Installer Safety
All repairs must be performed by an authorized Taylor
service technician.
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

Site Preparation
Review the area where the machine will be installed
before uncrating the machine. Make sure that all possible
hazards to the user and the equipment 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.
Air-Cooled Machines
Do not obstruct air intake and discharge openings:
The model C706 air-cooled machine requires a minimum
of 6 in. (152 mm) of clearance on both sides and 0 in.
(0.0 mm) in the rear of the machine. This allows for
adequate air flow 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.
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
injury or machine damage.
Water Connections
(Water-Cooled Machines Only)
An adequate cold water supply must be provided with a
hand shutoff valve. On the underside rear of the base
pan, two 3/8 in. iron pipe size (IPS) water connections for
inlet and outlet have been provided for easy hookup. The
machine should be connected using 1/2 in. inside
diameter water lines. Flexible water lines are
recommended if local codes permit. 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 will be only one water-in
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; third, through the outlet
fitting to an open trap drain.
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.
Electrical Connections
IMPORTANT! In the United States, this
machine is intended to be installed in accordance with
the National Electrical Code (NEC), ANSI/NFPA 701987.
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.
In all other areas of the world, the machine should be
installed in accordance with the existing local codes.
Please contact your local authorities if you have any

IMPORTANT! This machine is provided with an
equipotential grounding lug that is to be properly
attached to the rear of the frame by the authorized
installer. The installation location is marked by the
equipotential bonding symbol (5021 of IEC 60417-1) on
both the removable panel and the machine’s frame.
Stationary machines which are not equipped with a
power cord and a plug or other device to disconnect the
machine from the power source must have an all-pole
disconnecting device with a contact gap of at least

0.125 in. (3 mm) installed in the external installation.
Machines that are permanently connected to fixed wiring
and for which leakage currents may exceed 10 mA,
particularly when disconnected or not used for long
periods, or during initial installation, shall have protective
devices to protect against the leakage of current, such as
a GFI, installed by the authorized personnel to the local
codes.
Supply cords used with this machine shall be oil-
resistant, sheathed flexible cable not lighter than ordinary
polychloroprene or other equivalent synthetic elastomer-
sheathed cord (code designation 60245 IEC 57) installed
with the proper cord anchorage to relieve conductors
from strain, including twisting, at the terminals and
protect the insulation of the conductors from abrasion.
Beater Rotation
NOTICE! Beater rotation must be clockwise as
viewed looking into the freezing cylinder.
To correct the rotation on a three-phase machine,
interchange any two incoming power supply lines at the
freezer main terminal block only. To correct rotation on a
single-phase machine, exchange leads inside the beater
motor. (Follow the diagram printed on the motor.)
Electrical connections are made directly to the terminal
block provided in the main control box located behind the
service panel.
It is recommended that beater rotation adjustment be
performed by an authorized Taylor service technician.
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 to 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.
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.

properly trained and to make sure that no confusion
exists.
If you should require technical assistance, please contact
an 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 an authorized Taylor service
technician. Taylor reserves the right to deny warranty
claims on machines or parts if parts not approved by
Taylor 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.
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 machine 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 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 Taylor compressor warranty. It
is the machine owner's responsibility to make this fact
known to any technician they employ.
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 replacement refrigerant either at billable or 
non-billable terms. Taylor will recommend a suitable
replacement if the original refrigerant is banned,
obsoleted, or no longer available during the five year
Taylor 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 machine in question.
