MAINTENANCE OF THE MACHINE

CHANGING THE PARTS

Before carrying out any maintenance work, disconnect the appliance from the gas and electric supply.

To replace different components such as burners, taps and electrical parts you must take out the hob from the kitchen unit by releasing the fixing hooks, unscrew the fixing screws of the burners on the work top, unscrew the fixing nuts of the electric plates which are visible on the lower part of the hob and remove the worktop in order to carry out the replacement of the defective parts.

NOTE: If the taps need replacing you also need to unscrew the two fixing screws of the gas ramp at the bottom of the hob which are found on the upper part of the latter.

For appliances equipped with automatic “ON” switches you must dismantle the “ON” switch chain before replacing the taps.

You are advised to change the seal on the tap every time you replace a tap in order to ensure a perfect hold between the body and ramp.

Type/ section of mains cable H05VV-F 3x0,75 mm2 or H05RR-F 3x0,75 mm2

WARNING: If you replace the electric mains cable the installer must have the earth conductor about 2 cm longer than the phase conductors and must also take heed of the warnings regarding electric connection.
