Air Cooled Units
DO NOT obstruct air intake and discharge openings:
existing local codes. Please contact your local
authorities.
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. Install the
deflector provided to prevent recirculation of warm air.
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 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 for both
single head and double head units. DO NOT install a
hand shut--off valve on the water “out” line! Water
should always flow in this order: first, through the
automaticwatervalve;second,throughthe
condenser; and third, through the outlet fitting to an
opentrapdrain.
A back flow prevention device is required
on the incoming water connection side. Please
refer to the applicable National, State, and local codes
for determining the proper configuration.
Electrical Connections
In the United States, this equipment is intended to be
installed in accordance with the National Electrical
Code (NEC), ANSI/NFPA70-1987. 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. In all other areas of the world,
equipment should be installed in accordance with the
FOLLOW YOUR LOCAL ELECTRICAL CODES!
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
This unit is provided with an equipotential
grounding lug that is to be properly attached to the rear

Check Out
Once the unit is installed, it is advisable to check the
following controls and mechanical operations of the
freezer and to make any necessary adjustments. If
applicable, repeat these checks for the second
freezing cylinder on double head units.
Controls
Place the control switch in the “AUTO” position. The
main refrigeration system will operate (compressor,
beater motor, and the condenser fan). The dial light
and the mix low indicator will be illuminated.
Refrigerant
In consideration of our environment, T aylor
proudly uses only earth friendly HFC refrigerants. The
HFC refrigerant used in this unit is R404A. This
refrigerant is generally considered non-toxic and
non-flammable, with an Ozone Depleting Potential
(ODP) of zero (0).
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.
Refrigerant liquid sprayed onto the skin may
cause serious damage to tissue. Keep eyes and skin
protected. If refrigerant burns should occur, flush
immediately with cold water. If burns are severe, apply
ice packs and contact a physician immediately.
Figure 1
If the freezer is water cooled, the automatic water
valve will begin to open and cold water will flow into the
condenser. This will remove heat from the refrigerant.
As the water flows into the open trap drain, it should be
warm to the touch. Place the control switch in the
“OFF” position.
Beater Rotation
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: Thefollowingproceduresmustbe
performed by an authorizedTaylor service
technician.
To correct rotation on a three--phase unit, interchange
any two incoming power supply lines at the freezer
main terminal block only. To correct rotation on a
single--phase unit, 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.
Taylor reminds technicians to be cautious of
government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory Service Department.
WARNING:R404Arefrigerantusedin
conjunction with polyolester oils is 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.

Indicator Light “Mix Low”
The Models 441 and 444 are equipped with a “MIX
LOW” light located on the front of the machine. When
the light begins to flash, it indicates that the mix hopper
has a low supply of mix and should be refilled as soon
as possible. Always maintain at least 3” (76 mm) of mix
in the hopper to allow the mix feed assembly to operate
properly. If you neglect to add mix when the light
begins to flash, a freeze--up may occur, causing
eventual damage to the beater, blades, drive shaft,
and freezer door.

Section 6Operating Procedures
The Model 441 has been selected to show you the
pictured step--by--step operating procedures for both
models contained in this manual. These models, for
practical purposes of operation, are the same.
They both store 20 quarts (18.9 liters) of mix in the
hopper. The mix then flows by gravity through a mix
feed tube down into the freezing cylinder.
Locate your model number below to determine the
characteristics of your freezer:
441: (1) 7 quart (6.6 liter) freezing cylinder.
444: (2) 7 quart (6.6 liter) freezing cylinders.
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 portion.
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 19, “Disassembly” and start
there.

Draining Product From the
Freezing Cylinder
Step 1
Place the control switch in the “OFF” position.
Step 2
Remove the hopper cover, the hopper gasket, and the
mix feed tube. Take these parts to the sink for cleaning.
Step 3
If local health codes permit the use of rerun,place
a sanitized, NSF approved stainless steel rerun
container beneath the door spout. Place the control
switch in the “WASH” position and raise the draw arm.
When all the product stops flowing from the door
spout, lower the draw arm and place the control switch
in the “OFF” position. Place the sanitized lid on the
rerun container and place it in the walk--in cooler.
Note: If local health codes DO NOT permit the use
of rerun, the product must be discarded. Follow the
instructions in the previous step, except drain the
product into a mix pail and properly discard the mix.
Repeat these steps for the second freezing cylinder
on the Model 444.
ALWAYS FOLLOW LOCAL HEALTH CODES.
Cleaning
Step 1
Prepare a pail of approved 100 PPM cleaning solution
(examples: 2--1/2 gal. [9.5 liters] of Kay--5R or 2 gal.
[7.6 liters] of Stera--SheenR). USE WARM WATER
ANDFOLLOWTHEMANUFACTURER’S
SPECIFICATIONS.
Step 2
Pour the cleaning solution into the hopper and allow it
to flow into the freezing cylinder.
Step 3
While the solution is flowing into the freezing cylinder,
brush clean the mix hopper, the mix inlet hole, and the
mix level sensing probe.
Step 4
Place the control switch in the “WASH” position. This
will cause the cleaning solution in the freezing cylinder
to agitate.
Step 5
Place an empty mix pail beneath the door spout and
raise the draw arm. Draw off all the cleaning solution.
When the solution stops flowing from the door spout,
lower the draw arm and place the control switch in the
“OFF” position.
Rinsing
Step 1
Pour two gallons (7.6 liters) of cool, clean water into
the mix hopper. With the brushes provided, scrub the
mix hopper, the mix inlet hole, and the mix level
sensing probe.
Step 2
With a mix pail beneath the door spout, place the
control switch in the “WASH” position and raise the
draw arm. Drain all the rinse water from the freezing
cylinder. When the rinse water stops flowing from the
door spout, lower the draw arm and place the control
switch in the “OFF” position.
Repeat this procedure until the rinse water being
drawn from the freezing cylinder is clear .
Repeat these steps for the second freezing cylinder
on the Model 444.
Repeat Steps 1 through 5 for the second freezing

Disassembly
Step 3
From the freezer door(s) remove:
Note: Failure to remove parts, brush clean and then
air dry these parts, will result in damage to the related
parts.
Step 1
BE SURE THE CONTROL SWITCH IS IN
THE “OFF” POSITION TO ELIMINATE THE
CHANCE OF MOVING PARTS.
Step 2
Remove the handscrews, the freezer door, the gasket,
the front bearing, the beater, the scraper blade(s), and
the drive shaft from the freezing cylinder. Take these
parts to the sink for cleaning.
Step 3
Remove the rear drip pan from the side panel.
Note: If the drip pan is filled with an excessive amount
of mix, it is an indication that the drive shaft seal should
be replaced or was improperly lubricated.
Repeat these steps for the second freezing cylinder
on the Model 444.
Step 4
Remove the front drip tray and the splash shield.
Sthe gasket(s)
Sthe front bearing(s)
Sthe draw valve(s)
Remove all o--rings.
Note: To remove o--rings, use a single service towel
to grasp the o--ring. Apply pressure in an upward
direction until the o--ring pops out of its groove. With
the other hand, push the top of the o--ring forward. It
will roll out of the groove and can be easily removed.
If there is more than one o--ring to be removed, always
remove the rear o--ring first. This will allow the o--ring
to slide over the forward rings without falling into the
open grooves.
Step 4
Thoroughly brush clean all disassembled parts in the
cleaning solution, making sure all lubricant and mix film
is removed. Take particular care to brush clean the
draw valve core in the freezer door(s). Place all the
cleaned parts on a clean dry surface to air dry
overnight.
Step 5
Return to the freezer with a small amount of cleaning
solution. With the black bristle brush, brush clean the
rear shell bearing(s) at the back of the freezing
cylinder(s).
Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(examples: Kay--5R or Stera--SheenR). USE WARM
WATER AND FOLLOW THE MANUFACTURER’S
SPECIFICATIONS.
If an approved cleaner other than Kay--5Ror
Stera--SheenR is used, dilute it according to the label
instructions. IMPORTANT: Follow the label directions.
Too STRONG of a solution can cause parts damage.
Too MILD of a solution will not provide adequate
cleaning. Make sure all brushes provided with the
freezer are available for brush cleaning.
Step 2
Remove the seal(s) from the drive shaft(s).

Section 7Important: Operator Checklist
During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES.
Cleaning and sanitizing schedules are governed
by federal, state, or local regulatory agencies,
and must be followed accordingly. If the unit
has a “Standby mode”, it must not be used in
lieu of proper cleaning and sanitizing
procedures and frequencies set forth by the
ruling health authority. The following check
points should be stressed during the cleaning
and sanitizing operations.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
T roubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize the machine
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. Be sure there is a generous
amount of cleaning solution on the brush.
j 5. IF LOCAL HEALTH CODES PERMIT THE
USE OF RERUN, make sure the mix rerun is
stored in a sanitized, covered stainless steel
container and is used the following day. DO
NOT prime the machine with rerun. When using
rerun, skim off the foam and discard, then mix
the rerun with fresh mix in a ratio of 50/50 during
the day’s operation.
j 6. On a designated day of the week, run the mix as
low as feasible and discard after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform counts.
j 7. 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 8. The temperature of the mix in the mix hopper
and walk--in cooler should be below 40_F.
(4.4_C.).
Regular Maintenance Checks
j 1. Rotate scraper blades to allow both sides of the
knife edge to wear evenly. This will contribute to
self--sharpening and help maintain fast, efficient
freezing.
j 2. Replace scraper blades that are nicked,
damaged or worn.
j 3. Before installing the beater, be certain that
scraper blades are properly attached over the
pins.
j 4. Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and be
certain it is properly cleaned.
j 5. 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 6. Dispose of o--rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.

j 7. Follow all lubricating procedures as outlined in
“Assembly”.
j 8. Check the condensers for accumulation of dirt
and lint. Dirty condensers will reduce the
efficiencyand capacityof the machine.
Condensers should be cleaned monthly with a
soft brush. Never use screwdrivers or other
metal probes to clean between the fins.
Note: For machines equipped with an air filter,
it will be necessary to vacuum clean the filters
on a monthly schedule.
j 9. 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 technician.
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 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 the spring in the water
valve. Use air pressure on the outlet side to blow out
any water remaining in the condenser. This isextremely important. 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 the
beater, blades, drive shaft, and freezer door. Place
these parts in a protected, dry place. Rubber trim parts
and gaskets can be protected by wrapping them with
moisture--proof paper. All parts should be thoroughly
cleaned of dried mix or lubrication which attract mice
and other vermin.
