4. Service
4.1 Service reminder
The service reminder is activated with preset
time intervals and the symbol is displayed
on the control panel’s screen. As a factory set-
ting, the service reminder is not in operation.
It can be put into operation under the main
menu item “Diagnostics”/”Service reminder”.
The recommended service interval for the
ventilation unit is six months.
When servicing has been performed, the
service reminder is reset from “Alarm” in the
main menu.
4.2 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.
On the R3 ventilation unit the lock bolts for the
inspection doors are located on 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.
On the R5 ventilation unit the lock bolts are vis-
ible on the upper and lower edge of the door.
Open the inspection door by turning the two
lock bolts with a screw driver for slotted screw
heads. The R5 ventilation unit’s door has
hinges while the door on the R3 ventilation
unit can be carefully lifted off when the lock
bolts have been opened.
4.3 Filter
The filters should be replaced at least every six
months. The filters may need to be cleaned or
replaced more often in homes where there is
considerable dust or if there are many impurities
in the outdoor air.
The ventilation unit must not be operated
without filters. Use only filters recommended by
Swegon in the ventilation unit. This is important,
as filters with exactly the same appearance and
