Operation and Service megaSun 7900

5.7 Filter mats

Cleaning intervals The cooling air is drawn in through two dust ﬁlters. Depending

on the installation site, clean the ﬁlter mats or, if necessary, re-

place them after approx. every 100 hours of service. To ensure

a trouble-free service of the unit, exclusively use original spare

ﬁlter mats.

Take the opportunity to check the heat exchangers of the air-

conditioning unit as well to see if they are dirty. (Section 2). Dirty

heat exchangers considerably reduce the capacity of the air-

conditioning unit. Vacuum-clean the heat exchangers if neces-

sary.

are replaced. For that purpose you will have to open the bed

(see Section 3.2).
