Procedure 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 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) 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 3048mm 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 3048mm 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.
10) On a flat surface that does not collect rain water.
11) Away from strong wind.
12) Away from direct exposure to rain or snow.
13) Away from sea breeze.
14) Away from inflammable materials.
15) Away from high temperature or open flames.
Note:
1) Cannot be installed hanging from ceiling or stacked.
2) If installing on a high place such as a roof, with a fence or guard rail around it.
3) If there is a potential for accumulated snow to block the air inlet or heat exchanger, install the unit on a higher
base.
4) R32 refrigerant is an unsafe, nontoxic and flammable refrigerant. However, if there is a concern about a
dangerous level of refrigerant concentration in the case of refrigerant leakage, add extra ventilation.
5) Avoid installing the outdoor unit where corrosive gases, such as sulfur oxides, ammonia, and sulfurous gas, are
produced. If unavoidable, consult with an installation specialist about using a corrosion-proof or anti-rust additive to
protect the unit coils.
6) For seacoast applications, block the unit from direct exposure to sea breeze by installing the unit behind a
structure (such as a building) or a protective wall that is 1.5 times higher than the unit, leaving 700 mm of space
between the wall and unit for air circulation. Consult an installation expert about taking anti-corrosion measures,
such as removing salinity on the heat exchanger and applying a rust inhibitor more frequently than once a year.
