• Provide a sufficiently strong foundation. If not, the unit may fall down and it may lead to injuries.
• Do not install the unit where flammable gas may be generated or flow. It may cause a fire.
Select the installation location as follows:
• (A) Minimum Space
• (B) Down Slope Pitch of Drain Pipe: 1/25 to 1/100

• Consider the air distribution from the indoor unit to the space of the room, and select a suitable location so that uniform air
temperature in the room can be obtained.
• Do not place flammable materials in the service space for the indoor unit.
• Install the unit where there is no obstacles which may hamper the suction air and discharged air.
• Do not install the unit near a door or a window where the indoor unit may contact humid outside air. Otherwise, dew
condensation may occur.
• In case temperature and humidity inside the ceiling exceeds 30ºC/RH (Relative Humidity) 80%, apply additional insulation
materials to the external surface of the indoor unit to avoid dew condensation.
• If installing the indoor unit to a high ceiling, the warmed air may stay around the ceiling during heating operation. Thus, the
parallel installing of a circulator is recommended.
• Do not install the indoor unit where the airflow from the air outlet blows directly to the temperature detecting devices such an
alarm device or a control device. It may cause a failure of an alarm device or a control device.
• For simultaneous operation of multiple units (twin, triple and quad combination) , the units must be installed in the same room
and be operated under the same conditions. If the room is partitioned by a wall, furniture or a curtain, etc., it may cause an
operation failure. Take care when rearranging furniture or remodeling the room after installation as well.
