Use a flare tool designed for R410A or a conventional flare tool.

Please note that measurement B (protrusion from the flaring block) will vary depending on the

type of a flare tool in use.

If a coventional flare tool is used, please use a copper pipe gauge or a similar instrument to

check protrusion so that you can keep measurement B to a correct value.

Cover the coupling with insulator and then cover it with tapes.



Cover the indoor unit’s flare-connected joints, after they are checked for a gas leak, with an indoor

unit heat insulating material and then wrap them with a tape with an attached insulation pad placed

over the heat insulating material’s slit area.

Vinyl tape

Use an attached insulation pad for heat insulation.

Position it so that the slit area faces upward.

 Connect the pipes on both liquid and gas sides.

 Tighten the nuts to the following torque.

Liquid side (ø6.35) : 14.0 - 18.0 N·m (1.4 - 1.8 kgf·m)

Gas side (ø9.52) : 34.0 - 42.0 N·m (3.4 - 4.2 kgf·m)

 How to remove the indoor unit from the installation board

 Arrange the drain hose in a downward angle

 Avoid the following drain piping.

 Pour water to the drain pan located under the heat exchanger, and ensure that the water is discharged outdoor.

 When the extended drain hose is indoor, always use a shield pipe (to be arranged by the user) and ensure it is

thermally insulated

Fixing of indoor unit

Since this air conditioner has been designed to collect dew drops on the rear

surface to the drain pan, do not attach the power cord above the gutter.

Drainage

Go through all installation steps and check if the

drainage is all right. Otherwise water leak may occur.
