11 FAULT GUIDE
IMPORTANT
THE WORK DETAILED IN THE FOLLOWING
GUIDE MUST ONLY BE UNDERTAKEN BY
SUITABLY TRAINED AND QUALIFIED PERSONEL.
WARNING
BEFORE PROCEEDING WITH ANY MAINTENANCE ON THE COMPRESSOR IT
MUST BE STOPPED ISOLATED ELECTRICALLY AND MECHANICALLY,
COMPRESSOR GAS INLET AND OUTLET VALVES CLOSED AND VISIBLE
WARNING NOTICES DISPLAYED.
IN ADDITION ALL INTERNAL PRESSURE MUST BE RELEASED WITH THE UNIT
ISOLATED FROM THE STORAGE RESERVOIR AND THE WATER SUPPLY SHUT
OFF.
NOTE: A safety valve opening indicates excessive pressure and under NO
CIRCUMSTANCES must a safety valve be screwed down to accommodate
excessive pressure. THIS IS DANGEROUS. If safety valve opens or appears faulty
shut down compressor immediately and investigate.
If fault appears immediately or shortly after a service, first examine those parts
disturbed during the service.
The following is a list covering the probably causes of operational faults, together with the suggested
remedies.
The list covers a range of compressors and modes of operation, therefore not all of the faults will be
applicable to any particular installation.
Before investigating a potential fault, ensure however that:
Cooling water temperature, temperature rise across the machine, and flow rate are correct.
Direction of rotation is correct.
Sump is correctly filled.
Compressor servicing is up to date.
Power supply is correct.
If fault appears immediately or shortly after a service, first examine those parts disturbed during the
service.
