Such humidity may, for example, form if the
humidity in the extracted air is condensed in
the filter.
5.1 Before initial start-up
The unit is NOT to be operated under any cir-
cumstances without directing the exhaust air
away from the unit.
It is important that no dust, objects or debris are al-

• The PS cable is connected, but no valves at works-
ites are open.
• Make sure that the ground check measurement has
been performed. See the Installation and Service
Manual.
5.2 Initial start-up
WARNING! Risk of electric shock
• Unauthorized personnel may NOT remain in
