Operation Principle - First fa-5095 User Manual

User's ManUal oF electroMagnetic oven
i. operation principle
230V AC power converts to HF current through circuit. The HF current generates alternating magnetic field
through induction coil. Then the magnetic field penetrates the face plate to make force on the bottom of pan
to generate magnetic field vortex that overcomes the internal resistance flow of the pat bottom to generate
joule, converting power energy to heat energy.

Ⅳ. operations and key-press FUnctions
initial operation
1. Standby mode: After you have connected the device's plug to the main supply, the induction cooker is in
standby mode.the power indicator lighter flashes.
2. Put a suitable pot on the cooking zone.
3. Push the "ON/OFF" button to start the cooking process.
4. Use funtion buttons to select the desired cooking function.

cooking function
1. on/off button: Once being electrified, the power supply indicator light would blink and the buzzer would
buzz which indicates the electric magnetic stove has been electrified. The electric magnetic stove would
go to the standby mode if the on/off button is pressed. While in the standby mode, the electric stove would
immediately start working according to the selected function if any functional button is pressed. If the
on/off button is pressed for one time, the electric stove would stop working and go back to the electrified
mode no matter in what mode it is. Meanwhile the fan will continue to disperse heat according to the
internal temperature in the machines.
2. "+" and "-" adjustment button: Under the working modes, the adjustment button is responsible for
adjusting firepower and temperature.
3. timer mode: in the working modes, press the timer button for one time, the timer indicator light would
blink, and the time display of the digital tube is zero. Press the "+" and "-" button again to set the turning-
off time between 1 to 120 minutes which would be shown in a countdown way.
4. timer cancel: in time modes, press "Timer Cancel" buttom, the timer that set before will be cancel, the
timer indicator light would dark.
v. selection and Use oF oven tools
1. Suitable oven tools and containers: iron series (enameled, cast and stainless irons) with plain and smooth
bottoms with diameter of 12-22cm.
2. Unsuitable oven tools and containers:
A. Containers and pans made of aluminum, copper, ceramics and glass etc.
B. Containers with bottom diameter less than 12cm.
C. Containers and pans with uneven bottoms.
vi. saFety protection devices
1. Power voltage over high and over low protection;
2. Surface over temperature protection;
3. Surface temperature sensor open-circuit protection;
4. Surface temperature sensor short-circuit protection;
5. No-oven-no-start-heating and closing protection
6. Automatic turning off protection without any operation order for 2 hours
7. Standby delayed heat radiation protection;
8. display of fault codes:
A. When fault occurs, digit tube displays fault code
B. List of fault codes
Code Fault
E1 Surface temperature sensor short-circuit protection
E2 Surface temperature sensor open-circuit protection
E3 IGBT over temperature protection
E4 Surface over temperature protection
E5 Power voltage over low protection
E6 Power voltage over high protection
vii. points For attention oF saFety
1. after used, the ceramic surface plate is still heat, so don't touch it for fear of scald.
2. Don't lay paper and cloth etc. on the surface plate for indirect heating for fear of firing caused by the
overheat pan bottom.
3. Don't collide with the nucleated glass plate. In case of breaking, turn off the oven and pull out the plus to
cut off the power and stop operation.
4. Don't use the oven near water for fear that the water would soil the oven to cause fault.
5. Don't heat can and other sealed stuffs for fear that the air in the can would inflate to cause explosion.
6. Don't let the oven close to the heat source like gas oven for fear that the gas heat would melt down the
rubber hull of the oven.
7. Don't heat with aluminum foil directly or indirectly for fear of danger.
8 Don't put credit card, IC, watch and radio set etc close to the oven for fear that the magnetic field would
impact them to cause cacophony.
9. Don't heat the empty pan.
10. Please use 10A/230V AC or 15A/230V AC sockets respectively.
11. The oven should be placed levelly and not pressed close to wall or other objects, keeping a distance no
less than 10cm to ensure ventilation.
12. Users with cardiac pacemakers can use this product only after the doctors confirm there would be not
impact through diagnosis.
