2 Brief description of the heat pump ON/OFF, for example,

Users can use the controller to adjust the parameter " 1.1" in

order to set the target outlet water temperature. When it

sensors the actual water temp is lower than the target by 5 C,

the machine start to run. The heat pump transfers the heat of

air into the water tank, makes the water temp raised. When

the sensor sensors the actual water temp is higher(or equal) to

the target, the machine stops. The heating has been finished.

There is 200L/250L/300L /400Lhot water to be used.

3 There should have installed a 0.7Mpa single pressure release

valve when install the heat pump. See Fig.

4 Lowest inlet water temp for normal working(initial water

temp): 7 C.

5. Please install a air duct pipe of 2-3 meter to air outlet on top

of the heat pump .
