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.
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

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
refrigerantsarebeingadvertisedasdrop--in
replacements for numerous applications. It should be
noted that, in the event of ordinary service to this
machine’s refrigeration system, only the refrigerantspecified 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.
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.

direction until the o--ring pops out of its groove. With
the other hand, push the top of the o--ring forward until
it rolls out of the groove and can be removed easily.
Step 3
Thoroughly brush clean all disassembled parts in the
cleaning solution, making sure all lubricant and mix film
is removed. Place all the cleaned parts on a clean, dry
surfacetoairdry.
Step 4
Return to the freezer with a small amount of cleaning
solution. Brush clean the rear shell bearing at the back
of the freezing cylinder with the black bristle brush.
Brush Cleaning
Step 1
Prepare a sink with a cleaning solution (example:
Kay--5 or Stera--Sheenr). USE WARM WATER AND
FOLLOWTHEMANUFACTURER’SSPECIFICATIONS.
If another approved cleaner is used, dilute according
to label instructions. IMPORTANT: Follow the label
directions. Too STRONG of a solution can cause parts
damage, while too MILD of a solution will not provide
adequate cleaning.) Make sure all brushes provided
with the freezer are available for brush cleaning.

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.
Troubleshooting Bacterial Count:
j 1. Thoroughlycleanandsanitizemachine
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 white bristle brush to clean the mix feed
tube, which extends from the hopper down 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 to have a generous
amount of cleaning solution on the brush.
j 7. Properly prepare the 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.
j 8. Temperature of mix in mix hopper and walk--in
cooler should be below 40_F. ( 4 .4 _C.).
Regular Maintenance Checks:
j 1. Replace scraper blades that are nicked,
damaged or worn down.
j 2. Before installing beater, be certain the scraper
blade is properly attached.
j 3. Check rear shell bearing for signs of wear
(excessive mix leakage in 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 square 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 5. IF LOCAL HEALTH CODES PERMIT THE
USE OF RERUN, make sure the mix rerun is
stored in a sanitized, covered stainless steel
container, placed in the walk--in cooler and used
the following day. DO NOT prime the machine
with rerun. When using rerun, skim off the foam
and discard, then mix t he rerun with f resh mix
in a ratio of 50/50 during the day’s operation.
j 6. On a designated day of the week, run the mix as
low as feasible and discard after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform counts.
Model C902Important: Operator Checklist
j 6. Follow all lubricating procedures as outlined in
“Assembly”.
j 7. Check the condenser(s) for accumulation of dirt
and lint. Dirty condensers will reduce the
efficiency andcapacity ofthe 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,
vacuum clean the filters on a monthly schedule.

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 to be left unheated and subject to freezing
conditions.
Disconnect the freezer from the main power source to
prevent possible electrical damage. Wrap detachable
parts of the freezer such as beater, blades, drive shaft,
and freezer door, and place in a protected dry place.
Rubber trim parts and gaskets can be protected by
wrapping with moisture--proof paper. All parts should
be thoroughly cleaned of dried mix or lubrication
accumulations which attract mice and other vermin.
Your local Taylor Distributor can perform this service
for you.
