ELECTRICAL CONNECTIONS
RECOMMENDATIONS
Before carrying out electrical connections, ensure that the electricity supply to the supply line 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 ducts should remain inside the same until they are inside
the appliances.
