- /How to install an Air-gap Faucet (optional)
- Note: The installation instructions below are for your reference only. An air gap faucet is not included with this system.
- Drill a hole in the kitchen sink or countertop if there isn't already a spare one. Refer to the manual of the faucet when determining the size.
- Place the front plate and the rubber washer on the base of the faucet. Mount the faucet on the countertop.
- From under the sink, connect the RO system pure water output line to the faucet stem. Attach the black drain line from the RO system to the drain input barb. Attach one end of the faucet drain line to the drain output barb and the other end to the dra...

- Section 1: iSpring RO System Maintenance
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
Post Carbon Filter (#FT15): 5
th
stage. Works as a final polishing filter before the water is
delivered to the faucet
PPM: Parts Per Million, a unit used to measure TDS readings
Pressurized Holding Tank (#T32M): 3.2 gallons capacity pressurized water holding tank. The air
bladder forces the water to the drinking faucet when the faucet is opened. The tank comes pre-
pressurized and should read 7-10 psi when empty
PSI: Pounds Per Square Inch, a unit used to measure water pressure
Quick Connect Fitting: A secure, easy-to-connect, and disconnect type of fitting used on the
system. The tubing is inserted past the tiny O-ring located inside each fitting, then locked into place
by the spider lock and blue clip
Reverse Osmosis (RO) Membrane (#MC7): 4
th
stage. High rejection, 0.0001 micron, thin-film
composite (TFC) reverse osmosis membrane, the heart of the reverse osmosis process
Sediment Filter (#FP15): 1
st
stage. 5-micron 10" polypropylene sediment filter. Traps particulate
matter such as dirt, rust, and silt
Stage 1, 2, and 3 housing O-Rings (#ORF): 3 5/8" O.D. O-ring used to create the seal between
the stage 1, 2, and 3 filter housings and their respective caps
Stage 1 See-Through Sediment Filter Housing (#HC12): Transparent stage 1 housing holds the
sediment filter. The see-through housing allows for the sediment filter to be visually inspected
Stage 2 GAC Filter Housing (#HW12): Solid white housing that holds the stage 2 GAC filter
Stage 3 CTO Filter Housing (#HW12): Solid white housing that holds the stage 3 CTO filter
T Fitting on Stage 5 Post Carbon Filter (#7544K): T fitting located on the right side of the stage
5 Post Carbon Filter
Tank Valve (#ABV2K): On/off valve that screws onto the top of the tank
TDS: Total Dissolved Solids, a measure of the contamination level of a water source
TDS Meter (#TDS3): Handheld meter used to measure water quality
Transformer for Booster Pump (#ATRF5): Power supply used for the PMP5 booster pump on
residential iSpring RO systems
Tubing (#T14B / #T14W): 1/4" food grade tubing used on the system
UV Replacement Bulb* (#UVB11): Replacement bulb for the UV filter
UV Transformer/Ballast* (#UVT11A/UVT11B): Power supply for the UV filter. Indicator lights
on the ballast will only light up when water is flowing. UVF11A is for 110V power sources,
UVF11B is for 220V power sources
