The pipe section before the twinning pipe must
have at least 500 mm (19-11/16 in) of straight
section.
・
The outdoor unit twinning kit on the low-pressure side must be placed in the outdoor unit that has the larger
capacity index of the two, regardless of the relative positions of the outdoor units or their addresses. (If outdoor
units that have the same capacity are used in combination, the twinning kit can be placed in either outdoor unit.)
If the twinning kit is placed in the outdoor unit that has the smaller capacity, refrigerant will not be properly
distributed and compressor failure may result.

PURY-P200YLM-A, PURY-P250YLM-A, PURY-EP200YLM-A and PURY-EP250YLM-A can be used in a
Hybrid City Multi system. Contact your dealer when connecting the larger capacity units in a Hybrid City Multi
system.
