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 located 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.
CAUTION
CAUTION

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.

CAUTION
!
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 beyond its service factor.
