Section 1 To the Installer
This machine is designed for indoor use only.
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.
Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut-off valve. On the underside rear of the
base pan, two 3/8” I.P .S. (for single-head units) or two
1/2” I.P.S. (for double-head units) water connections
for inlet and outlet have been provided for easy
hook-up. 1/2” inside diameter water lines should be
connected to the machine. (Flexible 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 shut-off 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 opentrapdrain.
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.
Air Cooled Units
Air cooled units require a minimum of 3” (76 mm) of
clearance around all sides of the freezer to allow for
adequate air flow across the condensers. Failure to
allow adequate clearance can reduce the refrigeration
capacity of the freezer and possibly cause permanent
damage to the compressors.
Electrical Connections
Each freezer requires one power supply. Check the
data label on the freezer for fuse, circuit ampacity and
electrical specifications. Refer to the wiring diagram
provided inside of the electrical box, for proper power
connections.
Models H71 & H84 To th e Installer
performed by a trained service technician.
To correct the rotation on a three-phase unit,
interchange any two incoming power supply lines at
freezer main terminal block only.
To correct rotation on a single-phase unit, change the
leads inside the beater motor. (Follow the diagram
printedonthemotor.)
Electrical connections are made directly to the
terminal block. The terminal block is provided in the
main control box located behind the service panel.

Section 2 To the Operator
The freezer you have purchased has been carefully
engineered and manufactured to give you dependable
operation. The Taylor Models H71 and H84, freezers,
when properly operated and cared for, will produce a
consistent quality product. Like all mechanical
products, this machine will require cleaning and
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 Taylor 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 review these procedures in
order to be properly trained and to makesure that there
is no confusion.
In the event that you should require technical
assistance, please contact your local authorized
Taylor Distributor.
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.
The Taylor Company 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.

Adjustable Draw Handle
This unit features an adjustable draw handle to provide
the best portion control, giving a better, consistent
quality to your product and controlling costs. The draw
handle should be adjusted to provide a flow rate of 5
to 7-1/2 oz. of product by weight per 10 seconds. To
INCREASE the flow rate, turn the screw
COUNTERCLOCKWISE, and CLOCKWISE to
DECREASE the flow rate. In addition, for purposes of
SANITIZING and RINSING, the flow rate can be
increased by removing the pivot pin and placing the
restrictive bar on the TOP. When drawing product,
always have the restrictive bar on the BOTTOM.
IMPORTANT: Once the draw rate is set, tighten the
lock nut with a wrench.
