Section 1To the Installer
These machines are designed for indoor use only.
DO NOT install the machines 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 1/2” I.P.S. 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 automatic water valve; second,
through the condenser; and third, through the outlet
fitting to an opentrapdrain.
Electrical Connections
Each freezer requires one power supply for each data
label. Check the data label(s) 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.
In the United States, this equipment is intended to be

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 .
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.

Power Switch
When placed in the “ON” position, the power switch
allows SOFTECHR control panel operation.
Indicator Light - “Mix Low”
Located on the front of the machine is a mix level
indicating light. When the light is flashing, 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. If you neglect to
add mix, a freeze-up may occur. This will cause
eventual damage to the beater, blades, drive shaft,
and freezer door.
When the “STANDBY” button is pressed, the light
comes on, indicating the CTR (Cylinder Temperature
Retention System) feature has been activated. In the
“STANDBY” mode, the “WASH” and “AUTO” functions
are automatically cancelled. The mix refrigeration
function is automatically locked in to maintain the mix
in the hopper.
To resume normal operation, press the “AUTO” button.
When the unit cycles off, the product in the freezing
cylinder will be at serving viscosity. At this time, place
the air tube (end with the hole) into the mix inlet hole
and install the air orifice.
“Wash”
Mix Refrigeration Button
When the mix refrigeration button is pressed, the light
comes on indicating the mix hopper refrigeration
system is operating. The mix refrigeration is controlled
by the left side of the freezer as viewed from the
operator end. The mix refrigeration function cannot be
cancelled unless the “AUTO” or “STANDBY” modes
are cancelled first.
“Standby”
The Separate Hopper Refrigeration System (SHR)
and the Cylinder T emperature Retention System
(CTR) are standard features. The SHR feature
incorporates the use of a separate small refrigeration
system to maintain the mix in the hopper below
40_(4.4_C) to assure bacteria control. The CTR
feature works with the SHR to maintain a good quality
product. During long “No Sale” periods, it is necessary
to warm the product in the freezing cylinder to
approximately 35_Fto40_F(1.7_Cto4.4_C) to
prevent overbeating and product breakdown.
When the “WASH” button is pressed, the light comes
on. This indicates beater motor operation. The
“STANDBY” or “AUTO” modes must be cancelled first
to activate the “WASH” mode.
Note: The Model 336 cannot be operated in
the “WASH” mode if the opposite side of the freezer is
in “AUTO”. Failure to comply with this instruction will
cause the rinse or sanitizing solution to freeze.
“Auto”
When the “AUTO” button is pressed, the light comes
on. This indicates that the main refrigeration system
has been activated. In the “AUTO” mode, the “WASH”
or “STANDBY” functions are automatically cancelled.
The mix refrigeration function is automatically locked
in to maintain the mix in the mix hopper.
To activate the SHR and CTR features, press the
“STANDBY” button. Remove the air orifice and place
the air tube (end without the hole) into the mix inlet
hole.
Note: An indicating light and an audible tone will
sound whenever a mode of operation has been
pressed. To cancel any function, press the button
again. The light and mode of operation will shut off.

Reset Button
The reset button is located in the service panel. The
reset protects the beater motor from an overload
condition. If an overload occurs, the reset mechanism
will trip. To properly reset the freezer, press the
“AUTO” button to cancel the cycle. Place the power
switch to the “OFF” position. Press the reset button
firmly.
Note: Do not use metal objects to press the
reset button. Failure to follow this instruction may
result in electrocution.
Turn the power switch to the “ON” position. Press the
“WASH”buttonandobservethefreezer’s
performance. Open the side access panel. Make sure
the beater motor is turning the drive shaft in a
clockwise direction (from the operator end) without
binding.
If the beater motor is turning properly, press the
“WASH” button to cancel the cycle. Press the “AUTO”
button (on both sides of the unit) to resume normal
operation. If the freezer shuts down again, contact a
service technician
Air Tube
The air tube serves two purposes. One end of the tube
has a hole and the other end does not.
1.After priming the machine, lubricate the o-rings
on the air tube (the end with the hole) and
place it into the mix inlet hole. Every time the
draw handle is raised, new mix and air from the
hopper will flow down into the freezing cylinder.
This will keep the freezing cylinder properly
loaded and will maintain overrun.
2.During long “No Sale” periods, remove the air
orifice. Lubricate the o-rings on the air tube (theend without the hole), and place it into the
mix inlet hole. This will prevent any mix from
entering the freezing cylinder.
The air orifice is used to meter a certain amount
of air into the freezing cylinder. The air orifice
maintains overrun and allows enough mix to enter
the freezing cylinder after a draw.
Adjustable Draw Handle
These units feature an adjustable draw handle to
provide the best portion control. The draw handle
should be adjusted to provide a flow rate of 5 to 7-1/2
oz. of product per 10 seconds. To INCREASE the flow
rate, turn the screw COUNTERCLOCKWISE. Turn
the screw CLOCKWISE to DECREASE the flow rate.
During “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 place the restrictive bar on the bottom.

Section 6Operating Procedures
Each unit stores mix in a hopper. The mix then flows
by gravity through an air tube down into the freezing
cylinder. They all have 2.8 quart (2.6 liter) capacity
freezing cylinders. All models have 20 quart (18.9 liter)
mix hoppers.
Duplicate the following procedures, where they apply,
for the second freezing cylinder.
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.
These opening procedures will show you how to
assemble these 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 20, “Disassembly”, and start
there.
Assembly
shaft. Fill the inside portion of the seal with 1/4” more
lubricant and lubricate the flat side of the seal that fits
onto the rear shell bearing.
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. Engage the hex
end firmly into the drive coupling. Be sure the drive
shaft fits into the drive coupling without binding.
DO NOT lubricate the hex end of the drive
Figure 3
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
MAKE SURE THE CONTROL SWITCH IS
IN THE “OFF” POSITION.
Step 1
Install the drive shaft. Lubricate the groove and shaft
portion that comes in contact with the bearing on the
beater drive shaft. Slide the seal over the shaft and

Figure 6
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. If the beater slides in too easily with little or no
resistance, there will not be enough force against the
beater to hold the blades in place. If this is the case,
contact your authorized Taylor service agent.
Repeat Steps 1 and 2 for the other side of the freezer.

Cleaning
Brush Cleaning
Step 1
Prepare two gallons (7.6 liters) of an approved cleaning solution (example: Kay-5R). USE WARM WATER
AND FOLLOW THE MANUFACTURER’S SPECIFI CATIONS.
Step 2
Push down the prime plug. Pour the two gallons (7.6
liters) of cleaning solution into the mix hopper.
Step 3
While the solution is flowing into the freezing cylinder,
brush clean the mix hopper, mix level sensing probe,
and the mix inlet hole.
Step 4
Press the “WASH” button. This will cause the cleaning
solution in the freezing cylinder to agitate.
Step 5
Place an empty pail beneath the door spout and raise
the prime plug.
Step 6
When a steady stream of cleaning solution is flowing
from the prime plug opening in the bottom of the
freezer door, lower the draw handle. Draw off all of the
solution.
Step 7
Once the cleaner stops flowing from the door spout,
raise the draw handle and press the “WASH” button,

Disassembly
Step 1
BE SURE THE POWER SWITCH IS IN THE
“OFF” POSITION. MAKE SURE NO LIGHTS ARE
LIT ON THE CONTROL PANEL.
Step 2
Remove the handscrews, freezer door, beaters,
scraper blades, and drive shafts from the freezing
cylinders. Take these parts to the sink for cleaning.
Step 3
Remove the front drip tray and the splash shield.
Step 1
Prepare a sink with an approved cleaning solution
(example: Kay-5R). USE WARM WATER AND
FOLLOWTHEMANUFACTURER’SSPECIFICATIONS. If another approved cleaner is used, dilute
it according to the label instructions. (IMPORTANT:
Follow the label directions. Too STRONG of a solution
can cause parts damage, while too MILD of a solution
will not provide adequate cleaning.) Make sure all
brushes provided with the freezer are available for
brush cleaning.
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 and 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 6
Remove the rear drip pan and take it to the sink for
cleaning.
Note: If the drip pan is filled with an excessive amount
of mix, refer to the Troubleshooting Guide.
Step 7
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 cores in the freezer door. Place all the
cleaned parts on a clean, dry surface to air dry
overnight.
Step 8
Wipe clean all exterior surfaces of the freezer.

Section 7Important: Operator Checklist
During Cleaning and Sanitizing
Cleaning and sanitizing schedules are governed by
your State or local regulatory agencies and must be
followed accordingly. The following check points
should be stressed during the cleaning and sanitizing
operations.
WERECOMMENDDAILYCLEANINGAND
SANITIZING.
ALWAYS FOLLOW LOCAL HEALTH CODES.
T roubleshooting 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. Be sure to have 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 used the following day . DO NOTprime the machine with rerun. When using
rerun, skim off the foam and discard. Mix the
rerun with fresh mix in a ratio of 50/50 during the
days operation.
j 6. On a designated day of the week, run the mix as
low as feasible and discard it 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. Replace scraper blades that are nicked or
damaged.Beforeinstallingthebeater
assembly, be certain that scraper blades are
properly attached to the helix.
j 2. Check the 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. If your machine is air cooled, check the
condensers 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. 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.
Caution:Alwaysdisconnect
electrical power prior to cleaning the
condenser.
j 7. If your machine is equipped with an auxiliary
refrigerationsystem, check the auxiliary
condenser for accumulation of dirt and lint. Dirty
condenserswillreducetherefrigeration
capacity of the mix hopper. Condensers must
be cleaned monthly with a soft brush. Never
use screwdrivers or other metal probes to clean
between the fins.
Caution:Alwaysdisconnect
electrical power prior to cleaning the
condenser.
j 8. If your machine is water cooled, check the water
lines for kinks or leaks. Kinks can occur when
the machine is moved back and forth for
cleaningormaintenancepurposes.
Deteriorated or cracked water lines should be
replacedonlybyanauthorizedTaylor
distributor.
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, and then add a
liberal amount of permanent type auto anti-freeze.
This is extremely important. Failure to follow this
procedure may cause severe and costly damage to the
refrigeration system.
Your local Taylor Distributor can perform this winter
storage service for you.
Wrap detachable parts of the freezer such as beater ,
blades, drive shaft, and freezer door, and place them
in a protected dry place. Rubber trim parts and gaskets
canbeprotectedbywrappingthemwith
moisture-proof paper. All parts should be thoroughly
cleaned of dried mix or lubrication which attract mice
and other vermin.
