The position of the droplet eliminator and demister
cassettes may have changed due to vibrations
during transport.
If there are gaps between the cassettes, mist from
the humidifier module could get into the unit and
accumulate to water.
The droplet eliminator cassettes can only be
checked upstream of the humidifier, and the demister
cassettes downstream of the humidifier. It may be
necessary to disconnect ducts to get access to the
cassettes.

part of this test, all contacts have to be checked for cor-
rect seating. This applies in particular to motor terminal
blocks, fuses, local isolators etc.
