NOTICE
Specifications are subject to change without notice for further improvement.
All the product information has been carefully checked.

Part 1. Product Features
1) Lower noise level
2) Smoother air flow with less turbulence
---Owing to the multiple-blade fan rotor and the air guide design, the airflow is getting smoother and more
comfortable
3) One direction air flow
---Quick cooling
4) Stylish design
---Be harmonious with any interior decoration and creates an elegant environment
5) Ultra thin machine body
---Space saving: only 235mm
6) Convenient installation
---Able to be flexibly installed in various corners
---Standardized sectional module
--- More flexible in routing the tube through the ceiling space due to the condensed water can be lift through
the drain pump up to 750mm above the drain port
7) Easier to do cleaning and maintenance
---Flat type suction grille of easy cleaning

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.
