Select pipe material, can choose stainless steel, copper, aluminum hot water pipes, hot water PPR
pipes, etc., with pipes in national health and safety standards, heat-resistant, rust-proof, not easy to
scale.
◆
Reasonable pipe layout, to minimize bending and reduce the pressure loss of the water system.
◆
After the circulating water system connected, must do pipeline connection rigidity and add water
pressure inspection, and sewage, to ensure the system clean. Past the inspection,no leakage, then pack
insulation for pipeline and valves.
◆
Metal pipe must use with more than 50mm thick glass fiber or high density, fire-retardant insulation
sponge. (PPR hot water pipes can be used 30mm thickness of glass fiber or high density fire-retardant
sponge rubber insulation.)
◆
Must install thermometer and water pressure gauge on Inlet and outlet water pipes,to inspect during
operation.
