● The connecting tubes must be sealed while installing the water heater (flax fibre, etc.), even if
crosslinked PE pipes are used.
● A safety unit (not supplied with the water heater) in conformity with standard EN 1487 shall be
screwed onto the water heater cold water inlet.
● When using pipes in synthetic materials (PER, etc), it is highly recommended to fit a thermoregu-
lator at the water heater outlet. It will be set according to the performance of the used material.

The pressure in the
cold water network
is usually less than 5
bars.
If it is not, provide a
pressure reducer
that will be located
on the water inlet
after the meter.

IMPORTANT
ELECTRICAL CONNECTION
Our heaters are in conformity with stan-
dards in force and consequently have all
necessary safety features. The electrical
connection shall comply with installation
standard (France) NF C 15-100 and recom-
mendations in force in the country in which
the water heater will be installed (Certifying
Label, etc.).
■ CONNECTION PROCEDURE
● Unscrew the locking screw and remove
the protective cover, which contains the
electrical connection diagram.
●
The original connection for this water hea-
ter is configured for 230 V~ single phase.
For a 400 V~ three-phase connection you
need to replace the original single phase
plate by a 400 V~ three-phase kit (code
100000). Refer to the manual enclosed with
the kit for instructions for installation.
● Connect the ends of the thermostat
cables to the screw terminals provided for
this purpose (there is no need to disassem-
ble the thermostat).
● Connect the yellow/green earthing wire
to the terminal marked with the earthing
symbol on the door of the water heater.
●
Put the cover back after checking that the
connection terminals are correctly tightened.
●
If the temperature needs to be adjusted,
refer to the instructions inside the cover.
● Put back and tighten the locking screw.
The electronic generator for water heaters with "impressed current anode" has been designed
for a permanent power supply or of the type operating in off-peak hours, 8 h or 6 h + 2 h.
Make sure that the installation respects one of these two power supply options,
the guarantee conditions will not be applicable for shorter off-peak times.
The installation shall include :
● An omnipole circuit breaker with contacts
openings of at least 3 mm.
● A power cable with rigid conductors with
a minimum cross-section of 3 x 2.5 mm≈ in
single phase (phase, neutral, earth) or 4 x
2.5 mm≈ in three-phase (3 phases + earth).
● The colour of the earthing conductor
shall be green/yellow.
