Use corrosive chemicals or vapors in this appliance; it is not designed for industrial/laboratory use.
Operate this appliance if it has a damaged cord or plug, is not working properly, has been damaged or dropped.
Refer to the Power Cord Replacement section.
Store this appliance outdoors or upside down.
Use this appliance near water (e.g., a kitchen sink, a wet basement, or a swimming pool).
Immerse the cord or plug in water.
Let the cord hang over the edge of a table or counter.
Place the cord near heated surfaces.
Use any accessories or attachments that the manufacturer does not recommend. Use of unapproved
accessories may cause injuries and void the warranty.
Move the appliance while it is plugged in or while a hot pan or a pan containing hot liquids is on top of the
appliance.

2.3 Grounding Instructions
This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by
providing a safe path for the current. This appliance is equipped with a cord that includes a grounding wire and a
grounding plug, which must be plugged into a properly installed and grounded outlet. Consult a qualified electrician or
service technician if you're unsure how to follow grounding instructions or have questions about whether the appliance is
properly grounded. It is the owner’s responsibility to replace any 2-prong wall outlet with a properly grounded 3-prong wall
receptacle.
WARNING: Improper grounding can result in risk of electric shock.
Do not use an extension cord. If the power cord is too short, have a qualified electrician or serviceman install an
outlet near the appliance.
2.4 Power Cord Replacement
If the power cord is damaged, it must be replaced by the manufacturer, its service agent, or a similarly
qualified person.
WARNING: If the Incogneeto™ is unplugged during service or maintenance, the user must always be able to access
and see the plug to ensure that the oven remains unplugged.
2.5 Protective Earth (Ground) Symbol
This symbol identifies the terminal intended for connecting an external conductor to protect against electric
shock in case of a fault, or the terminal of a protective earth (ground) electrode.
2.6 Equipotential Bonding Symbol
This symbol identifies the terminals which, when connected, bring the various parts of an equipment or of a
system to the same potential, not necessarily being the earth (ground) potential, e.g., for local bonding.

3. SPECIFICATIONS
Figure 3-1: Incogneeto Dimensions
3.1 Performance
The CookTek Incogneeto™ is an undercounter buffet
warmer designed to mount under natural stone or
“engineered” stone countertops – no cutting into the
stone is required. A Magneeto™ II trivet (included with
purchase) is placed on the countertop and acts as a
temperature sensor, communicator, and locator device,
enabling efficient heating of any induction-compatible
pan through the stone countertop.
Note: Induction buffet units require induction-compatible
cookware (i.e., magnetic).

4. INSTALLATION
Install or position this appliance only as directed below.
Note: Installing the product without following the
specifications in this manual will void the warranty.
4.1 Important Characteristics of Natural
Stone
Natural stone contains inherent variations and
flaws. Cracking may occur due to:
• Insufficient structural support
• Shifting or uneven cabinet joints
• Uneven weight distribution
• Localized temperature differences
Heat sources that may contribute to localized
stress include:
• Heat lamps above the surface
• Equipment installed below the stone
• Hot cookware placed on the surface
CookTek testing shows that natural stone neither
affects wireless signals nor absorbs induction
energy from Incogneeto™ or Magneeto™ II devices.
4.2 Design Considerations
• Cabinet ventilation must maintain interior
temperatures as close to room temperature as
possible. Poor ventilation increases stress on
the stone.
• Stone strength increases with thickness.
o A 1.2 in (30 mm) stone offers increased
crack resistance and better heat
dissipation.
o A 0.8 in (20 mm) stone has reduced tensile
strength and is more vulnerable to stress.
• Provide as much surrounding stone surface
area as possible around the Incogneeto™
opening to improve structural integrity.
• Avoid mechanical seams in cabinet supports
near the Incogneeto™ installation area.
• The Incogneeto™ units can be installed side by
side without requiring extra cooling space.
However, the serving vessel on top may restrict
side-by-side setup.
4.3 Best Practices for Installation Under
Natural Stone
For assistance, contact customer service at
214-379-6000 (Option 1) or
customerservice@cooktek.com
• A 1.2 in (30 mm) natural stone is
recommended for high-use applications.
• A 0.8 in (20 mm) engineered stone is
acceptable for all applications.
• A 0.8 in (20 mm) top (any material) requires a
plywood substrate.
• Maintain a minimum of 8 in (203 mm) of stone
from the edge of the Incogneeto™ cutout to any
finished stone edge.
• Use caution with overhead heat lamps. Heat
lamps can damage Magneeto™ II trivets if no
cookware is present to absorb the heat.
• Metals should not be used directly above an
installed Incogneeto™ unit in countertop
construction, although trace metals in the
stone or engineered stone are permitted.
Metals in cabinet construction may cause
heating or interfere with communication
between the Magneeto™ II and Incogneeto.

4.5 Unpacking
1. Remove the Incogneeto™ from its packaging.
2. Before discarding, check the packaging
thoroughly for accessories and literature.
Note: Keeping the packaging is recommended in
case the buffet warmer may be shipped to
another location.

4.6 Mounting
CAUTIONS:
• Keep the unit away from other heat
sources.
• Leave at least two inches of space on the
sides, front, and rear for air circulation.
Blocking either the air intake or exhaust
outlet will cause the internal temperature
to rise, which may trigger an error code.
1. Measure the countertop thickness where the
unit will be installed.
IMPORTANT: Do not measure the decorative
edge of the countertop if it is thicker. Some
countertops have a thicker edge that does not
reflect the actual surface thickness.
Note: The top of the unit must be 1.5–1.65 in
(38–42 mm) from the top of the counter.
2. Glue plywood or plywood strips to the stone
countertop.
If
Then
Using a 0.8 in
(20 mm) stone
countertop
A 0.8 in (20 mm) plywood
sheet must be installed.
Using a 1.2” (30

A 0.5-in (12-mm) plywood
sheet must be installed.
OR
Two 0.8 in (30 mm) strips
must be installed.

3. Attach the mounting frame to the plywood or
strips with 0.5 in (12.7 mm) wood screws.
4. Snap the Incogneeto™ into the frame place.
Note: Install the unit so that the ANTENNA SIDE
sticker is under where the Magneeto™ II RFID tab
will be located.

4.7 Installation Tips
Example 1:
The Magneeto™ II RFID tab must be positioned
over the antenna side of the unit. The antenna runs
the entire length of the unit, allowing the
Magneeto™ II to be used in the 3 or 6 o'clock
positions.
Example: Island Installation
Mount units with the antenna side facing the
guests. The Magneeto™ II RFID tab must be over
the antenna side. Magneeto II can be used with the
LED indicator in the 3 or 6 o’clock position, facing
the servers and not the guests. Servers can see
that the system is working and the guests are not
distracted by the lights.
Example 3: Flush with Wall
Mount units with the antenna side against the wall. The
Magneeto™ II RFID tab must be over the antenna side.
Magneeto II can be used with the LED indicator in the 3 or 6
o’clock positions. The 3 o’clock position avoids the lights
shining directly at seated guests, but servers can see that
the system is working.

5. CLEANING
5.1 Incogneeto™ Buffet Warmer
Turn the unit off and remove the plug from any
power outlets before cleaning.
CAUTION: Never immerse the buffet in water or
put it in the dishwasher.
5.2 Magneeto™ II
• Clean the Magneeto™ II with a mild soap or

Notes:
• Models will operate on 100–120VAC drawing up to
650 W, or on 200-240 VAC drawing a maximum of
650 W. Check the rating plate on the unit to verify
the correct voltage and wattage. Voltages below
120 VAC or 240 VAC may result in reduced power
and slower heating times.
• This unit requires a Magneeto™ II for operation.

1. Press the POWER button to turn the
Incogneeto™ on.
Note: The green LED beside the POWER button
will light up.
2. Place a Magneeto™ II on the countertop and
slowly slide it until the LED starts flashing and
the SmarTag™ LED lights up.
Note: The best position is where the light flashes
brightest.
3. Place an induction-compatible dish on the
Magneeto™ II, making sure it covers the
temperature sensor.
Notes:
• Do not cover the RDIF tab with the dish.
• The Pan Detect LED will illuminate.
• The unit will begin to warm up to either 80
°F or the latest temperature entered.
4. Press the up and down arrows to select the desired
preset temperature options.
