* Permissible limits of the voltage range at which the unit will operate satisfactorily.
† Unit ampacity = 125% of largest operating component's full load amps plus 100% of all other potential operating component's (EAC, humidifier,
etc.) full load amps.
‡ Length shown is as measured 1 way along wire path between unit and service panel for maximum 2% voltage drop.
** Time-delay type is recommended.

NOTES:
1. Connect Y or Y/Y2 terminal as shown for proper cooling operation.
2. Proper polarity must be maintained for 115-v wiring.
3. Use W2 with 2-stage thermostat when zoning.
4. If any of the original wire, as supplied, must be replaced, use
same type or equivalent wire.
5. Some thermostats require a "C" terminal connection as shown.
