Motor Installation
 Always disconnect electrical power at the fuse box or circuit breaker panel before handling electrical
connections or performing maintenance on this unit. Allow the motor to come to a complete stop and wait
four (4) minutes. This allows the capacitors to discharge any residual voltage for safety.
 Double-check to make sure that electrical power is removed and that it cannot be turned on while you are
working on the equipment.
 A poor electrical connection can overheat and cause terminal and/or terminal board failures. Examine the
wiring harness quick-connect terminals carefully for any signs of physical deterioration or loose fit to the
terminals on the motor terminal board.
