Install Instructions

After opening carton, look for damage. If damage is found file a claim with the
freight carrier. The motor shaft should rotate freely by hand. Verify that the
carton and nameplate data match the motor you bought.
Storage
Motor should be stored indoors. The chosen location should
be clean and dry.
General Information
This is a single-phase permanent split capacitor (PSC) motor designed for use as a
condenser fan motor. Do not use this motor in the presence of spraying or
standing water. This motor is suitable for use in Class III locations where airborne
lint or fiber is present, as defined in article 500 of the National Electric Code
(NEC). This motor is not suitable for use in Class I or Class II (explosive gas or
dust locations). This motor is a continuous air over motor. For suitable operation,
it must operate in the air stream of the furnace. This air stream helps cool the
motor.
Power Source
Supply voltage and frequency must match what is shown on the motor nameplate.
Source voltages lower than rated supply can reduce performance and cause the
motor to overheat.
Motor Protectors Voltage
Wagner strongly urges the use of a line voltage monitor (similar to Wagner model
DSP-1). These devices measure and monitor supply voltage, and if it ranges too
high or too low, the motor circuit is “turned off” through the contactor circuit.
Motor Installation
All aspects of the installation must conform to requirements of the NEC, and any
applicable local codes. The supply circuit must be of adequate capacity to maintain
sufficient voltage during start and run periods. Supply wire size must be of
adequate gauge to carry current as required by the motor. All electrical
connections must be secure to prevent voltage drop and localized heating.
Motor Mounting
This motor must be mounted securely to prevent vibration and reduce noise.
Motors with sleeve bearings should be mounted so oil ports are readily accessible.
This motor has removable condensate drain plugs in the motor end plates shaft
end and wire end. As the motor can be used in any shaft vertical orientation
(shaft up or shaft down), the removable condensate drain plug on the BOTTOM
side of the motor should be removed at installation.
Do not strike the motor shaft. This may damage the bearings or other internal
components.
Motor Electrical Connection
Motor must be securely and adequately grounded with a method approved by the
NEC and local codes.
Insulate all connections to prevent grounding or short circuits.
Reinstall all conduits, terminal box covers, and other electrical devices. Do not
force connections.
Wagner recommends the replacement of the capacitor with this PSC motor. Be
sure the replacement capacitor matches the rating requirement on the new
motor.
The power supply must have fuses to provide short circuit protection as required
by local codes.
Any switching device used to control the motor must have a rating at least equal
to the new motor.
This motor is NOT designed for electronic speed control. DO NOT connect this
motor to an electronic speed control.
Starting Motor
Be sure the motor is properly grounded. Remove any mechanical locks in the
motor shaft or mechanically connected components. Start the motor briefly.
Make sure the motor is rotating in the correct direction. Make sure the motor is
not creating any unusual noises or vibration. Check the motor's current draw. It
should be within ten-percent of the nameplate rating. As this motor is an air
moving motor, all enclosures must be in place to take an accurate amp reading.
Motor Operation
Visually re-inspect the installation. Make sure all guards, housings, and other
protective devices are in place. All covers and gaskets must be re-installed to
minimize the introduction of dirt and moisture. The external case of the motor
becomes hot enough to cause injury during normal operation. Use caution when
working near an operating motor.
Motor Maintenance
Always disconnect power and allow the motor to completely stop and cool before
performing maintenance. Discharge any capacitors for safety. Periodically inspect
the motor installation to assure it is free of accumulated dirt. Also be sure the
motor is free of unusual vibration and noise. Remove dirt accumulations by
vacuuming any debris. Do not use solvent cleaners. Ball bearing motors are
permanently lubricated. Sleeve bearing motors require periodic re-lubrication. Do
not overlubricate.
