Replacing or cleaning the filter

Version: 4.0 (19-12-2007)

4.1.1 Introduction

The filter must be replaced regularly. A dirty filter may cause
inadequate heating, cooling or ventilation as well as a high
noise level. The interval at which the filter is to be replaced
depends on the local situation.
New filters are available from Biddle. You may also clean the
filter material with, for instance, a vacuum cleaner. After some
cleanings, however, the filter must be replaced.
