    INSTALLATION 6.2.5 Debug the indoor refrigerant system • When finish the connection, please release a little refrigerant from the Refrigerant outlet, or use the vacuum pump to vacuum the system, until the pressure is below 70Pa. • Once the system has been vacuumed, please open the Refrigerant inlet and the Refrigerant outlet until the pressure is balanced, and then check the joints with suds.
  • Page 16: Install Heat Consumer System

    INSTALLATION • Keep the water pipes straight and the pipeline allocation reasonable. Reduce pipe turnings as many as possible to reduce water resistance. • Prevent the pipeline and the connectors from water leakage. • The water pressure bearing capability of each part of the piping system should be tested after installation is finished.

    INSTALLATION 6.4.4 Oxygen diffusion Steel components, such as radiator ans pipes, can corrode if plastic under floor heating system pipes, which are permeable to oxygen, are used. The product of corrosion, for example, rusty sludge, can settle inside the heat exchanger and can result in output loss through a reduction of cross-section or in a heat pump shutdown triggered by the high pressure limiter.
