Section 1 To the Installer
The Model C300NP is designed for indoor use only.
DO NOT installthemachineinanarea
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).
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.
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.
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.

diagram provided inside of the control box, for
proper power connections.
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.
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.
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
Beater rotation must be clockwise as viewed looking
into the freezing cylinder.
Figure 2
The following procedures should be performed by a
trained service technician:
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 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.
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.
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.

Syrup Out Indicator
AUTO MODE AUTO
OUT SYRUP OK
CO2-OK WATER-OK
If the word “OUT” appears in one of the columns
next to the word “SYRUP”, it indicates a lack of
syrup or syrup pressure being supplied for the
indicated freezing cylinder. If the unit is in the AUTO
or PRIME modes, the PRODUCT NOT READY light
will illuminate and a warning tone will sound for that
freezing cylinder. At this time, replace the
appropriate bag-in-the-box. As a safety feature, the
refrigeration system automatically stops to prevent a
freeze-up in the freezing cylinder.
If a syrup out condition occurs on one side, that side
will enter the HOLD mode at which time the
refrigeration remains off and the beater continues to
run. The opposite side will not be affected. When the
syrup is satisfied, the unit will refill the product tank,
and then automatically return to the AUTO mode.

On the LCD, if the word “OUT” appears next to the
word “WATER”, it indicates a lack of water being
supplied to the freezer. In addition, the product light
will illuminate and a warning tone will sound. This
will continue until the proper amount of water is
supplied to the freezer. If the water is not supplied
within one minute, the machine will shut down and a
fault message will appear.
Audio Alarm Silencer
The audio alarm will be disabled if the ALARM
SILENCE key is pressed. If a new fault or fault
condition occurs or the system mode changes, the
audio alarm will be re-enabled automatically. If the
audio alarm is silenced for greater than 30 minutes
without correcting the fault, it will be re-enabled
automatically.
Product Light
When the light is continuously lit (not flashing) it
indicates that there is an “OUT” condition for syrup,
water, or CO2.
When the light is flashing, it indicates that the
product is not at serving viscosity. This will occur
during the initial freeze down, a defrost cycle and a
FAULT condition and during power saver modes.
Sampling Valve
The sampling valve is located behind the lower front
panel. The sampling valve is used to obtain a brix
reading.
Daily Procedures
The following procedure should be performed daily.
Remove the splash shield and front drip tray. Take
these parts to the sink and brush-clean them.
Re-install the parts onto the freezer. Use a clean,
sanitized towel and wipe down the front of the
machine, including the doors and spouts.
