  • Installation of the pipe for PT valve: The spec of the valve connecting thread is RC3/4" (internal thread). After installation, it must be confirmed that the drainpipe outlet is exposed in the air. When flexible drainpipe is jointed to the pressure relief orifice of this valve, it must be confirmed that the flexible drainpipe is downwards vertically and exposed in the air.

Installation & Owner's Manual

NOTE

A safety valve should be installed at the water inlet of the unit. Arrange water pipes and which connected fittings as illustration of the above figure. In case of install it at a place where outside temperature below freezing point, insulation must be provided for all hydraulic components.

•The handle of PT Valve should be pulled out once per half year, to make sure that there is no jam of the valve.

Please beware of burn, because of the high temperature of water. The drainage pipe should be well installed ,in order to avoid freezing up in cold weather.

  • Do not press the handle of PT Valve Do not dismantle the PT Valve,
    • Do not block off the Drainage pipe.

It will cause explosion and injury, if do not comply with the above instruction.

  • Installation of the One Way Valve: The spec of the One Way Valve thread in accessories is RC3/4". It is used to prevent backflow of water.
  • Installation of the Y-shaped filter: The spec of the Y-shaped filter thread in accessories is RC3/4". It is used to filtrate inlet water.
  • After all the pipes installed turn on the cool water inlet and hot water outlet and start effusing the tank. When there is water normally flowing out from water outlet, the tank is full. Turn off all valves and check all pipes. If there is any leakage, please repair.
  • If the inlet water pressure is less than 0.15MPa, a pressure pump should be installed at the water inlet. For guarantee the long safety using age of tank at the condition of water supply hydraulic higher than 0.65MPa, a reducing valve should be mounted at the water inlet pipe.
  • Probably may cause water leakage because of blockage during the drainage, pit is suggested to use a water collector as instruction in Fig 5-2 .

Solar Energy Coil Electrical Control Instruction

The mainboard of machine has two dedicated ports use for connecting to the solar thermal, they are CN17 ON/OFF port and CN18 Feedback port. The ports ensure heat pump and solar thermal won't work together.

■ Among them, the CN17 ON/OFF port is used for receiving the control signal of the solar energy water heating system, this signal needs to be voltage free switch signal. When the control signal is closing signal, the heat pump system will be locked and can't open to heat; when the control signal is open circuit signal, the heat pump system will be relieved its locked state, and the unit will judge to open or shut down according to the unit's own condition.

■ The CN18 Feedback port is used to send the feed backing of open/stop situation to the solar thermal, this port feeds back the high and low level signals. When both sides of the terminal is low level (0V) for outlet, means that the heat pump unit is under open state; when both sides of the terminal is high level (5V) for outlet, means that the heat pump unit is under shut down state.

Page 9

Which need to be declared is that the heat pump unit only receives and provides the above two signals, the control software needs to be wrote according to the entire water heating system control while designing the project installation.

■ Be caution, as the water tank can automatic recover temperature protection switch TCO when operating temperature is 78°C, and the operating temperature for the manual recover temperature protection switch is 85°C, when the water temperature of the solar thermal which enter the water tank coil is over heated (higher than the operating temperature of the TCO), it will lead to TCO operates and every part of the machine loads, include the power of the main control board, the display screen will be cut off, so please be sure the water temperature of the solar thermal which enter the water tank coil won't be over heated.

  • How to Change the Anode rod
  • Turn off the power, and turn off the water inlet valve.
  • Open hot water tap, and decrease the pressure of the inner container.
  • Open the temperature pressure valve, and drain out the water, until there are no water flow out of.
  • Get off the anode rod according to instruction.
  • Replace with a new one, and make sure effective sealed
  • Open cold water valve until hot water flows out, and turn off the hot water tap.
  • Restart and can be used normally
10.2 Non-error Malfunction

3-min Protection

With the power supplied, an immediate restart after the shutting down will have to wait 3 min as to protect the compressor.

  • If self-protection happens and the system stops, check :
  • When the power indicator lights up, if the system is forced to run while startup requirement has not been met:
  • If the air outlet or inlet is jammed or strong wind blows to air outlet.
Defrosting

When it is humid and cold, the evaporate may defrost and the water-heating capacity decrease. And the system will stop heating water and start defrosting and then restart water-heating

  • During defrosting, fan stops working, four-way valve reverses the flow direction, and compressor keeps working.
  • The defrosting time varies from 3min to 10min according to the ambient temperature and the frost.
  • Temperature Display
  • When the system stops, a decrease of the temperature is normal as heat released. When it decreases to some point, the system will restart automatically;
  • During water-heating, the displayed water temperature might still decrease or not increase for a period of time because of the heat exchange of the water. When the whole tank of water has reached the set temperature, the system will stop automatically.
