6. Domestic maintenance advice
Your appliance should be checked by a professional every 2 years, in order to guarantee its long-term
performance.
6.1 The safety unit
Manœuvrez régulièrement (au moins une fois par mois),
la soupape du groupe de sécurité.
Cette manipulation permet d’évacuer les éventuels
dépôts pouvant obstruer le groupe de sécurité.
Le non-entretien du groupe de sécurité peut entraîner
une détérioration du chauffe-eau (non couvert par la garantie).
6.2 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).

The water heater is empty when the water stops flowing

Draining can take up to one and a half hours or more.
z
Once completed, follow the steps in paragraph 5
“commissioning” (page 28) to return your water heater
to working order.
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).
