FIGHTER 410P
For Home Owners
The building’s ventilation devices should be cleaned
regularly with a small brush to keep the correct venti-
lation.
The device settings must not be changed.
NOTE! If you take down more than one ventilation
device for cleaning, do not mix them up.
Also check the outdoor air’s intake grille (on the house
facade). Clean if necessary.
Cleaning the ventilation devices
The heat pump's air filter (63) needs to be cleaned
regularly (approximately 4 times per year). The interval
between cleaning operations varies and depends on
the amount of dust in the exhaust air.
■ Set the switch to “0”.
■ Open the upper front cover by pulling it out by the
lower edge, then lifting it up.
■ Release the filter holder by turning the black knobs
a quarter of a turn anticlockwise.
■ Pull out the holder, take out the filter and shake off
any dirt.
Check that the filter is not damaged. New original
filters can be ordered from NIBE.
■ Assembly takes place in the reverse order.
Every third month a reminder for cleaning the filter is
shown in the display as “A-01”. Note that the time will
be set to zero by setting the switch to "0".
Cleaning the air filter
When the exhaust air filter (63) has been severely
clogged or broken the evaporator may also need to be
cleaned. However, this should only be done in excep-
tional cases. Remove the plastic hose for waste con-
densation water from its mounting before cleaning. The
hose is straightened and the condensation water will
run out. The evaporator is cleaned with water; a mild
soap solution can be applied with a sponge, if neces-
sary. The hose is then reattached in its original posi-
tion, so that a water seal is formed.
The installation is checked with regard to abnormal
noise or leakage.
