4.3 Location of Install & Minimum Clearances
The heat pump can be installed onto a concrete basement by using expansion screws, or onto a steel frame with
rubber feet which can be placed on the ground or the roof. Ensure that the unit is placed horizontally.
• The unit can be installed in any place outdoors which will be able to support the weight of a heavy unit such as a
terrace, roof, the ground and any other places deemed suitable.
• The location must have good ventilation.
• The location must be free from heat radiation and other fire hazards.
• In cold climates, a pall is needed in winter to protect the unit from snow.
• There must be no obstacles near the inlet and outlet of the unit.
•
The installation location must be protected from strong winds or air.
• There must be a water channel around the heat pump to drain condensing water.
•
Leave enough space around the unit for maintenance.

4.4 Plumbing Component
Please pay attention to the below matters when the water pipe is connected.
• Try to reduce the resistance to the water from the piping.
•
The piping must be clear and free from dirt and blockage. A water leakage test must be carried out to ensure
that there is no water leaking before the installation can be made.
• The pipe must be tested by pressure separately. DO NOT test it together with the unit.
•
There must be an expansion tank on the top point of the water loop, and the water level inside the tank
must be at least 0.5meters higher than the top point of the water loop.
• The flow switch is installed inside of the heat pump, check to ensure that the wiring and action of the switch
is normal and controlled by the controller.
•
Try to avoid any air from being trapped inside the water pipe, there must be an air vent on the top point of
the water loop.
• There must be a thermometer and pressure meter at the water inlet and outlet for easy inspection during
running.
4.5 Electrical Component
• Open the front panel and 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 an external water pump is required, please insert the power supply wire into the wire access and connect
it 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 aux-heater must be connected to the relevant output of the controller.
