and disconnect from the power source. Identify and elimi-
nate the cause of failure. Allow the pump to cool down suf-
ficiently before restart. Wait approx. five minutes before
restarting the pump.
Avoid overheating (e.g., due to hot process gases).
Make sure the fan’s air supply is adequate. Do not place
the pump on soft surfaces (e.g., rubber foam) during oper-
ation. This may reduce or block the fans’ air supply. Check
fan regularly for dust/dirt. Clean fan guard grill if neces-
sary to avoid a reduction of ventilation.
A warm up period (approximately 15 min.) is required to
ensure that the rated ultimate vacuum and pumping speed
are attained.
Shutdown & storage
The pump can be switched off under vacuum.
Short-term:
Has the pump been exposed to condensate?
Allow the pump to continue to run at atmospheric pres-
sure for a few minutes.
Has the pump been exposed to media which may damage
the pump materials or form deposits?
Check and clean pump heads if necessary.
Long-term:
Take measures as described above regarding short-term
shutdown.
Separate the pump from the application.
Close inlet and outlet ports (e.g., with transport caps).
Store the pump under dry conditions.
