Failure to observe a warning may result in death.
Failure to observe a caution may result in injury or damage to
the equipment.
After completing the installation, make sure that the unit operates
properly during the start-up operation. Please instruct the customer
on how to operate the unit and keep it maintained. Also, inform cus-
tomers that they should store this installation manual along with the

WARNING
CAUTION
WARNING
Install according to these installation instructions strictly.
If installation is defective, it will cause water leakage, electrical shock
and fire.
When installing the unit in a small room, take measures against to
keep refrigerant concentration from exceeding allowable safety
limits in the event of refrigerant leakage.
Contact your installer for more information. Excessive refrigerant in a
closed ambient can lead to oxygen deficiency.
Use the attached accessories parts and specified parts for instal-
lation.
Failure to do so could lead to the system failing, water leakage, electri-
cal shock and fire.
Unit should only be mounted on a suitable load bearing ceiling and
surface.
Not enough or installation is not properly done, the set will drop to
cause injury.
The appliance shall not be installed in the laundry room.
Before obtaining access to terminals, all supply circuits must be
disconnected.
The appliance must be positioned so that the plug is accessible.
The enclosure of the appliance shall be marked by word, or by
symbols, with the direction of the fluid flow.
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 in electrical work, it
will cause electrical shock fire.
Use only 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.
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.
If the supply cable is damaged, it must be replaced by the manu-
facture or its service agent or a similarly qualified person in order
to avoid a hazard.
An all-pole disconnection switch having a contact separation of at
least 3 mm in all poles should be connected in fixed wiring.
When carrying out piping connection, take care not to let air
substances go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in
the refrigeration cycle, explosion and injury.
Do not modify the length of the power supply cable or use of
extension cable, and do not share the single outlet with other
electrical appliances.
Otherwise, it will cause fire or electrical shock.
Carry out the specified installation work after taking into account
strong winds.
Improper installation work may result in the equipment falling and
causing accidents
