The connecting tubes must be sealed while installing the water heater (flax fibre, etc.), even if crosslinked
G
PE pipes are used.
A safety unit (not supplied with the water heater) in conformity with standard EN 1487 shall be screwed
G
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
G
water heater outlet. It will be set according to the performance of the used material.
EXAMPLE OF A VERTICAL WALL-MOUNTED WATER HEATER
This safety unit includes:
1 stop valve
1 manual drain valve
1 non-return valve (to prevent
water in the water heater from
flowing back into the cold
water network)
1 safety valve set to 7 bars
1 non-return valve inspection
plug
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.).
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.
Unscrew the locking screw and remove the
G
protective cover, which contains the electrical
connection diagram.
The original connection for this water heater
G
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 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.
the screw terminals provided for this purpose
(there is no need to disassemble the thermo-
stat).
Connect the yellow/green earthing wire to
G
the terminal marked with the earthing symbol
on the door of the water heater.
Put the cover back after checking that the
G
connection terminals are correctly tightened.
If the temperature needs to be adjusted, refer
G
to the instructions inside the cover.
Put back and tighten the locking screw.

IMPORTANT
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.
