Replacing or cleaning the filter

42
5.1.1 Introduction
The filter must be cleaned regularly. A dirty filter may cause
inadequate heating as well as a high noise level. The interval at
which the filter is to be cleaned depends on the local condi-
tions.
You may clean the filter with, for instance, a vacuum cleaner.
After some cleanings, however, the filter must be replaced.
New filters are available from Biddle.
5.1.2 Tracking filter service life
The control panel can track and display the service life of the
filter (see section 3.4.1).
You can set the maximum filter life (filter service life, on expiry
of which the filter is considered dirty) using function no. 3 at
the manager's level (see section 4.2.3).
You must reset the service life yourself after replacing or
cleaning the filter (function no. 2 at the manager's level, see
there).
You may also choose to disable the track & display feature
(function no. 4 at the manager's level, see there).
5.1.3 Removing the filter
