3 Technical Descriptions

3.1. Description of operating sequence

Variable power cooking control

The coil of power relays are energized intermittently by the digital programmer circuit, when the oven is set to MEDIUM or DEFROST power position. The digital programmer circuit controls the ON-OFF time of each power relay contacts in order to vary the output power of the microwave oven. One complete ON and OFF cycle of the power relay is 44 seconds. The relation between indications on the control panel and the output power of the microwave oven is as shown in Figure.

5 Installation Instructions

5.1. Wiring requirements and power source voltage selection

Wiring Requirements

No other appliance should share the circuit with the microwave oven. If it does, the branch circuit fuse may overload and either cause the oven to heat slower than expected or blow the fuse.

1. For Mode NE-12521/NE-12523/NE-1252 The oven must be on a SEPARATE, 20 Amp, 60 Hz-120V GROUNDED CIRCUIT.

2. For Model NE-1752/NE-1772/NE-17521/NE-17523/NE17723 This oven must be on a separate, 60 Hz GROUNDED CIRCUIT-minimum 15 amps.

3. For Model NE-21521/NE-21523/NE-2152 This oven must be on a separate, 60 Hz GROUNDED CIRCUIT-minimum 20 amps.

Power Source Voltage Adjustment

For 208V/230V models The microwave oven automatically detects 208 V and 230 V-240 V. Insert the plug, and if the Digital Display Window goes blank 10 seconds after use, unplug and insert the plug again.

6 Operating Instructions

6.1. Operation procedure

1. Manual heating for single stage 2. Manual heating for 2nd or 3rd stage
