AFS003 Drinking Water Installation Demonstrator Educational Training Teaching Model Sanitation Trainer 1.Description A typical household drinking water installation is fitted to the panel. A small electrical boiler for hot water and a circulation pipe with the related components demonstrate the heating of domestic hot water from the cold water supplied. Safety devices show how the drinking water pipework is protected against the backflow of waste water. A pipe system for draining the waste water is mounted on the back of the panel. 2.Technical details familiarisation with the most important components in a drinking water installation system divided into cold water side, hot water side, drain system cold water circuit with water meter, pressure reducing valve, angle-seat valve, system separator, outlets hot water circuit with system of safety devices, pressure vessel with heater, pressure reducing valve, non-return valve, circulating pump with timer, outlets drain system on rear of panel, drain pipe DN 40 with high temperature stability single handle mixer, two handle mixer, shower sprinkler, pipe vents 3.Technical data Vane impeller water meter DN20: 2.5m3/h System of safety devices, 6bar backflow preventer pressure reducing valve shut-off valve Thermal discharge safety device: 95°C Threaded heater element 3kW (in pressure vessel) Pump power consumption: 20W max. flow rate: 640L/h max. head: 1,4m max. operating temperature: 110°C Measuring ranges pressure: 3x 0…10bar 230V, 50Hz, 1 phase 230V, 60Hz, 1 phase 230V, 60Hz, 3 phases Required for operation cold water connection: 1,5bar, drain
