It is mandatory, before installing the appliance, to perform an accurate control of the electrical system by verifying
compliance with current safety standards, which is adequate for the maximum power absorbed by the water heater
(refer to the data plate) and that the section of the cables for the electrical connection is suitable and complies with local
regulations. The manufacturer is not liable for damage caused by lack of grounding or anomalous power supply. Before
starting up the appliance, check that the power rating matches that given on the nameplate.
The use of multiplugs, extensions or adaptors is strictly prohibited.
It is strictly forbidden to use the piping from the plumbing, heating and gas systems for the appliance earthing con-
nection. If the appliance is supplied with a power supply cable, should the latter need replacing, use a cable featuring
the same characteristics . The power cord must be routed into the hole in the back of the appliance and connected to
the thermostat terminals (M Fig. 4).
The appliance must be grounded with a cable (yellow/green and longer than the phase cable) connected to the termi-
nals marked
(G Fig. 4).
