Safety instructions
 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!
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 the
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 media 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 pump−motor unit through
open connections!
Do not insert objects into the pump−motor 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 surface of the
pump−motor unit and from hot media!
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!
1.3 Residual risks
 WARNING
Danger zone:
Hot surface of up to approx.160 °C [320 °F].
Hazard:
Possible burns.
Protective measures:
Cover the pump−motor unit with a suitable
touch protection (e.g. perforated plate cover or
wire cover).
 WARNING
Danger zone:
Fan guard
Hazard:
Long, loose hair can be drawn into motor fan
through the fan guard grate, even with
fan guard mounted!
Protective measures:
Wear hair net!
