---Flexible high-efficiency scroll compressor, which patent flexible design provides best ability of fluid-attack resistance and impurity tolerance.
---Continuous compression output ensure the pulse of air flow to be reduced, with low vibration noise
(2)High Efficiency Air Side Heat Exchanger
---Special shaped design, inner grooved patent sawtooth design and aluminum fin guarantee efficient heat exchange between the air side exchanger and ambient air.
(3)High Efficiency Water Side Heat Exchanger
---Tube in shell tank type: Optimize design of both inner and outer screwed tube, it helps to increase heating exchange efficiency, and provide better heating capacity. The special design of liquid refrigerant circulating tube on the bottom of condenser ensures the heat pump system run smoothly in severe working condition.
---Brazed-plate evaporator made from stainless steel features a brand-new diagonal design to better utilize heat exchanging surfaces.
---Shell and tube evaporator with inner grooved cooper tubes optimizes the cooling and heating efficiency.
Self-cleaning,high intensity,anti-shaking design and heat insulation covering material ensure shell and tube heat exchanger unstained,reliable,quiet,highly efficient.


(4)Throttling Device
Adopt superior quality famous exterior balanced thermal expansion valve or capillary type throttling device, which is high reliability and adjustability, can realize precise refrigerant and temperature control to ensure operating in precise and reliable status.


(5)Axial fan
Adopt famous brand axial fan,compact structure,which is accord with aerodynamic principles; falciform impeller which can assure it runs with high efficiency and low noise,also can keep a better aerodynamic performance even under a short air inlet condition.
(6)Intellectualized Controller
Adopt micro computer control, can operate via centralized manage system; whole system can realize remote operation. The system can monitor the water temperature, capacity status while running. The water temperature can be controlled according to the water outlet temperature.

10. Installation instruction or installation photo, project photos


A,Place selection of installation Heat pump
 1). Heat pump should be installed in a large space, and have good air flow condition.
 2). Air inlet and outlet must be a clear road, the distance from barrier to inlet and outlet must be longer than 2m.
 3). Set drain ditch or drain outlet, so that can drain water easily.
 4). The installation base or bracket must be firm, make sure heat pump work balancely.
 5). Make sure heat pump is vertical, can't be slanted.
 6). Don't install heat pump at the place in where there is plenty of pollutional and corrosive gas or sand or fallen leaves.
 7). The installation place can't be near inflammable, flammable thing or fire.
 8). Installation:
---The installation base can be concrete construction, or steel bracket, and must use anti-vibration rubber pad, And the surface should be smooth.
---The design of installation base can be according to heat pump weight.
---The heat pump bottom should be fixed by bolt.
B,Pipe connection
The drain pipe and overflow pipe should be installed near drain ditch or drain outlet, easy to drain, and install drain water valve on drain pipe before magnetic valve there should be service valve on water pipe.
 If use plastic pipe (such as PPR pipe or ABS pipe), users should consider pipe expand and contract problem between heat pump and water tank.
 Water supply valve and cut-off valve maybe need insulation (according to local weather condition),avoid frost crack.
C,Water pipe system installation
Water pipe should be straight, and the arrange should be reasonable, reduce bend as little as possible. Reduce the water pipe resistance.
There can't be leaking at any place of pipe.
After all equipments and pipes installation finished, users should test water pressure, and drive air out, drain dirty out, make sure water cycle system is  clean. After confirm there is not any problem, then insulate all hot water pipes.
D,Power supply wiring
 220V heat pump use single phase power supply, 380V heat pump use three phase power supply, wire line is 3phase 4lines, A B C connects live line, N connects null line, E connect earth. Be sure not to connect N line to live line of power supply.
 1).When repairing, please turn power supply at "off" side.
 2).Power supply connecting process:make sure a equipment power supply is cut off before its installation is finished. Install power supply switch at suitable place, Use rubber hole for wiring line in electric box.
Power supply demand:
220V rated voltage±10%
380V rated voltage±10%
frequency:50Hz rated frequency±2%
 3).if power supply fluctuation is out of demand, please don't start your heat pump.
