Running Specifications
Pressures/Temperatures
The following are the
Taylor Company
recommended
settings for various components within these models. All
freezers in this manual use Refrigerant HP62 (R404A).
Expansion Valve Soft
Serve
Air Cooled - 21 psi. (145 kPa)
Water Cooled - 20 to 22 psi. (138 to 152 kPa) for a
normal product of 16° to 18°F. (-8.8°to -7.7° C.).
Expansion Valve Adjustment
Place your gauge on the access valve on the suction line
(located at the compressor).
Adjust the pressure higher or lower by turning the
adjustment screw. Clockwise turns will raise the pressure
and counterclockwise turns will 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.
Important:
On the Models 336 and 338, expansion
valves on each side of the unit must be set separately.
Pressures must be set at 4 PSI (28 kPa) lower than what
is indicated on the tag.
Low Side (Suction)
Suction pressure equals the expansion valve
setting.
High Side (Discharge)
High side pressure varies for air cooled units, depending
on the ambient temperature.

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