ELECTRICAL APPLIANCES
Operate the appliance in accordance with the following proce-
dure:
• Remove any pans from the cooking zones.
• Ensure the cooking zones are switched off.
• Power-up the appliance by means of the main switch on the
appliance: the green indicator lights flash once (after which
they must not switch on or flash)
• Switch on and increase the cooking level of the zones: the
green indicator light for zones must flash steadily, indicating
the absence of pans.
• Place a pan of water on each cooking zone: the green indica-
tor light remains steadily illuminated.
• Select the maximum power setting: after a few minutes the
fan switches on.
• Check the current values of each phase.
