connect to outdoor directly.
1) When connected with 8 units,indoor units refer to <admissible combination examples>
2) Total length=l1+l2*2+l3*4+l4*4+l5*4<=100m
3) Max. piping length =(l1+l2+l3+l5)<=70m
4) Max. piping length between the indoor unit and the first branch pipe<=30m
5) Max. drop between outdoor unit and indoor unit: H<=30m(indoor above
outdoor);H<=20m(indoor below outdoor)
6) Max. drop between the two indoor units : h<=10m
7) Expansion valve is less than 15m to its corresponding indoor unit
8) Only wall mounted types are connected with expansion valves.
9) The expansion valves of different indoor models are different.
10)The first branch pipe must use FQG-180,the others use less than it.

Note:
1.AU28 can connect with max. 5 indoor units, and AU52 can connect with max. 8 indoor units, but pay
attention that the total indoor capacity can not exceed 130% of outdoor cooling capacity.
2.
The ceiling concealed unit must connect with the outdoor unit through the MP2A or MP3A; the wall mounted
unit must connect with the outdoor unit through the exterior EEV box, and EEV only can be installed on the
liquid pipe. While for the cassette unit, because it has the built-in EEV, so it need not anything and it can
