Design & Installation

System configuration suitable for design & installation.

More Flexible Refrigerant Piping Work
  • Max. piping length: 165m
  • Between first branch & indoor unit: 90m or less
  • Height difference between highest & lowest indoor units: 15m or less
  • Height difference between outdoor & indoor units: 50m
  • Max. length after branch: 40m 1. For 100m or more, the pipe diameter will be one size larger. 2. In case the outdoor unit is installed at a higher level than indoor units. If the outdoor unit is installed lower than indoor units, the maximum height difference is 40m.

Layered Installation for High-rise Building

The use of exhaust duct allows layered installation of outdoor units. Outdoor fan motor can provide a higher external static pressure & a long distance air supply, which prevents air return from short-cut in an effective way, then ensures sound ventilation & heat transfer.

vConnectable to 64 Indoor Units Max

The number of connectable indoor units has been increased to 64 maximums. Thus, the system can be used in buildings where there are many indoor units to be connected.

Various Model Types Easily Match Different Spatial Layout

Wide capacity range of outdoor units enables free model combination relating to the actual condition of building. There are 70 models in 9 types of indoor units for selection. Planner can choose appropriate type & capacity of indoor units according to interior decoration & functions.

Single Split Air Condition System

Extensive range and full indoor/ outdoor compatibility

The Multizone range was the worlds first all DC inverter Multisplit system with zone by zone cooling or heating for up to four rooms. DC scroll and DC twin-rotary compressor, together with award wining DC inverter RAM technology, aid the achievement of a system power factor of almost 100%, thus providing unparalleled performance and efficiency. The all DC inverter ensures extremely sensitive and accurate temperature control through fuzzy logic and offers remarkably low sound levels. The wide range of units have been designed for cooling operation under low temperatures, down to -10°C. This feature enables cooling to be obtained even in winter on buildings with high internal heat gains due to lighting, people and machines, particularly in areas such as shops and lecture rooms. The heating operation under low temperature, down to -15°C can also be performed.

Main Key Benefits:


  • DC Inverter PAM control
  • Wide selection of indoor unit types and capacities
  • Compatibility between product ranges of outdoor and indoor units
  • Highest COP and low noise.
  • Cooling available under -10°C ambient temperature
  • Heating available under -15°C ambient temperatur
  • Auto restart by previous mode and Auto changeover
  • Washable carbon and anti-bacteria air purifying filter
  • 24hr remote control timer
  • R410a refrigerant
