SAMPLE SIZE COMBINATIONS AND PERFORMANCE DATA
1) The DC inverter outdoor unit may work with many different combinations of styles (wall, ceiling, ceiling/floor, concealed, etc.) and sizes of indoor units.
2) In real world, there might be small percentage of applications where all indoor units will be working at peak demand of cooling or heating needs. One room
could be at peak demand, others may not. This way, the outdoor unit doesn't need to work at peak speed/load all the time.
3) Not all pairs of refrigerant valves need to be connected at initial installation. But, there is minimum amount of indoor units shall be connected (refer to the spec.
sheet for details).
If only few of indoor units are installed initially, other indoor units can still be installed in the future whenever ready (need to vacuum and adjust refrigerant
charge accordingly).
4) These outdoor unit can only drive all indoor units for one thermal mode at one time. Shall not run cooling in one indoor unit, and heating in another one. In
case of mode conflict or clash, correct the thermal mode which is different from others, or shut off power and select one thermal mode for all indoor units.

* When the rated total capacity of all the indoor units exceeds the rated capacity of outdoor unit, each indoor unit may not output the rated
capacity and one may differ from other, upon other installation/operation factors, it all units are turned on to run compressor simultaneously.
* Must follow pipe length and refrigerant charge adjustment as instructed in below table:
PIPE ADAPTOR
Whenever the outdoor unit gas valve of size 3/8" is to connect with indoor unit gas pipe of 1/2" or 5/8",
one 3/8" - 1/2" or 3/8" - 5/8" adaptor is to be used in between. This reducer is packed separately and
