Warning notes
DANGER
Voltage > 42 V
Direct contact with live parts may cause serious
injury or death.
Before working at electric equipment, interrupt the
power supply (turn off main switch, remove fuses or
switch them off).
WARNING
Lines under pressure bear a risk of injury.
Before taking up the work, check compressed air
lines and make sure that they are not under pressure.
WARNING
The oil separator operates with an eccentric spiral
pump. Do not put your hands to the rotating shaft in
the area of the transmission bell housing / stuffing
box packing! Danger of severe finger injury.
WARNING
The valves pos. 4, 5 and 15, up to rated width R 1",
are closed by means of a pre-tensioned spring. On
dismounting the valve drive, the spring can eject
forcefully and cause injuries.
CAUTION
The oil separator can be heated by a heater
(electrically or e.g. by steam). In the upper area,
temperatures up to approx. 50 degrees Celsius can
occur. Danger of burns.

Table of faults
Fault
Reason
Remedy
Permanent repetition of the
flushing process in short
intervals
The system draws air from the
empty bilge
No switchoff by level switch in
bilge
Switch off the system!
Check the level switch
Permanent repetition of the
flushing process and
pressure vacuum gauge
shows insufficient suction
height as compared to
installation level.
The system draws air due to
leaks in the course of the suction
line or possibly at the oil
separator (cover, flanges, valves)
Lift off system and
suction line, remove
leakage.
Low delivery power at high
vacuum display
The suction line or the rough filter
at the inlet are jammed
Clean suction line
and/or rough filter
Valve closed in suction direction Open valves
