• 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. 45; a CVC
3000 or VNC 2 VARIO controller is required for operation)
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.
In case of overload, the motor is shut down by a self-hold
thermal cutout in the winding.
Note: Only manual reset is possible. Switch off the pump
and disconnect from the power source. Identify and elimi-
nate the cause of failure. Allow the pump to cool down
sufficiently before restart.
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 “Notes on return to the
factory”, pg. 91) are followed.
Take advantage of our service seminars, which put special
focus on the maintenance and repair of vacuum pumps.
