2. Feature

Clean Design

High Comfort

High Efciency

The outdoor unit takes no screw clean design in the top cover, this design makes people comfort when they are

watching the outdoor unit;

New outdoor unit and indoor unit design to get a ultra high SEER/SCOP A+++/A++ which is reaching the world

class energy efciency (3U55)

The new outdoor unit takes 550mm diameter large fan design, multi split II outdoor unit can provide same air ow

but with lower fan rotation speed, then the sound level reduce 3-4 dB(A) comapred with rst generation multi split

outdoor unit;

550mm

Installation Friendly

External General Stop Valve

Easy Start Up & Maintenance

The outdoor unit takes external general stop valve in all outdoor unit design, installer can vaccum/charge just one

time with no extra dismantlement, save lots of time;

In start up & maintenance, PC monitor can connect with outdoor unit by TD-02, read all indoor unit & outdoor

unit running parameter, also with the function to show parameter & curve.

When malfunction happens, show failure code.
