Running Specifications

Pressures/Temperatures
The following are the Taylor recommended settings
for various components within these models. The
freezers in this manual use refrigerant R404A.
Expansion Valve (AXV)
Air Cooled - 21 psi (145 kPa)
Water Cooled - 21 psi (145 kPa)
for a normal product of 16° to 18°F (‐8.8° to ‐7.7°C).
Expansion Valve Adjustment (AXV)
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 raise the
pressure and counterclockwise turns 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.

Introduction
Low Side (Suction)
Suction pressure equals expansion valve setting.
High Side (Discharge)
High side pressure varies for air cooled units,
depending on the ambient temperature.
Ambient Temperature
F C
70° 21.1°
80° 26.7°
90° 32.2°
100° 37.8°
Water Valve
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.
