TABLE 3 - ELECTRICAL DATA
1
Maximum fuse or maximum circuit breaker (HACR type per NEC).
2
Based on three 75°C insulated copper conductors in conduit and ambient of 30°C.
3
Based on 5% voltage drop, since unit controls are powered off the unit supply. Two minute time delay between system 1 and system 2.

FIG. 3 - TYPICAL FIELD WIRING
1
Only required when an electric heat
accessory is used.
*All outdoor units and all heat pump only indoor units
require dual element, time delay fuses. Circuit
breakers can be used in lieu of fuses for indoor units
with an electric heat accessory.
