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 minimum cross-section of 3 x 2.5 mm
2
in single-phase (phase, neutral, earth) or 4 x 2.5 mm
2
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 ow 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).
After a while, water should ow 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 nish before using your water heater fully
(see specications table to determine the estimated time
depending on your model).
