Safety Precautions
When installing and moving the air conditioner to
another site, do not charge it with a different refriger-
ant from the refrigerant specified on the unit.
• If a different refrigerant or air is mixed with the original
refrigerant, the refrigerant cycle may malfunction and the
unit may be damaged.
Ventilate before operating air conditioner when gas
leaked out.
• It may cause explosion, fire, and burn.
If the air conditioner is installed in a small room, measures must be taken to prevent the
refrigerant concentration from exceeding the safety limit when the refrigerant leaks.
• Consult the dealer regarding the appropriate measures to prevent the safety limit from being exceeded. Should the refrig-
erant leak and cause the safety limit to be exceeded, harzards due to lack of oxygen in the room could result.
Don't use the existing manifold gage for R22 refriger-
ant.
• Use the manifold gage for high pressure (R410A) as possible
as for stable refrigerant filling.
Use a vacuum pump or Inert (nitrogen) gas when doing leakage test or air purge.
Do not compress air or Oxygen and Do not use Flammable gases.
Otherwise, it may cause fire or explosion.
• There is the risk of death, injury, fire or explosion.
■ Operation
Do not damage or use an unspecified power cord.
• There is risk of fire, electric shock, explosion, or injury.

equipped.)
• There is risk of physical injury, electric shock, or product failure.
4 Outdoor Unit
Do not reconstruct to change the settings of the pro-
tection devices.
• If the pressure switch, thermal switch, or other protection
device is shorted and operated forcibly, or parts other than
those specified by LGE are used, fire or explosion may result.
Securely install the cover of control box and the panel.
• If the cover and panel are not installed securely, dust or
water may enter the outdoor unit and fire or electric shock
may result.
Don't mix and use the R22 pipe and the installation
appliances that were used until now
• Mixing the oil of R22 and R410A may cause
failure of the unit due to hydrolysis.
Use a dedicated outlet for this appliance.
• There is risk of fire or electrical shock.
Do not touch the power switch with wet hands.
• There is risk of fire, electric shock, explosion, or injury.
When the product is soaked (flooded or
submerged), contact an Authorized Service Center.
• There is risk of fire or electric shock.
Take care to ensure that nobody could step on or fall
onto the outdoor unit.
• This could result in personal injury and product damage.
