voltage coincides with the working voltage.
2. Plug in to connect the power supply, the green indicator will be on and the appliance is energized.
3. Rotate the thermostat clockwise, set desired temperature according to requirement. The yellow
indicator is on, the heating element starts heating and the temperatures of plates rise.
4. Temperature is adjustable according to food types. 180℃~250℃is recommended. It takes
about 8min to make the furnace temperature reach 250℃.
5. If the temperature reaches 250℃, lift the upper plate to proper position by the operating handle.
Then, coat the plates with edible oil and put the prepared food evenly onto the plates. Cover the
upper plate and press the handle lightly. Observing the grill condition at times till the food is ready,
which can be determined by operators.
6. When the temperature reaches preset value, the thermostat will cut the power supply off
automatically. The yellow indicator is off and the green one will be on, the heating element stops
working and prepare for the next grill circulation.
