Technical Service Instruction Sollatek FCA23 Installation Appendix Rewiring the 4-Wire EBM Fan Motor If the evaporator fan motor cycles or is a 4-wire motor, it must be rewired to operate correctly with the new electronic temperature control. See the procedure below. 1. Locate the black EBM wire sleeve containing black, brown, blue, and green/yellow wires. See fig. 1. 2. Cut the black and brown fan motor wires 1" (25.4 mm) from their respective connectors. See fig. 2. 3. With a provided 2-way lever connector, cap the black wire left attached to the original connector. 4. With a provided 2-way lever connector, cap the brown wire left attached to the original connector. 5. Strip 7/16" (11.1 mm) of insulation from the fan motor side of the black and brown wires. 6. With a provided 3-way lever connector, connect the stripped black and brown fan motor wires to the provided bare black wire. 7. Crimp a provided spade connector to the bare black wire. 8. Connect the black wire to the temperature control Aux1 terminal. See fig. 3. Fig. 1. The four fan motor wires and wire sleeve. 845565 Fig. 2. EBM fan motor original black and brown connections.
