Preparing for Installation

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.

– At least 9.84 ft (3 m) away from equipment that generates electromagnetic waves.

– Away from interfering sources, such as radio, computer, and stereo equipment.

– Far enough away from people living and working nearby so that hot discharge air or noise

do not disturb them.

– Away from inflammable materials.

• Ensure that condensate water generated by the outdoor unit can drain smoothly away from the

unit.

• Install the power and communication cables in a separately installed enclosure.

• If installing on a high place such as a roof, with a fence or guard rail around it.

• If there is a potential for accumulated snow to block the air inlet or heat exchanger, install the

unit on a higher base.

• R-410A refrigerant is a safe, nontoxic and nonflammable refrigerant. However, if there is a

concern about a dangerous level of refrigerant concentration in the case of refrigerant leakage,

add extra ventilation.

• 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.

Moving the Mini Outdoor Unit

Follow these guidelines when moving the mini outdoor unit:

• Before moving the unit, determine a path that can support its weight.

• Do not lay the unit on its side and do not slant the unit more than 30 degrees.

• Take care to avoid injury while moving the unit; the surface of the heat exchanger is sharp.

– If moving the unit with a crane, fasten the wire rope as shown in Figure 4. To protect damage

or scratches to the unit, use a spreader bar.

– If the unit is being moved a short distance by hand, two people should lift and carry it

together using the transportation handles on the side of the unit, as shown in Figure 4.
