MODEL DESIGNATION
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.

TIPS FOR SAVING ENERGY
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:
• Do not cool excessively indoors. This may be harmful for 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 tightly 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.
