Introduction

Safety

______________________________

Refrigerant

______________________________

We at Taylor Company, are committed to
manufacturing safe operating and serviceable
equipment. The many built-in safety features that
are part of all Taylor equipment are aimed at
protecting operators and trained service technicians
alike.

This manual is intended exclusively for Taylor
Company authorized service personnel.

This equipment must be properly grounded.
Failure to follow this instruction may result in serious
electrical shock.

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. Failure to follow this instruction
may result in electrocution.

Taylor Company uses R404A refrigerant. This
refrigerant is generally considered non-toxic and
non-flammable; however, any gas under pressure is
potentially hazardous.

NEVER fill any refrigerant cylinder
completely with liquid. Filling the cylinder to
approximately 80% will allow for normal expansion.

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.

The Taylor Company 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.

These machines must be placed on a level
surface. Failure to comply may result in personal
injury or equipment damage.

DO NOT install the unit in an area where a
water jet could be used to clean or rinse the freezer.
Failure to follow this instruction may result in serious
electrical shock.

These machines are designed to operate indoors,
under normal ambient temperatures of 70°-75°F
(21°-24°C). The machines have successfully
performed in high ambient temperatures of 104°F
(40°C) at reduced capacities.

NOISE LEVEL: Airborne noise emission does not
exceed 78 dB(A) when measured at a distance of

1.0 meter from the surface of the machine and at a
height of 1.6 meters from the floor.

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.

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 owners’
responsibility to make this fact known to any
technicians they employ.

It should 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 alternate refrigerant as it relates to your
compressor, call the local Taylor Distributor or the
Taylor Factory. Be prepared to provide the
model/serial number of the unit in question.

Adjust higher or lower by turning the adjustment
screw. Clockwise turns raise the pressure and
counterclockwise lower the pressure.

Note: Make expansion valve adjustments with mix
in the cylinder and the freezer in the AUTO mode.
Be sure to allow adequate time for the pressure to
stabilize.

On a water cooled unit, the water valve should be
set to maintain a compressor head pressure of 255
PSI (1,758 kPa).

Water Valve Adjustment

Place your gauge on the high side access port of the
compressor. Turning the adjustment stem on the
water valve clockwise will lower the pressure.

Note: Make this adjustment with mix in the cylinder
and the freezer in the AUTO mode. Be sure to allow
adequate time for pressure to stabilize.

Operating Screen
Descriptions

______________________________

The fluorescent display located in the center of the
control panel is normally blank during the daily
operation of the machine. The display is activated
when the SEL symbol or the Manager’s Menu is
selected. The display screen will also alert the
operator of specific faults detected by the control.

Note: The displays illustrated in this section are
those seen on the Models C708/C709. The Model
C716/C717 versions may vary slightly.

Power Up Memory (Initializing)

The seven segment display should display “00”
during the initializing sequence.

When the machine is powered, the control system
will initialize to perform a system check. The screen
will display “INITIALIZING”. There will be four types
of data the system will check: LANGUAGE,
SYSTEM DATA, CONFIG DATA, and LOCKOUT
DATA.

Language Initialization

is another language initialization fault. English is the
factory default setting.

System Data

System data is protected separately from the rest of
the data in memory. System data includes variables
that change frequently such as the mode the
machine is in, lockout status, serving counters, fault
codes, and others. While System Data is being
checked the following screen is displayed.

Initializing

System Data

If the System Data is corrupted, the machine is set
to OFF, the serving counters are set to zero, and the
faults are cleared. A “SYSTEM CRC ERR” fault is
set and displayed on the VFD. An acknowledgement
(SEL key) is required.

The UVC platform supports multiple languages by
keeping specific strings in battery backed RAM.
After power-up or a CPU reset, the strings are
tested to see if the language strings are present and
not corrupted. If the strings are present and not
corrupted, initialization continues. Otherwise, the
operator is prompted to select a language. While
language strings are being checked for integrity, the
following screen is displayed.

Initializing

Language

Note: If there is a language initialization fault, the
machine will force a language selection prior to the
initializing sequence. The standard menu LED’s
should light, as if it were in a menu. If a language
has been selected, the unit is powered down, the
machine should not ask for a language unless there

Configuration Data

Configuration data is separate from the rest of the
data in the memory. Configuration data is
information entered through operator and service
menus. While Configuration Data is being checked
the following screen is displayed.

Initializing

Config Data

If Configuration data is corrupted, all user and
service settings are set to defaults. A “CONFIG
CRC ERR” fault is set and displayed on the VFD.
The system will continue to operate in its previous
mode but according to default settings.

Lockout Data

Lockout data is protected separately from the rest of
the data in the memory. While the Lockout Data is
being checked, the following screen is displayed.

Once the system has initialized, the number of days
until brush cleaning is required is indicated on the
control panel. The SAFETY TIMEOUT screen will
be displayed with the alarm on for 60 seconds or
until any control symbol is touched.

Initializing

Lockout Data

If Lockout Data is corrupted, all lockout history data
is cleared. A “LOCKOUT CRC ERR” fault is
displayed.

After the memory integrity has been tested, the
Safety Timeout screen will be displayed.

Heat Cycle Data

Heat cycle data is checked separately from the rest
of the data in memory. Each individual Heat Cycle
Data record is monitored for corruption individually.
At the start of a heat cycle, the next Heat Cycle data
record is cleared and data for the heat cycle is
writtentoit.ThecurrentHeatCycleDatais
displayed as the first heat cycle record in the HEAT
CYCLE DATA menu option.

The heat cycle data records are checked for integrity
when the record is accessed, presently only through
the HEAT CYCLE DATA menu option. (For

additional Heat Cycle Data information,
see page 26.)

Heat Treatment Cycle

The function of the Heat Treatment Cycle is to raise
the temperature of the mix in the freezing cylinder
and hopper high enough and quickly enough to
destroy bacteria. When this has been accomplished,
the temperatures must then be returned to a
temperature low enough and quickly enough to
retard spoilage.

The Heat Treatment Cycle must be successfully
completed at least once every 24 hours or the
freezer will automatically lock itself in the STANDBY
mode.

The Heat Treatment Cycle may be started
automatically according to the AUTO HEAT CYCLE
TIME.

IMPORTANT: The freezer must be operating

in either the STANDBY or AUTO mode before a
Heat Treatment Cycle can be started.

There are three phases in a Heat Treatment Cycle:
Heat, Hold and Cool

The Heat Phase

During this phase, the temperatures of the product
in the freezing cylinder and hopper are raised over
150_F(65_C) in 90 minutes or less.

The Hold Phase

During the HOLD phase, the temperature of the
product is “held” over 150_F(65_C) for a minimum
of 35 minutes to ensure the destruction of all harmful
bacteria in the product.

The Hold Phase Timer “times out” after 35 minutes
as long as all freezing cylinder and hopper
temperatures remain above 150_F(65_C) for the
duration of the HOLD phase.

The Cool Phase

During the COOL phase, the product in the freezing
cylinder and the hopper are lowered to 41_F(5_C)
or less. The unit must complete this phase in less
than 90 minutes.

The COOL Phase Timer measures the maximum
allowable time the unit can remain in the COOL
phase. If the timer exceeds 90 minutes, the unit will
lock-out.

The Heat Cycle TT (Total Time) Timer “times out”
the maximum allowable time the unit can remain in
the Heat Treatment Cycle (4 hours). If the timer
exceeds four hours, the unit will lock out. This timer
is a combination of the HEAT, HOLD, and COOL
Phase Times.

The Heat Phase Timer “times out” the maximum
allowable amount of time the unit can remain in the
HEAT phase of the Heat Treatment Cycle. If the
timer exceeds 90 minutes, the unit will lock-out.

When the entire Heat Treatment Cycle has been
completed, the normal display will appear, indicating
that the machine is operating in the STANDBY
mode.

The purpose of the HEAT phase is to raise the
product temperature above 150_F(65_C) within 90
minutes. To satisfy the control system, the product
must actually reach 160_F(71_C) in the freezing
cylinder and 155_F(68_C) in the hopper. This
requirement ensures that the 150_F(65_C)
requirement has been met. Health laws require
these parameters to be 150_F(65_C) in 90 minutes;
however, the actual amount of time the freezer takes
to accomplish this requirement is closer to 60
minutes.

While in the COOL phase, the hopper and freezing
cylinder are operated by Standby temperatures of:

Freezing Cylinder:

Hopper: 39_F(3.9_C) and above “ON”

The COOL Phase concludes when the hopper and
freezing cylinder reach 41_F(5_C). At this point the
machine enters Standby operation. While the time
given for the COOL Phase is 90 minutes, the actual
time is closer to 30 minutes.

Freezer Lock-Out

To comply with health codes, heat treatment system
freezers must complete a heat treatment cycle
daily, and must be disassembled and brush cleaned
a minimum of every 14 days. Brush cleaning is the
normal disassembly and cleaning procedure found in
the Operator Manual. Failure to follow these
guidelines will cause the control to lock the freezer
out of the AUTO mode.

If the Heat Treatment Cycle fails, the screen will
display a failure message and return the freezer to
the STANDBY mode.

Always comply with local guidelines for the
maximum number of days allowed between brush
clean cycles. (See the Manager’s Menu for setting
the BrushClean interval.)

There are two types of freezer lock conditions that
can occur: Hard Lock or Soft Lock. A Hard Lock
requires the machine be disassembled and brush
cleaned. A Soft Lock can be corrected by either
disassembling and brush cleaning the machine, or
by starting another heat treatment cycle.

Hardlock

There are two causes of a hard lock failure. The
freezer will hardlock if either the Brush Clean Timer
has elapsed or if a Thermistor Failure (Freezing
Cylinder or Hopper) occurred during a Heat cycle.

1. The following screen will be displayed if a Brush

Installing a jumper on the left or right interface board forces the liquid solenoid valves, the hot
gas soleniod valves, and the suction solenoid to be energized on the corresponding side of the
unit. Removing the jumper ends their operation. This is used for reclaiming and evacuation of
the refrigeration system only, or manual cycling of the solenoid valves for service check.

A jumper on the W3 of the left interface board enables the syrup heaters.

If a jumper is present on the left interface board, it resets the brush clean date. If a jumper is

Beater Stir Cycles

Standby

When the unit is in the STANDBY mode, the stir
cycle will be activated. The beater stir cycle timer
counts down two minutes (in seconds) and then
activates the beater motor for six seconds. After the
stir cycle, the process will repeat itself; the timer will
count down two minutes, and the beater will run for
six seconds.

Setting Viscosity

Viscosity

Viscosity is the term used when referring to product
appearance, temperature, thickness and firmness.

Soft serve viscosity is measured by monitoring the
amperage load of the beater motor. The amperage
load of the beater motor is low when the product in
the freezing cylinder is liquid. As the product freezes
(thickens), the amperage load increases. When the
amperage load reaches the setpoint, the
refrigeration cycle discontinues.

Hopper Temperature

The hopper temperature setpoint range is 37 - 39°F
(2.8 - 3.9°C). In the AUTO or STANDBY mode the
compressor starts when the hopper temperature is
above the setpoint and stops when the hopper
temperature reaches the setpoint -2°.

The hopper liquid solenoid opens when the hopper
temperature rises above this setpoint and closes
when the hopper temperature is below its
setpoint -2°.

The factory setting (setpoint) for soft serve viscosity
is 2.8 amps. The amperage measurement is
determined by monitoring the L1 leg of power being
delivered to the beater motor. To adjust the serving
viscosity, it may be necessary to raise or lower the
amperage setpoint. Adjust in increases of 0.1 amps.

The serving temperature of soft serve product may
vary throughout the day. The serving temperature
may range from 16_Fto19_F(-8.8_Cto-7.2_C).

freezing cylinder and the hopper. An AXV expansion
valve is used on the freezing cylinder to provide
consistent product quality by maintaining the
evaporating temperature at -15°F (-26°C).

A thermal expansion valve (TXV) is used on the
hopper system for the Cool Phase. The TXV
provides the required control of refrigerant mass flow
to control refrigerant floodback to the compressor.

There is a provision for liquid refrigerant injection to
the compressor suction to control excessive
compressor discharge temperature during the Cool
Phase. The bulb is located on the discharge line
near the compressor to sense when the discharge
temperature approaches 250°F (121°C). Note: The
valve opens at 230°F (110°C).

There are two liquid line solenoid valves to provide
control over the refrigeration to the hopper and
freezing cylinder during the Cool Phase. Both liquid
line solenoids are closed during the Hot Gas Heat
Phase.

Two hot gas solenoid valves are used during the
Heat Phase to direct the compressor discharge gas
to the freezing cylinder and hopper, bypassing the
condenser, freezing cylinder AXV and the hopper
TXV.

When only the hopper is being cooled, a hot gas
bypass valve is used to divert refrigerant gas to the
suction line.

In order to maintain product temperature above
150°F (65.5°C) for 35 minutes during the Hold
Phase, the compressor will cycle on and off.

The main system condenser is a 3-row 5/16” tube
and raised lance fin condenser. The liquid line
receiver helps control the variable amount of free
refrigerant in the system. A filter dryer is provided.
There is a liquid line - suction line heat exchanger on
the main refrigeration system.

Note: This information applies to both sides on the
C716 and C717 - independent systems.

Systems, Controls and Operations

Checking and Setting Refrigeration Valves

This machine is equipped with a safety door lock.
Freezer operation is not allowed in the AUTO,
STANDBY or WASH modes if the door is off. In
order to perform a frost check or a beater rotation
check, the technician must use a magnet to bypass
the reed switch located behind the front panel.

Note: To check various pressures in the
refrigeration system, the machine must be
assembled and have product in both the hopper and
the freezing cylinder.

Gauges should not be installed on these freezers
unless a problem is suspected with the refrigeration
system. Once you have determined there is a
problem, perform the following procedures:

Step 1

Install refrigeration gauges on the service valves
located behind the lower front panel. Remove the
safety cover for complete access.

Step 2

Install a suction line gauge on the schrader valve
fitting on the EPR valve. (See the refrigeration
schematic.)

Step 3

Set the DBV valve (discharge bypass valve) by
placing the freezer in STANDBY. When the freezing
cylinder is satisfied and the hopper only is still
cooling adjust the DBV valve to 10 - 11 psi (69 - 76
kPa) by reading the suction gauge at the service
valves. Adjust the EPR valve to 60 psi (414 kPa) by
reading the suction gauge on the EPR access fitting.

Step 4

When the freezer has cycled off, place the unit in
AUTO. Set the freezing cylinder expansion valve to
20 to 22 psi (138 to 145 kPa) and the water valve to
255 psi (1,758 kPa) if so equipped.

Step 5

Place the freezer into a heat cycle. The hopper only
will heat for the first 10 minutes and then the
freezing cylinder will begin to heat.

Step 6

Once both the hopper and the freezing cylinder are
above 100°F (38°C), set the OPR valve to 40 psi
(276 kPa) by reading the pressures at the service
valves.

Failure to follow these procedures will result in
improperly set valves and poor freezer performance.

To reclaim and recharge a system, install a jumper
on W4 on the interface board to open all solenoids.
Remove the jumper upon completion of the recharge
and check valve settings as outlined above.

Note: Each side must be set individually on the
C716 and C717.

Troubleshooting

Solenoid Valve Failure Troubleshooting

These hot gas units were tested to determine symptoms exhibited by the units when the solenoid valves fail. The
following are the test results.

Barrel Hot Gas Solenoid Valve

a. Stuck Closed: Will cause a failure of the heat cycle, heat phase.
b. Stuck Open/Leaking: Will cause a failure of the heat cycle, cool phase.

Product in the barrel will not freeze down to temperature, or if frozen at time of
malfunction will cause poor product quality. The initial draw with compressor off will
be sloppy.

Suction Pressure will be high (about 5 psi [35 kPa] above setting).

Hopper Hot Gas Solenoid Valve

a. Stuck Closed: Will cause a failure of the heat cycle, heat phase.
b. Stuck Open/Leaking: Will cause a failure of the heat cycle, cool phase.

Will warm product in the hopper above acceptable level.
Pressures: Suction was 30 psi (207 kPa), discharge was 175 psi (1,207 kPa).

Barrel Suction Solenoid Valve

a. Stuck Closed: Product will not freeze properly in Auto, and will fail heat cycle.

Compressor Will Fail Suction pressure dropped to DBV setting and discharge psi also dropped.

Compressor sump temperature rose to 200°F (93°C) in 30 minutes.

b. Stuck Open/Leaking: Product in barrel will cool while the hopper cools with the beater off. The belt is

squealing, and there is low suction psi.
Will not cause a heat cycle failure but will be an issue after long hopper cooling

period in Standby after heat cycle.

Barrel Liquid Solenoid Valve

a. Stuck Closed: Product will not freezer down in the Auto mode or cool in the Standby mode.

Compressor Will Fail Suction pressure was in a vacuum, discharge pressure was 175.

The compressor cut out on internal overload in 9 minutes.

b. Stuck Open/Leaking: Will fail the heat cycle in the heat phase.

The product will be cold and lumpy, and there will be poor ejection.

Hopper Liquid Solenoid Valve

a. Stuck Closed: Will fail heat cycle, cool phase. Product will not cool in Auto or Standby modes.

Suction pressure is below DBV setting with hopper only cooling.

b. Stuck Open/Leaking: Will fail the heat cycle in the heat phase.

In Auto or Standby modes, the hopper product cools to 32°F (0°C).

Troubleshooting

60

Models C708/C709/C716/C717

Hot Gas Bypass Valve (DBV) Solenoid Valve

a. Stuck Closed: Suction will run in a vacuum cooling the hopper only. Frost back occurred at the

compressor.
Sloppy product for initial draw.

b. Stuck Open/Leaking: Trouble setting the barrel suction pressure due to DBV influence. Poor (cold,

lumpy) product quality.
If DBV is set to close to the barrel AXV, cooling will take longer.

Expected results with metering valves out of adju stment:

DBV: Too low could cause system to run in a vacuum with hopper only cooling.

Too high will cause inefficiency if set too close to AXV.

AXV: Too low will cause lower evaporator and product temperatures. Possible heavy scraping of blades

and barrel freeze up.
Too high will cause longer run times, warmer evaporator and product temperatures.

EPR: Too low will cause hopper product to freeze to the sides.

Too high will cause longer run times and could cause the hopper product to be warmer than 40°F
(4.4°C).

OPR: Too low will cause extended heat cycle heat phase times, less efficiency.

Too high will cause over amping of the compressor in the heat cycle heat phase and high pressure
cut out in the cool phase.

Troubleshooting

Bacteria Troubleshooting

Periodic product sampling is taken by a sanitarian.
Bacteria counts should not exceed the following
figures:

Standard Plate Count (SPC) 50,000..........

Coliform 10................................

If the counts exceed the numbers listed, steps
should be taken to locate the cause. Failure to solve
the high counts will result in an unsafe product for

CAUSE OF CONTAMINATION

1. Human contamination. a. Wash hands and arms past elbows.

2. Residue product deposits on mix contact
surfaces (milkstone build-up).

consumption. Educate the operator about how to
prevent high bacteria counts.

Note: High bacteria counts in soft serve yogurt is
normal and necessary. Coliform, however, cannot
be accepted in any product. The following
information will help solve high coliform count
problems.

If sample results indicate a problem, one of
these areas may be a source of contamination.

PREVENTION

b. Wear rubber gloves if cuts or skin conditions

exist.
c. Wash hands periodically throughout the day.
a. Provide the proper brushes.

b. Brush clean all parts and components

thoroughly. Ignoring this will allow formation of

milkstone, a porous substance which will house

bacteria and can lead to contamination of fresh

mix.

3. Worn, damaged, or cracked parts. a. Provide a food grade lubricant (Example: Taylor
Lube).

b. Inspect o-rings for holes or tears. O-rings, seals

and other wear items must be supplied by the
freezer company to meet food industry
standards.

c. During the operating hours, periodically inspect

the rear drip pan for excessive leakage.

4. Improper cleaning and sanitation procedures. a. For cleaning procedures, scrub the sink and
strainers thoroughly before each use. The level
of solution in each basin must allow the largest
component to be submerged. Sanitize and
prime the freezer prior to freezing the product.
After sanitizing a freezer, use fresh mix to flush
remaining sanitizer from the freezing cylinder.

b. Provide the proper brushes, lubricants, and

single service towels.

c. Store sanitizer in a cool, dry place. Use

chemicals according to their labels.

CAUSE OF CONTAMINATION

PREVENTION

4. Improper cleaning and sanitation procedures.

(Continued)

5. Mix stored improperly. a. Rotate stock to use older date code mix first.

d. Use a few good employees to follow the

cleaning procedure correctly and consistently.
Allow the employee uninterrupted time to
complete the cleaning procedure.

e. Hold sanitizing solution in the hopper and the

freezing cylinder for five minutes.

f. Wash and sanitize the tube of lubricant; after

each use, always recap the tube.

g. Parts, components, and brushes should be

air-dried overnight. Never store the equipment in
the storage cooler.

h. Do not neglect daily cleaning practices: wipe the

external areas of the freezer periodically
throughout the day, remove the design caps and
sanitize the area, check the drip trays and
splash shield.

Shelf life of mix is normally 10 days.

b. Mix must never be stacked outside or under

direct sunlight while waiting to be placed in the
cooler.

c. Place the mix directly in the cooler. Always

leave one inch between the mix and other
products to allow air to circulate around the
product.

d. Mix must not remain at room temperature for

long periods of time.

e. Hopper storage must maintain a temperature of

39_F. (3.9_C.). Storage temperatures above
45_F. will allow cell division in as little as one
hour.

f. Once the mix is placed in the hopper, covers

must be properly installed to maintain adequate
refrigeration and to prevent airborne
contaminants from entering the mix.
