6 MAINTENANCE
6.1
Routine
When using the appliance over time, it is essential to perform regular maintenance to ensure safe operation.
We therefore recommend stipulating a service contract.
Caution
Maintenance must only be performed by specialist personnel in compliance with current
regulations and our own instructions.
Before carrying out any maintenance and/or cleaning operation:
·
Disconnect the appliance from the mains power supply and/or close the gas.
·
Wait for a sufficient time for the appliance to cool down.
·
Do not wash the appliance with direct or high-pressure jets of water, since any infiltration of water into the
electrical components could jeopardise correct operation of the appliance and its safety systems.
Warning
For maintenance/replacement of components, order and use only original spare parts.
Replacing parts must exclusively be performed by authorised and/or qualified personnel. When replacing the
electrical components of the machine and the electrical panels, scrupulously follow the technical
characteristics for the replacement component indicated on the component itself. The appliance does not
require any special maintenance but during the use of the equipment it is advisable to check the following at
least once a year (possibly increasing the frequency depending on the degree of use):
·
The status of connections especially on the terminal board and the power supply cable, as well as the
status of the gas connections;
·
The operating condition of the various components (perform a functional test);
·
For appliances fitted with rotary resistances, remove the hub, grease it and replace the three o-ring seals
to avoid possible leaks.
