Air Cooled Units
Electrical Connections
DO NOT obstruct air intake and discharge openings:
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. A deflector
is provided to prevent recirculation of warm air. Failure
to allowadequate 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 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”connectionforbothsingle--headand
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.
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

Beater Rotation
Refrigerant
In consideration of our environment, Taylor
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.
Use only R134a refrigerant that conforms to
the AHI standard 700 specification. The use of any
other refrigerant may expose users and operators to
unexpected safety hazards.
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.
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: Thefollowingproceduresmustbe
performed by an authorized Taylor 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

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
refrigerantsarebeingadvertisedas 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 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.
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.
08 1117
To the Operator
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.

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.

Mix Ref
When the MIX REF key is pressed, the light comes on
indicating the mix hopper refrigeration system is
operating. MIX REF is controlled by the left side of the
freezer as viewedfrom the operator end. The MIX REF
function cannot be cancelled unless the AUTO or
STANDBY modes are cancelled first.
Standby
The Separate Hopper Refrigeration System (SHR)
and the Cylinder Temperature Retention System
(CTR) are standard features. The SHR 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 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.
To activate the SHR and CTR, press the STANDBY
key. Remove the air orifice and place the air tube (endwithout the hole) into the mix inlet hole.
When the STANDBY key is pressed, the light comes
on, indicating the CTR (Cylinder Temperature
Retention System) has been activated. In the
STANDBY mode, the WASH and AUTO functions are
automatically cancelled. The MIX REF function is
automatically locked in to maintain the mix in the
hopper.
To resume normal operation, press the AUTO key.
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
When the WASH key 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.
Auto
When the AUTO key 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 REF function is automatically locked in to
maintain the mix in the mix hopper.
Note: An indicating light and an audible tone will
sound whenever a mode of operation has been
pressed. To cancel any function, press the key again.
The light and mode of operation will shut off.
Thermistor Control
The thermistor control is used to vary the “cycle off”
temperature for the shake side of the machine. The
serving temperature of the shake can be adjusted
colder by turning the knob to the right. T o achieve a
warmer temperature, turn the knob to the left.
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
key to cancel the cycle. Turn the power switch to the
OFF position. Press the reset button firmly .
Note: Do not use metal objects to press

Air Tube (Soft Serve)
The air tube serves two purposes. One end of the tube
has a hole and the other end does not.
Figure 1
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 andallows enough mix to enter
the freezing cylinder after a draw.
Air Tube (Shake)
After priming the machine, install the air tube. Install
the air tube in the position that will allow for the hole
marked “1” to be in the down position. This is the AUTO
position, and will allow mix and air to travel to the
freezing cylinder while product is being dispensed.
Figure 2
During long “No Sale” periods, reverse the position of
the air tube. Position the air tube to allow the hole
marked “2” to be in the down position. This is the
STANDBY position, and will prevent any mix from
entering the freezing cylinder.
Note: Be sure to place the air tubes in the correct
position when returning the freezer to the AUTO
position.
Adjustable Draw Handle
(Soft Serve Only)
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.

pumps from the syrup rail. Check the water level in the
heated syrup topping well. Make sure the water is filled
to the indicating mark on the bottom of the well.
Step 2
Place the heater switch in the ON position.
Note: This heating process will take approximately
2--1/2 hours to reach temperature. The water level in
the topping wells must be checked at least once daily.
Step 3
Prepare a pail of approved 100 PPM sanitizing 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. Sanitize the topping pumps by
placing the entire pump assembly in the pail of sanitizing solution. Pump the solution through the assembly
to thoroughly sanitize the pump.

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.
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.
prime 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 or pins.
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 HEAL TH 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 NOT
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 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.

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 winter
storage service for you.
Wrap detachable parts of the freezer such as beater ,
blades, drive shaft, and freezer door, and place them
in aprotected dry place. Rubber trim parts and gaskets
canbeprotectedbywrappingthemwith
moisture--proof paper. All parts should be thoroughly
