3. Servicing

3.1 Service reminder

The service reminder is activated with preset
time intervals and the "Service reminder" text
is displayed on the Premium control. As a fac-
tory setting, the service reminder is not in op-
eration. It can be put into operation under the
'Service reminder' menu point in the 'Install.
and service' menu. As a standard value, the
service reminder is given at six-month intervals.
The service reminder can be reset to zero from
the 'Install. and service' menu, 'Alarms' point.

3.2 To open the ventilation unit

Before you begin any service work, isolate the
power supply voltage to the ventilation unit
by pulling out its electric plug from the wall
socket. Wait a few minutes before you open
the inspection door of the ventilation unit so
that the fans have time to stop and possible air
heaters have time to cool down.
The lock bolts of the inspection doors are
located in the upper and lower edge of the
door under the cover plates. The cover plates
can be removed by shifting them as shown in
the image below.
Open the inspection door by turning the two
lock bolts with a screw driver for slotted screw
heads. The door can then be carefully lifted
away when the lock bolts have been opened.

3.3 Filters

The filters should be vacuum cleaned or brushed
clean at least every six months and should be
replaced at least once per year. The filters may
EN
need to be cleaned or replaced more often in
homes where there is considerable dust or if
there are many particles in the outdoor air.
The ventilation unit must not be operated
without filters. Install only filters recommended by
Swegon in the ventilation unit. Check in the list of
components that you have selected correct filters.

Important
Set the fan speeds in accordance
with national regulations when
you commission the ventilation sys-
tem. The system should be commis-
sioned by a qualified person, and
the airflows must not be changed
on one's own responsibility, since
doing so could disrupt the way the
ventilation system operates.
Swegon reserves the right to alter specifications.
