Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Excessive cooling may be harmful to your health and may consume more electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

• 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.
A 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.
