General
Information
1.3 High reliability
1.3.1 Cycle duty operation
In one combination, any of the outdoor unit can run as the master unit and master unit can cycle in a period, to
realize the equal lifespan among the outdoor units. As a result extend the system lifespan significantly.
1.3.2 Backup operation
In a multiple system, if one module is failed, other modules can be backup instead of the failed one for
continuing operation.
1.3.3 Precise oil control technology
5 stage oil control technology ensures every outdoor unit & compressor’s oil always keep in the safe level,
completely solve the compressor oil lack problem.
1st stage: compressor internal oil separate
2nd stage: high efficiency oil separator (separation efficiency up to 99%)
3rd stage: oil balance technology between compressors
4th stage: oil balance technology between modules
5th stage: intelligent system oil return program
1.3.4 Intelligent soft start technology

(Sec)
All the DC inverter compressors start with a
very low current which will obviously reduce
the strike to the electric network and make
the system more reliable and stable.
