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.
Note: The following procedures should be performed
by a trained service technician.
To correct the rotation on a three-phase unit,
interchange any two incoming power supply lines at
freezer main terminal block only.
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 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 splice box.
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.
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.
Use only R134a refrigerant that conforms to
the AHI standard 700 specification. The use of any
other refrigerant may expose users and operators to
unexpected safety hazards.

Section 2
To the Operator
Your freezer has been carefully engineered and
manufactured to give you dependable operation.
The user is responsible for returning the product to
the appropriate collection facility, as specified by
your local code.
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.
For additional information regarding applicable local
laws, please contact the municipal facility and/or
local distributor.
This Operator's Manual should be read before
operating or performing any maintenance on your
equipment.
Compressor Warranty Disclaimer
The refrigeration compressors 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.
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.
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.
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.
Note: Constant research results in steady
improvements; therefore, information in this
manual is subject to change without notice.
Taylor 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.
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.

Operating Procedures
The C712 machine stores mix in a hopper. It has
two 3.4 quart (3.2 liter) capacity freezing cylinders
with a three spout door.
Step 4
Apply an even coat of lubricant to the shaft. DO
NOT lubricate the hex end. (See Figure 31.)
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.
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.
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 32, “Disassembly”,
and start there.
Figure 31
Note: To ensure the mix does not leak out of the
back of the freezing cylinder, the middle section of
the boot seal should be convex or extend out from
the seal. If the middle section of the boot seal is
concave or extending into the middle of the seal,
turn the seal inside out.

MAKE SURE THE POWER SWITCH IS IN
THE “OFF” POSITION! Failure to follow this
instruction may result in severe personal injury from
hazardous moving parts.
Step 1
Before installing the beater drive shaft, lubricate the
groove on the beater drive shaft.
Step 2
Slide the beater drive shaft boot seal over the small
end of the beater drive shaft and engage into the
groove on the shaft.
Figure 32
Step 3
Heavily lubricate the inside portion of the boot seal
and also lubricate the flat end of the boot seal that
comes in contact with the rear shell bearing.
USE EXTREME CAUTION when handling
the beater assembly. The scraper blades are very
sharp and may cause injury.

Step 8
Before installing the beater assembly, check the
scraper blades for any nicks or signs of wear. If any
nicks are present, or if the blades are worn, replace
both blades.
Install the beater shoes. (See Figure 35.)
If the blades are in good condition, install the
scraper blade clips over the scraper blades. Place
the rear scraper blade over the rear holding pin on
the beater. (See Figure 33.)
Figure 35
Step 9
Slide the beater assembly the rest of the way into
the freezing cylinder.
Figure 33
Make sure the beater assembly is in position over
the drive shaft by turning the beater slightly until the
beater is properly seated. When in position, the
beater will not protrude beyond the front of the
freezing cylinder. (See Figure 36.)
Note: Scraper blades should be replaced every 3
months.
Note: The hole on the scraper blade must fit
securely over the pin to prevent costly damage.
Step 7
Holding the rear blade on the beater, slide it into the
freezing cylinder halfway. Install the front scraper
blade over the front holding pin. (See Figure 34.)

“Cleaning Procedures”.
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.
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 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 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.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
j 4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.

“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 2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all mix passageways.
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.
Note: For machines equipped with an air
filter, it will be necessary to vacuum clean the
filters on a monthly schedule.
j 4. Use the black bristle brush to thoroughly
clean the rear shell bearing located at the rear
of the freezing cylinder and the drive hub
opening in the rear wall of the mix hopper. Be
sure there is a generous amount of cleaning
solution on the brush.
Caution: Always disconnect
electrical power prior to cleaning the
condenser. Failure to follow this instruction
may result in electrocution.
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.
j 7. 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
cleaning or maintenance purposes.
Deteriorated or cracked water lines should be
replaced only by an authorized Taylor
distributor.
j 6. The temperature of mix in the mix hopper and
walk-in cooler should be below 40_F (4.4_C).

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.
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.
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. This is
extremely important. Failure to follow this
procedure may cause severe and costly damage to
the refrigeration system.
It is recommended that an authorized service
technician perform winter storage draining, to insure
all water has been removed. This will guard against
freezing and rupturing of the components.
