Precautions for Selecting the Location

1)  Choose a place solid enough to bear the weight and vibration of the unit, where the operation sounds will not be amplified.
2)  Choose a location where the hot air discharged from the unit or the operation sounds will not disturb the neighbors of the user.
3)  Avoid installing near bedrooms so that operation sounds will not be a problem.
4)  There must be sufficient spaces for carrying 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 be free from the possibility of flammable gas leakage in a nearby place.
7)  Install units, power cords and inter-unit wire at least 10ft (3m) away from television and radio sets. This is to prevent interference 

to images and sounds. (Noises may be heard even if they are more than 10ft (3m) away depending on radio wave conditions.)

8)  In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the air conditioner.
9)  Since drain flows out of the outdoor unit, do not place anything under the unit which must be kept away from moisture. 

NOTE

Cannot be installed hanging from 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 snowfall areas, select an installation site where the snow 

will not affect the unit.

Construct a large canopy.
Construct a pedestal.

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

Precautions on Installation

• Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise after installed.
• In accordance with the foundation drawing, fix the unit securely by means of the foundation bolts.  

(Prepare 4 sets of 1/2 inch (M12) foundation bolts, nuts and washers each which are available on the market.)

• It is best to screw in the foundation bolts until their ends are 3/4 inch (20mm) from the foundation surface.

3/4 inch 

(20mm)
