• High efficiency.

• Compact design.

• Wider range of horizontal discharge air.

• Air Filter with function to reduce dust and smoke.

• Long installation piping up to 15 meter (CS/CU-V12DKE),

10 meter (CS/CU-V7DKE & CS/CU-V9DKE).

• Supersonic Air Purifying System with Super Alleru-Buster.

− Inactive various harmful airbone elements including

allergens, viruses and bacteria.

− Generated supersonic waves enhance the ability to

collect dust and dirt in the air.

• Quality Improvement

− Random auto restart after power failure for safety restart

operation.

− Gas leakage detection.

− Prevent Compressor reverse cycle.

− OLP to protect Compressor.

− Noise prevention during soft dry operation.

− Blue coated Condenser for high resistance to corrosion.

− Anti-dew formation control (Cooling & Soft Dry).

• Operation Improvement

− Quiet mode to provide quiet operation.

− Powerful mode to reach the desired room temperature

quickly.

− Ionizer control for generating negative ion in discharge

air.

− 24-hour timer setting.

• Serviceability Improvement

− Removable and washable Front Panel.

• Environmental Friendly

− R410A, which does not contain chlorine, is used as its

refrigerant, so there is no danger of damage to the

ozone layer in Stratosphere.

2.3. Outdoor Unit

•To protect compressor from reverse

rotation when there is a instantaneous

power failure.

60 Secs. Forced Operation Control

•Once the compressor is activated, it

does not stop within the first 60 secs.

However, it stops immediately with

remote control stop signal.

Overload Protector

•OLP to protect the compressor. Overload

Protector will trip when

–Temperature of compressor increases

to 120°C.

–High temperature or high current flows
