REFRIGERANT PIPING INSTALLATION

ENGLISH

Precautions on Pipe connection / Valve operation

Pipe connection is done by connecting from the end of the pipe to the branching pipes, and the
refrigerant pipe coming out of the outdoor unit is divided at the end to connect to each indoor
unit. Flare connection for the indoor unit, and welding connection for the outdoor pipe and the
branching parts.

- Use hexagonal wrench to open/close the valve.

Liquid pipe

Gas pipe

CAUTION

Please block the pipe knock outs of the front and side panels after installing the pipes.
(Animals or foreign objects may be brought in to damage wires.)

!

WARNING

• Always careful not to leak the refrigerant during welding.

• The refrigerant generates poisonous gas harmful to human body if combusted.

• Do not perform welding in a closed space.

• Be sure to close the cap of the service port to prevent gas leakage after the work.
