pump is open. If this constitutes a potential source of
danger, take appropriate safety measures, e.g., install
a solenoid operated gas ballast valve.
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
Important notes on working with
condensable vapors:
Allow the pump to attain its operating temperature before
pumping condensable vapors. Keep the vapor inlet pres-
sure below the permitted maximum (see ”Technical data”,
Open the gas ballast valve in case of pumping significant
amounts of vapor.
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. Wait approx. five minutes before
restarting the pump.
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. 53) are followed.
Take advantage of our service seminars, which put special
focus on the maintenance and repair of vacuum pumps.
