Product Manual

2.4
General functional description
The operator must follow the safe working practices,
instructions, procedures that this manual describes for
safe operation. The maintenance personnel must be
adequately trained, and have read and thoroughly
understood this ‘Operation and maintenance manual’.
Decals are affixed at specific locations of the compressor
and they illustrate very important safety precautions.
2.3.1 Precautions during installation
 Ensure that you fasten all loose parts before lifting. Select
the appropriate lifting equipment by considering the local
safety regulations, size and weight of the compressor.
Operate the lifting equipment carefully within the safe
operating limits. Ensure all necessary personal protective
equipment's (PPEs) is close at hand during this operation.
 Maintain a cool and clean ambient for the compressor
and ensure that the air inlet is not obstructed. Make
arrangements to reduce the moisture entry through the
incoming air.
 Remove protection such as caps, plugs, desiccant bags
before connecting the air line pipes.
 Remove the red colored protective clamps from the
airend and motor while commissioning the compressor.
 Do not use frayed, damaged or worn hoses. Distribution
pipes and connections must be of the correct size and
suitable for working pressure.
 Make sure that the aspirated air by the compressor is
free of flammable fumes, vapors and particles, to
prevent internal fire or explosion.
 For remotely controlled compressors and auto-start
compressors, provide a clear caution stating:
“DANGER” – Remotely controlled machine and will
start without notice
 Ensure the operator is located far away from the intake
of the compressor.
 Position the after-cooler discharge pipe in a way that it
is free to expand under heat and is not in contact with
or close to flammable materials.
 Do not exert external force on the air outlet valve and
keep the connected pipe always free of strain.
 Make available adequate cooling air must be made
available for the compressor particularly air cooled
compressors. Make sure that exhausted air does not
circulate back to the intake or cooling system.
 Make the electrical connections according to the legal
standards and earth the compressor suitably. Provide a
sufficient number of fuses and other protective devices
to protect the compressor against short circuits. Good
practice is to provide an isolating switch nearby the
compressor.
 Install manual valves behind non-return valves (NRV) to
isolate each compressor in multi-compressor systems.
Do not rely on NRV for isolating pressure systems.
 Do not bypass, remove or adjust the safety devices or
other attachments residing on the compressor. Every
installed pressure vessel or auxiliary outside the
compressor should have pressure relieving device or
devices, as required.
 Danger! Be aware that compressed air used for
breathing or food processing must meet O.S.H.A.
