2.4.1. Windy location installation
When installing the outdoor unit on a rooftop or other location unprotected from
the wind, situate the air outlet of the unit so that it is not directly exposed to strong
winds. Strong wind entering the air outlet may impede the normal airflow and a
malfunction may result.
The following shows three examples of precautions against strong winds.
1
Face the air outlet towards the nearest available wall about 50 cm away from the
wall. (Fig. 2-3)
2
Install an optional air guide if the unit is installed in a location where strong winds
from a typhoon, etc. may directly enter the air outlet. (Fig. 2-4)

3
Position the unit so that the air outlet blows perpendicularly to the seasonal wind
direction, if possible. (Fig. 2-5)

Stacked unit arrangement (Fig. 2-18)
•
The units can be stacked up to two units high.
•
No more than two stacked units must be installed side by side. In addition, leave space as
shown.
3. Installing the outdoor unit
•
Be sure to install the unit in a sturdy, level surface to prevent rattling noises dur-
ing peration. (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 of the bottom
surface of the base.
•
Secure the base of the unit
fi
rmly with four-M10 foundation bolts in sturdy loca-
tions.
Installing the outdoor unit
•
Do not block the vent. If the vent is blocked, operation will be hindered and
breakdown may result.
•
In addition to the unit base, use the installation holes on the back of the unit to
attach wires, etc., if necessary to install the unit. Use self-tapping screws (ø5 ×
15 mm or less) and install on site.
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 mini-
mize the risk of damage from earthquakes, typhoons, or strong winds. An
incorrectly installed unit may fall down and cause damage or injuries.
