5. Connect the wires to the terminal block inside the heater:
• Connect the Black Wire to L1.
• Connect the Red Wire to L2.
• Connect the Green Wire to the Ground terminal.
6. Ensure all wire connections are secure and that no insulation is under the terminals.
7. Tighten the strain relief to prevent the power cord from pulling out or being damaged.
8. Close the electrical access panel and secure it with the retaining screw.
