WARNING
•
Provide a sufficiently strong foundation. If
not, the unit may fall down and it may lead
to injuries.
•
Do not install the outdoor unit where
the flammable gases may occur or leak.
Otherwise, it may cause a fire.
•
If the indoor unit is installed in a small room
and the refrigerant gas leakage occurs, the
leaked refrigerant gas fills the room and it
may cause suffocation. Do not exceed the
maximum permissible concentration of the
refrigerant gas in the room. Consult with
distributor for countermeasure such as
ventilation system, etc.
3.1 Installation Location
1. Install the outdoor unit in a well dried, ventilated
environment.
2. Install the outdoor unit where it is in the shade
or it will not be exposed to direct sunshine or
direct radiation from high temperature heat
source.
3. Install the outdoor unit where the sound or the
discharge air from the outdoor unit does not
affect neighbors or surrounding ventilation. The
operating sound at the rear or right/left sides is
3 to 6dB(A) higher than the sound at the front
side indicated in the technical catalog.
4. Install the outdoor unit in a space with limited
access to general public.
5. Check to ensure that the foundation is flat, level
and sufficiently strong.
(Perform the foundation work in order to fix
firmly the outdoor unit to avoid inclining,
abnormal sound or falling down due to a strong
wind or earthquake.)
6. Do not install the outdoor unit where dust or
other contaminations could block the outdoor
heat exchanger.
7. Provide adequate drainage around the
foundation. If installing the unit on a roof or a
balcony, provide the additional drainage around
the foundation to prevent water dripping on a
person or forming ice in winter.
8. Do not install the outdoor unit where a seasonal
wind directly blows to the outdoor heat
exchanger or where strong winds through the
tall buildings directly blows to the outdoor fan.

NOTES:
•
Do not install the outdoor unit where there is a
high level of oil mist, flammable gases, salty air
or harmful gases such as sulfur and an acid or
alkaline environment.
•
Do not install the outdoor unit where the
electromagnetic wave is radiated directly to
the electrical box.
•
Install the outdoor unit as far from the
electromagnetic wave radiator as possible, at
least 3 meters away from it.

Wind
Snow attaches directly
to the heat exchanger.
3.2 Service Space and Installation Area
Make the service space when outdoor unit is
installed as follows.
If the service spaces for air inlet and outlet
are insufficient, it may cause a performance
degradation and some abnormalities due to
insufficient air intake.
Additionally, the service space is required for
facilitating the maintenance.
