V. MAINTENANCE AND SERVICE
IMPORTANT: Before cleaning the appliance, make sure you have turned the product
of and disconnected it from the electric power.
Do not use insecticides, solvents or aggressive detergents that could damage the
painted parts or plastic materials.
To ensure the efficiency and long life of your water heater, we recommend to
keep your appliance in perfect state, clean the resistance every two years approx.
If the appliance uses water that is characterized with high hardness, clean them
more frequently (1/year), or we recommend the use of a water softener.
The use of decalcifying liquid is recommended, but if not used, the resistance can
be cleaned by removing the crusted lime, taking special care not to damage the
resistance shell.
The magnesium anodes (Fig.1) must be replaced every two years, if not, the
warranty is invalid. With aggressive water, or water high in chlorides, checking the
state of the anode is recommended once a year. To replace it, the resistance must
be removed and unscrewed from the securing clamp.
Important: the magnesium anode is a consumable element, not replaceable
through warranty.
