Air Cooled Units
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. 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.
Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut--off valve. On the rear of the unit, 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. 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.
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

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.
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.

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.
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 alternaterefrigerantas it relatesto 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.

Syrup System
Note: V anilla andstrawberrysyruplinesuse
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.
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.)
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.
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.)
Figure 86
Disconnect the syrup line after you have disconnected
the air line. (See Figure 87.)
Figure 85
Model PH90Operating Procedures

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 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.
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. (30 ml.)
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.)
Figure 90
Push the corresponding flavor button for that syrup
flavor. (See Figure 91.)
Figure 91
Hold an empty courtesy cup beneath the exit point of
the syrup line. Press the CAL keypad (calibrate). A

Inside the syrup compartment is a regulator manifold
assembly with individual pressure regulators to control
the amount of pressure to each tank and syrup line.
(See Figure 95.)

CLOCKWISE.
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.)
Figure 94
Recheck the syrup calibration. Tighten the lock nut
after the correct calibration is achieved.
If more than 1 f l. 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.
Step 4
Remove the syrup sampler. Lightly lubricate the o--ring
on each syrup line fitting. (See Figure 96.)
Step 3
Adjusting the syrup pressure: If the amount of syrup
is less than 1 fl. oz. (30 ml.) the syrup pressure must
be increased. If the amount of syrup is more than 1 fl.
oz. (30 ml.) the pressure must be decreased.

apply) for brush cleaning all the soft serve parts. By
doing so, you will not confuse or interchange these
parts for assembly the next morning. Place the parts
in their proper place in the parts tray.

Sanitizing the Syrup System
Shake Side:
Two main objectives in your closing procedures must
be to:
1.Discard all syrup at least once a week.
2.Flush the syrup lines at least twice a week.
This must be done on a regular basis
a.to keep a build--up of old syrup from clogging
the lines, and
b.to break the bacteria chain which develops in
the tanks and lines.
Remember: Calibrating the syrup flow must be done
once every morning, especially after flushing the syrup
lines.
Step 1
Sanitizing the syrup tanks. Pull back on the collar
of the quick disconnect fitting of the air line. Allow the
air pressure to dissipate from the syrup tank.
Disconnect the syrup line.
Remove the syrup tank from its compartment.
Remove the syrup tank lid by lifting up on the locking
lever, and discard the remaining syrup.
Rinse the syrup tank with clean, warm water.
Pour off all the sanitizing solution and place the tank in
an upside--down position on a clean, dry surface to air
dry.
Repeat this procedure for all the syrup tanks.
Step 2
Sanitizing the syrup lines. Prepare one gallon (3.8
liters) of the recommended sanitizing solution with
warm water in the spare syrup tank. Replace and lock
the tank lid in position. Place this tank in the syrup
compartment.
Connect one of the air lines and the corresponding
syrup line to the syrup tank filled with sanitizing
solution.
Place the power switch in the “ON” position. This will
activate the air compressor to supply pressure to the
syrup system.
Install the syrup sampler to the fitting of the syrup line.
Press the corresponding flavor button for the syrup line
being sanitized.
Place an empty pail beneath the exit point of the syrup
line. Press the CAL keypad. A message will appear on
the LCD.
Press the WASH keypad. Flush the syrup line until the
solution runs clear. Press the CAL keypad to stop the
flow of sanitizing solution.
Note: This procedure will thoroughly clean the syrup
lines and prevent bacteria build--up.
Turn the syrup tank with the sanitizing solution
upside--down. Press the CAL keypad. Press the
WASH keypad to clear the syrup line of any remaining
sanitizer. When the sanitizer has been flushed from
the syrup lines, press the CAL keypad to complete this
step.
Repeat this procedure for all syrup lines.
Step 3
Place the power switch to the OFF position.

Model PH90Operating Procedures
Section 7Important: Operator Checklist
During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES.
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.
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 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 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 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.).
j 9. Discard remaining mix from freezer during
“Manual Brush Cleaning”.
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 blades that are bent, damaged, or
worn.
j 3. Before installing beater, be certain that scraper
blades are properly attached over the beater
pins.
j 4. Dispose of o--rings and seals that are worn, torn
or fit too loosely, and replace with new ones.
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 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 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
efficiencyand capacityof 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 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 mechanic.
Model PH90Important: Operator Checklist

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.
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 extremelyimportant. 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 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.
