NOTE:
Insert the field pipe firmly until it touches the joint pipe (Branch kit).
CAUTION
Use a pipe cutter to cut a pipe. Point the pipe downward while deburring so that cutting
chips will not enter inside the pipe.
(3) The installation direction for the branch kit is shown as follows.

CAUTION
If it is placed horizontally, keep it within ± 5°.
Otherwise, it will not separate the refrigerant
evenly, causing a reduction in performance.

• During piping work, apply nitrogen gas while brazing the pipes. If pipes are brazed
without applying nitrogen gas, it will create a large amount of oxidation film, which will
cause a critical malfunction.
• To prevent moisture or foreign matter from entering during work, do not leave the
piping open.
• Refer to the Installation Manual supplied with the outdoor unit for airtightness test and
evacuation procedures.
About the connecting curvature of field pipe and branch kit:
The field pipe should be connected to the branch kit so that the curved angle on each
side is 3 degree or less.
* 0 to 26 mm
(0 to 1 in.)
* 0 to 26 mm
(0 to 1 in.)
0.5 m (19-11/16 in.)
*: Allowed value based on “A” (center of field pipe) at 0.5 m (19-11/16 in.) from “B”
(junction of the branch kit).
4. After brazing the pipes, use the supplied insula-
tion to insulate them.
(1) Remove the protective sheet from the double-stick tape that is affixed to the heat
insulation.
Double-stick tapes
(2) Be sure to install the tape (Accessory) in each heat insulation to the 2 positions as
shown in the following figure.
Tapes (accessories)
(3) Use tape (locally purchased) to seal the seam so that there will be no gap at the
junction between the aforementioned heat insulation and the heat insulation on the
local piping.

Insulations
(locally purchased)
CAUTION
Insulate the liquid and gas pipe completely. If not, it may cause the water condensation
or performance reduction.
Wrap the heat insulation with tape or pipe cover in order to extend the life time of heat insulation.
(a) Environment temperature ≥ 35°C (95°F) and humidity 85%.
(b) Environment temperature ≥ 25°C (77°F) and humidity 90%.

管道作业期间,进行管子铜焊时要使用氮气。如果进行
管道铜焊时不使用氮气,将产生大量氧化膜,从而导致
严重故障。
为了防止在作业期间进入水分或异物,请勿使管道处于
打开状态。
有关气密试验和抽真空的步骤,请参见室外机附带的安
装说明书。
关于现场管道和分流部件的连接曲率:
现场管道应连接到分流部件,使得每侧的弯曲角度为 3
