4.4 Stopping
It is recommended to run the unit isolated for typically 15 minutes pumping clean dry air at around 50-
100 mbar(a) prior to switching off. If the air stream was heavily contaminated with water vapour, a
longer period of running the unit off-line can only extend lifetime.
4.5 Taking out of operation
CAUTION
The operator must apply all relevant safety precautions. See section Safety precautions during
operation.
Also consult section Problem solving.
Procedure:
Switch off the voltage and disconnect the pump from the mains.
