Use copper wire (75°C min.) only between disconnect switch and unit.
To be wired in accordance with N.E.C. and local codes.
If any of the original wire, as supplied, must be replaced, use the same or equivalent type wire.
Replace low voltage fuse with no greater than 5 amp fuse.
Use 60 amp class K fuses only, for replacement.
(3) speed motor shown. Optional (2) speed motor uses HI (BLK) and LOW (BLU or RED).
Connect R to R, G to G, etc., see outdoor instruction for details.
If wire crimp is removed an emergency heat relay is required. (See outdoor-thermostat instructions).

Use copper wire (75°C min) only between disconnect switch and unit.
To be wired in accordance with N.E.C. and local codes.
If any of the original wire, as supplied, must be replaced, use the same or equivalent type wire.
Replace low voltage fuse with no greater than 5 amp fuse.
Use 60 amp class K fuses only, for replacement.
(3) speed motor shown. optional (2) speed motor uses HI (BLK) and LOW (BLU or RED).
Connect R to R, G to G, etc., see outdoor instruction for details.
If wire crimp is removed an emergency heat relay is required. (see outdoor-thermostat instructions)
