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.

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.
