Please select and install the branch pipe according to outdoor unit installation manual and actual installation conditions.

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.

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 FQZHW-02N1D gas side for example and the operating steps as follow: a.When selecting model FQZHW-02N1D, 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.
