 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!
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.
 WARNING
Danger from rotating impeller:
Cutting/cutting off of extremities!
The rotating impeller is accessible with the inlet
and discharge connections open!
Do not reach into the unit through open
connections!
Do not insert objects into the unit through the
openings!
 WARNING
Danger from rotating impeller:
Cutting/cutting off of extremities!
The rotating impeller is accessible with the inlet
and discharge connections open!
With free entry and exit of gases, i.e. with direct
intake out of or direct feeding into the
atmosphere without piping, the following
therefore applies:
Provide the inlet and discharge connections of
the pump-motor unit either with additional
mufflers or with additional piping of a sufficient
length to prevent access to the impeller!
 WARNING
Danger of burns from hot surfaces of the
pump-motor unit and from hot fluids!
High temperatures of up to approx. +160°C
[+320°F] can occur on the surface of the pump-
motor unit.
Cover the pump-motor unit with a suitable touch
protection (e.g. perforated plate cover or wire
cover).
Do not touch during operation!
Allow to cool after shut-down!
