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 28 in. (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.
