Step 1 - Preparation

Procedure for Selecting the Location
• Choose a place solid enough to bear
the weight and vibration of the unit and
where the operation noise will not be
amplified.
• Choose a location where the hot air
discharged from the unit or the operation
noise and will not cause a nuisance to the
neighbors of the user.
• There must be sufficient space for
carrying the unit into and out of the site.
• There must be sufficient space for air
passage and no obstructions around the
air inlet and air outlet.
• The site must be free from the possibility
of flammable gas leakage in a nearby
place.
• Locate the unit to avoid noise and
discharged hot air will not annoy the
neighbors.
• Install units, power cords and inter-unit
cables at least 10ft away from television
and radio sets. This is to prevent
interference to images and sounds.
(Noise may be heard even if they are

more than 10ft away depending on radio
wave conditions.)
• Since drain flows out of the outdoor unit,
do not place anything under the unit that
must be kept away from moisture.
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 ex-
changer, install the unit on a higher base.
4) 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.
5) Avoid installing the outdoor unit where
corrosive gases, such as sulfur oxides, am-
monia, 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.
