WARNING:
Electrical shock can cause serious injury and even death. The electrical connections must be performed by qualifi ed technicians.
Realize the ground connection of the installation before proceeding with all the other electrical connections
External unit electrical connection
The electrical panel of the external unit is located at the front of the module, behind the frontal panel.
The power cable can be connected to the terminal indicated in the fi gure on the previous page, through the use of a grommet. In case the hole
present on the unit is not suffi ciently large, it is possible to adapt the size.
Make sure that the fastening of the electrical connections between the internal and external units are properly locked by a cable clamp, which
can easily be found on the market, in order to ensure that no contact occurs between the cables and the hot piping. This block must also ensure
a good tensile strength.
