Drilling a wall hole and installing wall embedded pipe
WARNING
For metal frame or metal board walls, be sure to use a wall embedded pipe and wall hole cover in the feed-through hole to
prevent possible heat, electric shock, or fire.
• Be sure to caulk the gaps around the pipes with caulking material to
prevent condensation.
1) Drill a feed-through hole with a
φ
2-9/16 inch (65mm) (for 09/12 class),
φ
3-1/8 inch (80mm) (for 15 class) diameter through the wall at a
downward angle toward the outside.
2) Insert a wall embedded pipe into the hole.
3) Insert a wall hole cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk the
pipe hole gap with putty.
Inside
Outside
Even if a wall hole cover is
not used, caulk both the
outdoor and indoor sides
with putty.

Installing the indoor unit
In the case of bending or curing refrigerant pipes, keep the following precautions in mind.
Abnormal sound may be generated if improper work is conducted.
• Do not strongly press the refrigerant pipes onto the bottom frame.
• Do not strongly press the refrigerant pipes on the front grille, either.
3-1� Right-side, right-back, or right-bottom piping
1) Attach the drain hose to the underside of the refrigerant pipes with
adhesive vinyl tape.
2) Wrap the refrigerant pipes and drain hose together with
J
insulation
tape.

3) Pass the drain hose and refrigerant pipes through the wall hole, then
position the indoor unit on the

4) Open the front panel (Refer to “
Installation Tips”on page 10), then open
the service lid (Refer to “
Indoor Unit Installation Diagram”on page 4).
5) Pass the inter-unit wire from the outdoor unit through the feed-through
wall hole and pass to the front of indoor unit from the back. Then pull
them at front side. Bend the ends of cable tie wires upward for easier
work in advance. (If the interunit wire ends are to be stripped first, bundle
wire ends with adhesive tape.)
6)
Press the bottom frame of the indoor unit with both hands until it is firmly
caught by the
A
mounting plate hooks. Make sure the wire leads do not
catch on the edge of the indoor unit.
