 WARNING
When working on the unit, there is a danger
of injury, e.g. in the form of cuts/cutting off,
crushing and burns!
During all work on and with the pump-motor unit
(transport, installation, operation, shut-down,
maintenance, disposal) wear personal safety
equipment (safety helmet, protective gloves,
safety shoes)
!
 WARNING
Hair and clothing can be pulled into the unit
or caught and wound up moving parts!
Do not wear long, loose hair or wide, loose
clothes! Use a hair net!
 DANGER
Electrical danger!
Work on electrical installations may be carried
out by trained and authorized electricians only!
 DANGER
Electrical danger!
Before beginning work on the unit or system, the
following measures must be carried out:
 Deenergize.
 Secure against being switched on again.
 Determine whether deenergized.
 Ground and short-circuit.
 Cover or block off adjacent energized parts.
 DANGER
Electrical danger!
Do not open the motor terminal box until
absence of electricity has been ensured!
 WARNING
Danger due to vacuum and gauge pressure:
sudden escape of fluids (skin and eye
injuries),
sudden drawing in of hair and clothing!
Danger due to escaping fluid: Burns!
Use mounting elements, connections, lines,
fittings and containers with sufficient freedom
from leaks and strength for the pressures which
occur.
Check the mounting elements, connections,
lines, fittings and containers for strength, leaks
and firm seating at regular intervals!
 WARNING
Danger from rotating parts (external 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 fluids (skin and eye
injuries), sudden drawing in of hair and
clothing!
Danger due to escaping fluid: Burns!
Start-up 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 vacuum pump/compressor cover,
–
the muffler 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.

Before beginning work on the pump-motor unit,
take the following measures:
 Shut down pump-motor unit and secure
against being switched on again.
 Attach a sign on the system controller and on
the control elements for the pump-motor unit:
"DANGER! Maintenance work on vacuum
pump/compressor! Do not switch on!"
 Wait for pump-motor unit to come to a
complete stop. Observe run-on time!
 Allow pump-motor unit to cool!
 Shut-off lines. Release pressure.
 Make sure that no vacuum or gauge pressure
is present in the lines/tanks to be opened.
 Make sure that no fluids can escape.
