Point A: Feed water inlet into Stage-1 filter (red tubing)
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 filter. This end of the T-fitting connects to the CLEAR pure water line.
Point G: T-fitting on the Stage-5 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-5 filter. Pure water leaves Stage-5 filter via this port, and flows
onto the dispensing faucet.
