Recommended Operation and
Maintenance for the Particle Strainer
The particle strainer should be cleaned
once every week or as needed.
1) Close the shut-off valve on the
particle strainer.
2) Depressurize the drain by pressing
the drain PRESS TO TEST on DRAIN
TEST key.
3) Unscrew bottom of the particle
strainer and clean the screen.
Caution!
Failure to depressurize may cause
bodily injury.
Compressor
Refrigerant compressors normally do not
need any maintenance. The compressor
will unload or adjust for different load
conditions with the refrigeration controls.
Any time power is applied to the
compressor, and the suction pressure is
higher than the specified readings, the
compressor is either not pumping or
failed electrically, or tripped "off" at the
overload protection. If the compressor
does not automatically reset within a few
minutes, it requires servicing. Service must
be performed by a qualified refrigeration
technician.
Dual Pressure Switch
This safety switch protects the refrigeration
system. If the refrigerant pressure falls
below or above the normal operating
range, this switch trips the compressor.
Manually reset the switch after rectifying
the fault to run the dryer again.
Section V - Integrated Dryer (option)
Expansion Valve
Integrated air dryers are equipped with
a thermostatic expansion valve, factory
set to maintain a superheat of 8 to 10°F.
These valves do not need adjustment in
normal operation. Generally, superheat
adjustments are needed only at the time
of valve replacement. Expansion valve
service must be performed by a qualified
refrigeration technician
