Preparing for Installation

Determine the location for the RO system, RO faucet, and water storage tank.

• The faucet can be installed in a pre-drilled hole on the sink, if available. If drilling a new hole, make sure not to damage any plumbing or wiring that may be under the countertop or sink.
• The pressure storage tank can stand upright or be laid on its side.
• The storage tank and RO faucet can be up to 5 feet apart. If the tank needs to be farther away than 5 feet, we recommend a booster pump to supply adequate pressure at the faucet.

Tubing Connection Tips

Insert Tubing	Release Tubing
Push tubing in until it stops. Gently pull tubing to ensure tubing is locked in fitting.	Push in the collet. While collet is being pushed in, pull tubing out of fitting.

Installation Instructions

Warnings:

• This system is for cold water supplies only. Do NOT install the system on the hot water supply line. Hot water will damage the system.
• Installation and use must comply with all state and local plumbing codes.
• This system is for indoor use only.
• A pressure regulator is required if incoming water pressure is over 80 psi.
• It is highly recommended to shut off the water supply to the system unit when it will not be in use for longer than a week.
• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

Prepping RO:

1. Remove all components from the box. Using the Parts Checklist, verify that all of the parts are included. Once all parts have been verified, continue on to step 2.
2. Remove the filter cartridges from the filter housings and unwrap. Insert the filter cartridges into the filter housings.

   Important Note: The stage 1 and stage 3 filters are bi-directional, and can be inserted with either end leading. The stage 2 filter (SP-GAC-10R) has a clear plastic lip on one end—this plastic lip should be facing up, into the filter housing.

   

3. Ensure the O-rings on the filter housings are seated properly in the grooves.

   Important Note: Filter cartridges must go in a specific order:

   • Stage 1 (SP-AP110)
   • Stage 2 (SP-GAC-10R)
   • Stage 3 (SP-CBC-10)

   Hand tighten the filter housings back onto the RO system in a clockwise direction. Use the filter wrench to tighten filter housing 1/4 turn, or until it is snug.Do not overtighten the filter housings.

   *Once your RO system is in service, if a filter housing is leaking, use the filter housing wrench to tighten. Do not overtighten the filter housings. Overtightening may damage the O-ring(s), cause water leaks, or affect overall system performance.

4. Disconnect the tubing from the fitting on the 4th stage RO membrane housing cap.

   

5. Remove the end cap from the housing by turning it counterclockwise as shown below:

   

6. Insert the RO membrane cartridge into the housing. Ensure that the O-rings on the water tube of the cartridge are fully seated in the membrane housing (the cartridge will be seated flush with the housing). Make sure that the brine seal on the membrane seals without gaps or wrinkles inside of the housing.

   

7. Make sure the O-rings on the housing and in the housing cap are properly seated. Replace the housing end cap, using the housing wrench to tighten. Do not overtighten.
8. Reconnect the tubing, using the push fitting to insert it back into the membrane housing cap.

Important Note: It is strongly recommended that you flush the Stage 1-3 pre-filters separately from the RO membrane. Flush the system for about 5 minutes and discard all water prior to installing the RO membrane, or refer to the “Replacing Filter Cartridges” section for instructions on by-passing the RO membrane.

Feed Water Adapter Installation

Attention: The water supply line to the system must be from the cold water supply line only. Hot water will severely damage your system. Use the provided metal adapters to fit the feed water adapter to your existing water line.

1. Turn off the cold water supply to the faucet by turning the angle stop valve completely off.
2. Open the cold water sink faucet to relieve pressure from the water line.
3. Prior to disconnecting the faucet connector, lay down a bowl or bucket to catch any water drips. Unscrew the kitchen faucet connector pipe from the cold water supply valve.
4. Ensure the O-ring is seated inside the feed water adapter on the female end, using provided metal adapters as required, and connect it to the cold water supply. Tighten using a wrench or pliers.
5. Check that the O-ring in the kitchen faucet connector pipe is still properly seated. Connect the kitchen faucet connector pipe onto the male end of the feed water adapter, using provided metal adapter as needed, and tightening with a wrench or pliers.
6. Remove the blue locking clip from the feed water adapter. Insert the 1/4" white tubing that goes to the reverse osmosis system. Reinsert the locking clip.

   

   

Faucet Installation

Note: Some sinks have pre-drilled 1" holes that are suitable for installation of your Drinking Water faucet. If your sink has such a hole, skip to the faucet installation instructions.

Notice: Please refer to recommendations from the countertop or sink manufacturer or a professional for drilling a hole in a countertop or sink. The RO system manufacturer and supplier do not accept any responsibility for damage resulting from installing faucets in any surface, including but not limited to granite, marble, or porcelain sinks.

Recommendation for granite or marble countertops, porcelain sinks, and other surfaces: ALWAYS use a qualified professional for drilling a hole because these materials can crack and chip easily during the process.

SP-FC100 Faucet Installation Instructions



1. Gather and identify the faucet pieces from the faucet parts bag and system parts bag.
2. Start by sliding the escutcheon onto the bottom of the faucet, lining up the holes on the base plate with the 3 inlet/outlet port stems on the faucet. The escutcheon has the rubber O-ring preinstalled.
3. (Air Gap Installation Only) Before mounting the faucet, install the waste water tubing on the faucet. The 1/4” blue filtered water tubing is already connected for convenience. First, push the 1/4" black wastewater tube onto the smaller, 1/4" air gap barb fitting at the bottom of the faucet, making sure to push it at least 1/2" up the fitting.
4. (Air Gap Installation Only) Push the 3/8" red wastewater tube onto the 3/8" air gap barb fitting at the bottom of the faucet, making sure to push it at least 1/2" up the fitting.
5. Insert the blue, red, and black tubing and the stem through the pre-drilled hole.
6. From the underside of the sink, slide on the slotted metal washer, spacer, star washer, washer, and mounting nut.
   • Check the orientation of the faucet, then tighten the locking nut securely with a wrench. Do not overtighten fittings.
   • (Optional) Install the spacer if the countertop is less than 1/2" thick (e.g., a stainless steel sink). You do not need a spacer if your countertop thickness is 1/2" or more.
7. Connect the 1/4” blue filtered water hose to the outlet on the RO membrane.
8. (Air Gap Installation Only) Connect the other end of the 1/4" wastewater line to the RO system’s wastewater output port.
9. (Air Gap Installation Only) Connect the other end of the 3/8" wastewater line to the drain saddle.
10. Flush the faucet with water and check for leaks.

SP-FC210 Faucet Installation Instructions



1. (Air Gap Installation Only) Before mounting the faucet, install the water tubing on the faucet. Begin by pushing the 1/4" wastewater tube onto the smaller, 1/4" barb fitting at the bottom of the faucet, making sure to push it at least 1/2" up the fitting.
2. (Air Gap Installation Only) Push the 3/8" wastewater tube onto the 3/8" barb fitting at the bottom of the faucet, making sure to push it at least 1/2" up the fitting.
3. Slide the escutcheon base of the faucet up over the water lines, and insert it into the bottom of the body of the faucet.
4. Insert the faucet lines and stem into the hole on the countertop or sink. For the next few steps, it may be easier if you have a second person hold the faucet in position above the counter.
5. Underneath the counter, insert the black rubber washer in the proper position over the water lines and faucet stem, making sure to line up the pieces with the hole on the washer.
6. Slide on the metal washer against the rubber washer and then slide up the plastic spacer. It may be easier to try and mount both pieces simultaneously.
7. Screw the black lock washer wing nut onto the threaded faucet stem under the metal washer or optional spacer, making sure to tighten but not overtighten.
8. Depending upon the size of your undersink water filter’s filtered water hose, screw the 1/4" or 3/8" union adapter onto the end of the threaded faucet stem. Be sure to tighten but not overtighten.
9. Connect the filtered water hose from the undersink water filter system to the union adapter.
10. (Air Gap Installation Only) Connect the other end of the 1/4" wastewater line to the RO system’s wastewater output port.
11. (Air Gap Installation Only) Connect the other end of the 3/8" wastewater line to the drain saddle.
12. Flush the faucet with water and check for leaks.

Mounting the Drain Saddle

Warning: The drain saddle creates a wastewater connection with the sink drain and is designed to fit a standard 1-1/2" OD drain pipe. Drain saddles should always be installed at least 1-1/2" above the nut of the p-trap on a vertical or horizontal drain. Do not install near a garbage disposal. Take extreme caution to only drill through one side of the drain pipe.

1. Locate a spot at least 1-1/2" above the nut of the p-trap on the drain pipe that is convenient for installing the drain saddle. It is recommended to install on horizontal piping to minimize dripping noise.

   

2. The small, square, black foam gasket with a circle cut out of the middle must be applied to the inside of the drain saddle. Remove the backing and stick to the drain saddle as shown.

   

3. Using the 3/8" drill bit, drill into only one side of the drain pipe. Do Not drill through both sides of the pipe.
4. Assemble the drain saddle around the drain pipe and align the opening with the hole drilled in the previous step - you may use a small screwdriver to feed through the drain saddle hole to aid with the alignment.

   

5. Measure the 3/8" red tube from the faucet to the drain saddle on the drain pipe and make a straight cut to the correct length.

Notice: The red 3/8" drain tube to the drain saddle must be as SHORT and STRAIGHT as possible. Make sure there is a downward slope from the faucet to the drain saddle to allow for proper drainage without causing the tube to stretch or sag.

Tips:

1. If tubing is looped, it can cause water to come out of the air gap faucet.
2. Looped tubing can shorten the life expectancy of the RO membrane.

   

Installing the Storage Tank Valve

Warning: Do not adjust the air valve on the storage tank. It has been preset to 8-10 psi by the manufacturer.

1. Remove the plastic stand at the top of the tank.
2. Use the Teflon tape to wrap the 3/8" fitting at the top of the tank 6 times.
3. Place the storage tank on its stand in the desired location, and position either horizontally or vertically.

   

4. Insert the yellow tubing from the 5th stage (Post Carbon Inline Filter) into the storage tank valve, about 1/2" deep (see the Advanced 5-Stage RO Filtration Process diagram for reference).
5. Turn off the storage tank valve.

   

Installing the Leak Stop Valve

Note: When the leak stop valve detects a leak, it will automatically shut off the inlet water to the RO system, protecting your home from potential water damage.

Warning: The valve is highly sensitive to water. Please install with caution, as the leak stop pad easily absorbs water and will require replacement every time it comes into contact with water.

1. Find a dry, flat surface next to the RO system to place the leak stop valve.
2. Screw the leak detector to the cabinet floor or utilize the double sided tape to mount to the cabinet floor.

   

3. Measure from the feed water adapter to the leak detector inlet and cut the 1/4" white inlet tubing.
4. Connect the tubing from the feed water valve to the inlet port of the leak stop valve.
5. Measure from the outlet of the leak detector to the 1st stage pre-filter housing.
6. Connect the 1/4" white tubing from the outlet port of the leak stop valve to the inlet port on the 1st stage sediment pre-filter housing.

Starting the System

Warning: Make sure all tubing has been properly connected. Check that all of the connections are secure before turning on the water supply. The leak detector cartridge should be installed after initial system startup. This is to ensure the leak detector cartridge does not need to be replaced during startup due to tubing that is not inserted properly or a loose housing. Refer to the checklist on the next page and diagram below:

• The blue faucet tubing connects to the 5th stage post-carbon inline filter.
• The white water-supply feed tubing connects to the 1st stage sediment cartridge housing.
• The yellow storage tank tubing connects to the 5th stage post-carbon inline filter at the union tee fitting.
• The 1/4" black wastewater tubing from the RO faucet connects to the flow restrictor.
• The 3/8" red wastewater tubing from the RO faucet connects to the drain saddle.

1. Close the storage tank valve.
2. Turn on the cold water supply and the undersink adapter valve. If leaks are present, turn off the cold water supply valve and correct the problem before proceeding.
3. Open flush valve for 3 minutes to purge RO membrane. Close flush when completed.

   

4. Turn on the RO faucet to release any air from the system.
5. After several minutes, water will begin to drip or trickle from the RO faucet.
6. Let it trickle for approximately 10 minutes, then turn off the RO faucet.
7. Turn on the storage tank valve. It will take 1 to 3 hours for the storage tank to fill, depending on your home’s water pressure. You will know the tank is full when you hear the water stop running to the drain pipe.
8. After the tank is full, flush the system by turning on the RO faucet until the water in the tank is completely discharged.

Warning: Do NOT drink the first tank of water produced by the system. We recommend refilling and flushing the tank twice before use.

9. After the tank is emptied, turn off the RO faucet and allow the tank to refill. Refilling will usually take 1 to 3 hours.
10. Turn on the RO faucet and allow the tank to flush once more.
11. Turn off the RO faucet and allow another 1 to 3 hours for the tank to refill.
12. Once you have determined the RO system has no leaks, close the feed water adapter valve, open the leak detector drawer, and install the cartridge/pad. Close the leak detector drawer and open the feed water adapter valve.

    

13. After the tank has refilled for a third time, you can begin to enjoy your clean, freshly filtered water.

Check daily for leaks during the first week of use. Check for leaks periodically after the first week.

Water may be milky or cloudy during the first week of use. This is caused by air bubbles in the water and is normal. The water is completely safe to drink and use.
