Electric power always exists inside the pressure switch when there is electric
power at the compressor package. Either a qualified electrician should make the
pressure adjustments or the electric power supply should be disconnected and
locked out before making any adjustment.
NEVER exceed the designed pressure for the system or overload the motor be-
yond its service factor.
FAILURE TO HEED THESE WARNINGS MAY RESULT IN SERIOUS INJURY OR DEATH,
PROPERTY DAMAGE AND/OR MECHANICAL FAILURE
Relieve compressor and system air pressure by opening the appropriate manual
relief valve prior to servicing. Failure to relieve all system pressure may result in
severe personal injury, death and property damage.

PRESSURE SWITCH
The pressure switch is automatic in operation and is adjusted to start and stop the unit at the minimum
and maximum desired air receiver pressure by cutting in and out the power to the electric motor. On some
models, the pressure switch incorporates a release valve, which releases air between the check valve locat-
ed in the receiver and discharge valve in the head of the compressor.
MANUAL RELIEF AND SHUTOFF VALVES
Install a manual relief valve to vent the compressor to atmosphere. In those instances where the air receiver
tank services a single compressor, the manual relief valve can be installed on the receiver. When a manual
shut- off valve, and a safety relief valve installed upstream from the manual relief valve. These valves are
to be designed and installed as to permit maintenance to be performed in a safe manner. Never substitute
a check valve for a manual shut-off valve (block valve) if the purpose is to isolate the compressor from a
system for servicing.
