4.4 Dimension of Connecting Pipe
4.4.1 The tting pipe (main pipe) from outdoor unit to the 1st manifold has the same dimension as
the tting pipe on outdoor unit.

Note: If the equivalent length of total t pipe exceeds 90m, the tting pipe on gas side and liquid side shall
be increased of one dimension.
4.4.2 Dimension of the tting pipes (manifold pipe) between manifolds is selected according to
the capacity of the connected downstream indoor unit. The capacity of outdoor unit shall prevail if
exceeded.

4.4.3 The tting pipe (indoor tting pipe) from manifold to indoor unit has the same dimension
as the indoor unit tting pipe. (If the distance from the 1st manifold to an indoor unit exceeds
30m, the tting pipe on gas side and liquid side from the 1st manifold to this indoor unit shall be
increased of one dimension).

Note: When the capacity of indoor unit less than 5KW, if the distance from the nearest manifold to the
indoor unit exceeds 10m, the tting pipe on liquid side of the pipe shall be increased of one dimension.
