1 Blow Down Valve
.
To prevent foaming or sudden
release of pressure, allow 10
minutes after shutdown before
opening the compressor oil dip-
stick/fill cap or performing other
compressor maintenance.
To control the release of air mixed in
the compressor oil (while running),
the compressor goes through a
blow down cycle when the com-
pressor is turned off or the engine is
stopped. The blow down valve
slowly discharges the pressure in
the compressor.

passed when ambient temperature
