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
airfl ow and a malfunction may result.
The following shows 3 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) [for BP170-BP250 models : 100cm]
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)

•
Do not install the optional air outlet guides for upward airfl ow.
2.4.3. When installing multiple outdoor units (Refer to the last page)
Leave 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 3 units must be installed side by side. In addition, leave space as
shown.
•
Do not install the optional air outlet guides for upward airfl ow.
3
Obstacles at front only (Fig. 2-14)
• When using an optional air outlet guide, the clearance for BP125-BP250 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 BP125-BP250 models is
1000 mm or more.
• When using an optional air outlet guide installed for upward airfl ow, 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 airfl ow, the clearance is
1000 (1500) mm or more.
7
Stacked unit arrangement (Fig. 2-18)
•
The units can be stacked up to 2 units high.
•
No more than 2 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 operation. (Fig. 3-1)
<Foundation specifi 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 4-M10 foundation bolts in sturdy locations.
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 it fi xes top panel 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.
