Liquid / Gas
A , B UNIT
6,35 (1/4) / 9,52 (3/8)
1-4. SELECTING THE INSTALLATION LOCATION
• Where it is not exposed to strong wind.
• Where airflow is good and dustless.
• Where rain or direct sunshine can be avoided as much as possible.
• Where neighbours are not annoyed by operation sound or hot air.
• Where rigid wall or support is available to prevent the increase of op-
eration sound or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit, be sure to secure the unit legs.
• Where it is at least 3 m away from the antenna of TV set or radio. Op-
eration of the air conditioner may interfere with radio or TV reception in
areas where reception is weak. An amplifier may be required for the af-
fected device.
• Install the unit horizontally.
• Please install it in an area not affected by snowfall or blowing snow.
In areas with heavy snow, please install a canopy, a pedestal and/or
some baffle boards.
Note:
It is advisable to make a piping loop near outdoor unit so as to reduce
vibration transmitted from there.

Units should be installed by licensed contractor according to local code requirements.
Optional different-diameter joints (port size of outdoor unit → diameter of connection pipe)
Refer to the installation manual of indoor unit for the diameter of connection pipe of indoor unit.
After the leak test, apply insulat-
ing material tightly so that there is
no gap.
When the piping is to be at-
tached to a wall containing metals
(tin plated) or metal netting, use
a chemically treated wooden
piece 20 mm or thicker between
the wall and the piping or wrap 7
to 8 turns of insulation vinyl tape
around the piping.
To use existing piping, perform
COOL operation for 30 minutes
and pump down before removing
the old air conditioner. Remake
flare according to the dimension
for new refrigerant.

Note:
When operating the air conditioner in low outside temperature, be sure
to follow the instructions described below.
• Never install the outdoor unit in a place where its air inlet/outlet side
may be exposed directly to wind.
• To prevent exposure to wind, install the outdoor unit with its air inlet
side facing the wall.
• To prevent exposure to wind, it is recommended to install a baffle
board on the air outlet side of the outdoor unit.
Avoid the following places for installation where air conditioner trouble
is liable to occur.
• Where flammable gas could leak.
• Where there is much machine oil.
• Salty places such as the seaside.
• Where sulfide gas is generated such as a hot spring.
• Where there is high-frequency or wireless equipment.
• Where there is emission of high levels of VOCs, including phthalate
compounds, formaldehyde, etc., which may cause chemical crack-
ing.
