Product information
- Product Name : Air conditioner
- Model Name :
Airborne Noise Emission
The A-weighted sound pressure emitted by
this product is below 70 dB.
** The noise level can vary depending on the
site.
The figures quoted are emission level and are
not necessarily safe working levels.
Whilst there is a correlation between the
emission and exposure levels, this cannot be
used reliably to determine whether or not
further precautions are required.
Factor that influence the actual level of
exposure of the workforce include the
characteristics of the work room and the other
sources of noise, i.e. the number of
equipment and other adjacent processes and
the length of time for which an operator
exposed to the noise. Also, the permissible
exposure level can vary from country to
country.
This information, however, will enable the
user of the equipment to make a better
evaluation of the hazard and risk.
- Additional Information : serial number is
refer to the barcode on the product.
- Max allowable pressure High side :
4.2 MPa / Low side : 2.4 MPa
- Refrigerant : R32

ENGLISH
• Install the panel and the cover of control box securely. There is risk of fire
or electric shock due to dust, water etc.
• Use the correctly rated breaker or fuse. There is risk of fire or electric
shock.
• Do not modify or extend the power cable. If the power cable or cord has
scrathes or skin peeled off or deteriorated then it must be replaced. There
is risk of fire or electric shock.
• For installation, removal or reinstall, always contact the dealer or an Authorized Service Center. There is risk of fire, electric shock, explosion, or injury.
• Do not install the product on a defective installation stand. Be sure that the

• Never install the outdoor unit on a moving base or a place from where it
can fall down. The falling outdoor unit can cause damage or injury or even
death of a person.
• In outdoor unit the step-up capacitor supplies high voltage electricity to the
electrical components. Be sure to discharge the capacitor completely before conducting the repair work.
An charged capacitor can cause electrical shock.
• When installing the unit, use the installation kit provided with the product.
Otherwise the unit may fall and cause severe injury.
• 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.
• Safely dispose off the packing materials. Like screws, nails, batteries, broken things etc after installation or svc and then tear away and throw away
the plastic packaging bags. Children may play with them and cause injury.
• Be sure to check the refrigerant to be used. Please read the label on the
product. Incorrect refrigerant used can prevent the normal operation of the
unit.
• Do not turn on the breaker or power under condition that front panel, cabinet, top cover, control box cover are removed or opened. Otherwise, it may
cause fire, electric shock, explosion or death.
• 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.
• The appliance shall be stored in a room without continuously operating ignition sources (for example: open flames, an operating gas appliance or an
operating electric heater)
• Do not use means to accelerate the defrosting process or to clean, other
than those recommended by the manufacturer.
IMPORTANT SAFETY INSTRUCTIONS

ENGLISH
Operation
• Do not use the product for special purposes, such as preserving foods,
works of art, etc. It is a consumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of property.
• Do not block the inlet or outlet of air flow. It may cause product failure.
• Use a soft cloth to clean. Do not use harsh detergents, solvents or splashing water etc. There is risk of fire, electric shock, or damage to the plastic
parts of the product.
• Do not touch the metal parts of the product when removing the air filter.
There is risk of personal injury.
• Do not step on or put anyting on the product. (outdoor units) There is risk
of personal injury and failure of product.
• Always insert the filter securely after cleaning. Clean the filter every two
weeks or more often if necessary. A dirty filter reduces the efficiency.
• Do not insert hands or other objects through the air inlet or outlet while the
product is operating. There are sharp and moving parts that could cause
personal injury.
• Be cautious when unpacking and installing the product. Sharp edges could
cause injury.
• If the refrigerant gas leaks during the repair, do not touch the leakaing refrigerant gas. The refrigernat gas can cause frostbite (cold burn).
• Do not tilt the unit when removing or uninstalling it. The condensed water
inside can spill.
• Do not mix air or gas other than the specified refrigerant used in the system. If air enters the refrigerant system, an excessively high pressure results, causing equipment damage or injury.
• If the refrigerant gas leaks during the installation, ventilate the area immediately. Otherwise it can be harmfull for your health.
• Dismantling the unit, treatment of the refrigerant oil and eventual parts
should be done in accordance with local and national standards.
• Replace the all batteries in the remote control with new ones of the same
type. Do not mix old and new batteries or different types of batteries.
There is risk of fire or product failure.
• Do not recharge or disassemble the batteries. Do not dispose off batteries
in a fire. They may burn or explode.
• If the liquid from the batteries gets onto your skin or clothes, wash it well
with clean water. Do not use the remote if the batteries have leaked. The
chemicals in batteries could cause burns or other health hazards.
• If you swallow the battery fluid from a leak, wash out the inside of your
mouth thoroughly and then consult a doctor. Failure to do so may result in
serious health complications.
IMPORTANT SAFETY INSTRUCTIONS
