Installation Precaution
1) Pay attention to the distance of straight horizontal pipe.
a.The straight horizontal pipe’s distance between two adjacent branch
pipes should
≥
0.5m.
b.The straight horizontal pipe’s distance which outdoor unit connecting
behind the branch pipe should
≥
0.5m.

NOTE
1 When numbers in brackets represent the equivalent length of all liquid pipes < 90m, means the
selected pipe size value.
2 It’s advised to use the Max. HP unit as the main unit. See above figure W2 outdoor unit (main unit).
3 The above figure is only available for the models such as D3,V4 and V4+ series with R410A refrigerant
when they are paralleled connected.
4 Please select T-style three direct links according to user guide of the external packaging bag; please
dumping the redundant T-style three direct links in the accessories and do not use for other purposes.

1)Select the proper branch model according to table2.
2)According to the actual piping size and cut off the needless parts with special tools such as cutter, take the SYSVRF JOINT OUT 02 HP
gas side for example and the operating steps as follow:
a.When selecting model SYSVRF JOINT OUT 02 HP, the actual object as display in Fig.1, and then suppose that the outlet pipe of
the machine is
Φ
31.8, main pipe is
Φ
38.1. As display in Fig.2, cut the standalone connecting pipe Q1 of the branch pipe component.
b.As display in Fig.2, weld the standalone connecting pipe Q1, Q3 with the U-shape three direct link s Q4; abandon the standalone
connecting pipe Q2 because selected pipe size
Φ
31.8 can directly connect with the un-welded side of U-shape three direct links.
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.
b.For the connecting pipes Q3 and Q7, if they need to be cut, please cut in the bottom of the flaring as display in Fig. 4.
