4.3 Electrical Connection
The cooktop must be hard-wired directly to a fused disconnect box or circuit breaker. It does not come with a plug. Refer to the wiring diagram provided in Figure 7 for correct connections. It is strongly recommended that a qualified electrician perform the installation.
5. Operating Your Cooktop
5.1 Control Knobs
Each burner is controlled by a dedicated knob located on the right side of the cooktop. To activate a burner, rotate its corresponding knob from the "OFF" position to the desired power level (1-9). The indicator light next to the knob will illuminate when the burner is active.

Figure 8: Simple Knob Control. This image highlights the user-friendly knob controls, demonstrating how easily they can be adjusted, making the cooktop accessible for all users.
5.2 Power Levels
The 9 power levels allow for precise heat adjustment:
- Levels 1-2 (Low): Ideal for melting butter, keeping food warm, or gentle simmering.
- Levels 3-4 (Medium-Low): Suitable for slow cooking, simmering sauces, or reheating.
- Levels 5-6 (Medium): For general cooking, frying, and sautéing.
- Levels 7-8 (Medium-High): For rapid boiling, searing, or stir-frying.
- Level 9 (High): Maximum power for quick boiling or intense searing.
