Safety
Before accessing the internal components of the appliance and effecting repairs or
maintenance, ensure that the plug is disconnected from the power socket and that parts
subject to heating are allowed to cool down.
If electrical measurements should be necessary, it is preferable to measure the resistance; if
possible, avoid measuring voltages or currents.
IMPORTANT: This appliance is built partly in metal. It is therefore advisable to take great care
during repairs or maintenance to avoid scratches, abrasions or cuts.
Purpose of this manual
This Manual is intended for use by service engineers who already have experience in repairing
household water and cold appliances.
The purpose of this Manual is to provide general information about this new product and thus to
facilitate repairs.
For more detailed information regarding specific aspects, refer to the specific technical
documents for the appliance:
