This indoor unit is equipped with the built-in Wi-Fi

interface.
Be sure to use wall hole sleeve (C)
to prevent indoor/outdoor connect-
ing wire (A) from contacting metal
parts in the wall and to prevent
damage by rodents in case the
wall is hollow.
After the leak test, apply insulating material tightly
so that there is no gap.
When the piping is to be attached to a wall containing metals (tin plated) or metal
netting, use a chemically treated wooden piece 20 mm or thicker between the
wall and the piping or wrap of insulation vinyl tape around the piping.
To use existing piping, perform cooling operation for 30 minutes and pump
down before removing the old air conditioner. Remake flare according to the
dimension for new refrigerant.
Cover the connection part with tape to prevent water from leaking.
Warning
To avoid risk of fire, embed or protect the refrigerant piping.
External damage on the refrigerant piping can be cause of fire.
Do not block the inlet of the outdoor unit with the excess part of the pipes.
