Page 3: Important Safety Information
Important Safety Information WARNING SHOCK HAZARD To reduce the risk of fire or electric shock: • Do NOT expose the motor or control unit to rain or moisture. • Do NOT separate the motor and control unit while the motor is in operation. WARNING 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 atmospheres and locations. Unless the motor is specifically marked “ELECTRIC MOTOR FOR HAZARDOUS LOCATIONS,” it is not suitable for use in Class I or II hazardous locations as defined by the NEC. • Only trained and qualified professionals familiar with ECM products should install or ervice the motor and control unit. • Before connecting or disconnecting cables or other electrical connections, verify that the power to the system is removed. Failure to comply may cause serious damage to the motor or HVAC system or injury to personnel. • Because of the risk of electric shock, only individuals thoroughly trained in the use of multimeters should conduct voltage tests. • Never touch the metal contacts on the multimeter during a test. • For air moving applications, all enclosure covers and panels must be in place before measuring the amperage. • Always check testing equipment for proper operation before use. - Page 4 WARNING • Installation, operation, and maintenance must be performed by qualified personnel. Familiarization with and adherence to the NEC, National Fire Protection Association (NFPA) standards, and to local codes are required. It is important to observe safety precautions to protect personnel from possible injury. Personnel should be instructed with respect to handling each of the following: • All aspects of the installation must conform to the applicable requirements of the NEC, including Article 430 (Motor Circuits and Controllers), as well as all local codes. • Make sure the unit is electrically grounded and that proper electrical installation wiring and controls are used consistent with local and national electric codes. Refer to NEC Handbook and NFPA No. 70. Employ qualified electricians. • Code requirements differ from state to state. Install equipment using qualified electricians in accordance with the applicable codes and ordinances in your area and in accordance with NEC. All electrical connections should be made and maintained by a qualified or licensed electrician. • Insulate all connections carefully to prevent grounding or short circuits. Reinstall all conduit and terminal box covers. To avoid overheating or loss of performance, voltage to the motor control unit must be within plus or minus 10% of the nameplate voltage. • Avoid contact with energized circuits or rotating parts. • Provide proper safeguards for personnel against rotating parts. • Make sure there are no unusual noises or vibrations when the motor is running. • 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. Double- check to make sure power is OFF, and that it cannot be turned ON while you are working on the equipment. Wait 4 minutes before handling the motor or wiring harness. This allows the bus capacitors to fully discharge. • 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 between the motor and unit connections. • Care must be taken to assure connections are made to the proper terminals and adequate electrical clearances are maintained.
- Page 5 CAUTION FLEXPSC61 ECM Condenser Fan Motor may look visually different from the motor it is replacing. The FLEXPSC61 ECM Condenser Fan Motor is designed as a replacement for PSC and ECM condenser fan motors. The motors external appearance is not an exact replica of the motor it is replacing; however, when properly installed, FLEXPSC61 ECM Condenser Fan Motor will fit in the fan unit housing and function according to specifications. • The FLEXPSC61 ECM Condenser Fan Motor is designed for direct-drive outdoor condensing unit applications. • FLEXPSC61 ECM Condenser Fan 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 FLEXPSC61 ECM Condenser Fan Motor outside of the air stream as that may overheat and damage the motor. • Temperature around the motor should not exceed 140° F (60° C) or be less than -40° F (-40 0 C). • Wear safety glasses to inspect the equipment while it is running or while working on the equipment, especially if cover plates are removed. NOTICE • 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 FLEXPSC61 ECM Condenser Fan Motor is properly packaged for shipment and storage and should be kept in a clean and dry indoor area. • Read all instructions thoroughly and be familiar with the equipment before installing or working on it. • To prevent damage to HVAC system, verify temperature rise is within the original equipment specifications of the manufacturer in all modes of operation. • Ball bearing motors are permanently lubricated. No maintenance is required. • Do not strike the motor shaft with a hammer or other tool as this may damage the bearings.

FINAL CHECKS • Make sure motor is mounted tightly in condensing unit. • Check lead connections, inspecting for shorts and detached wiring. Make sure all wiring connections are securely connected. • Check motor and verify fan rotation. Make sure it spins freely manually without effort or assisted means in both directions. Verify set screw on fan blade has been properly tightened. • Check that the circuit breaker is ON. -
Page 10: Troubleshooting
Troubleshooting Symptom Corrective Action • Verify thermostat is issuing call for activity. • Check circuit breaker for trips or accidental shutoff. Motor is not spinning • Verify that motor is properly connected. • Inspect for shorts or detached wiring. • Inspect motor and fan for accumulated dirt or other signs of damage. • Inspect fan for bent or missing blades, misaligned shaft, or unsecured mounting to shaft. Motor rattles or makes excessive noise • Inspect motor mounting for cracks, dents, or corrosion. • Inspect motor mounting to verify it is properly secured. • Verify that motor shaft spins freely without effort, by hand, in both directions. CWLE rotation: Check to make sure you have 24V across Blue and Orange leads. Motor spinning in the wrong direction CCWLE rotation: Orange and Blue leads should have no voltage. Power must be off in order for rotation to change. Blue lead not connected for 24V Common when 875 rpm is required. Motor rotating at the wrong Yellow lead should have 24V for 875 rpm. Yellow lead should have no voltage for 1075 rpm. -
