Point A: Feed water inlet into Stage-1 filter
Point B: Stage-2 filter’s output port .
Point C: Automatic-Shut-Off (ASO) valve. For Permeate Pumped systems, the permeate pump replaces the
ASO valve, it serves both as a pump and an auto-shut-off valve.
Point D: Stage-3 Membrane housing inlet port. Feed water from Stage-3 filter enters the Membrane at
this port.
Point E: Check Valve. The filtered water from the Membrane passes through this Check Valve
before entering the storage tank. The Check Valve blocks the tank water from back-flowing into
the membrane.
Point F: T-fitting on Stage-4 filter. This end of the T-fitting connects to the CLEAR pure water line.
Point G: T-fitting on the Stage-4 filter. This other end of the T-fitting connects to the YELLOW pure water
line which goes to the tank’s valve.
Point H: The output end of Stage-4 filter. Pure water leaves Stage-4 filter via this port, and flows onto the
dispensing faucet.
Point I: Stage-1 filter’s output port.
Point J: Stage-4 filter’s input port.
Point K: Stage-2 filter’s input port.
