Y-type manifold pipe is equipped with auxiliary tubes to adjust the diameter of different pipes. If
the dimension of the pipe selected for site use is different from the dimension of manifold pipe joint,
use the pipe cutter to cut from the middle of the pipe with different dimensions, and deburr as well.
Please see below.
Y-type manifold pipe must be installed so that the manifold is in vertical or horizontal direction.

Cut in the middle
On air pipe side, heat preservation materials able to endure 120 or a high temperature
shall be used for heat preservation of manifold pipe. Do not use the foam on manifold pipe as the
material for heat preservation. To prevent liquid pipe from leaking, it is required to connect the two
types of heat
preservation materials end to end, i.e. the foam material on manifold pipe and the heat
preservation
material used on site. After that, wrap up the joints between the two types of materials.
Caution!
For multi-split air conditioner system, each pipe shall be pasted with label to identify the pipe for
each system and avoid wrong connection.
4.7 Installation of Protective Layer on Connection Pipe
1). To avoid condensate dew or water leakage on connecting pipe, the air pipe and liquid pipe
must be wrapped with heat preservation material and adhesive pipe for insulation from the
air.
2). The joints on indoor unit and outdoor unit must be wrapped with heat preservation materials
and have no clearance against the wall surface of indoor unit and outdoor unit.
No Clearance
