Section 1To 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. DONOT 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.

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
refrigerantsarebeingadvertisedasdrop-in
replacements for numerous applications. It should be
noted that, in the event of ordinary service to this
machine’s refrigeration system, only the refrigerantspecified 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.

Section 6Operating Procedures
The “Operator Parts Identification” section in this
manual has been included to identify components
referenced in these instructions. If this is the first time
you have read these procedures, please turn to the
“Operator Parts Identification” section, and familiarize
yourself with these components before proceeding
with the instructions.
Each unit stores mix in a hopper. The mix then flows
through a mix feed tube down into the freezing
cylinder. They both have 3.4 quart (3.2 liter) capacity
freezing cylinders and 20 quart (18.9 liter) mix
hoppers; one each for the Model H71 and two each for
the Model H84.
Duplicate, where they apply, the following steps for the
two freezing cylinders on the Model H84.
We begin our instructions at the point where we enter
the store in the morning and find the parts
disassembled and laid out to air dry from the previous
night’s cleaning.
The following procedures will show you how to
assemble the parts into the freezer, sanitize them, and
prime the freezer with fresh mix in preparation to serve
your first product.
Step 1
Lubricate the groove and shaft portion that come in
contact with the bearing on the beater drive shaft. Slide
the seal over the shaft and groove until it snaps into
place. DO NOT lubricate the hex end of the drive shaft.
Fill the inside portion of the seal with 1/4” more
lubricant. Lubricate the flat side of the seal that comes
in contact with the bearing.
Figure 1
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 32 “Disassembly”, and start
there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (Example: Taylor Lube HP).
MAKE SURE POWER SWITCH IS IN THE
“OFF” POSITION! Failure to follow this instruction
may result in severe personal injury from hazardous
moving parts.
Be certain your hands are sanitized before
assembling the freezer.
Note: Make sure the seal is not installed inside-out.
The ridge that protrudes in the center of the sealshould
be on the outside.
Figure 2

Models H71 & H84Operating Procedures
Page 27
Install the drive shaft. 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.
Figure 3
Step 2
Install the beater assembly. First check the scraper
blades for any nicks or signs of wear. If any nicks are
present, replace both blades.
USE EXTREME CAUTION when handling
the beater assembly. The scraper blades are very
sharp and may cause injury.
If the blades are in good condition, take one of the
scraper blades and slip it under the hook at the front
of the beater. Wrap the blade around the beater,
following the helix and pushing the blade down onto
the helix as you wrap. At the back end of the beater,
slip the blade under the hook.
Holding the beater securely, slide the beater into the
freezing cylinder about one-third of the way in. Looking
into the freezing cylinder, align the hole at the rear of
the beater with the flats on the end of the drive shaft.
Slide the beater the remainder of the way into the
freezing cylinder and over the end of the drive shaft.
The beater should fit snugly but not so tightly that the
beater cannot be turned slightly to engage the drive
shaft.
Figure 5
Repeat Steps 1 and 2 for the other side of the freezer
on the Model H84.
Step 3
Assemble the freezer door. Place the large rubber
gasket(s) in the groove(s) on the back side of the
freezer door.
Slide the white plastic front bearing(s) onto the bearing
hub(s), making certain that the flanged end of the
bearing is resting against the freezer door. DO NOT
lubricate the gasket(s) or the front bearing(s).

The function of the Heat Treatment Cycle is to destroy
bacteria by raising the temperature of the mix in the
freezing cylinder and the hopper to a specified
temperature for a specified period of time, and then
bringing the temperature back down low enough to
retard spoilage.
The Heat Treatment Cycle will start at the time
designated in the AUTO HEAT TIME.
IMPORTANT: The level of mix in the mix hopper(s)
must be at the line on the agitator paddle. (The mix low
light must not be on.)
Step 1
The freezer must be in the STANDBY or the AUTO
mode before the Heat Treatment Cycle may be
started. (Both sides of the H84 must be in STANDBY
or AUTO.)

your State or local regulatory agencies and must be
followed accordingly. The following check points
should be stressed during the cleaning and sanitizing
operations.
CLEANING AND SANITIZING MUST BE
PERFORMED EVERY T WO WEEKS.
Troubleshooting Bacterial Count:
j 1. Thoroughlycleanandsanitizemachine
regularly, including complete disassembly and
brush cleaning.
j 2. Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
mix passageways.
j 3. Use the white bristle brush to clean the mix inlet
hole which extends from the mix hopper down
to the rear of the freezing cylinder.
j 4. Use the black bristle brush to thoroughly clean
the rear shell bearing located at the rear of the
freezing cylinder and the drive hub opening in
the rear wall of the mix hopper, on pump style
units. Be sure to have a generous amount of
cleaning solution on the brush.
j 5. Properly prepare the cleaning and sanitizing
solutions. Read and follow 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. Temperature of mix in mix hopper and walk-in
cooler should be below 40_F. ( 4 . 4 _C.).
j 7. Discard remaining mix from freezer during
“Closing Procedures”.
Regular Maintenance Checks:
j 1. Replace scraper blades that are nicked or
damaged. Before installing beater, be certain
that scraper blades are properly attached.
j 2. Check rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and be
certain it is properly cleaned.
j 3. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female hex drive
socket clean and free of lubricant and mix
deposits.
j 4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j 5. Follow all lubricating procedures as outlined in
“Assembly”.
j 6. Check the condenser(s) for accumulation of dirt
and lint. Dirty condensers will reduce the
efficiency and capacity of the machine.
Condensers should be cleaned monthly with a
soft brush.
Note: For machines equipped with an air filter,
it will be necessary to vacuum clean the filters
on a monthly schedule.
Never use screwdrivers or other
metal probes to clean between the fins.
Failure to comply can result in severe personal
injury from electrical shock.
j 7. On water cooled units, check the water lines for
kinks or leaks. Kinks can occur when the
machine is moved back and forth for cleaning or
maintenancepurposes.Deterioratedor
cracked water lines should be replaced only by
an authorized Taylor mechanic.

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 to be left unheated and subject to freezing
conditions.
Disconnect the freezer from the main power source to
prevent possible electrical damage.
On water cooled freezers, disconnect the water
supply. Relieve pressure on spring in water valve. Use
air pressure on the outlet side to blow out any water
remaining in the condenser. This is extremelyimportant. Failure to follow this procedure may cause
severe and costly damage to the refrigeration system.
Your local Taylor Distributor can perform this service
for you.
Wrap detachable parts of the freezer such as beater,
blades, drive shaft, and freezer door, and place in a
protected dry place. Rubber trim parts and gaskets
can be protected by wrapping with moisture-proof
paper. All parts should be thoroughly cleaned of dried
mix or lubrication accumulations which attract mice
and other vermin.
