ATTENTION! if the condensate drainage alarm is activated, the
zone valve is closed and the fan turned off.

WIRING DIAGRAM
ACCESS TO THE SWITCHBOARD
!
A
TTENTION!
Before carrying out electrical connections, ensure that the electricity
supply has been cut off, checking that the on-off switch is in the
OFF position.
Only qualified electricians should carry out the electrical connections.
Check that the mains supply is single-phase 230 Vac/1/50 Hz (± 10%).
Operating the appliance with voltages outside the above limits could
cause malfunction and renders the warranty null and void.
The fan coil power supply line should be fitted with at least a switch
isolator in conformity with European standard EN60947-3. Make sure
that the electrical system is suitable for providing not only the working
current required by the appliance, but also the necessary current for
powering household and other electrical appliances already in use. Any
electrical and mechanical alterations or tampering render the warranty
null and void.
The motor and accessories power cables in channels or conduits should
remain inside the same until they are inside the appliances.
To access the switchboard, proceed as follows:
1 Open the cassette grille;
2 Remove the metal covers first removing the screws;
3 Carry out the wiring;
4 Replace the metal covers and close the unit panel.
Fig. 20: When several units are installed near to each other and only
one condensate drain hose is used, make sure that the capacity of the
hose is sufficient and that it is positioned on a slightly lower level than
the appliance.
