Page 4: Safety Considerations
® Safety Considerations The following safety warning symbol is used throughout this manual as a safety consideration for installation and operation of the Evergreen EM motor. This warning indicates a hazardous situation which, if not avoided, could result in serious injury or death. Please read and observe all of these safety concerns. -
Page 5: Introduction/Applications
® Introduction and Features The ultra-high-efficiency ECM has become the preferred motor for use in energy-saving HVAC systems. Evergreen EM is made with the same field- proven, high-efficiency ECM technology that has been used for more than 20 years in new HVAC equipment. The Evergreen EM was designed to replace direct-drive blower motors in residential and light commercial indoor furnaces, air handlers, and package systems that were designed with a standard ECM motor, such as an X13 or equivalent competitor model. -
Page 6: Mounting
® Mounting Always disconnect the main power from the unit being serviced before disconnecting any wiring or removing any components. It is also a good practice to confirm that the power is off with a meter. Remove the blower section from the HVAC system. Remove the existing ECM motor from the blower section and properly dispose of the motor. - Page 7 ® Mounting (CONT’D) If a new motor mount is required and the legs do not line up with the original holes in the blower housing, it is required to use a bolt with either a lock washer and nut or a locking nut through the drilled hole(s).

Page 8: Electrical Connections
® Electrical Connections The unique design of the Evergreen EM allows for multiple speed operation using either 24VAC (18VDC) discrete inputs or variable speed, torque control using a PWM controller. The high voltage power terminals, (L) and (N), must be connected to a continuous, un-switched power supply. -
Page 9: High Voltage Power Connections
® Electrical Connections High Voltage Power Connections The Evergreen EM is designed for continuous un-switched connection to its rated high voltage power supply. Motor operation is controlled by low voltage signal inputs. Always confirm the rating on the motor matches the power supply of the system it is applied to and/or the motor it is replacing. -
Page 10: Low Voltage Signal Connections
® Electrical Connections Low Voltage Signal Connections (24VAC) Discrete Speed Operation The Evergreen EM has 5 available speeds using 24VAC control inputs. The inputs of the Evergreen can connect directly to the 24VAC thermostat terminal strip or 24VAC signal outputs from the HVAC system control board. DO NOT connect the Low Voltage SIGNAL (speed) terminals to the high voltage power supply. - Page 11 ® Electrical Connections Low Voltage Signal Connections (18VDC) Discrete Speed Operation The Evergreen EM has 3 available speeds using 18VDC control inputs. DO NOT connect the Low Voltage SIGNAL (speed) terminals to the high voltage power supply. Applying voltage above 23VDC to these terminals will cause permanent damage to the motor.
- Page 12 ® Electrical Connections Low Voltage Signal Connections Variable Speed Torque Control Option The Evergreen EM can also be controlled in a variable speed, torque control mode using a PWM (Pulse Width Modulation) control on terminals (C) and (1). The motor will operate from 10% - 100% output depending on the input from the ECM PWM speed controller.

Page 13: Final Notes
® Electrical Connections Final Notes Retrofit ECM PWM controllers are available from manufacturers, some of which are listed on www.theDealerToolbox.com. Any control that meets the specifications listed on the previous page should operate the Evergreen EM properly. If there are questions regarding a particular add-on control or building automation system, please call Evergreen technical support at 866-503-8566. -
Page 14: Sequence Of Operation
® Sequence of Operation Nameplate-rated line voltage is connected to the High Voltage POWER terminals of the motor at all times. This voltage powers the micro- processor and the controls that drive the motor; however, the motor will only operate when there is a demand on the Low Voltage SIGNAL terminals. 24VAC operation –... -
Page 15: Maintenance
® Maintenance The Evergreen EM motor is permanently lubricated and requires no maintenance. Any signs of water damage on the replaced motor, in the HVAC system, or on the Evergreen EM should be taken very seriously. Fix the water issues immediately. -
Page 16: Troubleshooting Guidelines
® Troubleshooting Guidelines The High Voltage Power terminals (L) and (N) must be connected to nameplate rated voltage at all times. The acceptable High Voltage input range is 90-132VAC for 115V models and 180-264VAC for 208-230VAC models. If the motor does not operate, confirm this voltage is present at the motor and make repairs to the HVAC system if it is not. - Page 17 ® Troubleshooting Guidelines (CONT’D) PWM will operate the motor anytime a proper signal is present between terminals (C) and (1). The (C) Common terminal must be connected to the PWM controller. Check the PWM controller specifications for the appropriate DC signal. Check this signal at the motor on terminal (1). The specifications required by the motor are as follows: 15-23VDC at 67-93Hz or 127 to 199Hz 10% Guaranteed On and 5% Guaranteed Off Duty Cycle...
- Page 18 ® Troubleshooting Guidelines (CONT’D) Connect motor terminals 1, 3, & 5 to either 24VAC or 18VDC and Common to terminal C. Reconnect the main power to the HVAC system. Energize motor terminals 1, 3, & 5 with either 24VAC or 18VDC and Common to terminal C continuously for a minimum of 5 minutes.
