6. REFRIGERANT PIPE INSTALLATION
Ventilate the air if there was any refrigerant leakage during
installation.Leaked refrigerant will generate poisonous gas if in
contact with fire.
Make sure there is no refrigerant leakage after installation.
Leaked refrigerant will generate poisonous gas if in contact with
fire.

5.4 Indoor Unit Installation
Pass the piping through the hole in the wall.
Put the claw at the back of the indoor unit on the hook of
the installation board, move the Indoor Unit from side to
side to see that it is securely hooked.
Piping can easily be made by lifting the indoor unit with
a cushioning material between the indoor unit and the
wall. Get it out after finish piping.
Push the lower part of the Indoor Unit up to the wall,Then
move the Indoor Unit from side to side, up and down to
check if it is hooked securely.
Because the condensed water from rear of the indoor unit is
gathered in a condensation container and is piped out of room.
Do not put anything else in this container.
