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 outlet guide and 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)

3. Installing the outdoor unit
(mm)
• Be sure to install the unit in a sturdy, level surface to prevent rattling noises during
operation. (Fig. 3-1)
<Foundation specifications>
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 firmly with four-M10 foundation bolts in sturdy locations.
The figures in parentheses are for P5, 6 models.
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 from earthquakes, typhoons, or strong winds. An incor-
rectly installed unit may fall down and cause damage or injuries.
