3.5 Water Loop Connection
•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.
•The connection between the heat pump and the construction is best to be of a flexible type to avoid
vibration transfer. The support to the water pipe must be separate, but not rely on the heat pump unit.
•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.
•There must be drainage on the low points of the water system, and there is already drainage on the
chassis of the heat pump. There water in the system must be drained out during winter if the heat pump
is not to be used.
3.6 Electrical Wiring and Power Supply
-Open the panel and open the power line hole
-Thread the power line though the hole and connect it to the power line terminal. The three-core control
line of the remote controller shall be plugged with the three-core signal line on the main board
according to the wiring diagram.
-For an external water pump, thread the power line of the water pump through the hole and connect it
to the water pump terminals.
-If an additional auxiliary heater is needed to be to be controlled by the heat pump controller, the relay
(or power) of the aux-heather must be connected to the relevant output of the controller.
ATTN:
-The unit should use an independent power supply. Power supply voltage must be in line with the rated
voltage.
-The power supply circuit must be equipped with an All-pole disconnect device and have at least 3mm
contact opening distance.
-The wiring must be completed by a professional technician in accordance with the circuit diagram.
-Power supply circuit must have earth wire; the earth wire of power should be connected with an
external earth wire safely. The external earth wire must be in order.
-The creepage protection device must be settled in accordance with the relevant national technical
standards for electronic equipment.
-The power wire and signal wire should be neatly arranged. High voltage wires and low voltage wires
must be separated and free from any interference. These wires must also be free from any pipes or
valves on the unit.
-When all wiring is completed, the power should only be connected after a thorough double check.

3.7 Prior to Trial Operation
Check the indoor unit, make sure that the pipe connection is done correctly and that the relevant valves are open.
Check the water loop to ensure that there is enough water inside of the expansion tank, that the water supply is good
and that the water loop has no air in it and is full of water. Make sure there in 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.
Check that the heat pump, including all the screws and different parts are in good order. When the power is on, review
the indicator on the controller to see if there is any failure indications. The gas gauge can be connected to the check
valve to see the high pressure (or low pressure) of the system during trial running.
3.8 Trial Operation
Start the heat pump by pressing the “ or “ key on the controller. Check whether the water pump is running, if
it is running normally there will be 0.2MPa on the water pressure meter.
When the water pump rungs for 1 minute, the compressor will start. Hear whether there is a strange sound coming
from the compressor. If an abnormal sound occurs, please stop the unit and check the compressor. If the compressor
runs well, look for the pressure meter of the refrigerant.
Check whether the power input and running current is in line with the manual. If not stop the unit and check for why
this may be occurring.
Adjust the valves on the water loop to make sure that the hot (cool) water supply to each door is good and meets the
requirement of heating (or cooling).
Review whether the outlet water temperature is stable.
The parameters of the controller are set by the factory, the user must not change these.
3.9 Maintenance
Check the water supply and the air vent frequently to avoid lack of water or air in the water loop.
Clean the water filter periodically to keep the water good quality. Lack of water and dirty water can damage the unit.
The heat pump will start the water every 72 hours when it is not running to avoid freezing.
Keep the unit in a clean, dry place with good ventilation. Clean the heat exchanger every few months to keep a good
heat exchange rate and save energy.
Check each part of the unit and the pressure of the system. Replace any failing parts and recharge the refrigerant if
needed.
Check the power supply and the electrical system, make sure all electrical components are wired well and working.
If the heat pump is not to be used for an extended period of time, please drain all the water out. Drain the water out
from the lowest point of the heat exchanger to avoid freezing in winter. Water recharge and full inspection on the heat
pump is needed before being restarted.
The water loop of the heat pump MUST be protected from freezing in winter. Do not shut off the power supply to the
heat pump in winter. When the air temperature is below 0°C, if the inlet water temperature is above 2°C and below 4°C
the water pump will begin freezing protection. If the inlet water is lower than 2°C, the heat pump will begin heating.
