Prior to Starting
CAUTION!
Provisions should be made to have the instruction
manual readily available to the operator and
maintenance personnel. If, for any reason, any
parts of the manual become illegible or if the
manual is lost, have it replaced immediately. The
instruction manual should be read periodically
to refresh one's memory. This may prevent a
serious accident.
Before starting the compressor, review Sections II and III
of this manual. Be certain that all installation
requirements have been met and that the purpose and use
of the controls are thoroughly understood. Before
placing the compressor into operation, do the following:
• Remove all loose items and tools from around the
compressor.
• Check fluid level in the air/fluid reservoir. See
Compressor Fluid Section.
• Check the fan and fan mounting for tightness.
• Manually rotate the compressor through enough
revolutions to be certain there are no mechanical
interferences.
• Check all pressure connections for tightness.
• Check to make sure all relief valves are in place.
• Check to make sure all panels and guards are in
place and securely mounted.
• Check fuses, circuit breakers and thermal overloads
for proper size.

• Close the main power disconnect switch and jog the
starter switch button to check the rotational direction
of the compressor.
• Check the fan rotation (air flows through the
coolers).
• Water-cooled models - Check inlet and discharge
water piping for proper connections.
Starting the Compressor
• Secure all enclosure panels on compressor.
• Open the service valve to the plant air distribution
system.
• Select the mode of operation and start the
compressor.
• Watch for excessive vibration, unusual noises or air/
fluid leaks. If anything unusual develops, stop the
compressor immediately and correct the condition.
• Control settings have been adjusted at the factory;
however, they should be checked during start-up and
readjusted, if necessary. Some applications may
require a slightly different setting than those
provided by the factory. Refer to the Service
Adjustment Section VIII. Never increase air
pressure settings beyond factory specifications.
• Adjust the water temperature regulating valve to
maintain 180°F discharge air temperature (water-
cooled units only).
• Observe compressor operation closely for the first
hour of operation and frequently for the next seven
hours. Stop and correct any noted problems.
