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