The water supply must have a pressure of 2,0 bar or higher. - The piping must be appropriately insulated, consider Heat tape to protect the water piping in areas with freezing temperatures. - As the hot - water supply pipe will expand and contract, use sleeves when penetrating through concrete walls or slabs. - With buried piping, an outer cover will need to be used that has had both ends sealed to avoid any ingress of rain. - Use only heat-resistant and corrosive - resistant material to seal the pipe joints. Before connecting to the heat pump pre-assembled piping system client: Make sure the pipes are clean, otherwise: - Run water / coolant fluid through the pipe(s) of the condenser / evaporator piping systems to remove any debris inside before connecting the pipe(s) to heat pump. - Clean the filters if any debris is found.Hydraulic connection heating circuit.
