4.6 Power Supply Connection
• 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.
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.
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.
• 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.
