4) Install at a strong and firm location which is able to withstand the set s weight. If the strength is not enough
or installation is not properly done, the set will drop and cause injury.

,

5) For electrical work, follow the local national wiring standard, regulation and this installation instructions. An
independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defect found
in electrical work, it will cause electrical shock fire.

6) Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on
the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.

7) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover
is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock.

8) When carrying out piping connection, take care not to let air substances other than the specified
refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure
in the refrigeration cycle, explosion and injury.

prevent direct sunlight or rain exposure,
make sure that heat radiation from the
condenser is not restricted.
Ensure that the clearance around the back
of the unit is more than 30cm and left side is
more than 30cm. The front of the unit should
have more than 200cm of clearance and the
connection side (right side) should have more
than 60cm of clearance.
Do not place animals and plants in the path of the air inlet or outlet.
Take the air conditioner weight into account and select a place where noise and vibration
will not be an issue.
Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.

If the outdoor unit is installed on a roof structure, be sure to level the unit.
Ensure the roof structure and anchoring method are adequate for the unit location.
