2.9 Maintenance by the installer
The following maintenance must be carry out by the
installer:
• Inspecting and (if necessary) cleaning the heat
exchanger;
• Inspecting and (if necessary) cleaning the fans;
• Inspecting and (if necessary) cleaning the pre
-
heater element filter (If a preheater element is
fitted).
A concise explanation of these maintenance activi-
ties 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 performance 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 (A) from the ComfoAir.
2.
Remove the handles (B) from the ComfoAir;
3. Remove the filters from the ComfoAir.
4. Release the front panel by unscrewing the
screws (C).
5.
Slide
the front panel upwards and remove the
front panel from the ComfoAir.

6. Release the cover panel by unscrewing the
screws (D).
7. Remove the cover panel.

When reassembling the front cover, the
lower section must first be inserted behind
the raised edge to ensure a good seal.

8. Pull the strap (E) to remove the heat exchanger
and the leakage tray (F).
9. Remove the heat exchanger from the leakage
tray (F).
Install the leakage tray correctly underneath
the heat exchanger. The slanting side of the
leakage tray must be on the side of the con
-
densation drain.
During assembly of the heat exchanger,
check the position of the four rubber seals.
10. Inspecting and if necessary clean the heat ex-
changer.
- Use a soft brush to clean the lamellae.
- Use a vacuum cleaner or air gun (no high
pressure) to remove dirt and dust.
Always clean against the direction of the air-
flow. This prevent dirt from getting stuck in
the heat exchanger.
Only standard exchanger with a green cover and En-
thalpy exchanger with a blue cover:
a. Submerge the heat exchanger several times in
hot water (max. 40 °C).
b. Rinse the heat exchanger with clean hot tap wa-
ter (max. 40 °C).
c. Clasp the heat exchanger between both hands
(on the coloured side surfaces) and shake the wa-
ter from the heat exchanger.
Only an enthalpy exchanger with a bleu cov -
er can be washed with water. When having
an Enthalpy exchanger with a white cover do
never wash it with water.
Do not use aggressive cleaning agents or
solvents.
If the fans or preheater element filter also
need maintenance do not re-install the heat
exchanger yet.
11. If no more maintenance is necessary install all
parts in reverse order, reconnect the power
