Lincat IH21 Installation, Operating And Servicing Instructions page 7

The pan should be located concentrically over the glass target ring. If the inner ring
of the ceramic glass is visible around the pan, the pan is too small.
It is normal for induction generators to make buzzing, whistling and clicking noises,
especially on lower power settings.
If the ceramic glass surface is cracked, immediately disconnect the appliance
from the supply.
Control knob operation:
Connect to the mains supply and turn on using the switch located in the base panel.
The green neon will illuminate and the cooling fan will begin operating. (The IH42
has two supply cords, two switches and two neons).
Warning: Do not move the control knob directly between Power Boost and
Automatic Heat Up.
