3-1.Selection of installation equipment
Cut out the work surface according to the sizes shown in the drawing. For the purpose of
installation and use, a minimum of 5 cm space shall be preserved around the hole.
Be sure the thickness of the work surface is at least 30mm. Please select heat-resistant
work surface material to avoid larger deformation caused by the heat radiation from the
hotplate. As shown below:

Chapter 7 Trouble shooting
Table 1 FAQ
Problem
Possible phenomenon
what to do
1.One or two cooking
zones are not woking
a. What's the display board show?

1.b,1.c and 1.d first, if it is not the
problem of b,c or d, check the coil and
power board then replace the broken
one.
2)If display nothing, check if the power
board or EMC & power supply board or
power cable is broken, then replace the
broken one.
b. Please check what pot does the user
use, and dimension of the pot bottom? If
other zones use this pot can work or not?
1) If other zones can work with this
pot,only one or two zones can not and
display U, then the bottom of pot should
be too small.
