The colder components of the sorption module are
separated from the ambient air by cover panels. The
moisture present in the ambient air cannot condense
on the cold components.
Inside the sealed section, there is a desiccant bag that
absorbs moisture from the enclosed air.
■
Replace the desiccant bag at every service, at least
once a year.
■
Operate the appliance only with the desiccant bag
and cover panels in place.
!
Please note
Any damage to sealing tape
A
means the
evaporator unit is not tightly sealed which will
lead to corrosion of the components within it.
■
Remove the sorption module cover panel only
for service purposes and do so carefully.
■
Before fitting the cover panel, check complete
length of sealing tape
A
for damage and
replace if required.
■
Fit the cover panel carefully, ensuring a per-
fect fit.
