The intermediate pressure performance is drastically improved by using a release valve and optimizing orbiting scroll lifting force in the improved new compression mechanism. Therefore, intermediate pressure performance is largely improved for energy-saving.
Performance is greatly improved by the high efficiency DC inverter compressor and 100% load compressor, and loss-less energy saving operation is achieved (depending on the building).
A newly developed self-demand function has largely improved energy-saving effects.
Since the current is self-detected and demand control performed automatically, no signal wiring work is required. Conventional demand control using demand signals is also available, and you can select various operations as required.
The elevator can be used to transport the base unit separately.
The piping connection work is newly available from the refrigerant piping outlet
(right bottom side of the front cover) in addition to three directions (front, rear or bottom) from the bottom base.
A new piping outlet is provided on the lower right side of the front cover and so the piping connection kit can be installed at the lower position.
This makes an easy and clear installation of the piping from multiple outdoor units possible.
Improved flexibility of design by increasing the total pipe length to 1,000 m max.

Regulating the operation time of each outdoor unit leads to load reduction on compressor.*2 During multiple unit operation, the same rotation frequency of inverter compressor results in an equivalent load on each compressor. Therefore, outdoor unit endurance is improved.
NOTES
The Backup Operation Function prevents the system from coming to a complete stop when outdoor unit failure occurs.*1 Emergency operation starts with the remote control switch after an alarm.*3
NOTES
With the new Noise Reduction Preference Mode, the sound pressure level for a particular time zone can be set based upon the usage environment.*1 Therefore, the operation/management of air conditioners is facilitated in areas where the noise level at night time is restricted by laws and regulations.
NOTES
Use this automatic judgement function to check whether or not the refrigerant amount is sufficient in one refrigerant cycle.
The appropriate refrigerant amount is calculated based upon the following data.
NOTES
The outdoor units provide external static pressure up to 60Pa by setting at site for installation on each floor of the building.
