ooling or Heating ZUBDN series PUHYHP YHM(BS) PUHYHP YSHM(BS) Bringing a year round comfort solutions to extreme climates ITY MULTI ZUBDN series combines the ultimate in application flexibility and powerful cooling and heating capabilities to deliver precise comfort even in the coldest days of the year down to 25. The technology behind this is a Flash Injection circuit which provides optimum amount of refrigerant to the system via a compressor through a specially designed injection port to ensure a particularly stable operation. With this, ZUBDN can provide a full heating performance even at 15 and continuous heating for up to 250 minutes in one continuous cycle, ensuring a phenomenal heating performance at low temperatures.

High Static Pressure Setting High Static Pressure Setting up to 60Pa is available. With our new ZUBDN model, high static pressure setting up to 60Pa is available by setting the dip switch (0Pa at factory setting) making it ideal and flexible for any type of application. Shorter Warmup in about 20 Min. With its new improved startup performance, the ZUBDN system achieves full heating capacity even when outdoor temperature is as low as 15. Heating capacity, about 20 minutes after startup is improved by 40% compared to the conventional model; ensuring occupants an immediate comfortable air solution.

Backup operation Rotation Function (HP400 and HP500 models) Running outdoor units alternatively using its newly developed Rotation Function, the system is able to ensure an optimum product life cycle for both of its component units. lternate operation Page 30
Maximum Stable Operation By utilizing our advanced Flash Injection ircuit, the system can not only provide continuous heating for up to 250 minutes in one continuous cycle, but also significantly lessens defrost time to give an exceptionally stable heating operation. Heating up to 250 min. straight Reduced Defrosting time Startup omfort One of the key factors of the units newly designed Flash Injection ircuit is that the optimal amount of refrigerant can be provided to the system via the compressor through a specially designed injection port to ensure a particularly stable operation. In simple terms, the system allows a quick startup time and continuous heating; even in low ambient conditions.
