Economical 4-stage reverse osmosis (RO) unit ensures a steady supply of purified water for large or multiple aquariums. Aquatic Life RO Junior 4-Stage Reverse Osmosis System is a smart RO choice producing up to 100 gpd of economically filtered reverse osmosis water. Thin-Film Composite (TFC) membrane unit effectively removes most harmful substances such as heavy metal ions and total dissolved solids from tap water. Employs Standard 10" RO Filters to ease routine replacement of RO filters.

The RO Junior includes 10" Micron, Solid Carbon Block and GAC (Granular Activated Carbon) Cartridges along with a 100 GPD (Gallon Per Day) Membrane.
- Mount the RO Junior to a solid surface using the included Metal Mounting Bracket.
- Attach the included tubing.
- The YELLOW Tubing should attach to the T located on the side of the clear canister.
- The RED Tubing should attach to the T located on the left side of the filter next to the flush valve assembly.
- The BLUE Tubing should attach to the AUTO SHUT OFF valve located behind the membrane housing.
NOTE: All the attachments will require the removal of the Red Tubing Insert used to seal the filter during shipping. When removing the Red Tubing Insert, you will need to remove the blue clip and depress the white-collar ring. This will allow the Red Tubing Insert to be released.
NOTE: When inserting the tubing you must make sure the tubing is inserted completely into the connection, you will notice that the tubing requires a "double" push into the connection to become secure. Replace the blue clip.
- Remove the filters from the protective packaging materials.
- Place the Micron Cartridge in the clear-chambered canister, this way you can view when the cartridge becomes dirty.
- Place the GAC Cartridge in the middle canister.
- Place the Solid Carbon Block in the far left chamber.
- Remove the tubing from the elbow connection on the Membrane Cap. Remove the Membrane Cap and insert the RO Membrane.
Make sure the Membrane is flush with the membrane housing's top. If the Membrane is not inserted completely, the RO unit will not operate correctly.
- Reattach the membrane-housing cap and tubing. Make sure the membrane housing has the O-ring installed prior to replacing the cap. Replace the blue clip.
- Attach the included faucet adapter and connect the yellow tube from the filter to the faucet adapter.
- Verify that the Red and Blue water lines are flowing into the intended location.
- Turn on the water supply, check to make sure the RO unit is operating correctly, and review all connections to make sure they are secure.
Your RO Junior includes a few nice-to-have accessories:
- The unit includes a Pressure Gauge to show the incoming water pressure. Your target pressure is 60-65 PSI. If you are a little low, then you will produce a little less. If you are a little more, then you will produce a little more. Less than 40 PSI you may need to add a booster pump. If it is above 80 PSI, you may want to reduce the water pressure.
- It includes a manual flush valve that will help extend the life of the RO Membrane. Periodically opening the flush valve will allow water to flush past the Membrane where it can remove build up from the Membrane. You can do this for 20-30 seconds each time you operate the RO unit.
- The included Auto Shut Off Valve and Check Valve will work to shut off the supply of water to the Membrane when a shut off device is used on the filtered water line. As the pressure builds up on the blue tubing, the Shut Off Valve will slowly shut off the supply water line and stop water from flowing through the RO Membrane. In addition, you will not be producing wastewater.
- Operating pressure less than 40 PSI may require a booster pump.
- Operating pressure greater than 80 PSI may require a pressure regulator.
- ith initial operation, check for leaks. If a leak is observed, verify that the tubing is pushed into the push-fitting far enough to seal the tubing against the O-ring and that the canisters and caps are sealed properly with their O-rings.
- Many of the components in the RO Junior are plastic and subject to damage by ultraviolet light.
- Never store or operate the unit in direct sunlight or other bright lights.
- Do not store or operate the unit in temperatures above 100°F.
- Do not store or operate the unit in freezing temperatures.
- Do not leave the unit unattended while connected to a water supply.
- Replace the Micron Sediment Filter at least once every 6 months. This will help prolong the Membrane life.
- Replace the Carbon Block Filter at least once every 6 months or when chlorine breakthrough occurs. This will help prolong the Membrane life.
- Operating the RO Junior using softened feed water greatly reduces the chances of Membrane failure.
- Clear canisters have a limited life and should be replaced on an annual basis to prevent possible failure.
The RO Junior uses replaceable Sediment, Carbon Block, GAC and RO Membrane cartridges. The RO Membrane is located in the top horizontal canister.
The RO Junior should only be connected to a cold water supply. The optimal water temperature is 77°F. Using other water temperatures will diminish the effectiveness of the filtration and can accelerate degradation of the membrane. The supply water pressure should range between (40-65 PSI). Water production is determined with a PSI of 60.
Use care not to over tighten the threaded connections: in particular the elbow connections. If the system leaks after installation, use plumber's Teflon® tape on the threaded fittings.
When using a new Carbon Block and/or GAC cartridge, remove the Membrane and run water through the carbon to rinse out any possible carbon dust.
Protect the Membrane from freezing and from drying out. After its first use, the Membrane must never be allowed to dry out. If the reverse osmosis system will not be active for more than 10 -15 days, use a protective solution (Preservation Fluid). The protective solution maintains the efficiency of the osmosis unit by inhibiting bacterial growth and prevents the deposition of impurities.
