Elbow Fittings (#4044K): Quick-connect elbow ttings for the system, with a 1/4" tubing
connection and 1/4" NPT male thread (excluding membrane housing and cap).
Feed Water Adapter (#AFW43): Connects to the cold water line, branching a supply to the
RO system; compatible with 3/8" COMP and 1/2" NPT connections.
Feed Water Solenoid Valve (#ASOW7): Controls water ow to the booster pump, activating
when both the low-pressure and high-pressure switches are on.
Flow Restrictor (#AFR200): Regulates wastewater
ow to maintain system pressure,
ensuring e ective RO processing.
Flow Sensor Switch (#FSS): Activates the UV lter as needed by detecting water ow.
GAC Filter (#FG15): 2nd stage, 5-micron granulated activated carbon lter that reduces
chlorine, taste, and odors.
GPD: Gallons Per Day ( ow rate measurement).
High-Pressure Switch (#AHP1): Activates at tank pressures below 20 psi and deactivates at
45 psi, controlling the booster pump.
Housing Wrench (#AWR2): Tool for loosening and tightening the membrane and stages 1-3
lter housings.
Ice Maker Kit (#ICEK): Connects RO water to refrigerator ice makers or water dispensers.
Leak Stopper (#ALS1): Prevents potential leaks by shutting o the water supply if water is
detected by its sponge.
Low-Pressure Switch (#ALP1): Activates when source water pressure reaches 6 psi and
deactivates if it falls below this threshold.
Membrane Housing and Cap (#NW12): Horizontal housing unit for the RO membrane.
Membrane Housing O-Ring (#ORM): 2.5" O.D. O-ring that seals the membrane housing and
cap.
Post Carbon Filter (#FT15): 5th stage lter that polishes the water before it reaches the
faucet.
PPM: Parts Per Million, used to measure TDS readings.
