If any of the original wire, as supplied, must be replaced, use the same or equivalent type wire.4. Replace low voltage fuse with no greater than 5 amp fuse.5. Use 60 amp class K fuses only, for replacement.6. (3) speed motor shown. Optional (2) speed motor uses HI (BLK) and LOW (BLU or RED).7. Connect R to R, G to G, etc., see outdoor instruction for details.8. If wire crimp is removed an emergency heat relay is required. (See outdoor-thermostat instructions).
