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.

the motor start board or junction box.

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