disclaimer
The refrigeration compressor(s) on this unit are
warranted for the term stated in the Limited
Warranty section in this manual. However, due to
the Montreal Protocol and the U.S. Clean Air Act
Amendments of 1990, many new refrigerants are
being tested and developed, thus seeking their way
into the service industry. Some of these new
refrigerants are being advertised as drop-in
replacements for numerous applications. It should
be noted that in the event of ordinary service to this
unit's refrigeration system, only the refrigerant
specified on the affixed data label should be
used. The unauthorized use of alternate refrigerants
will void your Taylor compressor warranty. It is the
unit owner's responsibility to make this fact known to
any technician he employs.

This Operator's Manual should be read before
operating or performing any maintenance on the
unit.
Your Taylor unit will NOT compensate for and/or
correct any errors made during the set-up or filling
operations. Thus, the initial assembly, set-up, and
priming procedures are of extreme importance. It is
strongly recommended that all personnel
responsible for the unit's operation, including
assembly and disassembly, go through these
procedures together in order to be properly trained
and to make sure that all understand their role in
using and maintaining the unit.
In the event you should require technical assistance,
please contact your local authorized Taylor
Distributor.

It should also be noted that Taylor does not warrant
the refrigerant used in its equipment. For example, if
the refrigerant is lost during the course of ordinary
service to this unit, Taylor has no obligation to either
supply or provide replacement refrigerant either at
billable or unbillable terms. Taylor will recommend a
suitable replacement if the original refrigerant is
banned, obsoleted, or no longer available during the
five (5) year Taylor warranty of the compressor.

Note: Your Taylor warranty is valid only if the parts
are authorized Taylor parts, purchased from the
local authorized Taylor Distributor, and only if all
required service work is provided by an authorized
Taylor service technician. Taylor reserves the right
to deny warranty claims on units or parts if
non-Taylor approved parts or incorrect refrigerant
were installed in the unit, system modifications were
performed beyond factory recommendations, or it is
determined that the failure was caused by abuse,
misuse, neglect, or failure to follow all operating
instructions. For full details of your Taylor Warranty,
please see the Limited Warranty section in this
manual.

From time-to-time Taylor may test new refrigerant
alternates. Should a new refrigerant alternate prove,
through Taylor's testing, that it would be accepted as
a drop-in replacement for this unit, then the
disclaimer in this “Compressor Warranty Disclaimer”
section will not apply to the use of the alternate
refrigerant approved by Taylor.
To find out the current status of an alternate
refrigerant as it relates to your compressor warranty,
call Taylor or your local authorized Taylor distributor.
Be prepared to provide the Model/Serial Number of
the unit in question.

If the crossed out wheeled bin symbol is
affixed to this unit, it signifies that this unit is
compliant with the EU Directives as well as other
similar end of life legislation in effect after August
13, 2005. Therefore, it must be collected separately
after its use is completed, and cannot be disposed

Symbol Definitions

Reset Button

To better communicate in the International arena,
the words on many of our operator switches and
buttons have symbols to indicate their functions.
Your Taylor equipment is designed with these
International symbols.

The reset button is located in the decorative plate
above the SOFTECH controls. The reset protects
the beater motor from an overload condition. Should
an overload occur, the reset mechanism will trip. To
properly reset the freezer, press the AUTO key to
cancel the cycle. Turn the power switch to the OFF
position. Press the reset button firmly. Turn the
power switch to the ON position. Press the WASH
key and observe the freezer's performance. The
beater motor should be turning the drive shaft in a
clockwise (from operator end) direction without
binding.

= AUTO
= ON
= OFF

= WASH

If it is turning properly, press the WASH key to
cancel the cycle. Press the AUTO key on both sides
to resume normal operation. If the freezer shuts
down again, contact a service technician.

= PUMP

MIX REF

Power Switch
When placed in the ON position, the power switch
allows SOFTECH control panel operation.

Standby

Indicator Lights MIX LOW and MIX OUT

During long “No Sale” periods it becomes necessary
to warm the product in the freezing cylinder to
approximately 35_ to 40_F (1.7_to 4.4_C) to prevent
overbeating and product breakdown.
When the STANDBY key is pressed, the light comes
on, indicating the CTR (Cylinder Temperature
Retention System) has been activated. In the
STANDBY mode, the WASH, PUMP, and AUTO
functions are automatically cancelled. The MIX REF
function is automatically locked in to maintain the
mix in the cabinet.

When the MIX LOW light begins to flash, the mix
tank has a low supply of mix and should be refilled
as soon as possible. When the MIX OUT light
begins to flash, it indicates the mix tank has been
almost completely exhausted and has an insufficient
supply of mix to operate the freezer. At this time, the
STANDBY and AUTO modes are locked out and the
freezer shuts down. To initiate the refrigeration
system, add mix to the tank and press the AUTO
key. The freezer will automatically begin operation.

Important: To the Operator

To resume normal operation, press the AUTO key.
When the unit cycles off, the product in the freezing
cylinder will be at serving viscosity.

Adjustable Draw Handle

When the WASH key is pressed, the light comes on,
indicating beater motor operation. The STANDBY or
AUTO modes must be cancelled first to activate the
WASH mode.

This unit features an adjustable draw handle to
provide the best portion control, giving a better,
consistent quality to your product and controlling
costs. The draw handle should be adjusted to
provide a flow rate of 5 to 7-1/2 oz. of product by
weight per 10 seconds. To increase the flow rate,
turn the screw counterclockwise. To decrease the
flow rate, turn the screw clockwise.

Auto
When the AUTO key is pressed, the light comes on,
indicating the main refrigeration system has been
activated. In the AUTO mode, the WASH or
STANDBY functions are automatically cancelled.
The MIX REF function is automatically locked in to
maintain the mix in the cabinet and the PUMP
function is locked in to allow air/mix pump operation
as required.

In addition, for purposes of sanitizing and rinsing,
the flow rate can be increased by removing the pivot
pin and placing the restrictive bar on the top.
When drawing product, always have the restrictive
bar on the bottom.

Step 8
Remove the rear drip pan from the side panel and
take it to the sink for cleaning.

Note: To remove the o-rings, use a single service
towel to grasp the o-ring. Apply pressure in an
upward direction until the o-ring pops out of its
groove. With the other hand, push the top of the
o-ring forward. It will roll out of the groove and can
be easily removed. If there is more than one o-ring
to be removed, always remove the rear o-ring first.
This will allow the o-ring to slide over the forward
rings without falling into the open grooves.

Note: If the rear drip pan is filled with an excessive
amount of mix, refer to the Troubleshooting Guide.
Step 9
Thoroughly brush clean all disassembled parts in the
cleaning solution. Make sure all lubricant and mix
film is removed. Take particular care to brush clean
the draw valve cores in the freezer door.

Step 5
Remove the flare lines, the suction lines, the
retaining pins and the mix inlet fittings from the
pump cylinders. Remove the liquid valve bodies
from the pump cylinders.

Step 10
Place the parts on a clean, dry surface to air dry
overnight.
Step 11
Wipe clean all exterior surfaces of the freezer and
the mix cabinet.

Remove the pistons from the pump cylinders.
Remove all o-rings and check bands.

Operating Procedures

Section 7

Important: Operator Checklist
j 5. Properly prepare the cleaning and sanitizing
solutions. Read and follow the label directions
carefully. Too strong of a solution may
damage the parts and too weak of a solution
will not do an adequate job of cleaning or
sanitizing. Sanitize the freezing cylinder for 5
minutes.

During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES.

Cleaning and sanitizing schedules are governed
by federal, state, or local regulatory agencies,
and must be followed accordingly. If the unit
has a “Standby mode”, it must not be used in
lieu of proper cleaning and sanitizing
procedures and frequencies set forth by the
ruling health authority. The following check
points should be stressed during the cleaning
and sanitizing operations.

j 6. The temperature of the mix in the mix cabinet
and the walk-in cooler should be below 38_F
(3.3_C).

Regular Maintenance Checks

CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.

j 1. Replace scraper blades that are bent,
damaged or worn.

Troubleshooting Bacterial Count

j 2. Before installing the beater, be certain that the
scraper blades are properly attached over the
pins and the beater assembly is straight.

j 1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.

j 3. Check the rear shell bearing for signs of wear
(excessive mix leakage in the rear drip pan)
and be certain it is properly cleaned.

j 2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all mix passageways.

j 4. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female hex drive
socket clean and free of lubricant and mix
deposits.

j 3. Use the long white bristle brush to clean the
mix feed tube which extends from the mix
reservoir to the rear of the freezing cylinder.

j 5. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.

j 4. Use the black bristle brush to thoroughly
clean the rear shell bearing located at the rear
of the freezing cylinder. Be sure there is a
generous amount of cleaning solution on the
brush.

Important: Operator Checklist

j 6. Follow all lubricating procedures as outlined in
“Assembly”.

Model 8756

j 7. If your machine is air cooled, check the
condensers for accumulation of dirt and lint.
Dirty condensers will reduce the efficiency
and capacity of the machine. Condensers
should be cleaned monthly with a soft brush.
Never use screwdrivers or other metal probes
to clean between the fins.
Note: For machines equipped with an air
filter, it will be necessary to vacuum the filters
on a monthly schedule.

The Air/Mix Pump
j 1. Dispose of the o-rings, the check bands and
the pressure switch diaphragm if they are
worn, torn or fit too loosely. Replace them
with new ones.
j 2. Follow lubricating procedures carefully.
Never lubricate check bands.

j 8. Your machine is equipped with an auxiliary
refrigeration system. Check the auxiliary
condenser for accumulation of dirt and lint.
Dirty condensers will reduce the refrigeration
capacity of the mix cabinet. Condensers must
be cleaned monthly with a soft brush. Never
use screwdrivers or other metal probes to
clean between the fins.

j 3. Handle plastic pump parts with care to avoid
nicks and cracks.
j 4. Be sure the pressure line is securely attached
to the pressure switch.
j 5. Clean, sanitize, and lubricate the pressure
switch diaphragm daily.

j 9. On water cooled units, check the water lines
for kinks or leaks. Kinks can occur when the
machine is moved back and forth for cleaning
or maintenance purposes.

Model 8756

j 6. Be sure the air/mix pump is properly aligned
with the face plate of the motor reducer or
severe and costly damage may occur.
