Section 1
To the Installer
The Model C300NP is designed for indoor use only.
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. 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.
DO NOT install the machine in an area
where a water jet could be used. Failure to follow
this instruction may result in serious electrical shock.
Air Cooled Units
Air cooled units require a minimum of 3” (76 mm) of
air space on the rear and left side to the top of the
unit, 0” on the right side, and 12” (305 mm) to the
ceiling. 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).
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.
Water Cooled Refrigeration Units
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.
(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.
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.
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 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.

Each unit requires one power supply for each data
label on the unit. Check the data label(s) on the
freezer for branch circuit overcurrent protection or
fuse, circuit ampacity, and other electrical
specifications. Refer to the wiring diagram provided
inside of the control box for proper power
connections.
Beater rotation must be clockwise as viewed looking
into the freezing cylinder.
In the United States, this equipment is intended to
be installed in accordance with the National
Electrical Code (NEC), ANSI/NFPA 70-1987. The
purpose of the NEC code is the practical
safeguarding of persons and property from hazards
arising from the use of electricity. This code contains
provisions considered necessary for safety.
Compliance therewith and proper maintenance will
result in an installation essentially free from hazard!
In all other areas of the world, equipment should be
installed in accordance with the existing local codes.
Please contact your local authorities.
Figure 2
The following procedures should be performed by a
trained service technician:
Stationary appliances which are not equipped with a
power cord and a plug or other device to disconnect
the appliance from the power source must have an
all-pole disconnecting device with a contact gap of at
least 3 mm installed in the external installation.
To correct rotation on a single-phase unit, change
the leads inside the beater motor. Follow the
diagram printed on the motor. (Note: Three-phase
units have single-phase motors.)

Section 2
To the Operator
The freezer you have purchased 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.
For additional information regarding applicable local
laws, please contact the municipal facility and/or
local distributor.
The Model C300NP, 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.
Compressor Warranty Disclaimer
This Operator's Manual should be read before
operating or performing any maintenance on your
equipment.
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.
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.
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.
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.
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.

The Liquid Crystal Display (LCD) is located on the
front control panel. The LCD is used to show the
current operating mode of the freezing cylinders.
The LCD also indicates whether there is enough
syrup, CO2, and water being supplied to the freezer.
If an error in the machine operation occurs, a
warning tone will sound and the word “FAULT” will
flash on the third line of the display.
Line 2 indicates the status of the syrup systems in
each freezing cylinder. As long as syrup is available,
the word “OK” will appear on the LCD. When the
syrup supply is insufficient, the word “OUT” will flash
on the LCD. The same rules apply to the fourth line
which indicates the status of the CO2 and the H2O.
The third line of this display is a fault indicator. If an
error in machine operation occurs, the word

Operating Procedures
The Model C300NP contains two 7 quart (6.6 liter)
freezing cylinders.
The syrup flow control combines the two ingredients
of 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. CO2 is supplied after the flow
control to carbonate the product and aid in
dispensing.
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 cylinder.
Figure 7
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 27 , “Disassembly”
and start there.
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.

Step 7
Step 9
Pour the product from the syrup sampling valve into
a cup. Close the syrup sampling valve by turning the
handle to the center position.
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 31
Figure 33
Repeat this step until a correct brix reading is
registered.
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.
Step 10
Once the proper brix has been achieved, turn the
handle “up” to allow product to flow to the mix tank.
Figure 34
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 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.
Discard all o-rings and replace them with new ones.
Note: To remove o-rings, use a single service towel
to grasp the o-ring. Apply pressure in an upward
direction until the o-ring pops out of its groove. With
the other hand, push the top of the o-ring forward. It
will roll out of the groove and can be easily removed.
If there is more than one o-ring to be removed,
always remove the rear o-ring first. This will allow
the o-ring to slide over the forward rings without
falling into the open grooves.

damaged or worn down.
j 1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
j 2. Before installing the beater, be certain that the
scraper blades are properly attached over the
pins.
j 2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all product passageways.
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 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. Dispose of o-rings or seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
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 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.
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.
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.
