8.4 MAINTENANCE & REPAIR PRECAUTIONS
Maintenance, repair and modifications must only be carried out by competent persons under a
“PERMIT TO WORK” system..
Pressure gauges, temperature switches and other protection devices should be checked at least every
12 months and thoroughly examined at least every 48 months. They must be renewed or service
exchanged if acceptable tolerances are exceeded or if they are not functioning correctly.
Before dismantling any part of the compressor close, and lock if possible, the isolating valves upstream
and downstream of the compr
essor system’s air, gas and water supplies as appropriate.
Check that all pressure gauges register zero and that all air or gas pressure in the system has been
released.
Before dismantling any part of the compressor, ensure that all heavy movable parts are secure.
Oil lubricated compressor will have preserving oil applied to interior surfaces. Oil free models will have
desiccant bags in valve covers and distance pieces which must be removed prior to start-up.
Protect components and exposed openings by covering with clean cloths or tape during repair or
maintenance work.
Protect all items as necessary against the ingress of moisture if steam cleaning is undertaken.
On completion of any maintenance or repair ensure that no tools, loose items or rags etc., are left on
or inside the compressor or other parts of the system.
Always clean oil spills from the compressor module before and after maintenance work.
Viton Seals

Viton ‘O’ seals under normal operating conditions are safe.

However, should there be a fire within the compressor or these seals are likely to exceed a
temperature of 300°C the material will decompose.

Degraded Viton gives off Hydrogen Fluoride fumes and if in contact with skin an
acid is formed causing severe burns
.

If Viton seals appear charred or gummy do not touch with unprotected hands: wear
neoprene or PVC gloves.

When the seal has been removed, wash the area with limewater and avoid breathing any
fumes. If contamination of the skin occurs, wash with limewater and seek medical advice.
8.5 PRECAUTIONS IN THE EVENT OF FIRE WITHIN THE COMPRESSOR
Use extreme caution when handling components that have been subjected to fire or very high
temperature. Some components may contain fluoroelastomer materials which decompose under these
conditions to form highly corrosive residues. Skin contact can cause painful and penetrating burns
resulting in permanent skin and tissue damage.
