• Technical features of the fan motor:
- With each fan coil unit there is the possibility to have 6 different air volumes and
the relevant electric motor connections accordingly to the use requirements. The
standard electrical connection has a triad of speeds: MIN-MED-MAX (size 20: L-6,
L-4, L-1 and size 40: L5, L2, L1). The relevant nominal air capacities are indicated
in the Encl. 3 and they are referred to standard fan coil units, with clean filters, at
the temperature of 20 °C, at sea level and without external static pressure.
- The electric motor is provided with internal thermic protection; it is a monophasic
motor with capacitor permanently inserted.
