1. Features

(1) Low operation noise---Streamline plate ensures quietness---Creates natural and comfortable environment

(2) Efficient cooling---Equal, fast and wide—range cooling

(3) The adoption of the most advanced 3-Dimensional Screw Fan---Reduces the air resistance passing through---Smoothes the air flow

---Makes air speed distribution to the heat exchange uniform

(4) Improvement for easy installation and maintenance---Little space is required for installation into a shallow ceiling---Because of the compactness and weight reduction of the main unit and panel, all models can beinstalled without a hoist

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.
