2.9 Maintenance by the installer
The following maintenance must be carry out by the in-
staller:
■
Inspecting and (if necessary) cleaning the heat ex-
changer;
■
Inspecting and (if necessary) cleaning the fans.
A concise explanation of these maintenance activities is
given in the paragraphs below.
Check the condensation drain once every 2
years.
Failure to carry out (periodic) maintenance on
the ComfoAir ultimately compromises the per-
formance of the ventilation system.
2.9.1 Inspecting and cleaning the heat exchanger
Check the heat exchanger once every 2 years
1. Disconnect the power from the ComfoAir.
2. Remove the filter caps from the ComfoAir.
3. Release the front panel by unscrewing the screws
(C).
The front swings forward on ceiling-moun-
ted units.
4. Lift front panel from its hinges.
5. Disconnect condensation drain.
Take care not to trap your fingers when
mounting front panel.
6. Remove the leakage tray by removing the screws
(D and E).
The heat exchanger and leakage tray may con-
tain water!
7. Rotate locking nuts (G) on heat exchanger
a quarter of a turn.
The heat exchanger may fall downwards on
ceiling-mounted units, so ensure the heat ex-
changer is supported when rotating the locking
nuts.
