Domestic maintenance advice

Your appliance should be checked by a professional every 2 years, in order to guarantee its long-term perfor-
mance.
8.1.

The safety unit

Move the safety unit valve regularly (at least once a month).
This allows deposits which could block the safety unit to be drained away.
Failure to perform maintenance on the safety unit may result in deterioration of the water heater
(not covered by the warranty).
8.2.

Draining a water heater

If the water heater needs to remain switched off for more than a week (in a second residence for
example), and it is located in a place exposed to frost, it is essential to drain the water tank in order to
protect against corrosion.
Once the water heater is drained, bleed all the pipes in your house (turn on all your house's cold and hot
water taps so that the pipes are empty).
Switch off the power
u
Turn off your general cold water inlet valve.
v
Turn the safety valve wheel (¼ of a turn).
w
Turn on the HOT water valves in order to draw in the air.
x
The water heater is empty when the water stops flowing to the safety unit.
y
Draining can take up to one and a half hours or more.
Once completed, follow the steps in paragraph 7 "commissioning" (page 47) to return
z
your water heater to working order.
8.3.

Maintaining the tank

Check the condition of the magnesium anode every two years and replace it if its diameter is less than 10
mm (in the case of ACI versions, the anode does not require any maintenance). It is strongly recommended
to have maintenance performed on the tank by a professional every 2 - 3 years depending on the quality
of the water: draining and limescale removal. In areas where the water is hard, it is possible to treat the
water with a softener. This should be regulated and the water hardness should remain greater than 8°f.
Using a softener does not invalidate our warranty as long as it is used in accordance with professional
standards, and is checked and maintained regularly.
Do not throw your appliance away in the domestic waste, but take it to a specially designated
place (collection point) where it can be recycled.
