Installation Notices

1) Select the branch pipes’

2) According to the actual piping size and cut off the needless parts with special tools such as cutter, take the

model according to the Model Selection Guide and the downstream indoor unit capacity.

JOINT IN 01 gas0 side for example and the operating steps as follow:

a.When selecting model JOINT IN 01, the actual object as display in Fig.1, and then suppose that the present

using pipe isΦ15.9 , then as display in Fig.2, cut the welded pipe of the branch pipe component.

b.As display in Fig.2, cut the standalone connecting pipe.

c.As display in Fig.3, weld the branch pipe components with the field pipes.

3) Particularly notice the followings:

a.When the actual pipe size matches with the un-welded side of U-shape three direct links, weld the pipe with the

U-shape three direct links directly.

b.For the separate un-welded connecting pipe of JOINT IN06, as display in Fig. 3, please cut in the bottom of the

necking side if the flaring side is needed to be used, and vice versa.
