Fig. 9: Filling installed unit (via inlet
connection)
CAUTION
If the installed unit is run dry, the mechanical
seal will be destroyed in a matter of seconds!
DO NOT switch on until the following
conditions are met:
 The separator must be correctly filled with
operating liquid.
 The interior of the installed unit must be
filled with operating liquid.
 WARNING
Danger due to escaping fluid!
Make sure that all openings in the separator
(feed/drain regulator connection, fill opening,
drain opening) are tightly closed (by means of
screwed-in bung plugs or installed feed
regulator, drain regulator and drain valve)
when the separator is filled with operating
liquid.
5.4 Connection of pipes/hoses
 WARNING
Danger from vacuum!
Do not operate the unit unless the pipe / hose
has been fitted to the inlet connection!
If there is a danger that the system could suck
in:
 Do not go near the inlet connection with
long, open hair or loose fitting clothing,
 Do not look into the inlet connection or
move your eyes in front of the inlet
connection opening.
 WARNING
Danger from vacuum!
Danger due to escaping fluid!
During operation connected pipes and vessels
are vacuumised!
Make sure that all connections are sufficiently
tight! Use only pipes and vessels of sufficient
strength!
The pumped gases/vapours are sucked in via
the inlet connection (see Chapter 5.4.1, Pg. 18)
and discharged via the exhaust-air connection
(see Chapter 5.4.2, Pg. 19).
5.4.1 Inlet
connection
Remove sealing plug
To prevent the penetration of foreign bodies, the
connection opening on the inlet connection
(Item A) is sealed off on delivery.
Do not remove the sealing plug until immediately
before connecting the pipes/hoses.
Check valve:
In the following cases a check valve must be
attached to the inlet connection (Item A):
 If two or more systems are operated in
parallel, e.g. reserve system.
(Note: A separate check valve must be
attached to the inlet connection on each
system.)
 If a vacuum can occur for more than
one minute in the connected intake line on the
system switched off.
The check valve prevents the backflow of
pumped gases/vapours from the system during
an interruption in operation.
