Putting into operation
Please check all parts for damage when unpacking. It is
important that any transport damage be discovered when
the parts are unpacked. If necessary, a record of the
condition of the parts should be made immediately (report
to postal service, railway service, or shipping company).
Keep the original packaging for the event of a later transport.
4.1
Placement
The device must be set up on a stable, clean, and level
surface. The surrounding temperature may not exceed 40°
C. Proper air circulation is necessary.
The device must be placed at a minimum of 20 cm from
walls and other objects in order to prevent damage. Con-
tainers, chemicals, or other devices may not be placed
behind the pump.
4.2
Connections
4.2.1 Electrical connections
Ensure that the electric current available from the location’s
outlets is the same voltage as that indicated by the label
on the apparatus. The device must always be connected
to a grounded outlet. External couplings and extension cords
must have a protective conductor (3-pin couplings, cables,
or plug and socket connections). There must be no break
in any part of the protective conductor. This will avoid risks
resulting from internal defects.
Connect the pump to the power source with the enclosed
cable.
4.2.2 Other connections
Before putting the device into operation, the screw caps
on the connections must be replaced by GL-14 connections
or sound absorbers.
Please be sure that none of the hoses are bent closed
(bends, the device is resting on the hose).
Replace brittle hoses.
The hoses should be secured with standard hose clamps
or cable binders for safety.
The device must never be put into operation without an
exhaust hose. The exhaust hose must not be pointed
towards hot objects or towards objects which produce
sparks.
The exhaust hose must end in a fume hood so that none of
the vapors from the solvents can be released in the room.
