Operating and maintenance instructions for the ventilation unit
If the automatic boosted ventilation is always on,
the air humidity may be too high. Contact the
designer of your ventilation system.
NOTE
Ventilation is insufficient
If the ventilation is insufficient:
1. Check that the filters are clean and do not need to be
replaced.
•
If the filters are dirty, replace them in accordance with
the instructions provided in the section
‘Filters’ .
2. Check that no changes have occurred in the need
for ventilation after the design and installation of the
system.
•
If changes have occurred in the number or routines of
the people using the premises, the ventilation system
may require updating. Contact the designer of your
ventilation system.
Ventilation is noisy
Even though our ventilation units are relatively quiet, they
never run completely silently. If the ventilation system
has been designed and installed correctly (no devices are
located close to the bedroom and soundproof doors and
silencers are used), the disturbance caused by ventilation
can be reduced to a minimum.
If the ventilation is unusually noisy:
1. Check that the filters are clean and do not need to be
replaced.
•
If the filters are dirty, replace them in accordance with
the instructions provided in the section
‘Filters’ .
2. Check that the fans are clean and do not require
cleaning.
•
If the fans are dirty, clean them in accordance with the
instructions provided in the maintenance manual.
3. Check that the automated boosted ventilation for the
removal of humidity is not on.
•
Open the Information display (view the section ' Data
display'
) and browse to the parameter n1. If the
parameter is visible, the boosted operation is on.
Indoor air is too humid
In addition to feeling the air humidity, you may also
identify a too high a humidity level by listening to the
sound of the ventilation. If the automatic boosted
ventilation is always on, the air humidity may be too high
and the system may attempt to remedy the matter.
If the indoor air is too humid:
1. Check that the filters are clean and do not need to be
replaced.
•
If the filters are dirty, replace them in accordance with
the instructions provided in the section
‘Filters’
.
2. Check that no changes have occurred in the need
for ventilation after the design and installation of the
system.
If changes have occurred in the number of
people using the premises and/or the use the
shower/sauna, the ventilation system may require
updating. Contact the designer of your ventilation
system.
NOTE
Ventilation does not work
If the ventilation does not work:
1. Check that the unit is connected to the mains supply.
2. Check that a fuse has not tripped in the electricity
distribution board.
If all these matters are in order and the ventilation still
does not work, contact maintenance.
