[ PRECAUTION ]
Since the unit uses a plastic drain pan, prevent welding
spatter and other foreign substances from the air outlet
during installation.
(2) Adjust the unit to fit between the walls.
(3) Check the unit is horizontally level.
CAUTION
• Make sure the unit is installed level using a level or a
plastic tube filled with water. In using a plastic tube
instead of a level, adjust the top surface of the unit to the
surface of the water at both ends of the plastic tube and
adjust the unit horizontally. (One thing to watch out for in
particular is if the unit is installed so that the slope is not
in the direction of the drain piping, this might cause leak-
ing.)

Refer to the "installation manual of the remote controller"
supplied with remote controller.
■ Wall mounted type/floor standing concealed type
Use the installation mount on the rear of the unit for
installation.
