Glossary and Terms to Know
Add-On Kit (#ACL1): Filter add-on kit for adding additional in-line filters to an existing system. It
comes with quick-connect elbow fittings, filter clamps, and extra tubing
Alkaline Remineralization Filter* (#FA15): 6
th
stage. Remineralizes the RO water and neutralizes
the pH
Automatic Shut-Off Valve (#AAS2): The white, four way valve that automatically starts and stops
the system's water production through pressure signals
Check Valve (#ACV1K): One-way valve that does not allow water back into the membrane housing.
It looks like a standard fitting and is located on the RO water port of the membrane housing
CTO Carbon Block Filter (#FC15): 3
rd
stage. 5-micron 10" carbon block filter. Further reduces
any residual chlorine, tastes, and odors before the water reaches the RO membrane
Drain Saddle (#ADS1K): Attaches to your under-sink drain pipe to secure the drain tube coming
from the system
Drinking Faucet (#GA1-BN): The output source for the RO water. The faucet is a non-air gap faucet
with a 1/4" tubing connection. The optimally sized counter-top hole for the faucet is 1/2", but holes
up to approximately 1 1/2" will work
Elbow Fittings (#4044K): Quick connect elbow fittings used on the system (except the membrane
housing and cap). 1/4" tubing connection and 1/4" NPT male thread
Feed Water Adapter (#AFW43): It goes in line with your cold water line and branches off a water
supply line to the RO system. Can adapt to 3/8" and 1/2" cold water lines
Feed Water Solenoid Valve (#ASOW7): Opens the booster pump's water supply when both the
low-pressure and high-pressure switches are on. Shuts off the water supply when one or both turn off
Flow Restrictor (#AFR300): Limits the drain water flow, keeping pressure in the system and
allowing the RO process to occur
Flow Sensor Switch* (#FSS): Detects water flow to turn the UV filter on and off as needed
GAC Granular Activated Carbon Filter (#FG15): 2
nd
stage. 5-micron 10" granulated activated
carbon filter. Reduces chlorine, tastes, and odors from the water
GPD: Gallons Per Day
Housing Wrench for Membrane and Stages 1, 2, and 3 Housings (#AWR2): Housing wrench is
used to screw on and unscrew the membrane housing cap and the stage 1, 2, and 3 filter housings
Ice Maker Kit (#ICEK): Add on kit that allows you to run water from the system to your fridge ice
maker or fridge water dispenser
Leak Stopper (#ALS1): Protects from any possible leaks by cutting off the water supply when the
sponge absorbs water
Membrane Housing and Cap (#NW12): Horizontal housing that the RO membrane is inserted into
Membrane Housing O-Ring (#ORM): 2 1/2" O.D. O-ring used to create the seal between the
membrane housing and the membrane cap
Polypropylene (PP) Sediment Filter (#FP15): 1
st
stage. 5-micron 10" polypropylene sediment filter.
Traps particulate matter such as dirt, rust, and silt
Post Activated Carbon Filter (#FT15): 5
th
stage. Works as a final polishing filter before the water
is delivered to the faucet
ppm: Parts Per Million, mg/L
