Unit features

Installation
Inspection before trial running
Check the indoor unit, and make sure that the pipe connection is right and the relevant
valves are open .
Check the heat pump unit including all of the screws and parts of the heat pump to see if
they are in good order. When power on, review the indicator on the controller to see if
there is any failure indication. The gas gauge can be connected to the check valve to
see the high pressure(or low pressure) of the system during trial running.
Check the water loop, to ensure that the water inside of the expansion tank is enough, the
water supply is good, the water loop is full of water and without any air. Also make sure
there is good insulation for the water pipe.
Check the electrical wiring. Make sure that the power voltage is normal, the screws are
fastened, the wiring is made in line with the diagram, and the earthing is connected.
Trial running
Start the heat pump by press " " key on the controller. Check whether the water pump is
running, if it runs normally there will be 0.2 MPa on the water pressure meter.
When the water pump runs for 1 minutes, the compressor will start. Hear whether there is
strange sound from the compressor. If abnormal sound occurs please stop the unit and
check the compressor. If the compressor runs well please look for the pressure meter
of the refrigerant.
9 Trial Running
Then check whether the power input and running current is in line with the manual. If not
please stop and check.
Review whether the outlet water temperature is stable.
The parameters of the controller are set by the factory, it is not allowed to change then
by user himself.
Adjust the valves on the water loop, to make sure that the hot(cool) water supply to each
door is good and meet the requirement of heating(or cooling).
8 Transit
When the unit need to be hung up during installation, a 8
meters cable is needed, and there must be soft material
between the cable and the unit to prevent damage to
the heat pump cabinet. (See picture 1)
WARNING
DO NOT touch the heat exchanger of the heat pump with fingers or other objects！
Picture 1

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.

fastened, the wiring is made in line with the diagram, and the earthing is connected.
Trial running
Start the heat pump by press " " key on the controller. Check whether the water pump is
running, if it runs normally there will be 0.2 MPa on the water pressure meter.
When the water pump runs for 1 minutes, the compressor will start. Hear whether there is
strange sound from the compressor. If abnormal sound occurs please stop the unit and
check the compressor. If the compressor runs well please look for the pressure meter
of the refrigerant.
9 Trial Running
Then check whether the power input and running current is in line with the manual. If not
please stop and check.
Review whether the outlet water temperature is stable.
The parameters of the controller are set by the factory, it is not allowed to change then
by user himself.
Adjust the valves on the water loop, to make sure that the hot(cool) water supply to each
door is good and meet the requirement of heating(or cooling).
8 Transit
When the unit need to be hung up during installation, a 8
meters cable is needed, and there must be soft material
between the cable and the unit to prevent damage to
the heat pump cabinet. (See picture 1)
WARNING
DO NOT touch the heat exchanger of the heat pump with fingers or other objects！

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.
