Section 1 To 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
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 of any model freezer.
Note: The following procedures should be performed
by a trained service technician.
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 condenser(s). Failure to
allow adequate clearance can reduce the refrigeration
capacity of the freezer and possibly cause permanent
damage to the compressor.
Models 336, 338 & 339 To the Installer
To correct 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 diagram printed
on motor.)
Electrical connections are made directly to the
terminal block 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 soft-serve models covered in
this manual consist of the following: 336, 338 and 339.
These units, when properly operated and cared for, will
produce a consistent quality product. Like all
mechanical products, they 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
for and correct 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 personnel responsible for the
equipment’s operation, both assembly and
disassembly, go through these procedures together in
order to be properly trained and to make sure that no
confusion exists.
In the event 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 .
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.
10
Models 336, 338 & 339Important: To the Operator
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” button and observe the freezer’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 (the
end 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.
