5.1 Introduction
This chapter comprises those maintenance activities that the
user himself can perform. Maintenance activities and repairs
that must be performed by an installer are described in chap-
ter
6 Servicing .
5.2 Replacing or cleaning the filter
The filter must be cleaned regularly. A dirty filter may be the
cause of inadequate heating and a high noise level. The inter-
val at which the filter must be cleaned depends on the sur-
roundings.
By default, filter contamination is monitored on the basis of
the amount of time that the unit is in operation. As an option,
the unit can be fitted with a filter sensor which measures filter
contamination. You can change the time between filter clean-
ing sessions by adjusting the maximum lifespan of the filter or
the cleaning interval.
You can clean the filter with a vacuum cleaner, for instance.
After several cleanings, however, the filter must be replaced.
New filters are available from Biddle.
5.2.1 Procedure when replacing the filter
1. Select menu > Filter > Cleaning the filter on the control
panel.
2. Wait until the fans have stopped and the heat exchanger
has cooled down.
3. Clean or replace the filters.
4. Select ok on the control panel when you have finished
cleaning or replacing the filters.
The lifespan of the filters is hereby reset to zero.
