3.6. Indoor unit installation
• Use the included and
fasten the indoor unit
at 4 locations (→)
each at top and the
middle of the unit.
• When the unit is set
to the wall, use the
wall hook bracket
and hook the top of
the indoor unit on the
indoor unit wall hook
bracket.
• Install it so that there
is no gap between
the indoor unit and
the wall.

Fix the indoor unit with 4 screws surely. If improperly installed, might cause to injury due
to the toppling or falling.
Install the indoor unit at the place that has adequate strength. Install the indoor unit so
that the installed unit can withstand the weight of adult body weight.
If improperly installed, might cause accidental injury due to the toppling or falling.
3.7. Installing the wall hook bracket
(1) Install the wall hook bracket so that it is correctly positioned horizontally and verti-
cally. If the wall hook bracket is tilted, water will drip to the floor.
(2) Install the wall hook bracket so that it is strong enough to support the weight of the
unit.
• Fasten the wall hook bracket to the wall with 5 or more screws through the holes near
the outer edge of the bracket.
• Check that there is no rattle at the wall hook bracket.

Install the wall hook bracket level, both horizontally and vertically.
4. PIPE INSTALLATION
Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant R410A models. Also, when storing the piping, securely seal the openings by
pinching, taping, etc.
While welding the pipes, be sure to blow dry nitrogen gas through them.
4.1. Selecting the pipe material
Do not use existing pipes from another refrigeration system or refrigerant.
Use pipes that have clean external and internal sides without any contamination which
may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or water.
It is necessary to use seamless copper pipes.
Material : Phosphor deoxidized seamless copper pipes
It is desirable that the amount of residual oil is less than 40 mg/10 m.
Do not use copper pipes that have a collapsed, deformed, or discolored portion (es-
pecially on the interior surface). Otherwise, the expansion valve or capillary tube may
become blocked with contaminants.
Improper pipe selection will degrade performance. As an air conditioner using R410A
incurs pressure higher than when using conventional (R22) refrigerant, it is necessary to
choose adequate materials.
• Thicknesses of copper pipes used with R410A are as shown in the table.
• Never use copper pipes thinner than those indicated in the table even if they are avail-
able on the market.
