WARNING

INJECTION HAZARD

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, follow the Pressure Relief

Procedure on page 9.

NOTE: See Fig. 22 for this procedure.

1.Relieve pressure.

2.Remove the junction box screws (56) and lower the junction box (59).

3.Disconnect the motor wires (B) and the 3-wire connector (A) from the motor start board (47). Observe where connections are made.

4.Remove the screws (58) and motor start board

(47). Transfer the white thermal paste from the old board to the new board.

5.Install the new motor start board. Reconnect all wires. Install the junction box. Be sure no leads are pinched against the motor or by the motor start board. Also be sure the gasket (89) is installed.

CAUTION

Be sure the flat blade of the insulated male connec- tor is centered in the wrap±around blade of the female connector when the connections are made.

Route all wires carefully to avoid interference with the motor start board or junction box.

These precautions are essential to reduce the risk of a malfunction.

Power Supply Cord

NOTE: See Fig. 22 for this procedure.

1.Relieve pressure.

2.Remove the junction box screws (56) and lower the junction box (59).

3.Disconnect the power supply cord leads, including the green wire to the grounding screw (49).

4.Loosen the strain relief bushing (51). Remove the power supply cord (50).

5.Install the new cord (50) in the reverse order of disassembly.

6.Install the junction box. Be sure no leads are pinched against the motor or by the motor start board. Also be sure the gasket (89) is installed.

4.Disconnect the black wires from the ON/OFF switch (52) and remove the switch.

5.Place the ring terminal of the ground wire (53) over the barrel of the new switch. Install the switch so the internal tab of the anti-rotation ring (54) en- gages with the vertical groove in the threads of the switch, and the external tab engages with the blind hole (C) of the junction box.

6.Powder the inside of the rubber boot (55) with talcum, then shake the excess out of the boot. Install the nut and rubber boot and tighten.
