CLEANING/FILTER CHANGE
• Always disconnect the power and make sure
that it can
not be connected.
• Open the lid by removing the two screws (screw-driver
PH2).
• Filter change should be done regularly. We recomend
at least once a year. The filters should not be cleaned
with compressed air or vacuum cleaner.
The
filters

are removed by pulling them straight
out. When changing filter also check if the fans are
dirty.
• The fans are taken out after the quick connectors
has been disconnected and the screw is loosen
(2)
.
Then just pull out the fan
(3)
straight out from the
unit.
NOTE! Observe that the fans will fall down when
the screw is loosened if the unit is roof-mounted.
Unscrew the motor plate from the fan housing (the outer
screws) and lift out the motor with the fan wheel. If
necessary the fan wheel and fan housing are wiped clean
with a damp cloth.
NOTE! Beware the balancing weights on the impel-
ler, be careful.
If needed, dried unit housing and the rotor unit clean
internally.

is taken out by disconnecting the quick
connector of the rotor motor, then screw out the three
screws
(5)
and then unplug the whole package.
NOTE! Observe that the rotor unit may fall down
