Note:

DO NOT plug in range at this time.

The Four Wire Connection is preferred, but where local codes and ordinances permit grounding through neutral and/or conversion to four wire is impractical, unit may be connected to the power supply via a three wire connection.

1.Disconnect electrical power at the breaker box.

2.Remove the terminal block cover to expose the terminal block.

4. Remove the TOP nut, star washer, and round washer from each post.

Note:

DO NOT remove last round washer, last nut or internal wire leads.

5.Place one terminal lug (packaged with this manual) on each post. Replace the star washer and round washer and secure with 20 inch pounds of torque.

6.Strip 3/8 (9.53 mm) inches of insulation from the end of each wire.
