5 Water loop connection
Please pay attention to 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 dirty and blocks. Water leakage test must be
carried out to ensure there is no water leaking. And then the insulation can be made.
Attention that the pipe must be tested by pressure separately. DO NOT test it together
with the heat pump.
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 air stayed inside of the water pipe, and there must be air vent on the top
point of the water loop.
There must be thermometer and pressure meter at the water inlet and outlet, for easy
inspection during running.
There must be expansion tank on the top point of the water loop, and the water level in
the tank must be at least 0.5 meter higher than the top point of the water loop.
6 Power supply connection
Open the front panel, and open the power supply access.
If the outside water pump is needed, please insert the power supply wire into the wire
access also and connect to the water pump terminals.
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 additional auxiliary heater is need 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.
