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. ·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. ·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

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 operation. ·The appliance shall be stored in a room
