About ECONOMY Operation
● When ECONOMY operation mode is operated, the room temperature will be little higher than the set-temp under cooling mode
and lower than set-temp under heating mode. Therefore, the ECONOMY mode is able to save more energy than other normal
mode.
● In case of single-type, at the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation
for cooling and heating.
● In case of multi-type air conditioner, the ECONOMY operation mode is only available for the set indoor unit.
● If the room is not cooled (or heated) well during ECONOMY operation, select normal operation.
● During the monitor period in the AUTO mode, the air conditioner operation will not change to ECONOMY operation even if
ECONOMY operation is selected by pressing the ECONOMY operation button.

Cleaning the Air Filter

● Remove the dust from the air fi lters by vacuuming or washing them. After washing, allow the air fi lters to dry thoroughly
in an area protected from sunlight.
● Dust can be cleaned from the air fi lter either with a vacuum cleaner, or by washing the fi lter in a solution of mild deter-
gent and warm water. If you wash the fi lter, be sure to allow it to dry thoroughly in a shady place before reinstalling.
