Induction cooktop

Setting Cooktop Controls
Power Sharing
To get the highest power output from your cooking zones, cook
with only one cookware per heating section. If you need to use
most of your cooking zones at once, start your cooking process
on only one cooking zone within the heating
section and then
add your second cookware on the second cooking zone when
the first one has already
reached
its cooking
temperature.
Remember
to select the power setting
last for the cooking
zone you want to maintain
at full power or set the altered
power to where you want it.

Operational Noises
The electronics
generating
the induction fields are pretty
much noiseless but they do produce
heat at high power
level. A soft-sounding
cooling
fan activates
when the unit is
running multiple
cooking
zones at once or when a cooking
zone is set at very high power settings.
The buzzing
sound you could hear from your cooktop
is not
coming
from the electronics
but from the cookware
you are
using. Here are some causes of this noise:
° Most induction-ready
cookware
are made of several
layers of materials.
An encapsulated
steel layer is usually
used to harness the induction field and transform
it into
heah which is then transferred
to the other materials
by
radiant
energy. The induction field will cause the steel
layer to vibrate
against
the other materials
in which it
is encapsulated.
This is the most common
cause of noise
from the induction process. This buzzing
only happens
at the higher
power level settings. Note that high quality
cookware
manufacturers
weld this steel layer in place
which lowers or cancel this noise.
° Light weight cookware
may also vibrate.
We recommend
using heavy weight
quality
cookware.
° Cookware
with warped
bottoms
can vibrate
on the
ceramic
glass surface at high power settings.
° _
The power output of your induction cooktop
is capable
of warping
an empty pan. Never use the
higher power settings on an empty pan. Even the highest
quality
cookware
is vulnerable
to warping.
° Riveted handles on cookware
can also cause buzzing
sounds from the vibrations.
° Solid cast iron and enamelware
cookware
should not emit
any noise. Top quality
cookware
made of several layers
should also be relatively
quiet.
General Care & Cleaning
Cleaning Various Parts of Your Cooktop
Before cleaning
any part of the cooktop,
be sure all controls are turned OFF and the cooktop
is COOL.
REMOVE SPILL OVERS
AND HEAVY SOILING
AS SOON
AS POSSIBLE. REGULAR CLEANINGS
NOW
WILL REDUCE THE DIFFICULTY AND EXTENT
OF A MAJOR
CLEANING
LATER.

built-up grease, apply a liquid detergent directly onto the soil. Leave on soil for 30 to
60 minutes. Rinse with a damp cloth and dry. DO NOT use abrasive cleaners on any of
these materials; they can scratch or dull the finish.
Clean with hof_ soapy water and a dishcloth. Rinse with clean water and cloth. Do
not use cleaners wlfh high concentrations of chlorides or chlorines.
Do not use harsh
scrubbing cleaners. Only use kitchen cleaners that are especially made for cleaning
stainless steel. Always be sure to rinse the cleaners off: from the surface as bluish stains
may occur during heating that cannot be removed.
