probe is located at the separator discharge and senses
the temperature of the air at the oil separator.
The microprocessor controller will shut the compressor
down if the temperature sensed at either location ex-

Damage will occur to the machine if it
is repeatedly restarted after high tem-
perature stops operation. Find and
correct the malfunction before re-
suming operation.
Relief Valve – A pressure relief valve(s) is (are)
installed in the final discharge line and set at the factory
to approximately 120% of the unit’s full load operating
pressure for protection against overpressure. Periodic
checks should be made to insure that it is operating
properly.
The relief valve should be tested for proper operation
at least once every year. To test the relief valve, raise
the system operating pressure to 75% of the relief valve
set pressure and manually open the valve with the hand
lever. Hold the valve open for a few seconds and allow
it to snap shut.
When the relief valve opens, a stream
of high velocity air is released, result-
ing in a high noise level and possible
discharge of accumulated dirt or oth-
er debris. Always wear eye and ear
protection and stand clear of the dis-
charge port when testing the relief
valve to prevent injury.
Never paint, lubricate or alter a relief
valve. Do not plug vent or restrict dis-
charge.
Operation of the unit with improper
relief valve setting can result in se-
vere personal injury or machine dam-
age.
Insure properly set valves are
installed and maintained.
