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
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.
