1. Features

(1) Normal body

). 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

---Thinner body than the former, 298mm height is easier for installation and saving space.

*. A wild variety of optional accessories

---Including front clapboard, panel, canvas air passage, filter, etc.

Canvas air passage Clapboard

Panel

+. A long-life and high-efficiency filter

,. 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.
