CONDENSATE DRAIN PIPING AND COLLECTOR
The outlet opening of the condensate drain manifold is con
nected to a condensate drain separator. It separates the con
densate from the air escaping together with the condensate
from the filters. The air passes through a silencer and is re
leased into the open air, the condensate is collected in a con
densate tank. An additional silencer is mounted on top of the
tank. The condensate tank should be emptied at regular in
tervals. The maximum condensate level is marked with a
black line.
Due care must be taken to ensure that any oil which may be
drained with the condensate will not pollute the environ
ment. For example, the drain pipe can be directed into a col
lecting vessel or into drain facilities incorporating oil separ
ators.
Dispose of condensate according to local
regulations!
MAINTENANCE
The condensate drain valve for the oil and water separator
is fitted with a manual drain tap to check correct operation
of the automatic system.
- Open the manual drain valves (3, Abb. 56) once a week.
This must be carried out immediately after the automatic sys
tem has drained the condensate. Observe the drainage of
condensate when opening the manual drain valves. If the
system drains a lot of condensate this is a sign that the system
or the corresponding condensate drain valves are not work
ing properly or that condensate drain intervals are to long.
Find the fault and remedy accordingly. If hardly any conden
sate emerges, the automatic system is operating properly. For
fault correction, see also chapter 4.6. ”Trouble-shooting”.
Maintenance of the condensate separator
The condensate separator elements must be replaced reg
ularly according to the maintenance schedule. Proceed as
follows:
- Press the lock button on the ring (1), unlock the ring and
remove it.
- Remove container (2).
- Remove the self-locking nut (3), the metal cover (4) and
the element (5).
- Unscrew the deflector (8).
- Remove element (9).
- Remove O-ring (10).
Reinstallation:
- Insert a new filter element (5).
- Replace the metal cover (4) and secure it with the self-
locking nut (3).
- Lubricate an O-ring (10) from the repair kit and place it on
the container.
- Insert a new filter element (9) and hand-tighten the de
flector (8).
- Replace the container (2) and secure it with the ring (1).
