15 Maintaining the unit

Changing the filter mat and possibly occasional cleaning of the
housing are the only maintenance work that you have to carry out
at your system.
15.1

Changing the filter mat

A filter mat is positioned behind the front panel in front of the intake
fan. This filter mat prevents dirt particles in the ambient air from
entering the unit.
A strongly soiled filter mat can impair the cooling air supply. This
can lead to a system failure due to overheating.

IMPORTANT
Change the filter mat regularly, at the latest when
it is gray.
The frequency of filter changes is dependent upon
the installation site and the degree of soiling
associated with it. In normal office rooms, checking
every three months is generally sufficient, while a
monthly check would be recommended for rooms
with large amounts of dust (storage etc.).
