Maintenance

Although QED usually does not supply the compressor, this section is provided to help the
operator. If the system receives clean, oil-free air from the compressor, maintenance will be
significantly reduced.
Inspection - Check for possible damage in transit. Almost all compressors are shipped with
the flywheel unmounted. Do not force the flywheel on the crankshaft. Use a wedge-in "slot"
provided for easy assembly. Checked belt alignment and tension carefully.
Placement - A compressor is a source of sparking. Place it out of what is considered a
hazardous area by local and national fire and electric codes.
Mounting - Install in a clean, dry, well-ventilated location away from any source of heat such
as a boiler or radiator. If the unit is to be fastened to a foundation, support and shim all four
feet firmly to remove all stress from the unit. The compressor flywheel should be mounted
towards a wall with a minimum clearance of 18 inches to allow for circulation of air and
additional clearance if required for servicing.
Lubrication - Fill the crankcase to the level mark on the oil gauge. Use the type of industrial
compressor oil that is recommended by the manufacturer for the ambient temperature. Do not
use synthetic oil, as these can damage the pumps.
Pressure and Speed - Never operate the compressor at pressures or speeds in excess of those
recommended by the factory. Every compressor assembly must have a safety valve installed
and should be set at either the maximum tank working pressure or 25 psi over the actual
pressure of the pump, whichever is less.
Daily - Check for unusual noise, failure to compress, overheating, oil leaks, and vibration.
Correct before serious damage can develop. Drain all condensate from receiver and traps.
Weekly - Examine intake filter elements and if they are dirty, remove and clean or replace
them. Check oil level and add oil if necessary. Do not fill over level mark on sight glass.
Keep compressor clean for efficient operation and appearance.
Monthly - Check and tighten all bolts and nuts as required. Check air connections for air
leaks and tighten as required. Check belt tension.
