Optimized cooling/heating and increased system efficiency! Liquid EEV & Turbo Inter-cooler
• Liquid EEV for increased efficiency of the system
Through Liquid EEV, controlling of valve opening has become more efficient and it achieved optimized system efficssiency and
minimized noise from the refrigerant in the indoor unit.
• Turbo Inter-cooler
High performing shell & tube type heat exchanger has been applied to secure cooling/heating efficiency. It has secured enough
subcooling to acquire reliability on long piping and it also increased cooling/heating efficiency.
Application of wide fin
High efficient heat exchanger has been applied, therefore it delays the onset of frost formation and increased heat transfer efficiency.

Reinforced corrosion resistance on the heat exchanger
To prevent corrosion of the products which is installed in saline area, corrosion resistance has been reinforced.
Long piping/High level difference technology
Longest piping length is allowed up to 175m (equivalent length) and Maximum 50m of level difference is allowed for more flexible
installation.

1-1-1 Feature (cont.)
Memory module
• Achieves world-class efficiency with hyper compressor that applies double compression technology
If outdoor unit malfunction occurs, diagnose and repair of the problem will be much quicker with the last 3 minutes worth of a data
saved before the malfunction. (With the extra memory module, 3 months worth of a data can be saved.)
Silent operation at nighttime
• When outdoor unit needs to operate more silently during nighttime, silent mode can be set from the outdoor unit option mode.
• Silent mode can be adjusted in 3 levels depending on the level of noise.

Precautions
6Samsung Electronics
Refrigerant pump-down
If you need to move/replace the outdoor unit or when there are problems on indoor units or on the pipes, outdoor unit will recover
refrigerant remaining on the pipes.

Reduced size and light weight
Compare to conventional models, size and weight of the product has been decreased while it performance is more or so the same.
Weight of the product is now 76kg, which is 44% lighter than conventional model, which makes moving and installing much easier.

Precautions

Maximum 9 indoor unit connection
1-1-1 Feature (cont.)
System check through View mode
• Through the window on outdoor unit PCB display, you can check the main system data during operation.
• Shortened maintaining and inspection
• Displaying 15 main data including high pressure of system
- Outdoor temperature
- Discharge temperature of the compressor
- Condensing temperature
• Using the DIP switch on the outdoor unit PCB, you can limit the running current of the system
Maximum 9 indoor unit connection
You may connect up to 9 indoor units on a single outdoor unit. It will allow more powerful and flexible air conditioning system
and you can select refrigerant pipe length, or number of indoor units depending on the needs for office, commercial and residential
places.

Convenient product installation
Service valve is not exposed to keep the neat appearance and pipe can be connected in 4 different directions which provide flexible
installation and maintenance services.
