6.2 To open the ventilation unit
Before beginning any service work, isolate the power
supply voltage by removing electric plug. Wait a few
minutes before you open the inspection door of the
ventilation unit so that the fans have time to stop and
possible air heaters to cool down.
The inspection door can be opened by turning the lock
bolts with a slotted screw driver. Support the top edge of
the door with one hand when you open the lock bolts.
6.3 Filters
The filters should be replaced at least every six months.
The filters may need to be replaced more often in homes
where there is considerable dust or if there are many impu-
rities in the outdoor air.
In a new home, there is still moisture from the construc-
tion period, and the filters can become soiled more quickly
than usual. The first filter change should therefore be
made more often.
The ventilation unit must not be operated without
filters. Use only filters recommended by Swegon.
This is important, as filters with exactly the same ap-
pearance and size can have very different pressure losses
and filter capacity. If an incorrect filter is used, the venti-
lation unit may not work as designed and Swegon can’t
be responsible for possible mailfunction. Check correct
filters from the list of components.
6. Service
6.4 Heat exchanger
Check the condition of the heat exchanger whenever
servicing the unit.
Carefully rotate the heat exchanger rotor one revolution
to inspect the condition of the drive belt. Do not dam-
age the heat exchanger fins.
Check the condition of the brushes along the rotor
periphery.
6.5 Fans
The ventilation unit’s fans must be checked at least
every two years.
If necessary, clean the fan with a soft brush. Be careful
not to dislocate the fans balancing weights. If significant
amounts of dirt collect on the fan cleaning should be
left to a professional.
The ventilation unit’s fans must be removed, while
the ventilation ducts are cleaned.
6.6 Other servicing
Clean the inner surfaces of the ventilation unit by
vacuum cleaning or with a damp cloth, if needed.
Check that dirt has not collected on the surfaces of the
air heater, clean if necessary.
Check that the ventilation unit works normally and that
no alarms are shown on the screen.
