installation instructions, please see the installation
checklist.
Installer Safety
IMPORTANT! In all areas of the world,
machines should be installed in accordance with existing
local codes. Please contact your local authorities if you
have any questions.
Care should be taken to ensure that all basic safety
practices are followed during the installation and
servicing activities related to the installation and service
of Taylor®machines.
• Only Taylor service personnel should perform
installation, maintenance, and repairs on Taylor
machines.
• Authorized service personnel should consult
OSHA Standard 29CFRI910.147 or the
applicable code of the local area for the industry
standards on lockout/tagout procedures before
beginning any installation or repairs.
• Authorized service personnel must ensure that
the proper personal protective equipment (PPE)
is available and worn when required during
installation and service.
• Authorized service personnel must remove all
metal jewelry, rings, and watches before
working on electrical equipment.
DANGER! The main power supply(s) to the
machine must be disconnected prior to performing any
installation, maintenance, or repairs. Failure to follow this
instruction may result in personal injury or death from
electrical shock or hazardous moving parts, as well as
poor performance or damage to the machine.
Note: All repairs must be performed by a Taylor service
technician.
WARNING! This machine has many sharp
edges that can cause severe injuries.
Site Preparation
Review the area the machine is to be installed in before
uncrating the machine, making sure that all possible
hazards the user or machine may come into have been
addressed.
WARNING! Only install this machine in a
location where its use and maintenance is restricted to
trained personnel. Failure to comply may result in
personal injury.
For Indoor Use Only: This machine is designed to
operate indoors, under normal ambient temperatures of
70°F to 75°F (21°C to 24°C). The freezer has
successfully performed in high ambient temperatures of
104°F (40°C) at reduced capacities.
WARNING! This machine 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 machine. Failure to follow this instruction may result
in electrocution.
CAUTION! This machine must be installed on
a level surface to avoid the hazard of tipping. Extreme
care should be taken in moving this machine for any
reason. Two or more persons are required to safely move
this machine. Failure to comply may result in personal

Air-Cooled Machines
Do not obstruct air intake and discharge openings.
Air-cooled machines require 6 in. (152 mm) minimum air
space around all sides of the freezer to allow for
adequate airflow across the condenser(s). Failure to
allow adequate clearance can reduce the refrigeration
capacity of the freezer and possibly cause permanent
damage to the compressor.
Water Connections
(Water-Cooled Machines Only)
An adequate cold-water supply must be provided with a
hand shutoff valve on the two water inlet lines. On the
underside of the base pan, three 1/2 in. IPS water
connections for inlet, outlet, and carbonator have been
provided for easy hookup. Permanently connect the
machine using 1/2 in. (12.7 mm) inside diameter water
lines. Flexible lines are recommended, if local codes
permit.
Failure to use adequately sized water lines may cause
the machine to go off 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.
There are two water in connections and one water out
connection. Do not install a hand shutoff valve on the
water out line. Water should always flow in this order:
first, through the automatic water valve; second, through
the condenser; and third, through the outlet fitting to an
open trap drain.
Important! Water pressures are preset at the factory. Do
not adjust the water. Improper water adjustments may
cause operation discrepancies.
IMPORTANT! A backflow prevention device is
required on the incoming water connection side. Please
see the applicable national, state, and local codes for
determining the proper configuration. Water pressure to
the unit must not exceed 150 psi (1034 kPa).
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 carbon particles 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.

Refrigerant
CAUTION! This machine contains fluorinated
greenhouse gases (F-Gas) to provide refrigeration using
a hermetically sealed circuit or within foam insulation.
This machine’s type of gas, quantity, Global Warming
Potential (GWP), and CO2tonnes equivalent information
is recorded on the machine’s data label. The refrigerant
used is generally considered nontoxic and
nonflammable. 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 approximately 80% will allow for
normal expansion.
CAUTION! Use only approved refrigerant
listed on the machine's data label or authorized through a
manufacturer's technical bulletin. The use of any other
refrigerant may expose users and operators to
unexpected safety hazards.
WARNING! Refrigerant liquid sprayed onto the
skin may cause serious damage to tissue. Keep eyes
and skin protected. If refrigerant burns should occur,
flush the area immediately with cold water. If burns are
severe, apply ice packs and contact a physician
immediately.
NOTICE! Taylor reminds technicians to be
aware of and in compliance with local government laws
regarding refrigerant recovery, recycling, and reclaiming
systems. For information regarding applicable local laws,
please contact your local authorized Taylor distributor.
IMPORTANT! Refrigerants and their
associated lubricants may be 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.

inside the freezer should be set at 40 to 45 psi (2.76
to 3.10 bar).
13. The CO2low-pressure switch requires at least 21 psi
(1.45 bar) before the freezer will start. It is set to cut
out at 7 psi (0.483 bar) and cut in at 21 psi (1.45 bar).
14. There are check valves in the CO2, syrup, and water
lines to prevent any backflow of soda water, product,
or CO2.
Remote Condenser Assembly Units
Preparation
Uncrate the condenser assemblies. After inspecting them
for damage, position them in the desired location. Two
remote condenser assemblies are required for each
freezer (one condenser per compressor).
Remote condensers require a minimum of 6 in. (152 mm)
air space on the rear and both sides. This is necessary
for adequate air flow. Failure to follow this instruction may
cause poor freezer performance and damage the
equipment.
Refrigeration Charging and Line
Construction
Each condenser assembly is shipped with a refrigerant
holding charge sufficient to prevent moisture
contamination 8 oz. (227 g) HP62. This holding charge
will become part of the total system charge.
The condenser assemblies are shipped with the total
amount of refrigerant required for a typical installation of
50 ft. (15 m). For other installation configurations, use the
following chart for line sizing and for adding required
refrigerant.
Recommended System Refrigerant Charge
Table 1-1
Note: Maximum line length is 100 ft. (30 m) To meet
individual installation requirements, the lines must be
purchased and constructed locally.
Line Size
Liquid Line—Requires 3/8 in. refrigerant grade copper
tubing (hard or soft).
Note: Insulating the liquid line is recommended if it is
exposed to high ambient conditions. This will reduce heat
accumulation and prevent the formation of flash gas in
the liquid line.
Discharge Line—Requires 1/2 in. refrigerant grade
copper tubing (hard or soft).

Remote Condenser Installation
1. Install refrigeration lines from the freezer to the
condenser assemblies. Do not create oil traps.
2. Normally, any straight run of tubing must be
supported near each end of the run. Long runs
require additional supports. As a guide, 3/8 in. to 3/4
in. copper should be supported every 5 ft. (1.52 m).
When changing directions, no corner should be left
unsupported. Supports should be placed a maximum
of 2 ft. (0.61 m) in each direction from the corner. If
soft copper tubing is used, make sure it is not kinked
or flattened. If hard drawn copper tubing is used, use
only long radius elbows.
3. Braze the quick-connect/disconnect couplings and
access tees on the freezer end of the refrigeration
lines. The couplings and access tees are supplied
with the freezer or condenser assembly.
4. Braze the supplied quick-connect/disconnect
couplings on the condenser assembly end of the
refrigeration lines. The couplings are supplied with
the condenser assembly.
Note: Wrap a wet cloth around the brass coupling
bodies to prevent heat damage to the seal.
5. Test the field-constructed lines for leaks.
6. Evacuate the field-constructed refrigerant lines using
the access fittings brazed on the freezer end of the
refrigeration lines.
7. When the evacuation process is complete, relieve
the vacuum with 4 oz. (113 g) HP62 refrigerant per
line, for a total of 8 oz. (227 g). This procedure will
prevent moisture contamination during freezer and
condenser assembly connection and will complete
the total charge.
Remote Condenser Refrigeration
Connections
Connect the refrigerant line quick-connect/disconnect
(QD) couplings to the mating (QD) couplings on the
condenser assembly by performing step 1 through
step 6. When complete, repeat the instructions to
connect the couplings on the freezer.
1. Remove the shipping caps from the 
quick-connect/disconnect coupling on the condenser
assembly.
2. Thoroughly clean and lubricate the mating surfaces
of the quick-connect/disconnects.
Note: Use polyolester oil to lubricate the surfaces.
3. Manually thread the coupling halves together to
ensure proper mating of the threads.
4. Using properly sized wrenches, tighten the coupling
halves until the round, flat surfaces of inner coupling
bodies completely depress one another.
5. Once the flat surfaces are completely depressed,
tighten the couplings an additional 1/4 turn. This step
is necessary to ensure that the knife edge of the seal
seats into the brass seat of the coupling halves,
forming a leak-proof joint (metal seal).

6. Check all connections for leaks.
Repeat step 1 through step 6 to connect the 
refrigerant line QD couplings to the mating QD 
couplings on the freezer.

To the Operator
The freezer(s) you have purchased has been carefully
engineered and manufactured to give you dependable
operation.
This machine(s), 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.
IMPORTANT! This manual should be read
before operating or performing any maintenance on the
machine.
Your Taylor machine will NOT compensate for and/or
correct any errors made during the setup or filling
operations. Thus, the initial assembly, setup, and priming
procedures are of extreme importance. It is strongly
recommended that all personnel responsible for the
machine's operation, including assembly and
disassembly, go through these procedures together in
order to be properly trained and to make sure that all
personnel understand their role in using and maintaining
the machine.
If you should require technical assistance, please contact
your local authorized Taylor distributor.
Note: Your Taylor warranty is valid only if the parts are
authorized Taylor parts, purchased from the local
authorized Taylor distributor, and only if all required
service work is provided by a Taylor service technician.
Taylor reserves the right to deny warranty claims on
machines or parts if unapproved parts or incorrect
refrigerant were installed in the machine, system
modifications were performed beyond factory
recommendations, or it is determined that the failure was
caused by abuse, misuse, neglect, or failure to follow all
operating instructions. For full details of your Taylor
warranty, please see the Limited Warranty section in this
manual.
Note: Constant research results in steady improvements;
therefore, information in this manual is subject to change
without notice.
IMPORTANT! If the crossed-out wheeled-bin
symbol is affixed to this machine, it signifies that this
machine is compliant with the EU Directives as well as
other similar end-of-life 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 delivering the machine to the
appropriate collection facility, as specified by your local
code.
For additional information regarding applicable local
disposal laws, please contact the municipal waste facility
and/or local authorized Taylor distributor.

Compressor Warranty Disclaimer
The refrigeration compressor(s) on this unit are
warranted for the term stated in the Limited Warranty
section in this manual. 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 unit’s refrigeration system, only
the refrigerant specified on the affixed data label should
be used. The unauthorized use of alternate refrigerants
will void your Taylor compressor warranty. It is the unit
owner’s responsibility to make this fact known to any
technician he/she 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.
