How to set the drain plug.
No gap.
Insert a hexagonal wrench (3/16 inch (4mm)).
Do not apply lubricating oil
(refrigerant oil) to the drain
plug when inserting it.
The application of
lubrication oil to the drain
plug will deteriorate the
plug to cause drain
leakage from the plug.

path marking on the
A
mounting plate.
4) Pass the drain hose and refrigerant pipes
through the wall hole, then position the indoor
unit on the
A
mounting plate hooks, using the
markings at the top of the indoor unit as a
