Before making any electrical connection, verify the compatibility between
power supply and the technical features of the fancoil and/or of the other
6
accessories to be connected to the unit. These features are illustrated in
the identification plate, located on one side of the fancoil (Fig. 1).

In the power supply system to the fan coil and its accessories, a double-pole
switch must be foreseen with a minimum distance of 3 mm between contacts
in each poles.
For a correct management and use of the fan coil and its accessories, the use of an
EURAPO microprocessor control or OMNIBUS control is suggested. The control has to be
chosen according to the requirements of the installation.
