Precautions for Selecting the Location

 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.
