wall in the piping direction, at the position shown in the diagram to the left.
s The hole should incline so that the outside opening is lower than the inside
opening.

s Since the indoor unit weighs near 30 kg, 66 lbs selection of the mounting
location requires thorough consideration. If the wall does not seem to be
strong enough, reinforce it with boards or beams before installation.
s The mounting fixture must be secured at both ends and at the centre, if
possible. Never fix it at a single spot or in any nonsymetrical way.
(If possible, secure the fixture at all the positions marked with a bold arrow.)

3.3. When embedding pipes into the wall (Fig. 3-5)
• The pipes are on the bottom left.
• When the cooling pipe, drain pipes internal/external connection lines etc are to be
embedded into the wall in advance, the extruding pipes etc, may have to be bent
and have their length modified to suit the unit.
• Use marking on the mount board as a reference when adjusting the length of the
embedded cooling pipe.

4. Installing the refrigerant piping
4.1. Precautions
4.1.1. For devices that use R410A refrigerant
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil
applied to the flared sections.
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specified in the table to the below. Make sure the insides of the pipes are
clean and do not contain any harmful contaminants such as sulfuric com-
pounds, oxidants, debris, or dust.
Warning:
When installing or moving the air conditioner, use only the specified refriger-
ant (R410A) to charge the refrigerant lines. Do not mix it with any other refriger-
ant and do not allow air to remain in the lines. Air enclosed in the lines can
cause pressure peaks resulting in a rupture and other hazards.

4.2. Connecting pipes (Fig. 4-1)
• When commercially available copper pipes are used, wrap liquid and gas pipes
with commercially available insulation materials (heat-resistant to 100 °C, 212 °F or
more, thickness of 12 mm, 1/2 inch or more).
45° 2°
C
• The indoor parts of the drain pipe should be wrapped with polyethylene foam insu-
lation materials (specific gravity of 0.03, thickness of 9 mm, 23/64 inch or more).
• Apply thin layer of refrigerant oil to pipe and joint seating surface before tightening
flare nut.
D
• Use two wrenches to tighten piping connections.
• Use refrigerant piping insulation provided to insulate indoor unit connections. Insu-
late carefully.

5. Drainage piping work
A
B
5.1. Drainage piping work (Fig. 5-1)
• Drain pipes should have an inclination of 1/100 or more.
• For extension of the drain pipe, use a soft hose (inner dia. 15 mm, 19/32 inch)
available on the market or hard vinyl chloride pipe (VP-20/O.D. ø26 mm, 1-1/32
inch PVC TUBE). Make sure that there is no water leakage from the connections.
• If the drain pipe passes indoors it must be covered with insulating material (foamed
polyethylene: specific gravity: 0.03, thickness: 9 mm, 23/64 inch or more) available on the
market.
C
Fig. 5-1
• Do not put the drain piping directly in a drainage ditch where sulphuric gas may be
generated.
• When piping has been completed, check that water flows from the end of the drain
pipe.

Caution:
The drain pipe should be installed according to this Installation Manual to en-
sure correct drainage. Thermal insulation of the drain pipes is necessary to
prevent condensation. If the drain pipes are not properly installed and insu-
lated, condensation may drip on the ceiling, floor or other possessions.

7.1. Before test run
s After completing installation and the wiring and piping of the indoor and outdoor
units, check for refrigerant leakage, looseness in the power supply or control
wiring, wrong polarity, and no disconnection of one phase in the supply.
s Use a 500-volt megohmmeter to check that the resistance between the power
supply terminals and ground is at least 1.0 MΩ.
s Do not carry out this test on the control wiring (low voltage circuit) termi-
nals.
Warning:
Do not use the air conditioner if the insulation resistance is less than 1.0 MΩ.
