Air Cooled Units
FOLLOW YOUR LOCAL ELECTRICAL CODES!
DO NOT obstruct air intake and discharge openings:
Each unit requires one power supply for each data
label on the unit. Check the data label(s) on the freezer
for branch circuit overcurrent protection or fuse, circuit
ampacity, and other electrical specifications. Refer to
the wiring diagram provided inside of the electrical box
for proper power connections.
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 compressors.
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!

Beater Rotation
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.
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: The following procedures must be
performed by an authorized Taylor service
technician.
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.
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. The terminal block is provided in the
main control box located behind the panel in the rear
of the syrup compartment.
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.
Refrigerant
WARNING: R404A refrigerant used in
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.
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.

Section 2
To the Operator
The freezer you have purchased has been carefully
engineered and manufactured to give you dependable
operation. The Taylor Model PH90, when properly
operated and cared for, will produce a consistent
quality product. Like all mechanical products, this
machine 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.
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.
This Operator’s Manual should be read before
operating or performing any maintenance on your
equipment.
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.
Your Model PH90 will NOT eventually compensate
and correct for 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, study these procedures in order to be
properly trained and to make sure that no
misunderstandings exist.
In the event you should require technical assistance,
please contact your local authorized Taylor Distributor.
Note: Warranty is valid only if the parts are authorized
Taylor parts, purchased from an authorized Taylor
Distributor, and the required service work is provided
by an authorized Taylor service technician. Taylor
reserves the right to deny warranty claims on
equipment or parts if non--approved parts or
refrigerant were installed in the machine, system
modifications were performed beyond factory
recommendations, or it is determined that the failure
was caused by neglect or abuse.
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.
Note: Constant research results in steady
improvements; therefore, information in this
manual is subject to change without notice.
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.
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.

Power Switch
Liquid Crystal Display
The power switch is located under the control panel on
the left hand side of the unit. When placed in the ON
position, the power switch allows Softech panel
operation.
Located on the front control panel is the Liquid Crystal
Display (LCD). The LCD is used to show what mode
of operation the freezer is in and whether or not there
is sufficient mix.
Indicator Lights
Heater Switch
Mix Low -- When the MIX LOW light begins to flash,
it indicates the mix hopper has a low supply of mix and
should be refilled as soon as possible. The word
“LOW” will also display on the LCD indicator next to the
word “MIX”.
The heater switch is located under the control panel on
the right hand side of the unit. When placed in the ON
position, the heater switch controls power to the
heated syrup topping rail.
Mix Out -- When the MIX OUT light begins to flash, it
indicates the mix hopper has been almost completely
exhausted and has an insufficient supply of mix to
operate the freezer. The word “OUT” will also display
on the LCD indicator next to the word “MIX”. At this
time the AUTO mode is locked out and the freezer will
be placed in the STANDBY mode. To initiate the
refrigeration system, add mix to the mix hopper and
press the AUTO keypad. The freezer will automatically
begin operation.
Reset Mechanism
The reset buttons are located in the syrup
compartment, behind the syrup tanks. There is one for
each side of the freezer.
Heat Mode -- When the HEAT MODE light is flashing,
it indicates that the freezer is in the process of a heat
cycle.
The reset mechanism protects the beater motor from
an overload condition. Should an overload occur, the
reset mechanism will trip. To properly reset the freezer,
place the power switch in the OFF position. Press the
reset button firmly. Turn the power switch to the ON
position. Clear the fault. Press the WASH keypad and
observe the freezer’s performance. Open the side
access panel to check if the beater motor is turning the
drive shaft in a clockwise (from the operator end)
direction without binding.
Clean Manually -- When the CLEAN MANUALLY light
is flashing, it indicates that the machine must be
disassembled and brush cleaned within 24 hours.
When all four indicator lights are flashing, this signifies
a locked condition. When MIX LOW and MIX OUT
lights are flashing only, this signifies an unlocked
condition.
Do not use metal objects to press the reset
button. Failure to follow this instruction may
result in electrocution.
Flavor Selector Keypad
Four shake flavors are offered from the Model PH90
freezer: chocolate, strawberry, vanilla (unflavored
product), and an optional flavor. Press the desired
shake flavor keypad and open the draw valve. Product
and syrup will automatically blend to produce the
chosen flavor.
If it is turning properly, press the WASH keypad to
cancel the cycle. Press the AUTO keypad on both
sides of the machine to resume normal operation. If
the freezer shuts down again, contact service
technician.

After the safety timeout has been completed, and the
power switch is OFF, one of the following screens is
displayed.
Adjustable Draw Handle
The soft serve side of the freezer features an
adjustable draw handle to provide the best portion
control, giving a better, consistent quality to your
product and controlling costs. The draw handle should
be adjusted to provide a flow rate of 5 to 7--1/2 oz. of
product by weight per 10 seconds. To INCREASE the
flow rate, turn the screw COUNTERCLOCKWISE,
and CLOCKWISE to DECREASE the flow rate. In
addition, for purposes of 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 have the restrictive bar on
the BOTTOM.
The first screen is displayed if the machine is not in a
brush clean state. If any of the requirements for a
brush clean have not been met, the time displayed will
remain at 5:00 minutes. When all the requirements for
a brush cleaning are met, and the five minutes expire,
the screen will change to the second screen, which is
the standard power switch OFF screen.

Operating Screen Descriptions
When the machine is powered the system willinitialize.
The screen will display “INITIALIZING”. There will be
four types of data the system will check: LANGUAGE,
SYSTEM DATA, CONFIG DATA, and LOCKOUT
DATA. During the INITIALIZING... LANGUAGE
screen, the alarm will be on. If the system data,
configuration data, or lockout history data has become
corrupt, the following screen will alert the operator that
the system settings may have been changed.

UNIT CLEANED
When the power switch is set in the ON position, the
system mode of operation screen is displayed. In this
example, the machine is ON, but no mode of operation
has been selected. The second line of the display
indicates whether there is a sufficient supply of mix in
the hopper or if there is a LOW or OUT mix condition.
The third line of the display shows the temperature of
the mix hopper. After pressing the AUTO keypad, the
last line of the display shows the month and date
(MM = month, DD = day) that the machine needs to be
disassembled and brush cleaned.

This display indicates the freezer is operating in 3
different modes. The following information is given:
The final phase of the heat treatment cycle is the
cooling phase. Now the freezer must cool the mix
below 41_F. (5_C.). If the product fails to cool in 2
hours, the freezer will lock out.
The left side of the freezer is operating in the
STANDBY mode, and the mix level in the hopper is
OUT. The right side is operating in the WASH and
PUMP modes, and the mix level in the hopper is LOW.
The temperature of the mix in both hoppers is 40_F.
(4.4_C.), and the machine needs to be brush cleaned
on October 31st.
This example illustrates that the temperature is being
lowered, but has not yet reached the set point.

Step 3
Note: Vanilla and strawberry syrup lines use
restrictors at the syrup tank quick disconnect
connection to maintain proper calibration. If thin
viscosity syrups are used in the special tank, it will be
necessary to install a restrictor in the syrup line
connection.
When ready to resume normal operation, press the
AUTO keypad. (See Figure 84.)
Note: This procedure should be done 15 minutes
before product is expected to be served.
Unscrew the quick disconnect from the elbow portion
of the syrup line. Make sure the o--ring rests on the end
of the quick disconnect fitting. Place the restrictor on
top of the o--ring and screw the quick disconnect back
onto the syrup line.
Step 1
Filling the syrup tanks: Pull back on the collar of the
quick disconnect fitting for the air line. Allow the air
pressure to escape from the syrup tank. (See
Figure 86.)
Figure 84
Syrup System
Two main objectives in your opening procedures must
be to: (1) fill the syrup tanks, and (2) calibrate the syrup
flow. This must be checked daily to insure the high
quality shake you desire.
Discard syrup weekly and flush syrup lines at least
once a week. This will prevent syrup clogging the lines
and will break the bacteria chain. See page 60 to
sanitize the syrup system.
Figure 86
The syrup tanks are located in the lower front syrup
compartment. The syrup lines are color spiral
wrapped. Be sure to match the color wrapped syrup
line to the correct syrup flavor. (See Figure 85.)
Disconnect the syrup line after you have disconnected
the air line. (See Figure 87.)

Remove the syrup tank from the compartment.
Remove the syrup tank lid by lifting up on the locking
lever. Fill the syrup tank with syrup to the indicating
mark on the label. DO NOT overfill the tanks. (See
Figure 88.)
Install the syrup sampler to the fitting on one of the
syrup lines. (See Figure 90.)
Figure 90
Figure 88
Replace the tank lid, match and connect the spiral
wrapped syrup line to the syrup tank. Connect the air
line to the syrup tank.
Push the corresponding flavor button for that syrup
flavor. (See Figure 91.)
Repeat this procedure for all syrup tanks.
Step 2
Calibrating the syrup flow must be done on a daily
basis. It is vital that the correct amount of syrup be
incorporated into the mix to obtain a quality shake. The
cause of too thin shakes is often too much syrup. The
cause of too thick shakes is often too little syrup.
To determine the rate of syrup flow, you will need a
syrup sampler and a calibration cup indicating fluid
ounces. The proper rate of syrup flow is 1 fl. oz. (30ml.)
of syrup in 5 seconds. Once this rate is set, the correct
amount of syrup will be blended with the shake base
regardless of the size of shake served. (See
Figure 89.)

Hold an empty courtesy cup beneath the exit point of
the syrup line. Press the CAL keypad (calibrate). A

Recheck the syrup calibration. Tighten the lock nut
after the correct calibration is achieved.
Hold the small portion of the calibrating cup under the
syrup line with the syrup sampler. Press the CAL
keypad. Press the AUTO keypad to check the rate of
syrup flow. After 5 seconds the flow of syrup will
automatically stop. If the amount of syrup received is
1 fl. oz. (30 ml.), the syrup is properly calibrated. (See
Figure 94.)
If more than 1 fl. oz. (30 ml.) is received, the pressure
must be decreased. Loosen the lock nut and turn the
adjusting screw COUNTERCLOCKWISE to zero.
Remove the air line to the syrup tank to allow the
pressure in the tank to escape. Reconnect the air line.
Adjust the regulator to the new pressure setting and
recheck the syrup calibration. Tighten the lock nut.
Repeat the calibration procedures for each
additional syrup line.

Important: Operator Checklist
j 9. Discard remaining mix from freezer during
During Cleaning and Sanitizing
“Manual Brush Cleaning”.
ALWAYS FOLLOW LOCAL HEALTH CODES.
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.
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. CLEANING AND SANITIZING MUST BE
PERFORMED EVERY 14 DAYS.
j 2. Replace blades that are bent, damaged, or
worn.
j 3. Before installing beater, be certain that scraper
blades are properly attached over the beater
pins.
Troubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize machine
regularly, including complete disassembly and
brush cleaning.
j 4. Dispose of o--rings and seals that are worn, torn
or fit too loosely, and replace with new ones.
j 2. Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
mix passageways.
j 5. Check rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and be
certain it is properly cleaned.
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 6. 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. 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. Be sure to have
a generous amount of cleaning solution on the
brush.
j 7. Follow all lubricating procedures as outlined in
“Assembly”.
j 8. On air cooled units, Check the condensers and
air filters for accumulation of dirt and lint. Dirty
condensers or air filters will reduce the
efficiency and capacity of the machine.
Condensers and filters should be cleaned
monthly. The air filters can be removed from
the rear of the freezer and brought to the sink for
cleaning. Use a soft brush to clean between the
fins of the condensers. Never use screwdrivers
or other metal probes to clean between the fins.
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. Empty all syrup from the tanks and discard at
least once a week.
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
maintenance purposes. Deteriorated or
cracked water lines should be replaced only by
an authorized Taylor mechanic.
j 7. Thoroughly clean and sanitize the syrup lines at
least once a week.
j 8. Temperature of mix in mix hopper and walk--in
cooler should be below 40_F. (4.4_C.).

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.
Your local Taylor Distributor can perform this service
for you.
Wrap detachable parts of the freezer such as beater
assembly 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.
Disconnect the freezer from the main power source to
prevent possible electrical damage.
On water cooled freezers, disconnect the water
supply. Use air pressure to blow out any water
remaining in the condensers. This is extremely
important. Failure to follow this procedure may cause
severe and costly damage to the refrigeration system.
