Site Preparation

Review the area where the unit will be installed
before uncrating the unit. Make sure that all possible
hazards to the user and the equipment have been
addressed.

Air Cooled Units

Air cooled units require a minimum of 3” (76 mm) of
air space on one side, 3” (76 mm) at the rear, and
12” (305 mm) on the top of the unit. This is required
to allow for adequate air flow through the
condenser(s). Failure to allow adequate clearance
can reduce the refrigeration capacity of the freezer
and possibly cause permanent damage to the
compressor(s).

For Indoor Use Only: This unit is designed to operate
indoors, under normal ambient temperatures of
70_-75_F(21_-24_C). The freezer has successfully
performed in high ambient temperatures of
104_(40_C) at reduced capacities.

This unit must NOT be installed in an area
where a water jet or hose can be used. NEVER use a
water jet or hose to rinse or clean the unit. Failure to
follow this instruction may result in electrocution.

This unit must be installed on a level surface
to avoid the hazard of tipping. Extreme care should be
taken in moving this equipment for any reason. Two or
more persons are required to safely move this unit.
Failure to comply may result in personal injury or
equipment damage.

Water Cooled Refrigeration Units
(Water Cooled Units Only)

On the back of the unit, two additional 3/8” (9.5 mm)
F.P.T. water connections for condenser inlet and
outlet have been provided for easy hook--up. 3/8”
(9.5 mm) inside diameter water lines should be
connected to the machine. Flexible lines are
recommended if local codes permit. Failure to use
adequate size water lines may cause the unit to go
on high head pressure and shut down.

Depending on local water conditions, it may be
advisable to install a water strainer to prevent
foreign substances from clogging the automatic
water valve.

DO NOT INSTALL A HAND SHUT--OFF VALVE ON
THE “OUT” LINE! Water cooled units are counter
flow and the water should flow in this order: First
through the automatic water valve. Second, through
the inlet located at the bottom of the condenser.
Third, through the outlet fitting located at the top of
the condenser toanopentrapdrain.

IMPORTANT: Water pressures are pre--set at the
factory. Do not adjust the water pressure.
Improper water adjustments may cause operation
discrepancies.

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.

Water Connections

An adequate cold water supply must be provided
with a hand shut--off valve. On the back of the unit, a
3/8” (9.5 mm) M.F.L. water connection has been
provided for easy hook--up. A flexible line is
recommended, if local codes permit. A minimum of
25 psi water pressure is required to avoid having the
unit cut out the low water pressure switch. A booster
pump must be provided if this pressure is not
available.

Note: Water lines beyond 200 ft. (61 m) require 1/2”
(13 mm) water lines.

INSTALL POTABLE WATER CONNECTION
WITH ADEQUATE BACK-FLOW
PROTECTION TO COMPLY WITH
APPLICABLE NATIONAL, STATE AND
LOCAL CODES.

It is always a good practice to have a filter system to
improve the quality of the water and to avoid
clogging the operating components.

IMPORTANT: The water filter (064422--SER) must
be thoroughly flushed with water before connecting it
to the machine. This removes any loose particles
present from the manufacture of the filter that could
clog the flow control. To flush the filter, connect the
inlet end of the filter to the water supply. Position the
outlet end of the filter over an empty pail. Open the
water supply. Allow water to flow through the filter
until the water exiting the filter is clear. Close the
water supply. Attach the outlet end of the filter to the
machine. Reopen the water supply.

Initial Freezing Cylinder Cleaning

Due to the types of products used in FCB
equipment, it is imperative that the freezing cylinder
and the inlet tube be thoroughly brush cleaned,
rinsed, and sanitized before running any product.

Prepare a cleaning solution, using 2 oz. of liquid
detergent in 2 gallons of warm water. Using this
solution, brush clean the freezing cylinder and the
inlet tube. Rinse the freezing cylinder and the inlet
tube with clean water and then sanitize, using the
sanitizing procedures outlined in this Operator
Manual, starting on page 23.

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
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 2 To the Operator

The freezer you have purchased has been carefully
engineered and manufactured to give you
dependable operation.

The Model C300, when properly operated and cared
for, will produce a consistent quality product. Like all
mechanical products, this machine will require
cleaning and scheduled 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 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 for service.

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
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.

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.

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.
