Considering local climate conditions, space restrictions, and insulation leve required cooling (heating) capacity per square meter. Compute the total capacity needed for the whole area.
Then choose the suitable heat pump's model, considering their temperature requirements and outputs specified below:
Cooling Only Unit
Chilled water outlet temperature: 5-15ºC Maximum ambient temperature: 43ºC
l, calculate the
Heating and Cooling unit
Cooling chilled water outlet temperature: 5-15ºC Maximum ambient temperature: 43ºC

04. Installation
Inverter Air Source Heat Pump (AHGR410AW) - Installation and Instruction Manual
4.3 Installation Conditions
• The unit can be installed on any area outdoors such as terrace, rooftop, and ground as long as it can carry heavy machinery.
• The location must have good ventilation.
• The place must be free from direct heat and flames.
• A shelter is needed in winter to protect the equipment if exposed to snow.
• There must be no obstacles near the air inlet and outlet of the heat pump.
• There must be an available water channel around the equipment to drain the condensing water.
• The area must be protected from strong winds.
• There must be enough space around the unit for maintenance.
4.4 Machine Foundation
The heat pump can be installed onto a concrete base by expansion screws, or onto a steel frame with rubber feet that can be placed on the ground or rooftop. Make sure that the unit is placed horizontally.
4.5 Water Loop Connection
Please consider the following when installing the water pipe connection:
• Try to reduce the resistance on the water through the piping.
• The piping must be clean and free from dirt and debris. Water leakage test must be carried out before insulating to ensure that there will be no water leaking.
• Pipe pressure must be tested separately. DO NOT test it together with the heat pump.
• There must be an expansion tank at the top point of the water loop, and the water level in the tank must be at least 0.5 meters higher than the top point of the water loop.
• The flow switch must be installed inside the heat pump. Ensure that the wiring and action of the switch is normal and controlled by the controller.
• Avoid air staying inside of the water pipe. There must be an air vent at the top point of the water loop.
• There must be a thermometer and a pressure gauge at the water inlet and outlet for easy inspection during operation.
4.6 Power Supply Connection
• Open the front panel, then open the power supply access.
• The power supply must go through the wire access and be connected to the power supply terminals in the controlling box. Then connect the 3-signal wire plugs of the wire controller and main controller.
• If the outside water pump is needed, please insert the power supply wire into the wire access as well and connect to the water pump terminals.
• If an additional auxiliary heater is needed to be controlled by the heat pump controller, the relay (or power) of the auxiliary heater must be connected to the relevant output of the controller.

4.9 Trial Run
Inspection before the Trial Run Trial Run
• Check the indoor unit and make sure that the pipe connection is correctly installed and the relevant valves are open.
• Check the water loop and ensure that the water inside the expansion tank is enough, that the water supply is good, and that the water loop is full of water without any air. Also make sure that the water pipe is well-insulated.
• Check the electrical wiring. Make sure that the power voltage is normal, that the screws are fastened, that the wiring is connected in accordance with the diagram, and that the earthing is connected.
• Check the heat pump unit including all of the screws and parts of the unit to see if they are in good order. Upon powering on, review the indicator on the controller to see if there is any failure indication. The pressure gauge can be connected to the check valve to see the pressure of the system during the trial run.
• Start the heat pump by pressing key on the controller. Check if the water pump is running. If it is running normally, there should be a reading of 0.2 MPa on the pressure meter.
• After the water pump runs for 1 minute, the compressor will start. Listen if there is a strange sound from the compressor. If an abnormal sound occurs, please stop the unit immediately and check the compressor. Otherwise if the compressor is running normally, please look at the pressure meter of the refrigerant.
• Then check whether the power input and running current is in line with the manual. If not, please stop and check.
• Adjust the valves on the water loop to make sure that the hot (or cold) water supply through each door is good and meets the requirement of heating (or cooling).
• Check if the outlet water temperature is stable.
• The parameters of the controller are set by the factory. The user is not allowed to change them on their own.

8.2 Appendix 2 – Installation of the Automatic Fill-water Valve
1. When installing the automatic fill-water valve, the arrowhead orientation
of inlet water must be in accordance with the orientation of the valve;
2. Automatic fill-water must be adjusted in advance to 1.5 bar;
3. If the pressure of inlet water needs to be re-adjusted, please follow the
following procedure:
• Open the screw cap (C).
• If the pressure of the water supply needs to be reduced,
loosen the screw (B).
• If the pressure of the water supply needs to be increased,
tighten the screw (B).
• If the system needs to be filled with water, wrest the handle (A) before
filling. Then return and close the handle once the system is full of water.
• The automatic fill-water valve needs to be cleaned regularly. Before
cleaning, close the tap, unscrew the plug (D), and remove the inside filter net. Please assemble them again after cleaning
NOTICE: There are two available connections for the pressure meter at the center of the automatic fill-water valve. The screw cap (C) must be tweaked after adjusting the fill-water pressure.
8.3 Appendix 3 – Installation of the Leakage Pressure Valve
1. The action pressure of leakage pressure valve is more than 3bars and
the pressure cannot be adjusted.
2. The valve will open automatically to make sure that the water loop
of the airconditioning system is safe when the water pressure in the backwater side is higher than the set pressure.
8.4 Appendix 4 – Assistant Heat Sources
The unit allows for the connection of an assistant heat source, which can be a gas-fired boiler or an electronic boiler. The possible schematic diagrams for their connection are as follows:
