Product information
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.
Airborne Noise Emission
Limiting concentration is the limit of Freon gas
concentration where immediate measures can
be taken without hurting human body when
refrigerant leaks in the air. The limiting
concentration shall be described in the unit of
kg/m3(Freon gas weight per unit air volume)
for facilitating calculation.

Installation
• Do not use a defective or underrated circuit breaker. Use the correctly rated
breaker and fuse. There is risk of fire or electric shock.
• For electrical work, contact the dealer, seller, a qualified electrician, or an
Authorized Service Center. Do not disassemble or repair the product by
yourself. There is risk of fire or electric shock.
• Always ground the product as per the wiring diagram. Do not connect the
ground wire to gas or water pipes lightening rod or telephone ground wire.
There is risk of fire or electric shock.
• 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
installation area does not deteriorate with age. It may cause product to fall.
• 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.
• 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.)
• Keep any required ventilation openings clear of obstruction.
IMPORTANT SAFETY INSTRUCTIONS
• The appliance shall be stored in a well-ventilated area where the room size
corresponds to the room area as specified for operation. (for R32)
• For installation of the product, always contact the service center or a
professional installation agency.
Otherwise, it may cause a fire, electrical shock, explosion or injury.
• Mechanical connections shall be accessible for maintenance purposes.
• The appliance shall be disconnected from its power source during service and
when replacing parts.
• The appliance shall be installed in accordance with national wiring regulations.
Operation
• When the product is soaked (flooded or submerged) in water, contact an
Authorized Service Center for repair before using it again. There is risk of fire or
eletric shock.
• Be sure to use only those parts which are listed in the svc parts list. Never
attempt to modify the equipment. The use of inappropriate parts can cause an
electrical shock, excessive heat generation or fire.
• Do not touch, operate, or repair the product with wet hands. Hold the plug by
hand when taking out. There is risk of electric shock or fire.

electrostatic filter, if the unit is so equipped.) There is risk of physical injury,
electric shock, or product failure.
• If strange sound, smell or smoke comes from product. Immediately turn the
breaker off or disconnect the power supply cable. There is risk of electric shock
or fire.
• Ventilate the product room from time to time when operating it together with a
stove, or heating element etc. Oxygen deficiency can occur and hence harm
your health.
• Do not touch refrigerant pipe and water pipe or any internal parts while the unit
