When installing a multi-zone system (multiple indoor units with a single outdoor unit), ensure that the length
of the refrigerant pipe and the drop height between the indoor and outdoor units meet the requirements in the
table above and illustrated in Fig. 4.3 below:

NOTE: The length of refrigerant piping will
affect the performance and energy
efficiency of the unit. Nominal efficiency
is tested on units with a pipe length of
16.5 ft (5 m). The standard pipe length in
North America is 25 ft (7.5 m). The
refrigerant piping should be a minimum
9.84 ft (3 m) to minimize excessive noise
& vibration.
