Oil Change (Oil Separator Tank and Oil Cooler)

For type of oil and frequency of oil change see chapter 1.8
Oil change must be carried out with warm to the touch condition of the compressor pack-
age (Oil temperature approx. 104•F).
If the compressor package operates in ambient temperatures close to the maximum ambi-
ent temperature (see chapter 1.6), change the oil more often (e.g. 1/2 or 1/4 of recom-
mended interval).
Attention!
Attention!
 Stop the compressor package under full load (see chapter 8.3).

Maintenance
Danger of scalding with hot oil.
When inserting the maintenance hose into the compressor's hose
couplings, always have the ball valve closed and the hose end se-
cured before slowly opening the ball valve. Beware of air/oil mist that
could blow out of the hose. Unrestricted air/oil flow through the hose
end will result in a whipping action which could cause severe injury or
death.
Drain the oil out of the oil separator tank, cooler and the oil pipes com-
pletely. See chapter 9.14.4 for putting back into operation.
If a heat recovery system is fitted drain all the oil in the heat exchanger
during the oil change.
Lock the main disconnect in the "off" position in accordance with ap-
plicable lock out/tag out procedures (example: OSHA CFR 29
§ 1910.147) to ensure the compressor does not restart.
