 Wireless remote controller
(sold separately)
The signal receiving unit of indoor unit can receive a
signal by distance within approx. 7 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.
(Disturbance of image or noise may generate.)
• To prevent a malfunction and reception failure of the
remote controller, select a place where it is not
influenced by a fluorescent light, equipment emitting
(Unit: mm)
infrared rays (Electronic whiteboard etc.), or direct
sunlight.
• Switching the setting (A-B selection) of the wireless
remote controllers and the signal receiving unit
enables two indoor units installed in a room to be
respectively operated using two wireless remote
controllers.

Drain piping

CAUTION 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.
NOTE
• 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.
• For collective piping, the pipes must be equivalent to VP30 and sloping downward at an angle of 1/100 or more.
• If clearance occurs between piping/wiring and drain hose in opening the knockout hole, apply putty to the
clearance.
• If the pipe passes through a fire retarding division, apply incombustible material (putty) to the clearance at
penetration part.
• 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.
 Pipe material, size and insulator
The following materials for piping work and insulating process are procured locally.
Pipe material Hard vinyl chloride pipe, pipe elbow (Nominal outer diameter Dia.20 mm)
Insulator Foamed polyethylene foam, thickness: 10mm or more
Drain pan
Drain hose
Use adhesive for hard polyvinyl chloride pipe
