To enter into the terminal compartment unscrew the 2 screws on the cover.
(To access the screws, remove the decorative caps on the control access panel).
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 connec-
tion 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 multi plugs, 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 connection. If the appliance is supplied with a power supply cable, should the latter need re-
placing, 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.7-8 ).
The appliance must be grounded with a cable (yellow/green and longer than the phase cable) connect-
ed to the terminals marked
( G Fig.7-8 ).
