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 activities
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.

The external filters must be

The CC Ease panel will display one of the above filter
warnings.
The internal filters are included in the stand-
ard configuration of the ComfoAir. The ex-
ternal filters (optional) is part of the ducting
of the ventilation system, and does not form
part of the ComfoAir.
To replace ...
1. Press “
” on the CC Ease panel for at least 4
seconds 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.
To clean...
Vacuum the filters (B) with a vacuum cleaner instead
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 following
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 en-
sure that the air flows in the right direction. In order to
ensure that the correct ventilation volumes are main-
tained 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.
