 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.
 If there is evidence of deterioration or loose fit, remove the quick-connect terminals from the wiring harness
and then connect the harness wires directly to the motor terminal board wiring terminals.
 Care must be taken to assure connections are made to the proper terminals and adequate electrical
clearances are maintained.
 The control unit on the motor contains hazardous voltage.
 Wear safety glasses to inspect the equipment while it is running or while working on equipment.
The motor and control unit are assembled and calibrated as a set. Replacing either the motor or control unit
with other unsuitable parts could drastically affect performance tolerance.
 To prevent permanent damage to the unit, only apply nameplate voltage.
 Do not apply 230 Vac to the motor when the motor is configured for 115 Vac operation. Refer to page 7.
 Do not strike the motor shaft with a hammer or other tool as this may damage the bearings.
 Do not operate the motor without the blower wheel attached. Without the blower wheel attached, the motor
will run continuously to a maximum speed and then stop.
 Voltage symbols vary among different multimeters and may be displayed as Vac, AC, V, or a V beneath a
wavy line. Select the correct symbol and set the multimeter to the voltage closest to but higher than the
voltage you are measuring.
