Section Iv - Operating Procedures; Prior To Starting; Starting The Compressor - Quincy QSF Series Instruction Manual

Section I V– Operating Procedures
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.

Prior to Starting

Before starting the unit, review Sections II and III of this manual and be certain that all installation
requirements have been met and that the purpose and use of each of the controls, warnings are
thoroughly understood. The following checklist shall be adhered to before placing the compressor into
operation:
Remove all loose items and tools from around the compressor installation.
•
Check fluid level in the air/fluid reservoir. See Lubrication 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.
•
After all the above conditions have been satisfied, close the main power disconnect switch, jog the
starter switch button to check the rotational direction of the compressor. The compressor must
rotate counter-clockwise when facing the compressor from the shaft end. Check the fan rotation, air
flows through the coolers.
•
Water-cooled models - Check inlet and discharge water piping for proper connections.
NOTE: The water temperature-regulating valve is located in the discharge water line.
NOTE:
Please read detailed instructions in Section III prior to startup. Failure to follow instructions may
void the warranty.

Starting the 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 VII. Never increase air pressure
settings beyond factory specifications.
•
Adjust the water temperature regulating valve to maintain 180
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.
