3. Installation procedure
• Be sure to install the unit in a solid, level surface to prevent rattling noises during
operation. (Fig. 3-1)
<Foundation speci
fi
cations>
Foundation bolt
M10 (3/8")
Thickness of concrete
120 mm
Length of bolt
70 mm
Weight-bearing capacity
320 kg
• Make sure that the length of the foundation bolt is within 30 mm from the surface
of the base.
• Secure the base of the unit
fi
rmly with 4 M10 foundation bolts in solid locations.
Installing the outdoor unit
• Do not block the vent. If the vent is blocked, operation will be hindered and the
unit may breakdown.
• If the additional
fi
xation of the unit is necessary, use the installation holes on the
back of the unit to attach wires, etc. with self-tapping screws (ø5 × 15 mm or
less).
Warning:
• The unit must be securely installed on a structure that can sustain its
weight. If the unit is mounted on an unstable structure, it may fall down and
cause damage or injuries.
• The unit must be installed according to the instructions in order to minimize
the risk of damage by earthquakes, typhoons, or strong winds. An improp-
erly installed unit may fall down and cause damage or injuries.

2.3. Windy location installation
When installing the outdoor unit on a rooftop or other location where the unit is
exposed to strong wind, do not face the air outlet of the unit directly into the winds.
Strong wind entering the air outlet may impede the normal air
fl
ow and it may result
in a malfunction.
The following shows three examples of precautions against strong winds.
1
Face the air outlet towards the nearest available wall keeping about 50 cm dis-
tance. (Fig. 2-2)
2
Install an optional air guide if the unit is installed in a location where strong winds
such as a typhoon, etc. may directly blow to the air outlet. (Fig. 2-3)

Position the unit so that the outlet air can blow at right angle to the seasonal
wind direction, if possible. (Fig. 2-4)
