3. MAINTENANCE, CLEANING AND DISPOSAL

ALL MAINTENANCE AND REPLACEMENT OPERATIONS MUST BE CARRIED OUT BY QUALIFIED
PERSONNEL.
Empty the unit before carrying out any maintenance operation.

3.2 General instructions

To clean the external parts of the hot water tank, just use a cloth moistened with water, with the addition of liquid
soap if necessary.
Do not use detergent powders and solvents (abrasives of any type, petrol and similar products).
Check the protection anode at least once a year (see next section).
If installed in places with risk of frost, the unit must be kept operating or completely emptied.

3.3 Emptying the unit

• To carry out emptying, turn off the faucet for filling from the mains supply, connect a hose to the drain connection (not
supplied - ref. 12 in fig. 10 and fig. 11), foreseen during the installation phase, and place the other end in an area
provided with an external drain.
• Open a draw-off point and let the water run, then open the drain connection and complete the emptying.

3.4 Inspection and cleaning inside the tank

To inspect and clean the inside of the tank, the unit must be emptied.
Remove the flanges ("F" - fig. 5 and fig. 6).
Cleaning can be done with a jet of water. Be careful not to damage the enamel of the tank and the exchanger (coil).
Refit the flanges on the inspection openings with respective seals, checking their condition (use a new seal if
necessary).
Refill the unit according to the startup instructions and check its tightness.

3.5 Anode check

The unit is protected against corrosion by a vitreous
enamel coating of the inner surface and the exchange coil.
The hot water tank also has anti-corrosion magnesium
anodes, for protection against the effect of eddy currents
(see figure opposite) which could damage it. The life of the
anodes depends on operation and the quality of the water.
The anodes can be checked and replaced (it is advisable
to check at least once a year).
