Cautions Regarding Products after Repair
Warning
Be sure to use parts listed in the service parts list of the applicable model and appropriate
tools to conduct repair work. Never attempt to modify the equipment.
The use of inappropriate parts or tools can cause an electrical shock, excessive heat
generation or fire.
When relocating the equipment, make sure that the new installation site has sufficient
strength to withstand the weight of the equipment.
If the installation site does not have sufficient strength and if the installation work is not
conducted securely, the equipment can fall and cause injury.
Be sure to install the product correctly by using the provided standard installation frame.
Incorrect use of the installation frame and improper installation can cause the equipment
to fall, resulting in injury.
For integral
units only
Be sure to install the product securely in the installation frame mounted on a window
frame.
If the unit is not securely mounted, it can fall and cause injury.
For integral
units only
Be sure to use an exclusive power circuit for the equipment, and follow the technical
standards related to the electrical equipment, the internal wiring regulations and the
instruction manual for installation when conducting electrical work.
Insufficient power circuit capacity and improper electrical work can cause an electrical
shock or fire.
Be sure to use the specified cable to connect between the indoor and outdoor units. Make
the connections securely and route the cable properly so that there is no force pulling the
cable at the connection terminals.
Improper connections can cause excessive heat generation or fire.
When connecting the cable between the indoor and outdoor units, make sure that the
terminal cover does not lift off or dismount because of the cable.
If the cover is not mounted properly, the terminal connection section can cause an
electrical shock, excessive heat generation or fire.
Do not damage or modify the power cable.
Damaged or modified power cable can cause an electrical shock or fire.
Placing heavy items on the power cable, and heating or pulling the power cable can
damage the cable.
Do not mix air or gas other than the specified refrigerant (R-410A) in the refrigerant
system.
If air enters the refrigerating system, an excessively high pressure results, causing
equipment damage and injury.
If the refrigerant gas leaks, be sure to locate the leak and repair it before charging the
refrigerant. After charging refrigerant, make sure that there is no refrigerant leak.
If the leak cannot be located and the repair work must be stopped, be sure to perform
pump-down and close the service valve, to prevent the refrigerant gas from leaking into
the room. The refrigerant gas itself is harmless, but it can generate toxic gases when it
contacts flames, such as fan and other heaters, stoves and ranges.
When replacing the coin battery in the remote controller, be sure to disposed of the old
battery to prevent children from swallowing it.
If a child swallows the coin battery, see a doctor immediately.
