5 Commissioning
 WARNING
Improper use of the pump−motor unit can
result in serious or even fatal injuries!
Have you read the chapter "Safety
instructions"? (
 5)
Otherwise you may not carry out any work with
or on the pump−motor unit!
 WARNING
Danger from rotating parts (motor fan,
impeller, shaft): cutting/cutting off of
extremities, grasping/winding up of hair and
clothing!
Danger due to vacuum and gauge pressure:
sudden escape of media (skin and eye
injuries), sudden drawing−in of hair and
clothing!
Danger due to escaping media: burns!
Commissioning and operation only under the
following conditions:
 The pump−motor unit must be completely
assembled. When doing so, pay particular
attention to the following components:
–
the cover of the gas ring blower housing,
– the mufflers on inlet and discharge
connections,
– the fan guard.
 The pipes/hoses must be connected to inlet
and discharge connections.
 Inlet and discharge connections and the
connected pipes/hoses may not be closed,
clogged or soiled.
 Check the mounting elements, connections
of the pipe/hose connections, lines, fittings
and containers for strength, leaks and firm
seating at regular intervals.
5.1 Preparation
 WARNING
Danger from closed connections!
With closed/soiled inlet or discharge
connections vacuum or gauge pressure results
in the pump−motor unit.
This can overheat and damage the drive motor
winding.
Before commissioning, make sure that the inlet
and discharge connections are not closed,
clogged or soiled!
CAUTION
Before starting up again after a longer
standstill:
 Measure the insulation resistance of the
motor.
 With values < 1 k /Volt of rated voltage,
the winding is to dry.
Measures before start-up:
 If a shut−off device is installed in the pressure
line: make sure that the pump−motor unit is
NOT operated with the shut−off device being
closed.
 Observe the values specified on the rating
plate before starting up the pump−motor unit.
Specifications on the rated motor current
apply at a gas entry and ambient temperature
of +40° C [104 °F].
 WARNING
Danger due to rotating parts!
Danger due to vacuum and gauge pressure!
Danger due to escaping media!
Test runs may only be conducted with the
pump−motor unit completely mounted.
 DANGER!
Electrical danger!
The electrical connection may be carried out by
trained and authorized electricians only!
