3.2 WIRING DIAGRAM.
The solar collector probe (B11) must be con-
nected to clamps 45 and 46 eliminating the
resistance R15.
3.3 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
The following checks and maintenance should
be performed at least once a year.
- Check for water leaks or oxidation from/on the
fittings;
- Check that the safety and control devices have
not been tampered with and in particular, the
DHW regulation NTC probe;
- Check the integrity of the storage tank Magne-
sium anode;
- Check the state of the internal coil;
- Check for any slurry deposits on the bottom of
the storage tank.
