Use a soft brush to clean the fan impellers.
Use a vacuum cleaner to remove dust.
Do not damage the fan impellers.
Do not damage the temperature sensor.
• Install all parts in reverse order.
• Carry out the self-test in accordance with
menu P76.
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.
Check the condensation drain once every
two years.
Fasten the screws to a maximum of 1.5 Nm.
This is roughly equal to speed 2 of an aver-
age battery-powered drill.
3.9.2 Cleaning the fi lter if a pre-heater is fi tted
The fi lter of the pre-heater (if fi tted) must be cleaned
once every 4 years:
•
Disconnect the power from the ComfoAir.
• Remove fi lters (B) from the ComfoAir.
• Release the front panel by unscrewing the
screws (C).
• Slide the front panel upwards and remove it
from the ComfoAir.
• Release the cover panel by unscrewing the
screws (D).
• 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).
• Remove the cable (P) from the PCB panel.
• Remove the pre-heater holder by sliding it up
halfway and then pulling it away from the valve.
• Remove the pre-heater fi lter located behind the
pre-heater holder.
• Clean the fi lter with a brush.
• Remove any deposit using a damp cloth.
• Install all parts in reverse order.
• Carry out the self-test in accordance with
menu P76.
The hollow side of the pre-heater fi lter must
face the pre-heater holder.
Fasten the screws to a maximum of 1.5 Nm.
This is roughly equal to speed 2 of an aver-
age battery-powered drill.
3.10 Malfunctions
If the ComfoAir suffers a malfunction, then in most
cases a malfunction alert will appear on the screen
of the digital operating device.
However, malfunction alerts may not appear on the
digital operating device in all cases, even though
there is a malfunction (or problem). A concise ex-
planation of both types of malfunction (or problem)
is given in the paragraphs below.
