Three-dimensional control over air direction swing is possi-
ble through dual use of both an UP/DOWN air direction swing
and RIGHT/LEFT air direction swing. Since UP/DOWN air
direction flaps operate automatically according to the oper-
ating mode of the unit, it is possible to set air direction based
on the operating mode.

FEATURES AND FUNCTIONS

REMOVABLE INTAKE GRILLE

The indoor unit’s INTAKE GRILLE can be removed for easy
cleaning and maintenance.

thus allowing cleaner use and easier care.

SUPER QUIET OPERATION

When the FAN CONTROL button is used to select QUIET,
the unit begins super-quiet operation; the indoor unit’s air-
flow is reduced for quieter operation.

AIR CLEANING FILTER

The air cleaning filter (Model UTR-FB09-2) and Deodorant

clean the air of fine particulate matter such as tobacco smoke
and plant pollen.
