USEFUL INFORMATION
Before you clean the unit, make sure you have turned it off by setting its external switch to OFF. Do not use
insecticides, solvents or aggressive detergents: these can damage the unit's painted and plastic parts.
If the water is cold:
- Check that the appliance is connected to the power supply and that the external bipolar switch is ON;
- Check that the temperature adjustment knob is not set to the minimum;
- Check the heating elements;
- Inspect the bypass pipe (Fig. 5, Ref. X);
If water is boiling hot (steam out of the taps):
Disconnect the appliance from the power supply and contact the Technical Assistance Service.
The hot water delivery is insufficient
Disconnect the appliance from the electricity supply and have the following checked:
- the pressure of the water mains;
- the condition of the deflector on the cold water intake pipe;
- the condition of the hot water pipe;
- the electrical components
Water trickling from the pressure safety device
During the healing phase, some water may trickle from the tap. This is normal. To prevent the water trickling, a
suitable expansion vessel must be installed on the flow system. If the trickling continues even after the healing
phase, have the following checked:
- device calibration;
- the pressure of the water mains.
Caution: Never obstruct the appliance outletl
IF THE PROBLEM PERSISTS, NEVER ATTEMPT TO REPAIR THE APPLIANCE YOURSELF, BUT ALWAYS
CONTACT QUALIFIED TECHNICIAN.
