ECM blower accessory Part No. 58SSB900131 is used on 2-ton cooling 58SSB060 furnace and Part No. 58SSB900141 is used on3-toncooling58SSB080 furnace. Each ECM blower kit comes completely assembled with an ECM blower motor and controller, and interface circuit board. See Table 1 for a list of parts in assembly shown in Fig. 1. ECM blower kit is used in conjunction with following variable speed outdoor units: 38EV024320 38EV036320 38QV024320 38QV036320 This ECM blower is controlled by outdoor unit and provides variable airflow across furnace coil in response to variable demand on heat pump or air conditioner. For emergency heat, interface circuit board allows furnace control board to operate ECM blower at a fixed rate of speed. This speed is normally adjusted to midpoint of rating plate temperature rise range. Interface circuit board also powers a Parker indoor thermostat, Part No. HH05ZA001. Installation of indoor coil expansion valve, and startup and adjustment instructions are covered in Installation, Start-Up and Service Instructions for the 38EV,QV outdoor units. See detailed system operation and control in the 38EV,QV system operation and troubleshooting guide. A WARNING Turn off power at main disconnect switch before starting installation to avoid possibility of electrical shock.

Slide ECM blower assembly into furnace and tighten screws to secure blower assembly to the blower shelf. 8. Reinstall furnace control box on bottom side of blower shelf. 9. Connect electrical leads from furnace control previously used as blower speed selector taps to numbered connector which is panel mounted on the left side of the interface control box. Black lead to position 1, red lead to position 2, white lead to position C. 10. Double-check to make sure main power disconnect is off. In steps 11 through 14, the 115-v power leads to ECM blower kit connects in parallel with furnace 115-v power supply. To do this: 11. Remove cover of auxiliary junction box. 12. Remove strain relief securing the power leads in place on the auxiliary J-box. 13. Route power leads from ECM blower kit through opening in back of auxiliary junction box. Disconnect black lead from furnace control at door switch, and connect black lead with 3/16-in. piggyback quick-connect from ECM blower kit in its place. Then reconnect black lead from furnace control to 3/16-in. male quick-connect provided on piggyback connector. Remove wire connecting white lead of furnace control to line voltage common line. Connect white wire from ECM blower kit and reinstall wire nut. Make sure all power leads are secured in place using the strain relief provided with this kit. Reinstall cover to auxiliary junction box. Disconnect all existing thermostat leads from the furnace control board if applicable. Connect W, R, and C from terminal block TB3 labeled, HEAT, on interface circuit board located on front of blower housing to their respective thermostat connections on furnace control board, labeled (W, R, C) using field-supplied thermostat wi...
