INSTALLATION MANUAL
Please read ‘Safety Precautions’ described in the installation manual of the air conditioner.
• Check the following parts in the package.
• For further information of the piping material and size of the refrigerant pipes, refer to the installation
manual of the air conditioner.

• Condensate may occur on the heat insulation surface according to the atmosphere inside of the ceiling.
• If the inside of the ceiling has high temperature or humidity rate is more than 80%, please add proper
insulation to prevent water drops.
• The stopper area of the pipe or socket should be spread with a welding material. EX)

Connecting Method
Installing the Y-joint
Insulating the branch joint
Y-joint & liquid side of the outdoor unit
Attach the insulation provided with a branch joint to the insulation supplied in the eld
without a gap. Wrap the connected part with an insulation (Field supply) of a thickness of at
least 10mm.
Use an insulation with the heat resisting temperature over 120°C.
Wrap the branch joint with an insulation of a thickness of at least 10mm.
When insulating in high humidity(higher than 30°C, 80%), wrap the supplied insulation with
more than 10mm of extra insulation such as Polyethylene Foam or other similar material.
Attach the adhesive insulation tape to the pipe
as shown in the picture after insulating the pipe.

Connect the header joint in order respecting the number of the indoor unit.
Connet the indoor unit as the highest capacity comes first.
Install the Y-joint ‘horizontally’ or ‘vertically’.
<Install vertically>
<Using reducer>
- Use connection part of Y-joint or provided
reducer by cutting them in accordance with
diameter of connecting pipe.
- Make certain 10~15mm or more for reducer
which connected with pipe.
- Remove burr on cut part of reducer.
It is impossible to connect reducer with pipe,
if pipe is deformed or reducer is untrimmed.
