Remark:
1.One, two, three or four indoor units can be connected according your need;
2.As 18000 Btu/h unit, just Cassette and duct are available.
3.There should be no more two duct indoor units and other indoor units should be all wall mounted in a system;
4.There should be no more one cassette and other indoor units should be all wall mounted in a system;
5.Cassette and duct can not be combined in a system;
6.When heating, capacity attenuate sharply if indoor unit capacity exceed too much.
