B. Condensate enters the reservoir (1) through the inlet port.
When the condensate level in the reservoir covers the
capacitance sensor, an electronic signal is sent to the solid
state countdown processor. The processor delays the
opening of the solenoid valve for a given period of time.
Once the time has elapsed, the solid state processor
transmits information to energize the coil in the solenoid
valve (2). The magnetic force of the coil causes the
solenoid core (3) to move, closing the pilot air supply line
and opening the pilot air exhaust line. After the pilot air
above the diaphragm (4) is vented, pressure in the reser-
voir opens the discharge port and forces the condensate
through the discharge port and outlet piping.

2.0 OPERATION
2.1 Minimum/Maximum operating conditions
A. Maximum inlet air pressure: refer to dryer serial number
tag
B. Minimum inlet air pressure: 30 psig (2.1 kgf/cm
C. Maximum inlet air temperature: 120°F (49°C)
D. Maximum ambient temperature:
Air-cooled models: 110°F (43°C)
Water-cooled models: 130°F (54°C)
E. Minimum ambient temperature: 45°F (7°C)
2.2 Start-up
A. Models 100-150:
Energize compressor by positioning the on/off switch in
the on (I) position. Compressor on light will illuminate.
On/Off Switch Power-On Light
B. Models 200-750:
Energize dryer. Green power on light will illuminate.
IMPORTANT: Energize dryer disconnect switch (provided
by others, see NEC) 24 hours before refrigeration com-
pressor is started! Never use the disconnect switch to
shutdown the dryer for a extended period of time (except
for repair). Failure to follow these instructions may result
in a non-warrantable compressor failure.
NOTE: If there is no power to the control board for a
period of two weeks or more, it may return to the default
mode.

NOTE: On dryers with air-cooled condensers, regular
condenser cleaning is recommended. Dirtiness of
ambient air at installation site will determine frequency
of service. Typically once a month is recommended.
Dryers contain an integral 3 micron filter. As the filter
element accumulates solid contaminants, differential
