NOTES:
●
The connectable indoor unit capacity ratio can be calculated as follows:
Connectable Indoor Unit Capacity Ratio = Total Indoor Unit Capacity / Total Outdoor Unit Capacity.
●
For the same system, if the connectable indoor unit capacity ratio is over than 100%, and which all the indoor units operate
simultaneously, the capacity of every indoor unit should be less than its rated capacity.
●
Combination capacity is 50-130%.
●

:When the number of indoor units which are connected to the model of RAS-10~12HNBRMQ1 outdoor unit is over than 10
units,the following restrictions are also required to meet.
(a) The piping system must be divided into two main pipes, the total capacity and the number of the units connected to each
main pipe should be as equal as possible.
(b) The maximum height difference between outdoor and indoor units is 30 meters and the maximum height difference
between indoor units is 10 meters, the longest piping length between the branch pipe to the connected indoor unit is 10m.
(c) The connectable indoor unit capacity ratio should not be more than 105%.
(d) Only 0.8~4.0HP of ducted indoor units can be selected.
