CONNECTIONS FOR THE INTAKE OF FRESH EXTERNAL AIR
The unit can be connected to a fresh air intake conduit via the circular KFLD flange accessory
(diameter 100mm), applied to the vent. The application of the flange requires a hole to be opened
up on the side. The connection with the outside is direct, regardless of unit ventilation.
The KFLD accessory also includes a deflector, to be assembled inside the unit.
ELECTRICAL WIRINGS
The unit must be connected directly to an electrical outlet or to an independent circuit. The FCL
cassette fan coils must be powered with a current of 230V ~ 50 Hz and connected to the earth; the
line voltage must however fall within the tolerance of ±10% compared with the nominal value.
To protect the unit against short-circuiting, fit an omnipolar thermal trip max. 2A 250V (IG) to the
power line, with a minimum contact opening distance of 3mm.
The electrical power cable must be of the H07 V-K or N07 V-K type with 450/750V insulation if
inside a tube or raceway.
Use cables with double H5vv-F type insulation for visible cable installation. When making the
connections, follow the wiring layouts supplied with the equipment and shown in this document.
The four-speed fan speed permits various connection alternatives, connect the cables from the
control panel to the terminals of the three speeds chosen.
