Installation Manual
1. PRECAUTIONS
The safety precautions listed here are divided into two categories.
After completing the installation, make sure that the unit operates
properly during the start-up operation. Instruct the customer on
how to operate and maintain the unit. Also, inform the
customer that he or she should store this manual with the user's
manual for future reference.
Only trained and qualified service personnel should
install, repair, or service the equipment.
Improper installation, repair, or maintenance may result in
electrical shock, short-circuiting, leaks, fire, or other
damage to the equipment.

Install the unit strictly according to these installation
instructions.
If installation is done incorrectly, water leakage, electrical
shock, or fire may result.
To prevent refrigerant leakage when installing the unit in a
small room, do not allow refrigerant concentration to
exceed allowable safety limits.
Contact the place of purchase for more information.
Excessive refrigerant in a closed ambient can lead to oxygen
deficiency.
Use the attached accessories parts and specified parts
for installation.
If the wrong parts are used, set failure, water leakage, electrical
shock, or fire may result.
Install the unit at a strong, firm location that can
withstand the unit's weight.
If there is not enough support or the unit is not installed
properly, the unit may fall and cause injuries.
The appliance must not be installed in a laundry room.
Before obtaining access to terminals, disconnect all
supply circuits.
The appliance must be positioned so that the plug is
accessible.
The enclosure of the appliance must be marked, by word or
symbols, with the direction of the fluid flow.
For electrical work, follow the local national wiring
standard, regulations, and these installation instructions.
An independent circuit and single outlet must be used.
If the capacity of the electrical circuit is not large
enough or the electrical work is defective, electrical shock or
fire may result.
Use the specified cable, connect it tightly, and clamp the
cable so that no external force will affect the terminal.
If the connection or fixing is not perfect, overheating or fire will
occur at the connection.
Wiring routing must be properly arranged so that the
control board cover is fixed properly.
If the control board cover is not fixed perfectly,
overheating, electrical shock, or fire will occur at the
connection point of the terminal.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent, or a similarly qualified
person to avoid a hazard.
In fixed wiring, an all-pole disconnection switch
with a contact separation of at least 3 mm in all
poles should be connected.
When connecting pipes, do not let air substances enter the
refrigeration cycle.
Otherwise, lower capacity, abnormal high pressure in the
refrigeration cycle, explosion, or injury may result.
Do not modify the length of the power supply cord or use an
extension cord, and do not share the single outlet with other
electrical appliances.
Otherwise, electrical shock or fire may result.
Carry out the specified installation work after taking into
account strong winds, typhoons, or earthquakes.
Improper installation work may cause the equipment to fall,
causing accidents.
