Children should be supervised to ensure that they do not play with the unit.

For installations without a thermostat or room temperature limiting device, it is prohibited to
use the fancoil in small rooms occupied by people unable to leave the room by themselves,
unless they are not under constant surveillance.
2
Since your fan coil is equipped with a water-fed heat exchanger, be sure that ambient tem-
perature does not fall below 0 °C, which could cause the formation of ice in the exchanger
pipes with consequent risks of frost damage.
3
If ambient temperature may fall below 0 °C, it is recommended to drain the coil when the
unit is not being used. To perform this operation, open the water drain valve located next
to the water connections (Fig. 21 and Fig. 22 on Paragraph 6.5).
4
During operation (as well as during installation), make sure that the air intake and
the air outlets are not blocked in any way.

7.2 ORDINARY START-UP AND MAINTENANCE
6
After connecting the unit to the pipe system and after filling the coil, bleed any residual air
in the system by following the indications of Paragraph 6.5.
Before starting the system, check the proper opening of the valves and the absence of water
7
leaks from the pipes. Verify that the condensing water is duly evacuated and the correct
running of the regulation and control devices.
8
The user has to make sure that the cassette fan coil operates by respecting
the use limits and each operation for installation and/or maintenance must
be executed by qualified personnel only.
9
Before servicing the filter or the electrical system and, in any case, before
removing the protection structures, make sure that the unit has been dis-
10
connected from the power mains.

7.2.1 CLEANING THE AIR FILTER AND THE PLASTIC PARTS
The cleaning of the filter is a very important activity of ordinary maintenance; if it is clogged, the
cassette fan coil will have a bad filtration of the air, lower capacity and higher noise levels.
The cleaning operation of the filter must be done at regular intervals, depending on the real func-
tioning of the unit and on the amount of dust in the area where the unit is installed. It is advised
to do it at least once a month, anyway.
Clean with a normal vacuum cleaner, but 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 and let it dry
to the air.
If the air filter is damaged, replace it immediately.
