6 General Information
Compressor
(Twin Rotary) structure
3.2 High efficient DC inverter compressor
Full DC inverter mini VRF adopts highly intelligent inverter-driven compressor. This advanced technology enables the output of
the outdoor unit to be modulated by the real heat load demands..
This advanced system ensures precise temperature regulation and highly efficient energy usage, making a significant
contribution to the limiting the impact on the environment.
3.3 High performance heat exchanger
The new designed window fins enlarge the heat-exchanging area,
which decrease the air resistance, save more power and enhance heat
exchange performance.
Hydrophilic film fins and inner-threaded copper pipes optimize heat
exchange efficiency.
3.4 Low-operating sound design
Optimally design fan shape and new designed discharge air grille and air deflector, making higher air volume
and lower operation sound.
3.5 Quick warm-up & cool-down design and less temperature fluctuation
Utilizing the inverter compressor benefits,
the system can reach full load quickly and
shorten warm-up or cool-down time for an
immediate comfortable air solution.
Less temperature fluctuation will create a
better living environment. Used across entire range of models.
Efficiency improvement by up to 45% especially at low speed.

3.6 Wide operation temperature range
No matter in extremely cold winter when outdoor
temperature gets as low as -15°C or in hot summer
when temperature is up to 48°C, the mini VRF
system will keep stable performance.
3.7 Flexible piping design
3.8 Flexible indoor unit’s connection
Mini VRF with intelligent control gives you independent zoning control with maximum flexibility.
A single outdoor unit supports up to nine indoor units, freeing up considerable space outside. Use your
backyard more wisely with much more space available created by less number of outdoor units.
Max. 4 indoor units for a 80 model outdoor unit installation
Max. 5 indoor units for a 105 model outdoor unit installation
Max. 6 indoor units for a 120 model outdoor unit installation
Max. 6 indoor units for a 140 model outdoor unit installation
Max. 7 indoor units for a 160 model outdoor unit installation
Max. 9 indoor units for a 180 model outdoor unit installation
3.9 Simple signal line connection
Installation is much easier as the communication wiring between indoor & outdoor units can be shared.
It’s easy for the user to retrofit the existing system with a centralized control by simply connecting to
outdoor unit.
3.10 Auto address setting function
The addresses of indoor units can be set automatically by outdoor unit.
Wired controller and wireless controller can enquire and modify the address of each indoor unit.

8 General Information
3.11 Easy piping connection
Offering four directions to connect pipes and wirings
to meet various installation requests.
3.12 Easy installation
The mini VRF can be transported by elevator which makes
installation dramatically easy, and effectively reduces time
and labor thanks to the small size.
3.13 Easy maintenance
Forced cooling button makes outdoor unit run in cooling mode at
any condition, so it is very easy for you to charge refrigerant to the
system when it needs to be done. The self-diagnosis function
detects malfunctions in major locations in the system and displays
the type of malfunction and location. This allows service and maintenance
to be performed more efficiently.
3.14 Space saving
The Mini VRF units are more compact, resulting in significant savings in installation space. It is particularly
suitable for small offices, villas, shops, etc.
