SECTION 11

PRESSURE RELIEF VALVE

Pressure Relief Valve - This device protects the pressure-containing components of the compressor

package against pressures exceeding 188.5 psig. It is installed on the dry-side of the oil sump.

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.
