6. Refrigerant Piping Installation
6.1 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.
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.
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.)
