Air Cooled Units
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.
Air cooled units require a minimum of 3” (76 mm) of
air space on both sides, 3” (76 mm) at the rear, and
12” (305 mm) on the top of the unit. Minimum air
clearances must be met to assure adequate air flow
for optimum performance.
Water Cooled Refrigeration Units
(Water Cooled Units Only)
Note: Water lines beyond 200 ft. (61 m) require 1/2”
(13 mm) water lines.
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.
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.
Depending on local water conditions, it may be
advisable to install a water strainer to prevent
foreign substances from clogging the automatic
water valve.
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.
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, and
third, through the outlet fitting located at the top of
the condenser to an open trap drain.
IMPORTANT: Water pressures are pre-set at the
factory. Do not adjust the water pressure.
Improper water adjustments may cause operation
discrepancies.

Initial Freezing Cylinder Cleaning
Due to the types of products used in FCB
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.
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. Sanitize, using the sanitizing
procedures outlined in this Operator Manual, starting
on page 24.
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.
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.
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.
NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.

engineered and manufactured to give you
dependable operation.
unsorted municipal waste. The user is responsible
for returning the product to the appropriate collection
facility, as specified by your local code.
The Model C302, 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.
For additional information regarding applicable local
laws, please contact the municipal facility and/or
local distributor.
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 finding their way
into the service industry.
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.
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.
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.
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.
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
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.

Operating Procedures
The Model C302 contains four 7 quart (6.6 liter)
freezing cylinders.
Assembly
MAKE SURE THE CONTROL SWITCHES
ARE IN THE “OFF” POSITION. Failure to do so
may result in personal injury or component
damage.
CAUTION: This unit is pressurized
when in operation. The control switches must be in
the OFF position until the unit is completely
assembled. No part should ever be removed from
the machine while it is in operation. No parts should
be removed until the control switch has been turned
to the OFF position and all pressure has been
relieved by opening the draw valves. Failure to
follow this instruction may result in severe personal
injury from hazardous moving parts or from the
impact of propelled parts.
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube HP).
Step 1
Before installing the beater drive shaft, lubricate the
o-ring groove. Slide the o-ring into the groove on the
drive shaft. Lubricate the drive shaft seal groove, the
o-ring, and the shaft portion that comes in contact
with the bearing on the beater drive shaft. DO NOT
lubricate the hex end of the drive shaft.
The syrup flow control combines the two ingredients
of carbonated water and syrup, and sends this
combination to the freezing cylinder. As product is
drawn, new product will flow from the flow control
into the freezing cylinder.
We begin our instructions at the point where the
parts are disassembled and laid out to air dry.
The following procedures will show you how to
assemble the parts into the freezer, sanitize them,
and prime the freezer with fresh product.
Duplicate the following procedures, where they
apply, for the other freezing cylinders.
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 31, “Disassembly”
and start there.

Step 4
Lubricate the inside diameter of the drive shaft seal.
Install the drive shaft seal bushing in the drive shaft
seal.
Insert the beater 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.
Be certain the drive shaft fits into the drive coupling
without binding.
IMPORTANT: Remove any excess lubricant from
the seal.
Figure 7
Note: The drive shaft bushing must be positioned in
the center of the drive shaft seal.
Figure 9
Step 5
Before installing the beater assembly, check the
scraper blades for any nicks or signs of wear. If any
nicks are present or if the blade is worn, replace
both blades. If the blades are in good condition,
place the scraper blades over the holding pins on
the beater.
Step 3
Slide the seal and bushing over the shaft and groove
until it snaps into place. Fill the inside portion of the
seal with more lubricant and evenly lubricate the end
of the seal that fits onto the rear shell bearing.
Note: Each hole on the scraper blade must fit
securely over each pin.

locating pin is in position in the locating hole of the
drive shaft. Turn the beater slightly to be certain that
the beater is properly seated. When in position, the
beater will be approximately 3/8” inside the front of
the freezing cylinder.
Before installing the draw valve, slide the two o-rings
into the grooves on the draw valve. Lubricate the
o-rings and the valve as illustrated below.
Important: Failure to properly seat the beater may
cause damage to the beater and the door.

Slowly move the syrup sampling valve to the fully
open position by turning the handle “down” toward
the sampling line. Allow the liquid to run into a pail
until all the sanitizer is removed and full strength
product is flowing.
Step 8
Stir the finished product. Pour a small amount of
product over the refractometer. The brix reading
should register 13 to 14. A reading higher than this
would cause a darker, richer product. The
refrigeration system would have to run longer to
freeze this excess syrup. A reading lower than this
could cause a freeze-up in the freezing cylinder
because of the excess water.
Figure 35
Brix is the ratio of syrup to water which will directly
affect the quality and taste of the product. Brixing
should be done before priming the freezer and when
a change in syrup flavor has been made.

Step 9
Note: The position of the handle on the syrup
sampling valve determines the direction of product
flow. The down position opens the syrup sampling
valve for collecting brix samples. The center position
shuts off the product flow. The up position directs
the flow of product to the freezing cylinder.
To adjust the brix, turn the adjustment screw located
behind the drip tray shelf. Clockwise adjustments
increase the amount of syrup to water, and
counterclockwise adjustments decrease the amount
of syrup to water. Adjust the screw in small
increments and check the brix again.
Step 11
Place a pail beneath the door spout. Open the draw
valve and drain the freezing cylinder to remove any
incorrectly brixed product. Close the draw valve.
Step 12
Press the PRIME (+ + +) key. Allow the liquid level
to fill to the prime plug hole.

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.
Wrap detachable parts of the freezer such as the
beater, the scraper blades, the drive shaft, and the
freezer door. Place these parts 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.
Your local Taylor Distributor can perform this service
for you.
Note: 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.
