Installation Notices
1) Select the branch pipes' model according to the Model Selection Guide and the downstream indoor unit capacity.
2) According to the actual piping size and cut off the needless parts with special tools such as cutter, take the EVRI-
BP1 gas0 side for example and the operating steps as follow:
a.When selecting model EVRI-BP1 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 EVRI-BP6 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.

Installation Precaution

1) Pay attention to the distance of straight horizontal pipe.
>0.5m
>0.5m
Indoor unit
a.The straight horizontal pipe's distance between two adjacent branch
pipes should ≥0.5m.
b.Distance between two adjacent branches should ≥0.5m.
c.The straight horizontal pipe's distance which outdoor unit connecting
behind the branch pipe should ≥0.5m.
