Operation

This compressor has been
inspected, thoroughly tested
and approved at the factory.
For this unit to give long
satisfactory service it must be
installed and operated properly.
This compressor has been designed
for a 80%/ ON – 20%/ OFF duty
cycle.
Simplex units have a pressure
switch that senses changes in
receiver pressure and
automatically starts and stops
the compressor at preset
pressure limits.
Duplex units have pressure
switches and an automatic
alternating system to evenly
distribute the load between
the two compressors. If the
receiver pressure drops below
135 PSI, both compressors run
until receiver pressure reaches
175 PSI. If the pressure in the
receiver drops below 145 PSI,

Specifications" Section.
NOTE: Do not mix oil
type, weights or brands.
3. Inspect unit for any visible
signs of damage that would
have occurred in shipment
or during installation.
Plant air piping should be
periodically inspected for leaks using
a soap and water solution for
detection on all pipe joints. Air leaks
waste energy and are expensive.
