Part1. Product features
1. Economic and convenient installation
---Several diffusers branch off from an indoor unit, adjusting the room temperature, which makes many rooms to
be air conditioned with only one indoor unit
---All models feature thin design making them applicable to ceiling pocket that tends to be shallow
2) Awild variety of optional accessories
---Including front clapboard, panel, canvas air passage, filter, etc.
Canvas air passage Clapboard
Panel
3) Along-life and high-efficiency filter
Filter
4) Way of air intake and inserting air filter
---Air intake can be positioned either at the back or below the unit. Similarly, the air filter also can be inserted
either from the back or from the bottom of the unit.

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