5. Connecting the water heater to the electricity

u
Check the compatibility of the water heater with the electrical installation.
v
If the water heater is pre-wired, connect the water heater's power supply cable to a
cable outlet (the water heater should not be connected to a socket).
If the water heater is not pre-wired, the use of a rigid cable connection with a mini-
mum cross-section of 3 x 2.5 mm
in three-phase (3 phases + earth) is essential (refer to the «wiring diagram» section).
w
Check that the water heater is full by turning on a HOT water tap. COLD water should
flow out.
If the water heater is switched on when it is empty, there is a risk of damage (not
covered by the warranty).
x
Switch the electricity back on.
y
A direct connection to the resistors (without passing through the thermostat) is strictly
forbidden as it is extremely dangerous, the water temperature would not be limited.

6. Commissioning the water heater

u
If your electrical distribution board is equipped with a day/night switch (reduced night
tariff), move it to 1 (forced operation).
v
There may be some light smoke when heating starts (NORMAL operation for
Chauffeo+).
After a while, water should flow drop by drop through the safety unit (connected to
a waste water drain pipe). During heating, and depending on the water quality, the
water heater can emit a sound similar to that made by a kettle. This sound is nor-
mal and does not mean there is a fault.
w
Wait for heating to finish before using your water heater fully (see specifications
table to determine the estimated time depending on your model).
The thermostat is set in the factory to 65 °C (± 5 °C). It is possible to modify
this setting by the thermostat knob. Reducing the regulation temprature can
help reduce limescale. For 50L immersion slim water heater, indicator light is on
during heating phase only.
