Step 2: Install the new aerator. See Fig. 1.

Step 3: Remove and discard the protective cap. While holding down the white lock-ring on the unit, place the top over the end of the new aerator. Release the lock-ring. The unit will clamp into place. See Fig. 2. A slight downward tug on the entire assembly will confirm the connection.

Step 4: Remove the small protective cap from the stainless steel tube near the top of the unit and attach the plastic tubing as shown in Fig. 3. Fresh water will drip from this tube. Collect it by directing the tube into a pitcher or other container. Place the container in the sink to catch any overflow. Fig 4.

Operation
Slowly turn on the cold water. Tap water will circulate through the unit. Concentrated salts and impurities exit in a steady stream from the small outlet at the bottom of the unit. Allow this water to go to the drain. For the WaterMaker Mini to work properly, water should be produced in 0.5 gallon (2 liter) volumes or more.

Important Product Information

1. Use cool water only.
2. First Use - Allow the unit to run for 4 hours before collecting any drinking water. This will allow carbon dust and residue from the sanitizing agent to be rinsed from the unit.
3. Store the WaterMaker Mini in the refrigerator. Do not allow the unit to freeze.
4. This reverse osmosis system contains a replaceable treatment component critical for effective reduction of total dissolved solids. The product water should be tested periodically to verify that the system is performing satisfactorily. With normal use and care, the membrane in this unit will last one year. In order to determine when your unit requires maintenance, Nimbus recommends testing the product water every six months.

Storage
Turn off the cold water. Allow the unit to drain for 30 seconds. Depress the white lock-ring and lower the unit away from the faucet. Place the unit in a plastic zipper-lock bag and store it in the refrigerator until next use. Do not allow the unit to freeze.

Troubleshooting
Normal fresh water flow is a drip process. Normal wastewater flow is a steady stream, both may be impaired by a high volume of particulate matter in your tap water.

If your unit develops a leak, check the following:

1. If the unit leaks between the replacement aerator and the quick-connect lock-ring, a poor seal may be the cause. Lubricate the circular black ring in the quick-connect portion of the unit with a very small amount of petroleum jelly.
2. If a leak occurs between the quick-connect and the cap at the top of the plastic pressure vessel, first check to see that the mesh screen located in the cap is properly seated, then hand-tighten the cap and pressure vessel.

Maintenance Schedule
The Water Maker Mini membrane must be replaced on a regular basis to maintain efficiency and to safeguard water quality. For more accurate membrane filter replacement intervals, the system should be tested for TDS every six months. A TDS meter and replacement parts are available from Nimbus Water Systems or authorized Nimbus dealers.
