1. Features
1. New design, more modern and elegant appearance.
2. Convenient installation
--The ceiling type can be easily installed into a corner of the ceiling even if the ceiling is very narrow
--It is especially useful when installation of an air conditioner in the center of the ceiling is impossible due to
a structure such as one lighting.
3. Two direction auto swing (vertical & horizontal) and wide angle air flow,
--Air flow directional control minimizes the air resistance and produces wilder air flow to vertical direction.
--The range of horizontal air discharge is widened which secures wider air flow distribution to provide more
comfortable air circulation no matter where the unit is set up
4. Three level fan speed, more humanism design, meets different air-supply requirement.
5. Water proof by utilizing the absorbing plastic film on water collector
6. Easy operation. Auto-restart function, remote control and optional wire control method.
7. Low noise level plus compact size
--Shape of the blades has been improved to prevent noise caused by turbulence.

Notes:
1. Nominal cooling capacities are based on the following conditions:
Indoor temp: 27°CDB, 19°CWB; Outdoor temp: 35°CDB; Equivalent ref. Piping: 7.5m(horizontal)
2. Nominal heating capacities are based on the following conditions:
Indoor temp: 20°CDB; Outdoor temp: 7°CDB, 6°CWB; Equivalent ref. Piping: 7.5m(horizontal)
3. Actual noise level may differ, depending on the room structure, etc, since these noise values are from an
anechoic room.
