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.
Use only specially designed motors where explosive atmospheric hazards exist. See the
National
Electrical Code (NEC) Article 500
or check with local codes for explanation of hazardous or classified
L
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 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.
The RESCUE
®
Select Pro motor is properly packaged for shipment and storage and should be kept in a
clean and dry indoor area.
The motor should be stored indoors in a clean, dry location. Proper selection, installation, and maintenance
will assure longer life and more dependable service.
The RESCUE

Select
motor may is designed for direct-drive centrifugal blower applications only.
The RESCUE
®
Select
motor is designated for continuous, air-over duty, and must be mounted in the
air stream of an air moving device, such as a fan.
Do not
operate the motor outside of the air stream as
that may overheat and damage the motor.
