INSTALLATION OF THE UNIT 

Installation guidelines 

Precautions for selecting the location 

 

MAKE SURE TO PROVIDE FOR ADEQUATE MEASURES IN ORDER TO PREVENT THAT THE OUTDOOR 
UNIT WILL BE USED AS A SHELTER FOR SMALL ANIMALS. 
SMALL ANIMALS MAKING CONTACT WITH ELECTRICAL PARTS CAN CAUSE MALFUNCTIONS, SMOKE 
OR FIRE. PLEASE KEEP THE AREA AROUND THE UNIT CLEAN. 

 

1.

 

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

2.

 

Choose a location where the hot air discharged from the unit or the operation noise will not cause a 
nuisance to the neighbors of the user. 

3.

 

Avoid places near a bedroom and the like, so that the operation noise will cause no trouble. 

4.

 

There must be sufficient space 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.

 

Locate the unit so that the noise and the discharged hot air will not annoy the neighbors. 

7.

 

The site must be free from the possibility of flammable gas leakage in a nearby place. 

8.

 

Install units, power cords and inter-unit cables at least 3m away from television and radio sets. This 
is to prevent interference to images and sounds. 

9.

 

Depending on radio wave conditions, electromagnetic interference can still occur even if installed 
more that 3m away. 

10.

 

In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life 
of the outdoor unit. 

11.

 

Since drain flows out of the outdoor unit, do not place anything under the unit which must be kept 
away from moisture. 

 

Selecting a location in cold climates 

 

WHEN OPERATING THE OUTDOOR UNIT 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, install a baffle plate on the air discharge side of the outdoor unit.   

 

In heavy snowfall areas it is very important to select an installation site where the snow will not 
affect the unit. If lateral snowfall is possible, make sure that the heat exchanger coil is not 
affected by the snow (if necessary construct a lateral canopy).
