Install 5" black wire included with kit onto (supplied) as shown in Figure 3. compressor contactor where the black fan motor wire 7. Remove black fan motor wire from compressor was removed, and then connect other end of wire to contactor and place on installed terminal block (see the terminal block opposite the black fan motor wire. Figure 3). NOTE: A generic wiring diagram is provided on page 4.

9. Remove service port cap and screw low 10. Run wires from low ambient fan cycling control up ambient cycling control onto service port (see Figure into control panel with fan motor lead wires. Be sure 4). Finger tighten first, then use a wrench to tighten to work permagum seal back into place after wires an additional 1/4 turn. Use a second wrench to back have been run to control panel. up the service port while tightening the . Apply 11. Connect the low ambient control wires to the soap solution to ensure refrigerant connection is leak- installed terminal block: One wire goes with the free. black fan motor wire and the other goes with the FIGURE 4 installed black wire connected to the compressor contactor (see Figure 4) 12. Remove two (2) screws securing the low voltage terminal strip and gently pull the low voltage terminal strip out (see Figure 5). 13. Disconnect yellow wire from Y1 terminal and pull out of terminal box. 14. Route yellow wire supplied with kit into the low voltage box and connect to Y1 terminal where wire Low Ambient Fan was removed in previous step. Cycling Control 15. Gently push low voltage terminal strip back into place and secure with the two (2) screws removed earlier.

17. Open supplied heat sink compound capsule and apply to face of supplied freeze stat. Clip freeze stat onto lowest feeder tube as close to the coil as possible, then wrap with supplied insulation tape (see Figures 7A and 7B). FIGURE 8 18. Route freeze stat wires down through blower partition with suction and liquid tubes. 19. Route wires down into loom across the front of the blowers. Plug into yellow wires installed there in Step 16 (see Figure 8). 20. Replace all panels and turn power back on 21. Force a cooling call and confirm that the compressor starts and with a delay (waiting until the compressor discharge pressure builds), the outdoor fan motor starts.
