1. Features
1.1 Two-way installation
The rounded design of the ceiling and floor type air conditioner allows either ceiling or floor-level
installation. Ceiling installation saves room space, while floor installation helps prevent the loss of warm
air.
1.2 Brief design
Brief design that is suitable for any interior will not only give you cooling and heating performance but
also upgrade your lifestyle.
1.3 3D airflow
Vertical air flow and horizontal airflow can be adjusted by remote controller, the cooperation of the two
airflow ways help to spread air comfortably throughout even a large room. With these functions, the
whole room can be evenly air-conditioned for both floor-level and ceiling installation.

Quick Cooling To maintain room temp
Air outlet from top and bottom to make quick cooling ------When the A/C is just switched on, or room
temp. is still high, cold air will be blown out from top and bottom air outlet to cool down the room quickly
Air outlet from top to maintain room temp. ----When the room has been cooled down, or the A/C has
been opened over 1 hour, cold air only from the top outlet to keep constant room temp
Heating mode
Anti-cold air ------When the AC is just turn on, temperature of evaporator is very low, in this case, in
order to prevent cold air direct blowing, only the upper louver is opened in a high position, the lower
louver closed.
