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 m m )
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.
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.
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 ) male flare 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.

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.

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.

Section 6Operating Procedures
The Model C302 contains four 7 quart (6.6 liter)
freezing cylinders.
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.
Assembly
Slide the seal over the shaft and groove until it
snaps into place. Pinch the boot seal and fill the
inside portion of the seal with 1/4” more lubricant.
Figure 6
Step 2
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. Be
certain the drive shaft fits into the drive coupling
without binding.
MAKE SURE THE CONTROL SWITCHES
ARE IN THE “OFF” POSITION. Failure to do so
may result in personal injury or component
damage.
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube HP).
Step 1
Slide the o-ring into the first groove on the drive
shaft. Lubricate the groove, o-ring, the area where
the boot seal snaps onto the drive shaft, 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.

Step 3
Check the scraper blade for any nicks or signs of
wear. If any nicks are present, replace the blade. If
the blade is in good condition, place the clip over the
blade. Place the rear scraper blade and clip over the
single holding pin on the beater (knife edge to the
outside). Holding the blade on the beater, turn it over
and install the front blade the same way.
Figure 8
Step 4
Holding the blades in position, insert the beater
assembly into the freezing cylinder and slide it into
position over the drive shaft. Turn the beater slightly
to be certain that the beater is properly seated.
When in position, the beater will not protrude beyond
the front of the freezing cylinder.
Step 5
Install the white, plastic guide bearing on the short
end of the baffle assembly. Slide the o-ring into the
groove on the long end of the baffle assembly and
lubricate the o-ring. Do not lubricate the guide
bearing.

Sanitizing
IMPORTANT: If a unit is sanitized, and will not be
used for an extended period of time, clean water
should be used to flush all sanitizer from the lines.
Remove the water from all the lines and components
prior to storage of the unit. Upon return to service,
the unit must be sanitized prior to use.
Note: The following instructions are for one side of
the unit. Each side consists of two freezing cylinders
each, identified on the corresponding LCD as “left”
(L) and “right” (R).
Step 1
Open the lighted display door. Place the control
switch in the ON position.
Step 3
Using an empty bag of syrup, cut the syrup line
connector from the end of the bag.

the sampling line. Allow the liquid to run into a pail
until all the sanitizer is removed and full strength
product is flowing.
Figure 29
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 7
Pour the product from the syrup sampling valve into
a cup. Close the syrup sampling valve by turning the
handle to the center position.
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 31
Step 9
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.
Figure 32
Repeat this step until a correct brix reading is
Figure 30
Model C302 NPROperating Procedures
registered.
27
Page 32
Step 10
Once the proper brix has been achieved, turn the
handle “up” to allow product to flow to the mix tank.
Figure 33
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.
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 14
To place the freezing cylinders in the AUTO mode,
press the AUTO (- ->) key for each f r eez ing cylinder.

Prepare a sink or a pail with an approved cleaning
solution. USE WARM WATER AND FOLLOW THE
MANUFACTURER'S SPECIFICATIONS (examples:
Kay-5® or Stera-Sheen®).
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.
Step 2
Return to the freezer with a small amount of
cleaning solution. With a single service towel, wipe
clean the rear shell bearing surface. Brush-clean the
rear shell bearings at the back of the freezing
cylinders with the black bristle brush.
Step 3
Remove the:
Sseals and o-rings from the drive shafts
Scaps, pins, and springs from freezer doors
Sdraw valve handles from freezer doors
Sdraw valves from freezer doors
So-rings from draw valves
Sprime plugs from freezer doors
So-rings from prime plugs
Sgaskets and front bearings from freezer
doors
Sbaffle assembly, baffle arm, guide bearing,
and o-ring

Section 7Important: Operator Checklist
During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES.
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.
WE RECOMMEND CLEANING AND SANITIZING
EVERY 120 DAYS.
Troubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
j 2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all product passageways.
j 3. Use the black bristle brush to thoroughly
clean the rear shell bearing located at the rear
of the freezing cylinder. Be sure there is a
generous amount of cleaning solution on the
brush.
j 4. Using a screwdriver and a cloth towel, keep
the rear shell bearing and the female hex
drive socket clean and free of lubricant and
product deposits.
j 6. Clean and sanitize the syrup lines regularly to
prevent syrup residue build-up that would
restrict the proper flow of syrup.
j 7. On a regular basis, take a brix reading to
assure a consistent quality product.
Regular Maintenance Checks
j 1. Replace scraper blades that are nicked,
damaged or worn down.
j 2. Before installing the beater, be certain that the
scraper blades are properly attached over the
pins.
j 3. Check the rear shell bearing for signs of wear
(excessive product leakage from the rear drip
pans to the front drip tray).
j 4. Dispose of o-rings or seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j 5. Follow all lubricating procedures as outlined in
“Assembly”.
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.
080926
j 6. Check the condenser for an accumulation of
dirt and lint. A dirty condenser will reduce the
efficiency and capacity of the machine. The
condenser should be cleaned monthly by
removing the poly-flo filter and cleaning it.

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.
Your local Taylor Distributor can perform this service
for you.
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.
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.
