Gree VRF Copper Branch Joint Manifold Kit

Winland's branch joints are made of pure copper and designed base on the technical dimensions of original drawing and try to enhance the cost performance. Download Branch Joint Catalog

Base on the types of cooling medium, Gree branch joints models could be classified into two types:

R22 Refrigerant: FQ01,FQ02,FQ03,FQ04
R410 refrigerant: FQ01A,FQ01B,FQ02,FQ03,FQ04

Gas/Liquid Pipe of Branch Joint

Branch joint use for VRV/VRF air conditioning systems, it also called dispenser pipes. The branch joint is combined with gas pipe and liquid pipe.

We could tell the gas/liquid pipes easily by appearance: pipe of bigger size is gas pipe, and smaller size is liquid pipe.

Gree Branch Joint Installation

Gree Manifold Pipe Installation Instructions

Install the refrigerant branch kit while observing the following condition and referring to the installation instruction above.

Ensure the manifold is colose to the IDU to reduce impact on refrigerant assignmenet by IDU branches
The manifold match with the devices
Ensure the manifold medel is correct

Manifolds can be laid in the following ways.

Horizontal installation: The three ports must be on the same level. The shaping size and assembly angle cannot be changed
Vertical installation: The direction can be upwards or downwards. Three ports must be on the same elevation without inclination
The length of a straight pipe between two manifolds cannot be less than 500mm
The length of a straight pipe before the main pipe port of the manifold cannot be less than 500mm
The length of a straight pipe between the branch of the manifold and the IDU cannot be less than 500mm
