ELECTRICAL CONNECTION

Before installing the unit, we recommend that you check the electrical system very carefully to ensure that it
complies with the relevant regulations. The manufacturer accepts no responsibility for any damage caused by
the lack of a grounding to earth or a problem related to the power supply.
Ensure that the voltage used is 230 V / 50 Hz.
Check that the main power supply is rated for the heater's maximum power consumption (Refer to the technical
characteristics plate) and that the electrical cables and wiring are suitably rated and regulated.
Ensure that the electrical installation is fitted with the mandatory differential switch in compliance with regula-
tions.
SET UP
Fill the water heater, opening the cold-water cut-off valve and the hot water taps. When water comes out of
the taps, turn them off, starting with the lowest one (bidet) and ending with the top one (shower). In this way
any air in the heater and pipes can be bled off.
The heater must be filled with water before its first use (or after any maintenance or cleaning) and after
it has been connected to the power supply. DO NOT SWITCH ON THE POWER unless it is full, as this
could damage the resistance.
