disconnected using a suitable main switch that must 

be supplied and installed by the installer.

Respect safety distances between the unit and other 

equipment or structures.Guarantee adequate space 

for access to the unit for maintenance and/or service 

operations;

Power supply:the cross section of the electrical

cables must be adequate for the power of the unit

and the power supply voltage must correspond with

the value indicated on the respective units.All units

must be earthed in conformity with legislation in

force in the country concerned.

Hydraulic connections should be carried out as

indicated in the instructions to guarantee correct

modified or tampered with as this may create 

situations of risk.Failure to observe this condition

absolves the manufacturer of all liability for resulting

damage.

used in applications compatible with its performance

characteristics, i.e. residential or commercial applications

combined with a fan coil unit, low temperature radiators

and underfloor heating. It should never be used for
underfloor cooling, as doing so may damage the plate

heat exchanger.
