For AL41 faults
Check the value of the pressure on the hydrometer on the control
panel; if it is less than 0.5 bar proceed as follows:

- fill slowly by opening the filler tap (fig. 55) until the hand of the hy-
drometer is between 1 and 1.5 bar (fig. 56)
- reposition the mode selector to the desired position.
If the drop in pressure is frequent, contact the Technical Assistance
Service.
For fault AL60
The boiler is working normally, but does not provide any stability of
the domestic hot water temperature that, in any event, is supplied at
a temperature of around 50°C.
The intervention of the Technical Assistance Service is required.
K - Cleaning
The only cleaning operations that we recommend are those involving
the external boiler panels, which should be cleaned using just a cloth
dampened with soap and water.
In the case of stubborn marks, dip the cloth in a mixture of 50% water
and methylated spirits, or use specific products.
Do not use fuels and/or sponges soaked in abrasive solutions
or powder detergents.
It is forbidden to carry out any cleaning operations before dis-
connecting the boiler from the mains electricity supply; to do
this, turn the main system switch to "off".
