*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.
