16 General Information
Large capacities for large-sized buildings
Piping length is drastically extended! The long piping length provides more design flexibility, which can match
even large-sized buildings.

40 m or less r
1. No special requirements up to 40 m. The maximum actual piping length can be 90 m, or less depending on conditions. Various conditions
and requirements have to be met to allow utilisation of 90 m piping length. Be sure to refer to the Engineering Data for details of these
conditions and requirements.
2. Level differences above 50 m are not supported by default but are available on request for RXQ8PA-54PA. (If the outdoor unit is above the
indoor unit.)
