and control devices.
The user has to be sure that the fan coil operates by respecting the operational
limits and each operation for installation and/or maintenance must be executed
by qualified personnel only.
Before servicing the filter or the electrical system and, in any case, before
removing the housing, make sure that the unit has been disconnected from the
power mains. The housing must be remounted before the unit is reconnected
to the power mains.
7.2.1 CLEANING THE AIR FILTER
Cleaning the filter is a very important activity of ordinary maintenance of a fan coil; if it is clogged,
the fan coil will have lower capacity and higher sound levels.
Cleaning the filter must be done at regular intervals, depending on real functioning and on the
amount of dust in the area where the unit is installed; in any way, it is advised to do it at least once
a month: clean with a normal vacuum cleaner and if dust stubbornly adheres to the filter due to
humidity or to greasy deposits, wash the filter with a solution of neutral detergent and water.
If the air filter is damaged, replace it.
Removing filter
The filter can be easily reached in all models:
