water valve is factory set to maintain a high pressure
of 235 PSI (1,620 kPa). To adjust the high pressure,
place the gauge on the high side access port. Turn
the adjustment knob on the water valve clockwise to
lower the high side pressure and counterclockwise
to raise the pressure.
The high side pressure switch is factory set at 440
PSI (3,034kPa) for 404A/HP62. In the event of a
water loss, this switch will sense a rise in pressure
and deactivate the unit.
EPR Valve Setting
The product temperature in the mix hopper is
maintained by the main refrigeration system and can
be adjusted by the EPR (evaporator pressure
regulator) valve. The EPR valve is factory set at 67 -
69 PSI (462 - 476 kPa) in order to maintain hopper
product temperature below 40_F(4_C). To adjust
the hopper temperature, place the gauge on the
access port at the inlet of the EPR valve. With the
compressor running, loosen the locking nut and turn
the adjustment screw (located on the top of the
valve) clockwise to raise hopper temperature and
counterclockwise to lower the temperature. When
the adjustment is complete, tighten the locking nut.

Models 358 & 359 Introduction
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.
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: 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.
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.
Taylor will continue to monitor the industry and test
new alternate refrigerants 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.

Controls & Systems Models 358 & 359
Thermistor Control
Function
The thermistor control maintains product
temperature in the freezing cylinder by monitoring
the resistance of the thermistor probe.
Thermistor Probe (038061--20)
The resistance value of the thermistor probe
corresponds with the product temperature in the
freezing cylinder. As the product becomes colder,
the probe resistance increases. As the product
becomes warmer, the probe resistance decreases.
Approximate probe resistance readings:
S10,000 OHMS at room temperature
(77°F/25°C)
S46,012 OHMS at product temperature
(20°F/-6.6°C)
Operation
The thermistor probe is positioned in the bulb-well
located at the front of the freezing cylinder. The
thermistor control becomes operational when
powered by the 24 VAC transformer.
When the desired product is achieved (control
set-point), the thermistor control relay relaxes and
discontinues sending L1 power to the compressor
relay coil.
When the product in the freezing cylinder warms up
.5°F (.3°C) above the control set-point, the
thermistor control relay closes, sending L1 power to
the compressor relay coil. The refrigeration system
will run until the control set-point is achieved.
Anticipator
The anticipator signals the thermistor control to
activate the refrigeration system whenever product
is drawn. As the draw valve is raised and the freezer
draw switch closes, continuity is created between
the thermistor control anticipator terminals. The
thermistor control relay will close within .5 seconds
to start the refrigeration system. The control set
point will shift 8°F (4.4°C) approximately 5 seconds
after the draw switch is released. The set point shift
will change 3.5°F (2°C) and remain in that state for
20 seconds. The set point will then return to its
original setting.
Setting Temperature
1. Position the thermistor fine adjustment at
mid-range. This will limit the fine adjustment
temperature range to ±2_F(±1_C).
2. Turn the coarse adjustment clockwise to the
coldest setting.
3. With the freezer correctly primed, place the
power switch in the “AUTO” position.
4. After the appropriate freezing time, test the
product temperature. When a sample portion
temperature is approximately 1_above the
desired temperature setting, slowly turn the
coarse adjustment counterclockwise (warmer)
until the refrigeration system cycles off.
5. Allow the refrigeration system to cycle through
at least two “off” cycles. After the unit cycles
off, draw a sample of product and check the
temperature. Readjust the coarse adjustment
as required, but make only small adjustments.
Note: The anticipator automatically activates the
refrigeration system within 5 seconds after the draw
valve is opened. If several small samples are drawn,
the temperature may drift lower. To accurately set
the control, let the product temperature stabilize by
allowing the thermistor control to cycle the freezer
on and off by the control set-point, not the
anticipator.

Models 358 & 359 Controls & Systems
Service Tips
If a problem arises with the thermistor control
assembly, identify and replace only the faulty
component. For example, if the probe is defective,
replace only the probe.
SA varistor must be connected to the
thermistor control 24 VAC terminals in order
to protect the control from voltage spikes
(varistor part number X31547).
SFill the bulb-well with antifreeze before
installing the thermistor probe.
SBe sure the probe is installed completely
into the bottom of the bulb-well.
Note: Lower the probe to the point where the wires
extend from the probe and a resistance is felt. This
indicates the probe is installed completely in the
bottom of the bulb-well.
If the thermistor relay which starts the compressor
will not close, check the following items:
ELECTRICAL SHOCK AREA! USE CAUTION!
1. Make sure power is being supplied to the
freezer and that all operating switches are in
the correct position.
2. Using a voltmeter, check the voltage supply to
the thermistor control. The control requires 24
volts to operate.
3. Using an ohmmeter, check probe resistance.
(Refer to the thermistor curve chart on page 14
for proper readings.)
If the thermistor relay which deactivates the
compressor will not open, check the following items:
ELECTRICAL SHOCK AREA! USE CAUTION!
1. Make sure the thermistor relay opens when the
freezer control switch is in the “OFF” position.
2. Make sure the thermistor probe is connected to
the correct probe terminals.
3. Using an ohmmeter, check the thermistor probe
for proper resistance. (Refer to the thermistor
curve chart on page 14 for proper readings.)
4. Disconnect one wire to an anticipator terminal.
If the thermistor relay opens after
approximately 25 seconds, the problem is in the
anticipator wiring circuit.
When problems such as erratic product quality
occur, it is of utmost importance to determine if the
thermistor components are defective before
replacing them.
For a diagram of the thermistor control, see
page 18 (Troubleshooting Thermistor
Components).

When checking a thermistor probe, first determine the temperature at the probe and find it on this chart, along with the correct
ohmmeter reading. If your ohmmeter reading varies from the correct reading, determine whether the difference is acceptable. If
a probe is faulty, the difference will be great.

Maintaining Quality
Operation Tips
To achieve the highest quality product, the following
are key operation procedures:
1. The machine should be primed with 2 gallons
(7.6 liters) of fresh mix. Rerun should be added
to the machine only before a rush period. One
part rerun mix should be mixed with two parts
fresh mix. Always skim the foam off the top of
the rerun. In addition, make certain that all
rerun is completely liquid before use; frozen
particles in the mix may plug the feed
assembly. To minimize beating time, start the
machine as close to opening time as possible.
2. Freeze down will take approximately 7 minutes.
Afterwards, the product should be 20_F
(-6.7_C) ±1_.
3. It is possible to “outdraw” this unit. If the unit is
outdrawn, it should be given a chance to
recover, or inferior product will be served.
Outdrawing the unit can starve the cylinder of
mix and can cause mechanical damage.
Always make certain there is mix in the hopper.
4. If the unit is air cooled, the condenser must be
kept clean. A clogged condenser will result in
excessively long run times. The condenser
should be inspected regularly and brushed
clean when dirty.
5. Sharp and proper size scraper blades are of
critical importance. If the blades are nicked or
worn, they must be replaced, or poor scraping
and inefficient freezer operation will result.
6. O-rings and plastic scraper blades should be
replaced every three months. If at any time the
scraper blades are worn to less than 15/16”,
they should be replaced.
