2.3 Maintenance by the user
As a user of the ComfoAir, you must carry out the
following maintenance:
•
Cleaning or replacing the fi lters;
• 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.
2.3.1 Cleaning or replacing the fi lters
If so indicated on the digital operating device, you
must clean or replace the fi lters.
You will see the message “FiL” and ”tEr” appearing
alternately on the display.
To replace ...
If the fi lters need replacing, follow this procedure:
• Press “OK” on the display until the fi lter alert
disappears.
• Disconnect the power from the ComfoAir.
• Remove the handles (A) from the ComfoAir
A
A
• Remove the old fi lters (B) from the ComfoAir
B
• Slide the new fi lter back into the ComfoAir.
• Refi t the handles (A) to the ComfoAir.
•
Reconnect te power to the ComfoAir.
To clean...
Vacuum the fi lters (B) with a vacuum cleaner instead
of replacing them with new fi lters.
When using the ComfoAir for the fi rst time,
it is recommended to clean the fi lters (and
valves) fi rst, as during the construction
phase the ventilation system could have be-
come dirty with building dust.
Replace the fi lters (at least) once a year.
2.3.2 Cleaning the valves (in your dwelling)
The ventilation system may be fi tted with the fol-
lowing valves:
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:
•
Remove
the valve from the wall or ceiling;
•
Clean
the valve in a solution of soap and warm
water;
•
Rinse
the valve thoroughly and wipe
dry
;
•
Place
the valve back WITH EXACTLY THE
SAME SETTING (and IN THE SAME HOLE);
•
Repeat
this procedure for the other valves.
About the valve settings...
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.
The ventilation air is supplied and discharged by
means of valves. Gaps under doors in the dwelling
ensure that the air fl ows 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.
