with a cooling module, in which case the air handling unit
will only have one exhaust air filter.

condensate drain plug from one base pate to drain
the condensate before opening the base plate.
NB! When changing filters, the unit must be switched
off (press function button for at least 2 seconds),
disconnected from the mains and prevented from
being switched on.
• Carefully open the base plate while it is supported.

check component condition and cleanliness. Clean
the components if necessary.

in the filter frames. The arrow on the side of new
filters shows flow direction. The arrow must point

(certain models only).
