3.9 Maintenance by the installer
As a fi tter of the ComfoAir, you must carry out the
following maintenance:
•
Inspecting the heat exchanger and fans;
• Cleaning the fi lter (if Pre-heater is
fi tted).
A concise explanation of these maintenance activi-
ties is given in the paragraphs below.
Failure to carry out (periodic) maintenance
on the ComfoAir ultimately compromises the
performance of the ventilation system.
3.9.1 Inspecting the heat exchanger and fans
The fans and the heat exchanger must be inspected
once every 4 years.

• Clean the heat exchanger, if required.
– Submerge the heat exchanger in hot water
(max. 40 °C).
– Rinse the heat exchanger with clean hot tap
water (max. 40 °C).
– Clasp the heat exchanger between both
hands (on the coloured side surfaces) and
shake the water from the heat exchanger.
Do not use aggressive cleaning agents or
solvents.
Do not re-install the heat exchanger yet. The fans
also need to be inspected. The steps below explain
how to remove, inspect and (if required) clean the
fans (after cleaning the heat exchanger) :
•
Remove the screw from the electronics car-
riage.
• Pull the electronics carriage carefully forwards.
• Release the connectors (J) and the earth wire
on the PCB panel and fully remove the cables
including the two grommets (K).
