Shutdown:
Has the pump been exposed to condensate?
☞ Allow the pump to continue to run at atmospheric pressure with gas ballast valve
open for a few minutes.
Short-term:
➨ A restart is only possible after two minutes (cool-down period of start-up control
(PTC thermistor)).
Long-term:
➨ Separate pump from the apparatus.
➨ Flush pump with dry nitrogen.
➨ Change oil.
➨ Fill the pump completely with new oil (more than mark Max.!).
➨ Close manual gas ballast valve.
➨ Close inlet and outlet port (e. g. with transport caps or blind flanges).
➨ Store the pump in dry conditions.
➨ If necessary carry out oil change and maintenance prior to use if the pump is stored
longer than one year.
