GENERAL
INTRODUCTION
Model VI2 is a single 2.2KW cooker.
Model VI3 is a single 3KW cooker.
Model VI22 is a double 2.2KW cooker.
Model VI33 is a double 3KW cooker.
Model VI23 is a double cooker with one 2.2KW cooker and one 3KW cooker.
The induction cooktop will not heat the way a resistance heater conducts to the pan. A magnetic induction coil is
beneath the ceramic top. This coil creates a magnetic field that requires a steel or iron pan to complete the
magnetic loop. If the pan is not present, the cooktop stays in a “cool” ready state without using much current. It is
necessary to use iron or steel pans, or special pans designed for induction use. Ceramic, glass, pottery and some
special stainless steel pans will not complete the magnetic loop and, therefore, will not heat properly, and should
not be used.
How to Distinguish a Usable Pan
Put the pan filled with water on the center of the cooktop and turn the control knob to the desired cooking level.
The indicator light will light continuously for a usable pan and will blink for an unusable pan.
Usable Pans Which Have Slower Rates of Heat Transfer
Pans with smaller bottom diameter or partially contacting bottom may be usable but will have reduced heat
transfer rates. These may be acceptable for warming but not for frying.

INDUCTION COOKERS - GENERAL
4
Recommended Pans
Pans made of cast iron, enameled iron, or stainless steel with an iron inner layer are recommended. Stainless
steel pans with 18-0, 18-8, 18-10, and 18-Cr material are acceptable if a magnet will attach itself to the pan and if
the shape of the pan is acceptable. Pans with a flat bottom 5" to 10½" in diameter are recommended. Thin pans
may deform during heating; a thicker wall and bottom are recommended. Pans made of 18-8 stainless steel and
pans with a smaller diameter bottom may have slower rates of heat transfer.

INDUCTION COOKERS - GENERAL
5
Unusable Pans
Pans made of porcelain, earthenware, heat-resistant glass, copper, or aluminum are not recommended because
they do not transfer heat from the magnetic induction field.
TOOLS
•Standard set of hand tools
•VOM with AC current tester (Any VOM with a
sensitivity of at least 20,000 ohms per volt can
be used.)
•Thermal compound Part # 819643
•Demeyere sauce pan with 26cm top opening
and 24cm bottom PMI Part # 424971-1
&
Fiberglass screwdriver Part # 424998-1

LOCATION
Position the cooktop on a suitable level countertop
surface. Do not locate the cooktop near fryers, a hot
stove, or over an oven. The electrical controls inside
the cooktop will shut down if they overheat (above
110°F). Refer to the Installation and Operation
Manual for complete installation instructions.
CONTROLS
Control Knob Turn counterclockwise to OFF; clockwise to desired cooking level.
Indicator Light:
On Indicates that power is ON and at what cooking level.
Blinking If the indicator light blinks continuously, it indicates the cooktop is in stand-by mode. This
means no pan is detected and heat is OFF. Cooktop will shut off in 3 minutes.
If cooktop is in stand-by and has shut off after 3 minutes, it must be reset. Reset cooktop by
turning control knob to OFF, then ON to desired cooking level.
If the indicator light blinks intermittently for 2 or 3 seconds and then stops, it indicates an
elevated cooking temperature of 380
(
F or higher. This is normal. The cooktop is ensuring
that maximum internal temperatures are not exceeded.

CLEANING
WARNING: DISCONNECT ELECTRICAL POWER
BEFORE CLEANING.
Clean the ceramic cooktop surface by using a cloth
moistened in warm water, or a solution of detergent
and warm water. For stubborn stains, ScotchBrite or
a soft paste of cleanser may be used; do not use
abrasive materials or harsh scouring action because
this could damage the surface.
Snap out air filters located on the bottom of the
cooktop and wash them in a sink. Dry filters before
reinstalling.
NOTE: Do not operate without filters in place. Filters
must be kept clean to prevent unit from overheating.
Keep area around unit clear to insure proper air
circulation.
