electrical standards and the wiring diagram corresponding to the unit model.
Any modification performed without our prior authorisation may result in the unit’s warranty being declared
null and void.
The power supply cable section must be sufficient to provide the appropriate voltage to the unit’s power
supply terminals, both at start-up and under full load operating conditions.
All fan coil units are designed for operation under 230 volts, single phase, 50 or 60 cycles .
A voltage variation of ± 10 % with regard to nominal voltage 230 V is acceptable.
Before making the connections, be sure that the available power supply has the same voltage and phase as
that shown on the fan coil unit nameplate.
Line and low voltage wiring must be done in accordance with electrical code whichever is applicable.
Earthing of unit is imperative.
