Push this button, prior to compressor start ---up, to allow the
engine to warm---up for easy starting.
Continually monitors the pressure inside the receiver sump
at various load and unload conditions.
Indicates the accumulated hours of operation. Useful for

Monitors the fluid level in the sump. Proper level is visible
halfway up the sight glass. Check the level when the com-
pressor is shut down and on level ground.
Opens the electrical circuit to shut down the compres---
sor when the discharge temperature reaches a specific
value (see Section 3, Specifications).
Functions as a temperature regulator directing the com-
pressor fluid either to the cooler or to the compressor unit.
Maintains the minimum of 85 psig (5.9 bar) in the compres-
sor sump.
Opens sump pressure to the atmosphere should pressure
inside the sump exceed 200 psig (13.8 bar) .
Regulates the amount of air allowed to enter the air inlet
valve. This regulation is determined by a pressure signal
from the pressure regulator.
Allows a pressure signal to reach the engine speed control
cylinder and the air inlet valve to control air delivery accord-
ing to demand.
down conditions. The annunciator module on the instru-
