Biddle recommends to have the following inspection and main-
tenance works performed by an installer each year.
All models
• Check if the filter is clean enough, and not damaged.
Replace the filter if necessary (see section 4.1).
• Check the discharge grille for contamination, and clean it if
necessary (see section 4.2.3).
• Check if the heat exchanger or the electric heating coils
are clean. Settled dust may cause unpleasant smells.
Gently remove dust with a vacuum cleaner.
c
Caution:
The fins of the heat exchanger are delicate parts. Do not
damage them.
• Check the operation of the fans.
Models with ventilation
• Check if the ventilation valve closes properly in both posi-
tions.
• Check if the valve automatically falls to shut if the power
supply is interrupted.
All models with cooling
• Check if the condensate drain tray and pipe are clean.
Contamination may lead to poor drainage and to growth of
bacteria and fungi.
