activated carbon and electrostatic materials.
The filter should be cleaned periodically - once a month,
or at least once every season under ordinary conditions.
When the air is exposed to exceptional contamination
(near construction sites or in an industrial zone) the
filter should be cleaned more frequently.
Failure to clean the air filter will result in reduced
cooling / heating capacity and may cause damage to
the unit.

the compressor. For this purpose, walls that
excessively thick should not be left as in Fig. 12,
but should be chamfer outside to allow proper
air movement, as shown in Fig. 13.
