Before inspecting the pressure relief valve, release air pressure, lockout and
tagout the power supply to the compressor package. Failure to release
pressure or properly disconnect the power may result in personal injury or
death.
Never paint, lubricate or alter a relief valve. Do not plug vent or restrict.
Operation of the unit with improper relief valve setting can result in severe
personal injury or machine damage. Ensure properly set valves are installed
and maintained.
Pressure Relief Valve Inspection –
The pressure relief valve has no user-serviceable or repairable
components. However, it should be tested for proper operation at least once every year. To test the
relief valve, raise the system operating pressure to its normal level and manually open the valve with the
hand lever. Hold the valve open for a few seconds and allow it to snap shut.
