ELECTRICAL CONNECTIONS
CONNECTIONS TO THE TERMINAL BOARD
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 mal-
function 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.
The cables should be sufficiently long so that they are not permanently taut or
create throttling or pressure on metal parts (see Pic. 16). The power cables
should be sufficiently long so that in the event of accidental tugging the active
wires are subjected to stress before the earth wire. Connect the earth wire to the
relative terminal marked with the symbol .
Check the earth connection. Comply with the safety regulations in force in the
country of installation.
WITHOUT CONTROL PANEL
The electrical connections should be made to the terminal board on the side of
the appliance.
Each terminal is identified by the label to be found on the terminal board.
WITH CONTROL PANEL
The electrical connections should be made directly to the control panel, as shown
by the relative wiring diagram. If the control panel has an electronic temperature
sensor (NTC) this sensor will be powered by mains voltage (230Vac/1/50 Hz)
and is therefore provided with double insulation.
CAUTION: FAILURE TO COMPLY WITH THE INDICATED CONNECTIONS
MAY CAUSE MOTOR BURNOUT!
CONDENSATE WATER DRAINAGE
The condensate drain pipe should slope downwards by at least 3 cm/m and
should not have ascending or throttled section in order to ensure a regular flow
of water. It is advisable for a trap to be fitted. The condensate drain pipe should
be connected to a rainwater drainage system. Do not use sewage system to
avoid possible odours in the event of evaporation of the water in the trap. Upon
completion of work, check that the condensate flows out properly by pouring
water into the tray (see Pic. 14 and 15). The condensate water drainage system
should be fabricated
in a workmanlike manner and should be periodically checked. The manufacturer
cannot be held liable for any damage caused by dripping in the absence of a
solenoid valve or of periodic maintenance of the drainage system.
