Safety Control
Protection devices such as dual pressure protection and overload protection etc. is provided to ensure
unit operating within safety condition range. The microprocessor-based controller automatically directs
system on or off by processing the water temperature feedback. If the water temperature falls to
unacceptable low point, the controller automatically shut off the system to prevent hydraulic system
internal freeze for unit safety operation. Meanwhile, the microprocessor-based controller automatically
monitors every component operating status and malfunction, and feedback it to indoor controller to
greatly ease the work of status monitor and troubleshooting.
All Weather
The cabinet is made of electro galvanized mild steel sheet, coated with baked polyester power to ensure
the units extra durability in all climates against sun, rain, wind corrosion.
Space saving (small footprint) design of the machine eliminates large installation area requirement, no

The machine uses high quality parts to ensure durability in various climate conditions.
Simple to Maintain
The simple design of the machine allows for maximum serviceability. All components are with reach of
the maintenance personnel upon open up of the servicing panel. If emergency shutoff occurs, the
