*Typical operating charge with 7.62 m of interconnecting piping. Operating
charge is approximate for maximum system capacity. Unit is factory supplied
with nitrogen holding charge. Refrigerant charge for dual circuit units is the
total for both circuits.
†Maximum vertical separation between evaporator coil and condensing unit if
condensing unit is below the evaporator.
