Check that the unit is perfectly levelled and that the condensate drain pipe is not
obstructed (rubble deposits, etc.).
Check that the water connections (to the heat-exchanger and condensate drain)
are sealed.
Check that the electrical wiring is perfectly tight.
Be sure that air has been bled from the heat-exchanger.
Reassemble the cabinet (where existing).
Power-up the fan coil unit and check its working efficiency.
7 USE
To use the fan coil unit refer to the instructions of the control panel provided as an
accessory, normally accessed by lifting the side door.
Air outlet grills can be swivelled 180° to direct the flow into the room or towards
the wall on which the unit is mounted.
The grills and the side doors are snapped onto the cabinet. Before removing them
in order to change their position, cut the power off and wear protective gloves.

authorised by the manufacturer or by qualified personnel.
For safety reasons before carrying out any maintenance or cleaning operation,
switch off the turning the speed selection switch to "Stop" and the power
supply switch to 0 (OFF).Be careful during any maintenance operation: you
could get injured by some metal parts therefore use protective gloves.
The fan coils FA do not require any particular maintenance operation: only the
periodical cleaning of the air filter should be carried out.
It is necessary to carry out a running in period of 100 hours in order to eliminate all
mechanical friction.
The starting up must be carried out at the maximum speed.
For good operation of the fan coils FA follow the instructions below:
- keep the air filter clean;
- do not pour liquids into the unit;
- do not introduce metal parts through the air outlet grill.
- keep the air inlet and outlet free at all times.
Each time the machine is turned on after being idle for a long period, ensure there
is no air in the heat exchanger.
Before using the unit for air conditions, check that:
- condensate drainage is performed correctly:
- the heat-exchanger fins are not obstructed by deposits of dirt. If necessary clean
the unit with low pressure compressed air or steam without damaging the fins.
9 CLEANING
