2.4 Maintenance by the user
The following maintenance must be carry out by the
user:
• Cleaning or replacing the filters;
• Cleaning the valves (in the dwelling).
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.
2.4.1 Cleaning or replacing the filters
If so indicated on the digital operating device, you
must clean or replace the filters.
Replace the filters (at least) every six
months and clean the filters every 2 or 3
months.
You will see the message “FiL” and ”tEr” appearing
alternately on the display.
To replace ...
1. Press “OK” on the display for at least 4 sec-
onds until the filter warning disappears.
2. Disconnect the power from the ComfoAir.
3. Remove the handles (A) from the ComfoAir

5. Slide the new filters back into the ComfoAir.
6. Refit the handles (A) to the ComfoAir.
7. Reconnect the power to the ComfoAir.
Take care not to damage the filter material
with the outer ends of the filter holders.
To clean...
Vacuum the filters (B) with a vacuum cleaner in-
stead of replacing them with new filters.
When using the ComfoAir for the first time,
it is recommended to clean the filters (and
valves) first. During the construction phase
the ventilation system could have become
dirty with building dust.
2.4.2 Cleaning the valves (in your dwelling)
The ventilation system may be fitted with the fol-
lowing valves:
Exhaust valve (STB)
Exhaust valve (STC)
Exhaust valve (STV)
Exhaust valve (STK)
Supply valve (STH)
Exhaust valve (STB)
Exhaust valve (STC)
Exhaust valve (STV)
Exhaust valve (STK)
Supply valve (STH)
Exhaust valve (STB)
Exhaust valve (STC)
Exhaust valve (STV)
Exhaust valve (STK)
Supply valve (STH)
You must clean the valves (at least) twice a year:
1. Mark the setting of the valve;
2. Remove the valve from the wall or ceiling;
3. Clean the valve in a solution of soap and warm water;
4. Rinse the valve thoroughly and wipe dry;
5. Place the valve back WITH EXACTLY THE
SAME SETTING (and IN THE SAME HOLE);
6. Repeat this procedure for the other valves.
About the valve settings...
The ventilation air is supplied and discharged by
means of valves. Gaps near doors in the dwelling
ensure that the air flows in the right direction. In or-
der to ensure that the correct ventilation volumes
are maintained in the rooms, the following must be
observed:
•
do not
seal the gaps;
•
do not
change the settings of the valves;
•
do not
replace the valves with one another.
The installer will have set all the valves to ensure
the optimum performance of the ventilation system.
Therefore, do not change the setting of the valves.
After cleaning, make sure that all valves are
placed back with the same setting (and in
exactly the same ventilation hole in the wall
or ceiling) AT ALL TIMES. Otherwise, system
performance will be compromised.
