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)

Refer to the figures for each case.
1 Obstacles at rear only (Fig. 2-6)
2 Obstacles at rear and above only (Fig. 2-7)
3 Obstacles at rear and sides only (Fig. 2-8)
4 Obstacles at front only (Fig. 2-9)
∗ When using an optional air outlet guide, the clearance for P100-140 models is 500 mm or
more.
5 Obstacles at front and rear only (Fig. 2-10)
∗ When using an optional air outlet guide, the clearance for P100-140 models is 500 mm or
more.
6 Obstacles at rear, sides, and above only (Fig. 2-11)
* Do not install the optional air outlet guides for upward airflow.
2.4.3. When installing multiple outdoor units (Refer to the last page)
Leave a 10 mm space or more between the units.
1 Obstacles at rear only (Fig. 2-12)
2 Obstacles at rear and above only (Fig. 2-13)
* No more than three units must be installed side by side. In addition, leave space as shown.
* Do not install the optional air outlet guides for upward airflow.
3 Obstacles at front only (Fig. 2-14)
∗ When using an optional air outlet guide, the clearance for P100-140 models is 1000 mm or
more.
4 Obstacles at front and rear only (Fig. 2-15)
∗ When using an optional air outlet guide, the clearance for P100-140 models is 1000 mm or
more.
5 Single parallel unit arrangement (Fig. 2-16)
∗ When using an optional air outlet guide installed for upward airflow, the clearance is 500
(1000) mm or more.
6 Multiple parallel unit arrangement (Fig. 2-17)
∗ When using an optional air outlet guide installed for upward airflow, the clearance is 1000
(1500) mm or more.
7 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.
• Be sure to install the unit in a sturdy, level surface to prevent rattling noises during
operation. (Fig. 3-1)

• 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 P125, 140 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.
