(*1): Ratio of connected total indoor unit capability to outdoor unit capability
(*2): Maximum indoor connection capacity is varied depending on the height difference between indoor unit H2,
H4, H5.
Combination of indoor units
Standard indoor unit + M-HWM + H-HWM
Standard indoor unit + M-HWM
(*3): HWM connecting capacity should be smaller than standard indoor unit.
(*4): As for 44HP to 54HP of SHRM-e, contact our agent.
(*5): When M-HWM and standard indoor units are not operated simultaneously, it is possible up to 40 m.
(*6): When system capacity is greater than 28HP, height difference between indoor units is limited to 3 m. If the
height difference between indoor units exceeds 3 m with a capacity greater than 28HP there may be a case
of capacity shortage in cooling.
NOTE
Design the system that total capacity of simultaneous heating operation is 100% or less. If total capacity of
simultaneous heating is over 100%, then each indoor units or HWM performance is descended.
