1-3. MOUNTING POSITION
OUTDOOR UNIT
For the air conditioner to operate satisfactorily, install it as outlined in the installation manual.
z
Outdoor unit mounting position
● A position that satisfies the mounting space requirements described in “chapter 3.3 Installation space".
● A position where the unit can be installed level.
● A position with enough space for performing pipe work, service and maintenance.
● A position that satisfies the pipe limitations for height and length between the outdoor units to be connected.
z
Outdoor unit mounting limitation
● A position that is not exposed to strong or seasonal winds.
● A position where the blown air does not accumulate.
● A position where there are no obstructions to the air near to the inlet and outlet.
● A position not exposed to radiation from other heat sources.
● A position where the discharge air will not affect animals or plants.
● A position where the noise and hot air will not disturb the neighbor.
● A position with strong installation fixings, which can sufficiently bear the product weight.
● A position that does not transmit noise or vibration.
● A position where drain water discharge is not a problem.
● A position where snow does not accumulate.
● A position not easily affected by electrical noise.
● A position out of reach of children.
● A position where there is no danger of the generation, influx or accumulation of flammable gas.
● A position that does not have a special environment such as large amounts of oil, vapor or sulfide gas.
z
Precaution for outdoor unit mounting position
● Mount the outdoor unit in a position where its tilt is 3 degrees or less.
● When mounting units on each floor or multiple units, secure enough outlet space to prevent a short circuit effect.
● In cold or snowy regions, make sure that the mount is high enough and install a snow protection hood.
● Drain water is discharged from the outdoor unit during operation, so make sure that this drain water is possible to
flow.
● Use material such as vibration-resistant rubber to prevent the transmission of vibration to the floor.
● Securely fix the unit when it may be in a position exposed to strong winds.
● When cooling operation will be conducted at outdoor air temperature below 23°F (-5°C), the outdoor unit must be
installed in a position that is higher than or equal to those of indoor units.
Make sure to mount the outdoor unit 1
(master) closest to indoor unit side.

Installation example
*Do not use a four-corner support foundation.

OK OK
● Do not install directly on the ground, this may result in equipment failure.
● Provide ample space for ice buildup from condensate between the bottom of the unit and the flat surface
on which it is mounted. Otherwise, there is risk that the drainage water will freeze between the device and
thesurface, disabling drainage.
Base
CAUTION
If the unit is installed in a region that is exposed to high winds, freezing conditions, freezing
rain, snow fall or heavy snow accumulation, take appropriate measures to protect it from those
elements.
To ensure stable operation, the outdoor unit must be installed on a raised stand or rack, at or above
the anticipated snow depth for the region.
The installation of snow hoods and drift prevention fencing is recommended when blowing and
drifting snow is common to the region.
