IMPORTANT SAFETY INSTRUCTIONS
WARNING
• To reduce the risk of explosion, fire, death, electric shock, injury
or scalding to persons when using this product, follow basic
precautions, including the following:
Children in the Household
• This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible
for their safety. Children should be supervised to ensure that they do
not play with the appliance.
Installation
• Do not install the air conditioner on an unstable surface or in a place
where there is danger of it falling.
• Contact an authorized service center when installing or relocating the
air conditioner.
• Install the panel and the cover of the control box safely.
• Do not install the air conditioner in a place where flammable liquids or
gases such as gasoline, propane, paint thinner, etc., are stored.
• Make sure that the pipe and the power cable connecting the indoor and
outdoor units are not pulled too tight when installing the air conditioner.
• Use standard circuit breaker and fuse that conform to the rating of the
air conditioner.
• Do not input air or gas into the system except with the specific
refrigerant.
• Use non-flammable gas (nitrogen) to check for leak and to purge air;
using compressed air or flammable gas may cause fire or explosion.
SAFETY INSTRUCTIONS
• The indoor/outdoor wiring connections must be secured tightly, and
the cable should be routed properly so that there is no force pulling the
cable from the connection terminals. Improper or loose connections
can cause heat generation or fire.
• Install dedicated electric outlet and circuit breaker before using the air
conditioner.
• Do not connect the ground wire to a gas pipe, a lightning rod, or a
telephone ground wire.
• Means for disconnection must be incorporated in the fixed wiring in
accordance with the wiring rules.
• Keep any required ventilation openings clear of obstruction. (for R32)
Operation
• Be sure to use only those parts listed in the service parts list. Never
attempt to modify the equipment.
• Make sure that children do not climb on or hit the outdoor unit.
• Dispose of the batteries in a place where there is no danger of fire.
• Use only the refrigerant specified on the air conditioner label.

thinner near the air conditioner.
• Contact an authorized service center when the air conditioner is
submerged by flood waters.
• Do not use the air conditioner for an extended period of time in a small
place without proper ventilation.
• In the event of a gas leak (such as Freon, propane gas, LP gas, etc.)
ventilate sufficiently before using the air conditioner again.
• To clean the interior, contact an authorized service center or dealer.
Using harsh detergents may cause corrosion or damage to the unit.
• Be sure to ventilate sufficiently when the air conditioner and a heating
appliance such as a heater are used simultaneously.
