2. IMPORTANT SAFETY INSTRUCTIONS
This manual provides essential information for the installation, operation, cleaning, and maintenance of CookTek Helios
freestanding and drop-in induction cooktops and woks, including single-hob, double-hob, and wok configurations in both
Standard and Touch models. This document ensures the equipment is used correctly, safely, and in accordance with
applicable regulatory, electrical, and commercial kitchen standards. Information and specifications are subject to change
without notice. Retain for future reference.
WARNINGS:
• When operating this oven, strictly adhere to the following safety precautions to reduce the risk of burns, electric
shock, fire, injury, or damage to the cooktop or property near the cooktop.
• This appliance has hot surfaces! During use, the accessible parts of the cooktop can become very hot.
2.1 General Safety Information
Each installation site has unique electrical wiring. Since numerous local codes may apply, it is the owner's and installer’s
responsibility to comply with them. CookTek is not liable for any consequential damage resulting from failure to meet
installation requirements.
• Always unplug the appliance immediately after use and allow for cooling time if handling, transporting, or
storing.
• Turn off the cooktop/wok after each use.
• To disconnect the appliance, turn off the unit completely by pressing the power button, pressing Power Off,
then removing the plug from the outlet.
• Never heat empty cookware. Doing so may damage the unit or the cookware or cause it to overheat.
• If overheating happens, an error code will flash on the display, and the unit will shut itself off automatically.
When the temperature returns to normal, the unit can be used again.
• If the power is ON, the appliance will heat continuously. The cookware will be hot; exercise caution when
working on or near the appliance.
• Drop-in CookTek cooktops and woks come with a stand-alone (not built-in) control box for unit operation. Use
ONLY the control box that comes with the unit to avoid any possible operational hazards.
• The cooktops/woks are designed to work with CookTek's recommended induction-compatible cookware only.
• Users wearing a pacemaker should consult their doctor or the pacemaker manufacturer prior to operating
CookTek induction equipment. The electromagnetic field may interfere with the pacemaker's proper function.
• Metallic objects such as kitchen utensils, knives, spoons, etc., should not be placed on the appliance. Use
caution when wearing rings, watches, and other metallic objects, as they may get hot if placed near the unit’s
surface.
• Remove the cooktop carefully from the carton.

• Remove all loose packaging and accessories and keep them for future shipment or in case of concealed
shipping damage.
• Any installation that does not follow the specifications outlined in this manual automatically voids the product’s
warranty.
• CookTek requires a dedicated electrical line to be used for each cooktop installed.
• Electrical circuits should not be shared with any other electrical equipment.
• Maximum allowable line voltage is 132 VAC for 100–120 VAC units, 265 VAC for 200–240 VAC units, and 430
VAC for 380–415 VAC units. Exceeding these limits may damage the equipment.
• Always provide a dedicated electrical circuit for the equipment.
• Place the unit on a dry, level, rigid, stable, and non-flammable surface.
• Keep the unit away from other heat sources.
Note: Refer to the Spacing Requirements section for spacing and clearance information for all cooktop units.
• Review the Cleaning and Maintenance section if your unit is equipped with a grease filter on the bottom.
• All units should be checked for build-up and debris around the intake and exhaust vents on the bottom of the
unit.
• Unplug the unit and clean any debris from the vents with a dry cloth to ensure proper airflow to the equipment.
DO NOT perform the following:
Use the cooktop/wok surface for storage purposes
Use the cooktop/wok for anything other than its intended use as described in this manual. This unit is
designed to heat food and is not intended for laboratory or industrial use
Use any accessories or attachments that the manufacturer does not recommend. Use of unapproved
accessories may cause injuries and void the warranty.
Use any appliance that has a damaged cord or plug, or one that has malfunctioned or been damaged.
Let the power cord touch hot surfaces or hang over the edge of the counter.
Move the appliance when electric power is connected.
Immerse cords, plugs, or the appliance in water.
Put food or unopened cans on the cooktop/wok surface.
Leave the appliance unattended while in use.
Place aluminum foil or plastic objects on the cooktop/wok surface.
Use the cooktop/wok near a faucet, swimming pool, sink, or other areas where water can be found. Never

2.2 Air Flow and Ambient Temperature
• Avoid ambient temperatures exceeding 122 °F (50 °C).
• For drop-in units, the following minimum airflow must be provided:
o Single units require a minimum of 70 CFM (2.0 m3/min) of fresh air to the unit
o Double units require a minimum of 140 CFM (4.0 m3/min) of fresh air to the unit
2.3 Reducing Fire Risk
• In the unlikely event of a grease fire, smother flame by covering cookware with a tight-fitting lid, cookie sheet, or
flat tray. DO NOT USE WATER. When the fire is under control, turn off the appliance and unplug it from the wall.
• Keep the cooktop/wok away from metallic surfaces, gas and electric ranges, and open flames.
2.4 Warranty
Visit cooktek.com/warranty-service for CookTek Warranty information.
• This product may only be serviced by an authorized service agent or by CookTek personnel. Do not attempt to
open the unit or perform any service. For service information, contact CookTek at +1 (214) 379-6000.
• Throwing or dropping the unit can damage the internal components or crack it, voiding your warranty.
• If the cooktop/wok becomes cracked, unplug the unit immediately and do not use it
2.5 Grounding Instructions
The cooktop must be properly grounded. In the event of an electrical short circuit, grounding reduces the risk of electric
shock by providing a safe path for the electric current to flow. The cooktop has a power cord with a 3-prong grounding
plug, which must be used in a compatible and properly grounded outlet. It is the owner’s responsibility to replace any 2-
prong wall outlet with a properly grounded 3-prong wall receptacle. For your safety, never cut, remove, or disable the
electrical (ground) connection from the plug. Never use an adapter plug or an extension cord with the cooktop.
WARNING: Improper grounding can result in risk of electric shock.
Some units may come equipped with a removable IEC power cord. Ensure this power cord is firmly attached to your
CookTek unit before plugging the unit into the power receptacle and attempting operation.
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.

2.6 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 oven is unplugged during service or maintenance, the user must be able to always access and see
the plug to ensure that the oven remains unplugged. The plug must remain near the oven and cannot be placed behind
another appliance or in another room.
2.7 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.
2.8 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.
2.9 Approved For Commercial Use
CookTek Helios induction appliances are certified to UL 197 and CSA C22.2 commercial cooking standards and comply
with applicable requirements of the European Economic Area (EEA), bearing the CE mark to indicate conformity. These
certifications confirm that the equipment is approved for commercial food service applications.

3. SPACING REQUIREMENTS
• All units require a minimum clearance of 2” (51 mm) between all sides of the housing and any surface or obstacle.
If
Then
The unit is being placed near a grill or stove
A divider must exist between the unit and the open heat source,
with a minimum of 6” (153 mm) between the unit and the divider.
The unit is placed near a fryer
A divider must exist between the unit and the fryer, with a
minimum of 12” (305 mm) between the unit and the divider.
• All drop-in units require a minimum clearance of open space below the unit of 6” (152 mm). The space must have
openings that allow cool air (ambient temperature not to exceed 122 °F (50 °C)) to flow to the cooktop housing
intake vents. If either the air intake or the exhaust outlet is blocked, the internal temperature will rise, triggering an
error code.
Note: The 6” (152 mm) can be reduced if additional fans and ducting are added to provide forced ventilation.
• Do not install the unit near other equipment that generates excessive heat or grease that can be pulled into the
CookTek unit by its fan (i.e., griddles, fryers, etc.).
• Do not place the unit near items that generate excessive steam that can be pulled into the CookTek unit by its fan
(i.e., pasta cookers, steam baths, dishwashers, etc.).

5. DROP-IN COOKTOP AND WOK INSTALLATION
1. Cut out and drill holes as required in the countertop.
2. Drill holes for control box mounting.
3. Apply a bead of an NSF Standard 51-approved
sealant (such as Dow Corning 732 Multi-Purpose
Sealant or GE RTV 108) around all four edges of the
countertop cutout.
Note: Carefully follow the sealant manufacturer’s
instructions to ensure proper adhesion.
4. Place cooktop or wok over countertop cutout.
5. Pass the control panel and cord through the cutout,
then pass the base of the cooktop or wok through
the hole until the flange rests on the countertop.
6. Mount the control panel using the screws supplied.
Note: Mounting options are illustrated in the attached
drawing.
7. Connect the cooktop or wok to a grounded 120 VAC
or 200–240 VAC single-phase receptacle, or to a
380–415 VAC three-phase supply for applicable
models.
8. Check the rating plate on the cooktop or wok to
verify the correct voltage.
Note: For proper operation, a dedicated circuit should
be used for each unit installed. Each circuit should be
protected with a 20-amp minimum circuit breaker. For
optimal operation, the counter should have an
opening near the unit to allow fresh air to circulate
beneath it.

6.1 Power Mode
Your CookTek cooktop has two different cooking modes:
Temperature Mode and Power Mode. Woks only operate
in Power Mode.
• Connect the cooktop to a grounded power
source. Models operate on 100–120 VAC (up to
1800 W), 200–240 VAC (up to 3500 W), or 380–
415 VAC three-phase (up to 3500 W), depending
on the model. Refer to the rating plate to verify
the correct voltage and wattage. Operating
below the rated voltage may reduce power and
slow heating.
Note: For proper operation, use an independently
dedicated circuit for each installed unit. Each
circuit should be protected with a 20-amp
breaker. When your application requires high-
intensity heat or a quick temperature rise, activate
the Power mode.
• Turn the cooktop ON by turning the control knob
to the right.
• Press the Temperature/Power button briefly.
• Turn the control knob until the desired Power
setting (1-20) appears on the LED display.
• Turn the control knob to the left to decrease
power and to the right to increase power.
• To turn off the cooktop or wok, rotate the
control knob all the way to the left until it clicks,
and the LED display turns off.
Notes:
o You can switch between Temperature
Mode and Power Mode at any time by
pressing the Temperature/Power button
(cooktops only).
o The internal cooling fan may operate briefly
after the power supply has been
disconnected. This behavior is typical and
should not be a cause for concern.

6.2 Helios Standard Cooktop - Temperature
Mode
When the recipe requires maintaining a precise, even
temperature for a set period, Temperature Mode is
recommended. Woks only operate in Power Mode.
Note: Temperature Mode monitors the temperature of the
bottom of the pan. For the actual temperature of the food
contents, a contact thermometer should be used.
• Turn the cooktop ON by turning the control knob
to the right.
• Put the cookware with ingredients on the
cooktop.
• Press the Temperature Mode button.
• Turn the control knob until the desired cooking
temperature appears on the LED display.
Note: The displayed temperature will change
from the set temperature to the measured
temperature three seconds after the control knob
is moved. The LED will display the measured
temperature until the target temperature is
reached.
• To turn off the cooktop, turn the control knob to
the far left until it clicks, and the LED display
turns off.
Note: If the unit is left on and unattended for five
or more minutes without a pan on its surface, it
will automatically enter Sleep Mode to save
energy. You can tell it's in Sleep Mode because
the LED shows horizontal dashes. To resume
normal operation, rotate the power knob
clockwise or counterclockwise.
6.3 Helios Standard Wok Operation
Wok operation is similar to using a standard cooktop, with
just a few minor differences.
• Use the control knob to select a relative cooking
level, which will indicate a setting ranging from 1
(lowest setting) to 20 (highest setting).
• DO NOT leave any unattended pans on the wok.
• Turn the wok off when not in use.
• Do not place an empty pan on the wok. This can
cause the pan and the unit to overheat,
potentially damaging the unit.
• This wok unit is intended for use with 14”
induction-compatible wok pans. Using smaller
pans may result in frequent nuisance errors and
automatic precautionary shutdowns.
