Precautions for Selecting a Location

1) 

Choose a place solid enough to bear the weight and vibration of the unit, where the operating sound will not be amplified.

2) Choose a location where the air discharged from the unit or the operating sound will not cause a nuisance to the neighbors of 

the user.

3) Avoid locations, such as near bedrooms, where the operating sound may cause disturbance.
4) 

There must be sufficient space to carry the unit into and out of the site.

5) 

There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.

6) 

The site must not be prone to flammable gas leaks in the surrounding area.

7) In coastal areas or other places with a salty atmosphere or one containing sulfate gas, corrosion may shorten the life of the air 

conditioner.

8) 

Since water will flow from the drain of the outdoor unit, do not place anything under the unit which must be kept away from 

moisture.

9) 

A location where flammable gas does not leak. Position at least 6-5/8ft (2m) from propane gas cylinders.

NOTE
Cannot be installed suspended from a ceiling or stacked.

CAUTION

When operating the air conditioner in a low outdoor ambient temperature, be sure to 
follow the instructions described below.
•  To prevent exposure to wind, install the outdoor unit with its suction side facing the 

wall.

•  Never install the outdoor unit at a site where the suction side may be exposed 

directly to wind.

• 

To prevent exposure to wind, it is recommended to install a baffle plate on the air 

discharge side of the outdoor unit.

•  In heavy snow areas, select an installation site where the snow will not affect the unit.
•  If there is a likelihood of snow accumulating on the outdoor unit, attach a snow 

protection hood.

•  In high humidity areas or heavy snow areas, it is recommended to attach a drain pan 

heater to prevent ice build-up from the bottom frame.

• Construct a large canopy.
• Construct a pedestal.

Install the unit high enough off 
the ground to prevent burying 
in snow.
