- 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...

Step 4: Installing the Vertical Filters: Stages 1, 2, and 3
Step 4. a. Make sure the O-ring is seated inside the
groove on top of the filter housing. A light amount
of food-grade silicone jelly may be used to help the
O-ring seal better but is not required.
Step 4. b. The filter cartridges are preserved in shrink
wrap. Note the direction sign on the sticker before
removing the wrap.
Step 4. c. When placing the filter cartridge into its
housing, make sure it is centered and the knob
protruding from the bottom of the housing fits in
the central hole of the filter.
Step 4. d. Screw the housing, with filters attached,
onto the housing caps (caps are pre-assembled on
the machine head). The cap also has a center knob
that should be inserted into the center hole of the
filter cartridge. Twist the housing on in a clockwise direction by hand, and then use the
housing wrench to tighten it another 1/4 – 1/2 of a turn. Do not over tighten. This can
cause leaks and make it difficult to unscrew the housing when replacing filters.
Step 4. e. Follow steps 4.a – 4.d to install the GAC and CTO filters. *Note* the second stage
GAC is the only filter that must go in a certain direction. Please make sure the end with the
rubber washer faces up, thereby attaching it to the housing cap.
Step 5: Installing Tank Shut-off Valve (TSV)
Step 5. a. Wrap 10 - 15 wraps of Teflon tape clockwise (when looking from above) onto the
metal thread at the top of the tank.
Step 5. b. Screw (clockwise) the Tank Shut-off Valve on and tighten it by hand. Do not over
tighten.
Step 5. c. Connect the YELLOW tubing into the Quick-fitting on the TSV.
Step 6: Installing the Reverse Osmosis Membrane
Step 6. a. First, disconnect the white tube from the quick-fitting connection on the membrane
cap. This will allow you to unscrew the membrane housing cap.
Step 6. b. All the systems are wet tested without filters before shipment, so you may notice
some water drops inside the housing.
Step 6. c. Unscrew (counterclockwise) and remove the membrane cap.
Step 6. d. Following the flow direction sign on the membrane, cut open the “small end” of the
bag, hold the membrane with the bag to avoid touching or contaminating it, and firmly
insert it into the housing. This way, the end with the two small black O-rings towards
the bottom. When it is inserted fully and correctly, the “bigger” end of the membrane will
be even with the housing opening. See Figures 12-13. After the membrane has been fully
inserted, you may then disregard the bag.
