9.8 AIR FILTERS
It is really important that the coil for the air treatment can offer
the maximum thermal exchange: so the unit must always
operate with installed, clean filters.
The cleaning and the replacement of the filters are very
important operations from a hygiene-health point of view.
Operating with a clogged filter causes the reduction of the air
rate and, as a consequence, malfunctions, blocks and
possible failure of the unit.
The frequency of the filter check depends on the quality of the
external air, the operation hours of the unit, the dust and
number of people in the rooms.
In general, the ideal frequency can vary from EVERY WEEK to
EVERY MONTH. It is recommended to start with frequent
controls and reduce them according to the level of dirt.
