Introduction
Please read these instructions COMPLETELY
AND CAREFULLY. They will save you time and
effort and help to ensure optimum cook-top
performance. Be sure to observe all WARNINGS.
These installation instructions are intended for use
Counter space must be provided for installation of
your new cook-top. When choosing a location
consider the following IMPORTANT
CONSIDERATIONS:
• Cabinet storage space located above the
cook-top should be avoided, to eliminate the
by a qualified installer. In addition to these
instructions the cook-top shall be incralled:
• In the United States, in accordance with the
National Electric Code/State and Municipal codes
and/or local codes.
• In Canada, in accordance with Canadian Electric
Code C22.1-1atest edition/Provincial
codes and/or local codes.
COUNTER PREPARATION
and Municipal
These shall be carefully followed at all times.
TOOLS YOU WILL NEED
The following tools are needed to install your new
cook-top:
Tape measure and straightedge or ruler
Pencil
Phillips screwdriver
Pliers
Wire cutters and wire stripper
1" hole saw
Hand or saber saw
POWER REQUIREMENTS
The cook-top must be supplied with the proper
risk of burns or fire caused by reaching over
heated surface units of the cook-top. If you
choose to install cabinet storage above the
cook-top, install a range hood that extends
out horizontally at least 5" (127 mm)
beyond the bottom front edge of the
cabinets.
• If you choose to install cabinet storage above
• the cook-top, do not store any item(s) that
could be of interest to children in the
• cabinets above the cook-top. Children
•
climbing on the cook-top could be seriously
burned.
• If you choose to install cabinet storage above
the cook-top, cto not store heavy, hard
objects that if dropped could damage the
ceramic cooking surface in the cabinets
above the cook-top.
STEPS FOR INSTALLATION
The following pages provide a step by step guide
for installation of the cook-top arranged as
follows:
voltage and frequency. The cook-top must be
connected to a three wire or four wire, single phase,
240 or 208 volt, 60 Hz AC only electrical supply
on a separate circuit fused on both side of the line.
A circuit breaker or time-delay fuse sized not to
exceed the circuit rating of the appliance specified
• on the serial/rating plate located on the bottom of
the cook-top is recommended.
The cook-top must be connected with copper wires
ONLY.
It is recommended
that you have the electrical
wiring and hook-up of your cook-top performed by
a qualified electrician. After installation is complete
have the electrician show you where the main
disconnect is and which of the circuit breakers/fuses
are for the cook-top.

Attaching
Fastening
Rails
used for both NKT 72 and NKT 92 series
90*
To attach the fastening rails:
I. Mark the center as shown in drawing.
2. Align rails using notch.
3. Secure the rails tightly using screws.
Note: a. The top flange of rail must sit tightly
against the counter top.
b. If counter top is tiled, the lower
screws holes in the rails should be
used.
Important:
• Do all counter top preparation, before
installing the cook-top. Be sure to clean area
after cutting and before installing cook-top.
SPECIAL
NOTE:
Use plugs or sleeves for screws or glue rails in
place, using a temperature resistant two component
adhesive which is suitable for bonding metal to
stone, when installation is in granite or marble
counter top.
Chips, and other debris from cutting of the
counter may impair the function of electrical
components.
• Seal the cut surfaces with silicone rubber,
heat resistant enamel or casting resin, to seal
the surface against moisture.
Placing
the Cook-Top
1. Thread the cable through the cutout opening.
2. Gently place the cook-top into the cutout,
taking care to assure that cable does not
become pinched between the cook-top and the
counter cutout, and press in place so that
cook-top interlocks with rails.
Note: If installing on a tiled counter top, seal the
tile joints with silicone rubber.

Final Check List
To prevent improper connection leading to damage
of electrical components and so voiding the
warranty, the following steps must be performed:
1. Check the electrical requirements and make
sure you have the correct electrical supply and
that the cook-top is properly grounded.
2. Make sure all control knobs are in the off
position.
3. Turn on the power supply to the cook-top.
4. Check power at jnnction box wires using a
volt meter having a range of 0-250 VAC. The
voltage reading between the black and red wires
(Line to Line) should be 220 to 240 volt when
connected to 240 volt supply or 190 volt to
208 volt when connected to 208 volt supply.
5. Depress and rotate each control knob to the
number "9" position. Observe indicator lights

to assure they are working.
Note: The residual heat indicators must be

heated to temperature before they glow.
Touching a heated cooking surface
could result in a serious burn.
46. If the cook-top is operating properly rotate
each control knob to its off position and turn
off the power supply to the cook-top.
7. Place cover on the junction box and make sure
cover is securely fastened and turn on the
power to the cook-top
8. If there is going to be some time before the
owner uses the cook-top. It is recommended
that, after waiting for the cook-top to cool, that
a sheet of packing be placed over the cook-top
to protect the surface from damage prior to use
by the owner.
9. Leave these INSTALLATION
instructions as
well _tsthe OPERATING Manual with the
owner.
