4. The smart way to use

Even minimal steps to care for your air conditioner can help make its use far
more effective in terms of air-conditioning effect, electricity charges, etc.
Set the right room temperature
• In cooling operation, a temperature difference of about 5°C between indoors
and outdoors is optimum.
• If the room temperature is raised by 1°C during air-cooling operation, about 10%
electric power can be saved.
• Excessive cooling is bad for health. It also results in the waste of electric power.

Clean the filter thoroughly
• Air filter is not provided within the unit, however correctly sized filter (field sup-
ply) must be installed in the return air.
• If the screen of the air filter becomes clogged, the airflow and air-conditioning
effect can be significantly reduced. Further, if the condition is left unattended,
failure can result. It is particularly important to clean the filter at the beginning
of the cooling and heating seasons. (When profuse dust and dirt have accu-
mulated, clean the filter thoroughly.)
