Q control
3.1 Prior to Starting
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, ensure 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.
Check the fan and fan mounting for tightness.
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. Reset overloads, if needed.
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.
3.2 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. Never increase air pressure settings beyond factory specifications.
Observe compressor operation closely for the first hour of operation and frequently for the next seven
hours. Stop and correct any noted problems.
Stopping the Compressor
Normal Operation
Close the service valve to the plant air distribution system. Allow the pressure to build within the reservoir and
the compressor to fully unload. Press the stop button or remove power at the main disconnect switch or panel.
