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 opentrapdrain.
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.
Each unit requires one power supply for each data

Page 7
SSupply 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.
Beater Rotation
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Refrigerant
In consideration of our environment, Taylor
proudly uses only earth friendly 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).
However, any gas under pressure is potentially
hazardous and must be handled with caution.
NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.
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.
The following procedures must be
performed by an authorized Taylor service
technician.
To correct the rotation on a three-phase unit,
interchange any two incoming power supply lines at
freezer main terminal block only.
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.
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.
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.

Section 2To the Operator
Your freezer has been carefully engineered and
manufactured to give you dependable operation.
This unit, when properly operated and cared for, will
produce a consistent quality product. Like all
mechanical products, it will require cleaning and
maintenance. A minimum amount of care and
attention is necessary if the operating procedures
outlined in this manual are followed closely.
This Operator's Manual should be read before
operating or performing any maintenance on your
equipment.
Your freezer will NOT eventually compensate and
correct for any errors made during the set-up or
filling operations. Thus, the initial assembly and
priming procedures are of extreme importance. It is
strongly recommended that all personnel
responsible for the equipment's operation study
these procedures together in order to be properly
trained and to make sure that no misunderstandings
exist.
In the event you should require technical assistance,
please contact your local authorized Taylor
Distributor.
Note: Warranty is valid only if the parts are
authorized Taylor parts, purchased from an
authorized Taylor Distributor, and the required
service work is provided by an authorized Taylor
service technician. Taylor reserves the right to deny
warranty claims on equipment or parts if
non-approved parts or refrigerant were installed in
the machine, system modifications were performed
beyond factory recommendations, or it is determined
that the failure was caused by neglect or abuse.
Note: Constant research results in steady
improvements; therefore, information in this
manual is subject to change without notice.
If the crossed out wheeled bin symbol is
affixed to this product, it signifies that this product is
compliant with the EU Directive as well as other
similar legislation in effect after August 13, 2005.
Therefore, it must be collected separately after its
use is completed, and cannot be disposed as
unsorted municipal waste.
The user is responsible for returning the product to

Compressor Warranty Disclaimer
The refrigeration compressor(s) on this machine are
warranted for the term indicated on the warranty
card accompanying this machine. 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
machine's refrigeration system, only the refrigerant
specified on the affixed data label should be
used. The unauthorized use of alternate refrigerants
will void your compressor warranty. It will be the
owner's responsibility to make this fact known to any
technician he employs.
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 machine, Taylor has no obligation to
either supply or provide its replacement either at
billable or unbillable terms. Taylor does have the
obligation to recommend a suitable replacement if
the original refrigerant is banned, obsoleted, or no
longer available during the five year warranty of the
compressor.
The Taylor Company will continue to monitor the
refrigerant industry and test new alternates as they
are being developed. Should a new alternate prove,
through our testing, that it would be accepted as a
drop-in replacement, then the above disclaimer
would become null and void. To find out the current
status of an alternate refrigerant as it relates to your
compressor warranty, call the local Taylor Distributor
or the Taylor Factory. Be prepared to provide the
Model/Serial Number of the unit in question.

Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(examples: Kay-5R or Stera-SheenR). USE
WARM WATER AND FOLLOW THE
MANUFACTURER'S SPECIFICATIONS.
If an approved cleaner other than Kay-5r or
Sterar-Sheen is used, dilute it according to the label
instructions. IMPORTANT: Follow the label
directions. Too STRONG of a solution can cause
parts damage and too MILD of a solution will not
provide adequate cleaning. Make sure all brushes
provided with the freezer are available for brush
cleaning.
Step 2
Remove the seals from the drive shafts.
Step 3
Remove the scraper blade clips from the scraper
blades.
Step 4
From the freezer doors, remove the gaskets, front
bearings, pivot pins, draw handles, draw valves,
prime plugs, and design caps. Remove all o-rings.
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.
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.
Remove the pistons from the pump cylinders.
Remove all o-rings and check bands.
Step 6
Return to the freezer with a small amount of
cleaning solution. Use the black bristle brush to
brush clean the rear shell bearings at the back of the
freezing cylinders.
Figure 69
Step 7
Using the long, flexible brush and cleaning solution,
clean the mix inlet tubes located in the mix cabinet.
Thoroughly clean the tubes all the way up to the
freezing cylinder. This area needs special attention
because bacteria and milkstone can build up here.
Step 8
Remove the rear drip pan from the side panel and
take it to the sink for cleaning.
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 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.

Section 7Important: Operator Checklist
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.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
Troubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
j 2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all mix passageways.
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 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.
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.
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
j 1. Replace scraper blades that are bent,
damaged or worn.
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 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 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 5. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j 6. Follow all lubricating procedures as outlined in
“Assembly”.
34
Model 8756Important: Operator Checklist
Page 39
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.
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 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.
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 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 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.
