The control panel for the NEMCO 9121A-1 includes the following features:

• Display: Shows power levels, time, and error codes.

• Power On/Off: The main power button to turn the unit on and off.

• Start/Stop: Starts or stops the cooking or warming cycle.

• Mode: Button to switch between modes (not available on all models).

• Min/Sec: Button used for setting the timer in minutes and seconds.

• Timer: Button to activate the timer setting function.

• Multi-Purpose Knob: Used to adjust power levels and timer settings.

• The NEMCO 9121A-1 will not operate without an appropriate pan or vessel in place on the cooktop. After a few seconds, the display will flash ‘00’ indicating that no pan is present. If the pan is removed during cooking, the unit will turn off after about 40 seconds and the display will show ‘00’. Resume cooking by placing the pan on the cooktop and pressing the ‘Start/Stop’ button.

• If the temperature of the cooktop reaches 260° C or 500° F, the unit turns off automatically and displays an error code. This can happen if a pan is empty or is allowed to boil dry. Allow the unit to cool off. Restart by pressing the power on/off button.

• If the voltage or current in the device is abnormal it will shut itself off and display an error code.

• Small objects such as a knife or spoon will not be ‘seen’ as a valid pan by the range and it will not operate, however, do not place items other than induction cookware on the range surface.

1. Plug the unit into the appropriate power outlet. The display will show four red dots when voltage is present.

2. Press the red power on/off button. The display will show ‘00’ and the unit is now in the ready state.

3. Place an appropriate pan on the glass cooktop, centering it on the target.

4. Press the ‘Start/Stop’ button. The display will show ‘5’ or ‘6’, and the fan will start. The range is now warming or cooking at the displayed power level.

5. Rotate the knob to the right to increase the power setting.

6. Rotate the knob to the left to decrease the power level.

7. For the NEMCO 9121A-1, the power will adjust from H1 to H7 and 1 to 10. Power levels H1 thru H7 are hold settings, designed to keep food warm at a constant temperature for serving. Power levels 1 thru 10 are for cooking. The unit will continuously deliver power at that setting, similar to a gas flame setting.

8. While cooking or warming, press the ‘Start/Stop’ button to stop the cooking cycle, or remove the pan. If the pan is removed and replaced within approximately 40 seconds while the ’00’ symbol is flashing on the display, the system will automatically resume heating at the previous setting. After 40 seconds with no pan, the display will show a steady ’00’. Pressing the ‘Start/Stop’ button once will resume operation at the previous setting if the pan is present.

9. The power level can be adjusted ‘on the fly’ at any time while the unit is heating.

10. When the unit is turned off using the Power On/Off button, the cooling fan may continue to operate for a short period of time.

11. Do not unplug the unit until the fan has stopped running.

The ‘Best’ Power Settings will vary depending on the range model number, the type and shape of the pan being used, as well as the type and quantity of food being cooked or held. Until you get a ‘feel’ for the unit, you should start at medium settings of 5 or 6 and adjust up or down from there to get the performance you want.

For the NEMCO 9121A-1, you can use the following as a starting guide:

1. Stir Fry: Quickly stir fry on high heat settings of 8 to 10.

2. Boil Water: Boil water on high heat settings of 9 or 10, then reduce to level 5 or 6 to maintain a hard boil. Reduce to 3 or 4 for a slow boil.

3. Pan Fry: Pan fry on medium to high heat settings of 5 to 10.

4. Sauté/Simmer: Use medium to low settings 3 to 5.

5. Warming: Hold food at serving temperatures using setting 2. Results will vary depending on the volume of food being held.

6. Chocolate Melting: Use setting 1.

The following chart shows an approximate temperature guide for the warming units. Results will vary depending on the type of pan, and the type and volume of food being held.

Temperature control mode is not available on this model. If you press the ‘Mode’ button the display will show ‘000F’, but it will have no effect on the operation of the unit. Pressing the ‘Start/Stop’ button in this mode will result in an ‘E5′ error message after a few seconds. Press the red ‘Power’ button to turn the unit off and clear the error message.

The timer function allows you to set a timer from 1 second up to 719 minutes. The timer resets to 719 minutes every time the power is turned off/on. The timer always runs in the background, so if the unit runs continuously for 12 hours (719 minutes), the timer will run out and the unit will turn off. To reset, turn the power off/on, or manually set the timer.

Setting the Timer

• With the unit powered on and in the Ready state (display shows a steady ’00’), press the ‘TMR’ button. The display will show ‘0719’.

• To change the timer setting, press the ‘MIN/SEC’ button. The display will flash ‘719’.

• Turn the knob to adjust the number of minutes. Turning the knob to the left will reduce the number of minutes. If you turn the knob to the right past 719, the display will go to ‘00.59’ or 59 seconds. Keep turning to the right to increase the minutes.

• If you want to set seconds, for instance 3 minutes and 30 seconds, turn the knob until the display shows ‘03.59’ minutes. Then press the ‘MIN/SEC’ button again. The ‘seconds’ field will flash. Use the knob to adjust the seconds to 30. The display will show ‘03.30’.

• When the time is set to what you want, press the ‘Start/Stop’ button. The power will come on and the timer will count down. When the timer counts down to 0, the unit will stop heating.

• While the unit is heating, the display will alternate between the timer and the power setting. You can always adjust the power setting while the display is showing the power level.

• If you press the TMR button while the unit is heating, the display will stop alternating between the timer and the power level. The timer will continue to run. Pressing the TMR button again will resume alternating the display.

• While the unit is heating, the timer display decimal points will flash.

• Once the timer counts down to zero, pressing the ‘Start/Stop’ button will restart the cycle at the time that you set previously. Turning the unit off/on using the ‘Power’ Button will reset the timer to 719 minutes.

After the induction range has cooled down, clean as follows:

Glass Cooktop: Wipe with a damp cloth or use a mild, non-abrasive cleaning solution.

Control Panel: Wipe with a damp cloth only. Do not spray with cleaning solutions! Do not use sharp or metal objects to press the buttons! Only press the buttons using your finger!

DO NOT USE SHARP OBJECTS OR ABRASIVES ON THE GLASS COOKTOP. SCRATCHES IN THE GLASS CAN WEAKEN IT AND LEAD TO BREAKAGE!

Cooking with the NEMCO 9121A-1 requires the use of induction compatible pots/pans. In general, this means that the vessel must be magnetic. If a magnet sticks to it, it will probably be a good induction pan.

Other things to consider are the size and shape of the pan:

• Pans should have a minimum bottom diameter of 4.75 inches.

• The bottom of the pan should be flat within about 1/8 of an inch.

• For best results, the maximum bottom diameter of the pan should not exceed 10.25 inches.

Materials that will NOT work with induction ranges include glass, ceramics, earthenware, bronze, copper, aluminum or 300 series stainless steel.

To test a pan to see if it is compatible, put it on the range, press the Start button and increase the power level. If the display flashes ’00’, the pan is not compatible with induction cooking.

Always ensure that the glass surface of the range is mounted FLUSH with the countertop. The exposed edge of the glass is fragile and can be easily chipped or broken by side impact.

If flush mounting is not feasible, you can purchase the optional Stainless Steel Trim Ring this allows you to make a simple cut-out in the countertop, and the Trim Ring supports the unit and protects the glass edge from damage.

With either mounting method, seal around the unit (and Trim Ring) with silicone caulking to keep liquids from penetrating and getting below the surface.

If the units are mounted in a closed cabinet, you must ensure that there is adequate air flow for the units. Each unit draws in cooling air from the back, and exhausts warm air from the front. In a closed cabinet you must provide adequate openings for both the intake and the exhaust air.
