Point A: Feed water inlet into Stage-1 filter (red tubing)
Point B: Stage-3 filter’s output port
Point C: Automatic-Shut-Off (ASO) valve.
Point D: Stage-4 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-5 UV filter. This end of the T-fitting connects to the CLEAR pure water line C4.
Point G: T-fitting on the Stage-5 UV 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-6 filter. Pure water leaves Stage-6 filter via this port, and flows onto the
dispensing faucet.
Point J: UV housing output to Stage-6 carbon filter.
Point K: The inlet end of Stage-6 carbon filter.
