Accessories supplied with the outdoor unit:

Precautions for Selecting the Location

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 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. 

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

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

ference to images and sounds.  (Noises may be heard even if they are more than 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 under the unit anything 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 tempera-
ture, be sure to follow the instructions described below.

1) To prevent exposure to wind, install the outdoor unit with its suction 

side facing the wall.

2) Never install the outdoor unit at a site where the suction side may 

be exposed directly to wind.

3) To prevent exposure to wind, it is recommended to install a baffle 

plate on the air discharge side of the outdoor unit.

4) In heavy snowfall areas, select an installation site where the snow 

will not affect the unit.
