8.3 Karbantartás
VIGYÁZAT!
A telepítés, javítás, karbantartás vagy elektromos munka megkezdése előtt bizonyosodjon meg arról, hogy a készüléket
leválasztotta a hálózati áramkörről.
• Tartsa a berendezés felületét pormentesen.
• Amikor az LCD kijelzőn megjelenik a SzŰRŐ jel, porszívó segítségével tisztítsa meg a szűrőket a lenti utasítások alapján (8.b-c-d-e. ábra).
A karbantartás a belső és külső környezeti feltételektől függően változhat.
• A Szűrő figyelmeztetés visszaállításához, nyomja meg a FILTER (Szűrő) gombot (7.b. ábra

8.2 Description of Components
Fans
The fans have external rotor motors of EC type which can be steplessly controlled individually between 10–100%. The motor bearings are life time lubricated
and maintenance free. It is possible to easily disconnect and replace the fans if necessary.
Filters
The filters are of filter quality G4 for both the supply air and extract air filter. The filters need to be cleaned regularly (and replaced when polluted) during main-
tenance. New sets of filters can be acquired from your installer or wholesaler.
Heat exchanger
The unit is equipped with a highly efficient, counter-flow plate heat exchanger. Supply air temperature is therefore normally maintained without adding additio-
nal heat. The heat exchanger is removable for cleaning and maintenance during service.
Condensation drainage
Depending on the relative humidity in the extract air, condensation may occur on the cold surfaces of the heat exchanger, on one side in winter time, on the
other side in summer time (table 6.b).
The condensate water is led out through drainage pipe.
Thermistors
Temperature probes to implement temperature dependent functions.
8.3 Maintenance
•
Keep the unit surface free from dust.
•
