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.

4
 EN

•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.
•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.
•Keep any required ventilation openings clear of obstruction.
•Means for disconnection must be incorporated in the fixed wiring
in accordance with the wiring rules.
•Do not install the unit in potentially explosive atmospheres.

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.

5
 EN

•Cut off the power supply if there is any noise, smell, or smoke
coming from the air conditioner.
•Do not leave flammable substances such as gasoline, benzene, or
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.
•Be sure to ventilate sufficiently when the air conditioner and a
heating appliance such as a heater are used simultaneously.
•Do not block the inlet or outlet of air flow.
•Do not insert hands or other objects through the air inlet or outlet
while the air conditioner is operating.
•Make sure that the power cable is neither dirty, loose, nor broken.
•Never touch, operate, or repair the air conditioner with wet hands.
•Do not place any objects on the power cable.
•Do not place a heater or other heating appliances near the power
cable.
•Do not modify or extend the power cable. Scratches or peeling
insulation on the power cables may result in fire or electric shock,
and should be replaced.
•Cut off the power supply immediately in the event of a blackout or
a thunderstorm.

6
 EN

•Take care to ensure that power cable could not be pulled out or
damaged during operation.
•Do not touch refrigerant pipe, water pipe and any internal parts
while the unit is operating or immediately after operation.

Maintenance
•Do not clean the appliance by spraying water directly onto the
product.
•Before cleaning or performing maintenance, disconnect the power
supply and wait until the fan stops.

Technical Safety
•Installation or repairs made by unauthorized persons can pose
hazards to you and others.
•Any person who is involved with working on or breaking into a
refrigerant circuit should hold a current valid certificate from an
industry-accredited assessment authority, which authorizes their
competence to handle refrigerants safely in accordance with an
industry recognized assessment specification.
•Servicing shall only be performed as recommended by the
equipment manufacturer. Maintenance and repair requiring the
assistance of other skilled personnel shall be carried out under the
supervision of the person competent in the use of flammable
refrigerants.
•The information contained in the manual is intended for use by a
qualified service technician who is familiar with the safety
procedures and equipped with the proper tools and test
instruments.
•Failure to read and follow all instructions in this manual can result
in equipment malfunction, property damage, personal injury and/or
death.

7
 EN

•The appliance shall be installed in accordance with national wiring

regulations.
•When the power cord is to be replaced, the replacement work
shall be performed by authorized personnel using only genuine
replacement parts.
•This appliance must be properly grounded to minimize risk of
electric shock.
•Do not cut or remove the grounding prong from the power plug.
•Attaching the earth wire to the power outlet cover screw does not
ground the appliance unless the cover screw is metal, uninsulated,
and the power outlet is grounded through house wiring.
•If you have any doubt whether the air conditioner is properly
grounded, have the power outlet and circuit checked by a qualified
electrician.
•The refrigerant and insulation blowing gas used in the appliance
require special disposal procedures. Consult a service agent or a
similarly qualified person before disposing of them.
•If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified person in
order to avoid a hazard.
•The appliance shall be stored in a well-ventilated area where the
room size corresponds to the room area as specified for
