It is necessary to connect the drain, which must always be left exposed to the atmosphere, with a drain-
age pipe that is installed sloping downwards in a place with no ice. If the network pressure is closed
to the calibrated valve pressure, it will be necessary to apply a pressure reducer far away from the
appliance. To avoid any possible damage to the mixer units (taps or shower) it is necessary to drain any
impurities from the pipes.
"GRAVITY DRAIN" CONNECTION
Specific taps must be used for this type of installation and the connection must be implemented as
shown in the diagram in (Fig.2) . With this solution, the water heater can work at any mains pressure and
no type of tap must be connected on the outlet pipe, which acts as a vent.
ELECTRICAL CONNECTION
It is mandatory, before installing the appliance, to perform an accurate control of the electrical sys-
tem by verifying compliance with current safety standards, which is adequate for the maximum pow-
er 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 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 (type H05VV-F 3x1,5 mm
The power cable (H05VV-F 3x1.5 mm
ance (Fig.3, Rif. F) and connected to the thermostat terminals (Fig.6, Rif.M).
The appliance must be grounded with a cable (yellow/green and longer than the phase cable) connect-
ed to the terminals Marked
Finally, lock the power supply cable with the special cable clamp.
Use a two-pole switch conforming with national laws in force (contact gap of at least 3 mm, preferably
equipped with fuses) to disconnect the appliance's power supply.
Before starting up the appliance, check that the power rating matches that given on the nameplate. If
the appliance is not supplied with a power supply cable, choose one of the following installation modes:
- Connection to mains with a rigid pipe (if the appliance has no cable clamp); use a cable with a minimum
3x1,5 mm

section;
- With a flexible cable (type H05VV-F 3x1,5 mm
cable clamp.
Testing and start-up of the appliance
Before powering up the appliance, fill the heater with mains water. To do so, open the mains cock and the hot
water tap until all the air has been vented from the boiler. Check for water leaks from the flanges, tighten down
the bolts not too much, if necessary. Power the appliance by actuating the switch.
