NOTICE

Specifications are subject to change without notice for further improvement.

All the product information has been carefully checked.

Part 1. Product Features

1) Low operation noise

---Streamline plate ensures quietness

---Creates natural and comfortable environment

2) Efficient cooling

---Equal, fast and wide—range cooling

Four-way airflow

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

3- Dimensional Screw fan

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 be installed

without a hoist

Notes: 1. Nominal cooling capacities are based on the following conditions:

Indoor temp: 27°CDB, 19°CWB; Outdoor temp: 35°CDB; Equivalent ref. Piping: 8m(horizontal)

2. Nominal heating capacities are based on the following conditions:

Indoor temp: 20°CDB; Outdoor temp: 7°CDB, 6°CWB; Equivalent ref. Piping: 8m(horizontal)

3. Actual noise level may differ, depending on the room structure, etc, since these noise values are from an

anechoic room.
