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.

Outdoor unit

Above 0.5m

Outdoor unit

Above 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.

5 Pipe diameter of outdoor unit :

V4+:8～10HP, Gas/Liquid side:Φ25.4/Φ12.7;12～16HP, Gas/Liquid side:Φ31.8/Φ15.9;

V4、D3:8～12HP, Gas/Liquid side:Φ25.4/Φ12.7;14～16HP, Gas/Liquid side:Φ31.8/Φ15.9.

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 isΦ31.8, main pipe isΦ38.1. 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 sizeΦ31.8 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.

Thank you very much for purchasing our air conditioner, Before using your air conditioner , please read this manual carefully and keep it for future reference.
