Installation of remote control
(Sold separately)
For installation of the wired remote control, follow the
Installation Manual attached with the remote control.
• Pull out the remote control cord together with the
refrigerant pipe or drain pipe.
Pass the remote control cord through upper side of
the refrigerant pipe and drain pipe.
• Do not leave the remote control at a place exposed
to direct sunlight and near a stove.
Wireless remote control
The sensor of indoor unit with wireless remote control
can receive a signal from a distance within approx. 23’
(7 m). Based on this, determine a place where the
remote control can be operated and the installation
place.
• Operate the remote control, confirm that the indoor
unit receives a signal, and then install it.
• Keep it 3.3' (1 m) or more from devices such as
television, stereo etc.
(Disturbance of image or noise may generate.)
• To prevent malfunction, select a place away from
fluorescent light or direct sunlight.
• Two indoor units with wireless type remote control
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 65.6’ (20 m) or less. For a long pipe, provide support brackets
at intervals of 4’11" to 6’7" (1.5 to 2 m) 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.
