Step 4: Water flling and anti freezing measures
Water filling and emptying
• Before the hydraulic module is connected to the water pipeline, please check the water resistance of the
connected user water system. If the water resistance exceeds 40KPa, please increase the external circulation
pump in the total change or the branch with large water resistance. If a mixed water pump has been installed
in the floor heating branch, there is no need to add a circulating water pump in this branch.
• For the first operation, it is recommended to rotate the pump shaft for more than 10 turns to prevent the
pump from getting stuck.
• Exhaust valve shall be set at the highest point and local highest point of water system pipeline, and drain
valve shall be set at the lowest point.
• After the indoor unit and outdoor unit are installed, confirm that the power supply is closed, loosen the vent
valve on the indoor unit, and inject water into the water system of indoor unit.
• Check the water system for leaks.
• If there is no leakage in the system pipeline, the power supply of the unit will enter the emptying mode of
the wire controller to carry out the forced operation of the water pump. Remove air in the circuit as much as
possible using the air purge valves.
When there is no “hissing” pneumat ic sound at the vent valve, close the vent valve on the indoor unit and
