Installation Manual : Electric connections and commissioning
4. Connecting the water heater to the electricity
u
Check the compatibility of the water heater with the electrical
installation.
v
The use of a rigid cable connection with a minimum
cross-section of 4 x 2.5 mm
2
in three-phase (3 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.
5. 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).
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 normal 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).
