4. Maintenance and cleaning
Empty the unit before carrying out any maintenance operation.
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.
INSPECTION AND CLEANING INSIDE THE TANK
To clean the inside of the tank, empty the unit, and remove the cover (“
D
” - “fig. 1”) by undoing the screws.
Remove the flange (“
F
” - “fig. 1”). During cleaning be careful not to damage the tank and exchanger (coil) enamel.
Cleaning can be done with a jet of water and, if necessary, with the aid of a suitable tool in plastic and wood to eliminate
stubborn sedimentation.
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.
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 an anticorrosion magnesium anode to protect against the effect of eddy currents which could
damage it: the duration depends on operation and the quality of the water.
The anode can be inspected (it is advisable to do this at least once a year) and is replaceable.
To check and/or replace it, firstly empty the hot water tank as described above, then remove the black plastic cover on the
upper end-plate of the hot water tank.
To remove the anode, it is necessary to unscrew the flange “
F
” - “fig. 1” (tightening torque 25-30 Nxm). After inspection and/
or replacement, the tightness of the hot water tank must be checked.
Replacement must be done with original parts.
