User Guide

● 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 thermoregulator 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 pres-
sure reducer that will be
located on the water
inlet after the meter.

ELECTRICAL CONNECTION
4
Our heaters are in conformity with standards in
force and consequently have all necessary safety
features. The electrical connection shall comply
with installation standard (France) NF C 15-100
and recommendations 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 f
or this water heater
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 installa-
tion.
● Connect the ends of the thermostat cables to
the screw terminals provided for this purpose
(there is no need to disassemble the thermo-
stat).
● Connect the y
ellow/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.
