Section 1
To the Installer
This machine is designed for indoor use only.
Electrical Connections
Each freezer requires one power supply for each data
label. Check the data label(s) on the freezer for fuse,
circuit ampacity and electrical specifications. Refer to
the wiring diagram provided inside of the electrical box,
for proper power connections.
DO NOT install the machine in an area where
a water jet could be used to clean or rinse the machine.
Failure to follow this instruction may result in serious
electrical shock.
In the United States, this equipment is intended to be
installed in accordance with the National Electrical
Code (NEC), ANSI/NFPA 70--1987. The 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. Compliance therewith and
proper maintenance will result in an installation
essentially free from hazard!
Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut-off valve. On the underside rear 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.
In all other areas of the world, equipment should be
installed in accordance with the existing local codes.
Please contact your local authorities.
Stationary appliances which are not equipped with a
power cord and a plug or other 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.
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
Beater rotation must be clockwise as viewed looking
into the freezing cylinder of any model freezer.
Note: The following procedures should be
performed by a trained service technician.
Air Cooled Units
To correct rotation on a three-phase unit, interchange
any two incoming power supply lines at freezer main
terminal block only.
The model 750 air cooled unit requires a minimum of
6” (152 mm) of clearance on both sides and 0” in the
rear of the unit. The model 751, 754, 774 and 794 units
require 3” on all sides. This will allow for adequate air
flow across the condenser(s). Failure to allow
adequate clearance can reduce the refrigeration
capacity of the freezer and possibly cause permanent
damage to the compressor.
To correct rotation on a single-phase unit, change the
leads inside the beater motor. (Follow diagram printed
on motor.)
Electrical connections are made directly to the
terminal block provided in the main control box located
under the upper left side panel on the Model 750, or

Section 2
To the Operator
The freezer you have purchased has been carefully
engineered and manufactured to give you dependable
operation. The Taylor Company soft-serve models
covered in this manual consist of the following: 750,
751, 754, 774, and 794.
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.
These units, when properly operated and cared for, will
produce
a
consistent quality product. Like all
mechanical products, they 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 Taylor freezer will NOT eventually compensate
for and correct any errors during the set-up or filling
operations. Thus, the initial assembly and priming
procedures are of extreme importance. It is strongly
recommended that personnel responsible for the
equipment’s operation, both assembly and
disassembly, go through these procedures together in
order to be properly trained and to make sure that no
confusion exists.
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.
In the event you should require technical assistance,
please contact your local authorized Taylor Distributor.
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 Taylor Company will continue to monitor the
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.
The user is responsible for returning the product to the
appropriate collection facility, as specified by your local
code.
For additional information regarding applicable local
laws, please contact the municipal facility and/or local
distributor.

The following chart identifies the symbol definitions.
STANDBY Key
The Separate Hopper Refrigeration System (SHR)
and the Cylinder Temperature Retention System
(CTR) are standard features on these machines. The
SHR incorporates the use of a separate small
refrigeration system to maintain the mix in the hopper
below 40_(4.4_C) to assure bacteria control. The CTR
works with the SHR to maintain a good quality product.
During long “No Sale” periods, it is necessary to warm
the product in the freezing cylinder to approximately
35_F to 40_F (1.7_C to 4.4_C) to prevent overbeating
and product breakdown.
= OFF
= ON
= MIX
= STANDBY
= WASH
= AUTO
To activate the SHR and CTR, press the STANDBY
key. Remove the air orifice and place the air tube (end
without the hole) into the mix inlet hole.
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 and AUTO functions are
automatically cancelled. The MIX REF function is
automatically locked in to maintain the mix in the
hopper.
Power Switch
When placed in the ON position, the power switch
allows SOFTECH control panel operation.
To resume normal operation, press the AUTO key.
When the unit cycles off, the product in the freezing
cylinder will be at serving viscosity. At this time, place
the air tube (end with the hole) into the mix inlet hole
and install the air orifice.
MIX LOW Indicator Light
Located on the front of the machine is a mix level
indicating light. When the light is flashing, it indicates
that the mix hopper has a low supply of mix and should
be refilled as soon as possible. Always maintain at
least 3” (7.6 cm) of mix in the hopper. If you neglect to
add mix, a freeze-up may occur. This will cause
eventual damage to the beater, blades, drive shaft,
and freezer door.
WASH Key
When the WASH key is pressed, the light comes on.
This indicates beater motor operation. The STANDBY
or AUTO modes must be cancelled first to activate the
WASH mode.
AUTO Key
When the AUTO key is pressed, the light comes on.
This indicates that 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 mix hopper.
MIX REF Key
When the MIX REF key is pressed, the light comes on
indicating the mix hopper refrigeration system is
operating. For the Models 754, 774, and 794 the MIX
REF is controlled by the left side of the freezer as
viewed from the operator end. The MIX REF function
cannot be cancelled unless the AUTO or STANDBY
modes are cancelled first.
Note: An indicating light and an audible tone will
sound whenever a mode of operation has been
pressed. To cancel any function, press the key again.
The light and mode of operation will shut off.

draw handle is raised, new mix and air from the
hopper will flow down into the freezing cylinder.
This will keep the freezing cylinder properly
loaded and will maintain overrun.
Reset Button
On counter models, the reset button is located on the
side of the unit. On console models, the reset button
is located in the service panel. The reset protects the
beater motor from an overload condition. If anoverload
occurs, 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.
2. During long “No Sale” periods, remove the air
orifice. Lubricate the o-rings on the air tube (the
end without the hole), and place it into the
mix inlet hole. This will prevent any mix from
entering the freezing cylinder.
The air orifice is used to meter a certain amount
of air into the freezing cylinder. The air orifice
maintains overrun and allows enough mix to enter
the freezing cylinder after a draw.
Do not use metal objects to press the reset
button. Failure to follow this instruction may
result in electrocution.
Turn the power switch to the ON position. Press the
WASH key and observe the freezer’s performance.
Open the side access panel. Make sure the beater
motor is turning the drive shaft in a clockwise direction
(from the operator end) without binding.
Adjustable Draw Handle
If the beater motor is turning properly, press the WASH
key to cancel the cycle. Press the AUTO key to resume
normal operation. If the freezer shuts down again,
contact a service technician. (For Models 754, 774,
and 794 press the AUTO key on both sides of the unit
to resume normal operation.)
These units feature an adjustable draw handle to
provide the best portion control. The draw handle
should be adjusted to provide a flow rate of 5 to 7-1/2
oz. (148 to 222 ml) of product per 10 seconds. To
INCREASE the flow rate, turn the screw
COUNTERCLOCKWISE.
Turn
the
screw
CLOCKWISE to DECREASE the flow rate. During
“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 place the restrictive bar on the bottom.
Air Tube
The air tube serves two purposes. One end of the tube
has a hole and the other end does not.

Section 6
Operating Procedures
The Model 751 has been selected to illustrate the
step-by-step operating procedures for all models
contained in this manual. These models, for all
practical purposes of operation, are the same.
Step 3
Prepare a pail of an approved 100 PPM sanitizing solu-
tion (example: Kay-5r). USE WARM WATER AND
FOLLOW THE MANUFACTURER’S SPECIFI-
CATIONS. Sanitize the topping pumps by placing the
entire pump assembly in the pail of sanitizing solution.
Pump the solution through the assembly to thoroughly
sanitize the pump.
Each unit stores mix in a hopper. The mix then flows
by gravity through an air tube down into the freezing
cylinder. They all have 3.4 quart (3.2 liter) capacity
freezing cylinders. The Models 750, 751, 754, and 774
have 20 quart (18.9 liter) mix hoppers. The Model 794
has 14 quart (13.2 liter) mix hoppers.
Step 4
Remove the two topping pumps. Fill each stainless
syrup jar with topping. Replace the topping pumps in
the syrup jars.
Duplicate the following procedures, where they apply,
for the second freezing cylinder on Models 754, 774,
and 794.
Assembly
We begin our instructions at the point where we enter
the store in the morning and find the parts
disassembled and laid out to air dry from the previous
night’s cleaning.
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
These opening procedures will show you how to
assemble these parts into the freezer, sanitize them,
and prime the freezer with fresh mix in preparation to
serve your first portion.
MAKE SURE POWER SWITCH IS IN THE
“OFF” POSITION! Failure to follow this instruction
may result in severe personal injury from hazardous
moving parts.
If you are disassembling the machine for the first time
or need information to get to this starting point in our
instructions, turn to page 24, “Disassembly”, and start
there.
Step 1
Install the drive shaft. Lubricate the groove and shaft
portion that comes in contact with the bearing on the
beater drive shaft. Slide the seal over the shaft and
groove until it snaps into place. DO NOT lubricate the
hex end of the drive shaft. Fill the inside portion of the
seal with 1/4” more lubricant and lubricate the flat side
of the seal that fits onto the rear shell bearing.
Prior to Set-Up (Model 774)
Step 1
Remove the two stainless syrup jars with topping
pumps from the syrup rail. Check the water level in the
heated syrup topping well. Make sure the water is filled
to the indicating mark on the bottom of the well. The
heated rail should have 32 oz. (946.2 ml) of water.
Step 2
Place the heater switch in the ON position.
Note: This heating process will take approximately
2-1/2 hours to reach temperature. The water level in
the topping wells must be checked at least once daily.

Insert the drive shaft into the freezing cylinder, hex end
first, and into the rear shell bearing until the seal fits
securely over the rear shell bearing. Engage the hex
end firmly into the drive coupling. Be sure the drive
shaft fits into the drive coupling without binding.
Figure 6
Slide the beater the remainder of the way into the
freezing cylinder and over the end of the drive shaft.
The beater should fit snugly, but not so tightly that the
beater cannot be turned slightly to engage the drive
shaft. If the beater slides in too easily with little or no
resistance, there will not be enough force against the
beater to hold the blades in place. If this is the case,
contact your authorized Taylor service technician.

Remove the handscrews, freezer door(s), beater(s),
scraper blades, and drive shaft(s) from the freezing
cylinder(s). Take these parts to the sink for cleaning.
Step 2
Remove the front drip tray and the splash shield.
Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution (ex-
ample: Kay-5r). USE WARM WATER AND FOLLOW
THE MANUFACTURER’S SPECIFICATIONS. If
another approved cleaner is used, dilute it according
to the label instructions. (IMPORTANT: Follow the
label directions. Too STRONG of a solution can cause
parts damage, while too MILD of a solution will not pro-
vide adequate cleaning.) Make sure all brushes pro-
vided with the freezer are available for brush cleaning.

j 7. Properly prepare the cleaning and sanitizing
During Cleaning and Sanitizing
solutions. Read and follow 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.
Cleaning and sanitizing schedules are governed by
your State or local regulatory agencies and must be
followed accordingly. The following check points
should be stressed during the cleaning and sanitizing
operations.
j 8. The temperature of the mix in the mix hopper
and walk-in cooler should be below 40_F.
(4.4_C.).
WE RECOMMEND DAILY CLEANING AND
SANITIZING.
ALWAYS FOLLOW LOCAL HEALTH CODES.
Regular Maintenance Checks
j 1. Replace scraper blades that are nicked or
damaged. Before installing the beater
assembly, be certain that scraper blades are
properly attached to the helix.
Troubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize machine
regularly, including complete disassembly and
brush cleaning.
j 2. Check the rear shell bearing for signs of wear
(excessive mix leakage in 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 3. 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 white bristle brush to clean the mix inlet
hole which extends from the mix hopper down
to the rear of the freezing cylinder.
j 4. 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 to have a generous
amount of cleaning solution on the brush.
j 5. Follow all lubricating procedures as outlined in
“Assembly”.
j 6. 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.
j 5. IF LOCAL HEALTH CODES PERMIT THE
USE OF RERUN, make sure the mix rerun is
stored in a sanitized, covered stainless steel
container and used the following day. DO NOT
prime the machine with rerun. When using
rerun, skim off the foam and discard. Mix the
rerun with fresh mix in a ratio of 50/50 during the
days operation.
j 6. On a designated day of the week, run the mix as
low as feasible and discard it after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform counts.
Caution:
Always
disconnect
electrical power prior to cleaning the
condenser. Failure to follow this instruction
may result in electrocution.

j 7. If 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 hopper. Condensers must
be cleaned monthly with a soft brush. Never use
screwdrivers or other metal probes to clean
between the fins. Failure to follow this
instruction may result in electrocution.
Winter Storage
If the place of business is to be closed during the winter
months, it is important to protect the freezer by
following certain precautions, particularly if the
building is subject to freezing conditions.
Disconnect the freezer from the main power source to
prevent possible electrical damage.
On water cooled freezers, disconnect the water
supply. Relieve pressure on the spring in the water
valve. Use air pressure on the outlet side to blow out
any water remaining in the condenser, and then add a
liberal amount of permanent type auto anti-freeze.
This is extremely important. Failure to follow this
procedure may cause severe and costly damage tothe
refrigeration system.
Caution:
Always
disconnect
electrical power prior to cleaning the
condenser. Failure to follow this instruction
may result in electrocution.
j 8. If your machine is water cooled, check the water
lines for kinks or leaks. Kinks can occur when
the machine is moved back and forth for
Your local Taylor Distributor can perform this winter
storage service for you.
Wrap detachable parts of the freezer such as beater,
blades, drive shaft, and freezer door, and place them
in a protected dry place. Rubber trim parts and gaskets
can be protected by wrapping them with
moisture-proof paper. All parts should be thoroughly
cleaned of dried mix or lubrication which attract mice
and other vermin.
