the exhaust waste vapor condenser in particular might
be elevated in case of permanent high gas flow. The
temperatures that are produced during operation may
cause burns. Avoid direct contact with the surface.
Provide a suitable contact guard if necessary.
• Ensure that the coolant outlet pipe at the waste vapor
condenser is always free and that it cannot get blocked.
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
Check the liquid level in the catchpots regularly and drain
condensate in time to prevent overfilling. Install a level
sensor (see “Accessories / Spare parts”, pg. 43) for
monitoring, if necessary.
Provide appropriate protective measures to allow for the
possibility of failure and malfunction . The protective mea-
sures must also allow for the requirements of the respec-
tive application.
A temperature sensor in the winding protects the pump
motor. In case of excess temperature or if the motor is
blocked, the motor is shut down.
If the vacuum pump is switched off due to this safety pre -
caution, the error must be cleared manually:
Unplug pump from the power supply

Eliminate cause of
error

Allow pump to cool down

Switch vacuum pump
back on.
Maintenance and repair
In order to comply with laws (occupational, health and
safety regulations, safety at work law and regulations for
environmental protection) vacuum pumps, components
and measuring instruments can only be returned when
certain procedures (see section “
Repair - Maintenance -
Return - Calibration ”, pg. 83) are followed.
