Checking the oil level
‣
Check that the oil reaches the oil inspection glass
(2).
‣
Correct the oil level as needed.
If the oil level is too high (oil inspection glass
is completely full):
‣
Unscrew and remove the locking screw (1) from
the compressor housing. The oil flows out of the
threaded hole (4).
‣
Catch the oil and dispose of it according to the
legal regulations.
If the oil level is too low (no or very little oil is
visible in the oil inspection glass):
‣
Unscrew and remove the locking screw (1) from
the compressor housing.
‣
Top up the oil. To do so, unscrew the cap (3) and slowly pour oil in until the oil reaches the lower edge
of the threaded hole (4). Alternatively, pour the oil into the compressor housing through the threaded
hole with the help of a hose.
CAUTION
ENVIRONMENTAL POLLUTION THROUGH OIL!
Very small quantities of oil are sufficient to make significant amounts of potable water unusable.
‣
During the oil change, make sure that no oil is released into the environment.
‣
Dispose of the used oil in accordance with local regulations.
NOTICE
DAMAGE DUE TO INCORRECT OILS!
Incorrect oils can destroy the compressor.
‣
Only use specified oil (chapter 1.9 on page 10).
NOTICE
INCORRECT OIL LEVEL!
If the oil level is insufficient, significant tangible damage can occur. If the oil level is excessive, foam‑
ing and, thus, oil leakage can occur.
‣
Observe the fill quantity.
‣
Screw the locking screw back in.
