4.
On the front of the device, loosen the four Phillips
screws (Fig. 10/1) and lower the air distribution
connector (Fig. 10/2) to the ground. Then tighten
the screws again.
5.
Protect the ventilation unit with the optional outer
casing or with an outer casing provided by others.
Screw-fix the two fixing brackets (Fig. 9/6) to the
outer casing.
The outer casing must prevent unauthorised indi-
viduals from reaching into the unit and from being
injured (e.g. by electric shock). Make sure that the
air can circulate around the unit even with the
outer casing.
The interior of the ventilation unit must remain
accessible for maintenance.
NOTICE!
Contamination
If there is a lengthy gap between installation
and commissioning of the unit, we recommend
the following measures in order to avoid cum-
bersome cleaning procedures at the time of
commissioning.
–
Cover all openings of the unit, e.g. with
plastic, to prevent the ingress of dust.
–
Remove the filters and store them in a dry
place, protected from dust; cover the filter
openings.
–
Switch off the power supply to the unit.
