Differential Pilot Valve

WARNING!

Never adjust the pressure higher than the factory
setting. Death or serious injury and compressor
or property damage could result.

Open a manual vent valve to allow the compressor to
exhaust air to the outside and start the unit. By manual
regulation, slowly close the valve, allowing the unit to
build air pressure to the desired modulation point and
hold (110 PSIG standard). Adjust the screw on the
bottom of the differential pilot valve so that a slight
stream of air can be felt coming from the orifice adjacent
to the adjustment screw.

When this air is felt, air is beginning to pass through the
pilot valve to the air cylinder on the inlet valve, causing
the valve to modulate toward its closed position, thereby
reducing the volume of air being compressed.

To raise the pressure, turn the adjusting screw in
(clockwise). To lower the pressure, turn the screw out
(counter clockwise). Maximum full load pressure is 110
PSIG for standard QSI units. Minimum full load pressure
with modulation and standard controls is 75 PSIG.

Pressure Switch

The pressure switch determines what pressure the
compressor will load and unload. Standard factory
settings are 110 PSIG cut-in, 125 cut-out. If a lower
setting is desired, adjust the differential pilot valve first
and set the pressure switch cut-out point to 15 PSIG over
the desired full load pressure. The range adjustment is
made by turning the screw clockwise to increase the cut-
in/cut out pressure.

Water Temperature Regulating Valve
(Water-cooled units Only)

The water temperature regulating valve senses fluid
temperature and opens or closes, regulating water flow
from the unit. It is factory set to maintain 180°F
discharge temperature. Due to different incoming water
temperatures and/or pressures at each location valve
adjustment should be checked during start-up to maintain
180°F discharge temperature. To increase fluid
temperature, decrease water flow by turning the
adjustment screw clockwise. To decrease fluid
temperature, increase water flow by turning the
adjustment screw counter clockwise.
