8 OPERATION AND ROUTINE MAINTENANCE
8.1 OPERATION AND GENERAL MAINTENANCE
The commissioning procedure should be used:–
(a) For the first commissioning run
(b) Following overhaul
(c) After standing idle for an extended period
External cleanliness of the compressor pipework and jointing is imperative in order that any leakages
may be readily detected. Monitor and record stage pressures and temperatures in order to give
advanced warning of any malfunction. Ambient conditions, especially temperatures, will vary readings but
they are usually within plus or minus 4%.
Marking the pressure gauge glass at the normal running pressure will allow easy comparisons of
pressure to be made.
8.2 STARTING UP
Ensure operator is fully conversant with controls and safety devices.
Check oil level in crankcase and top up, using recommended oil if necessary, until sight glass is three
quarters full.
Set stop valves in control pipework correctly.
Ensure trip circuits, if fitted, are correctly set.
Check V belts are in good condition and correctly tensioned.
Check that compressor and ancillary equipment are clear of all loose equipment and tools.
Ensure that there is adequate water in the cooling system (radiator sets) or supply from the mains.
Operate main control or motor starting gear.
8.3 RUNNING ON LOAD
Set automatic timer (when fitted) to vent diaphragm drain valves every 30 minutes for 5 seconds
duration, or more frequently if high humidity prevails.
Monitor gauges for normal pressures and temperatures.
Check water temperature rise 10°C to 12°C across machine and adjust to suit.
Observe compressor is functioning correctly without undue vibration or noise.
8.4 STOPPING
Stop compressor by depressing stop button on motor control panel. Turn off cooling water flow if no
automatic water valve or water pump is fitted. The machine will automatically unload via unloader
system.
8.5 STANDING IDLE
The unloaders will automatically be left open.
For ambient temperatures below 0°C protect machine by draining off cooling water system, unless
protected by anti-freeze.
After one week standing idle, turn the machine over by hand before starting to ensure it turns freely.
If the compressor is to stand idle for more than four weeks, or shorter period if ambient conditions are
unfavourable, it is advised to consult Reavell for correct inhibition procedure.
