REQUIREMENT
In case of installing the indoor unit to the floor and the
wall other than wooden floor and wall, the six anchor
bolts (M8 × L50 or longer) are required.
Procure them at the local site.
Direction of vertical louver
The direction of the auto turn louver (Vertical louver)
may change during transportation. As shown below, lift
up the vertical louver lightly, turn it matching with the
direction of the plastic coupling rod, insert it into
clearance of the extrusion, and then arrange the
direction of the vertical louver to the desired direction.
Turn the vertical louver
while lifting up lightly,
and then insert it into the
Vertical louver
clearance of extrusion of
the coupling rod.

controller (Sold separately)
42 to 92
For installation of the wired remote controller, follow the
52 to 102
Installation Manual attached with the remote controller.
• Pull out the remote controller cord together with the
refrigerant pipe or drain pipe.
Pass the remote controller cord through upper side
of the refrigerant pipe and drain pipe.
• Do not leave the remote controller at a place
exposed to the direct sunlight and near a stove.
Wireless remote controller
The sensor of indoor unit with wireless remote
controller can receive a signal by distance within
approx. 8 m. Based upon it, determine a place where
the remote controller is operated and the installation
place.
• Operate the remote controller, confirm that the
indoor unit receives a signal surely, and then install
it.
• Keep 1 m or more from the devices such as
television, stereo.
(Disturbance of image or noise may generate.)
• To prevent a malfunction, select a place where is not
influenced by a fluorescent light or direct sunlight.
• Two or more (Up to 6 units) indoor units with wireless
type remote controller can be installed in the same
room.

Drain piping
CAUTION
• Following the Installation Manual, perform the drain piping work so that water is properly drained. Apply a
heat insulation so as not to cause a dew condensation.
Inappropriate piping work may result in water leakage in the room and wet furniture.
• After opening the knockout hole, deburr the edge.
Burrs adhered to opening of the knockout hole may causes an injury by touching it.
• Provide the indoor drain piping with proper heat insulation.
• Provide the area where the pipe connects to the indoor unit with proper heat insulation. Improper heat insulation
will cause condensation to form.
• The drain pipe must be sloping downward (at an angle of 1/100 or more), and do not run the pipe up and down
(arched shape) or allow it to form traps. Doing so may cause abnormal sounds.
• Restrict the length of the traversing drain pipe to 20 meters or less. For a long pipe, provide support brackets at
intervals of 1.5 to 2 meters to prevent flapping.
• Install the collective piping as shown in the following figure.
• Do not provide any air vents. Otherwise, the drain water will spout, causing water to leak.
• Do not allow any force to be applied to the connection area with the drain pipe.
