* Permissible limits of voltage range at which unit will operate satisfactorily.
{ Unit ampacity = 125 percent of largest operating component's full load amps plus 100 percent of all other potential operating components' (EAC,
humidifier, etc.) full load amps.
} Length shown is as measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop.
** Time ---delay type is recommended.
WARNING
!
ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning coud result in electrical
shock, fire, or death.
The cabinet MUST have an uninterrupted or unbroken
ground according to NEC ANSI/NFPA 70- -2002 and
Canadian Electrical Code CSA C22.1 or local codes to
minimize personal injury if an electrical fault should

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.
