Cloudy water is a sign that the PF-2 Fluoride Filters need additional priming. The cloudiness is caused by residual process dust within the capsule of the filter. Please continue with the following instruction. The priming process may need to be repeated more than once to completely remove any residual manufacturing dust.
1. Plug one end of the fluoride filters with the blue caps they come with initially. If you do not have the blue caps, your thumb will do.
2. From the uncovered end, fill the capsule part way with water and cap/plug both ends.
3. Moderately shake the filters to loosen any residual process dust that may be trapped within the filter. Gently tapping the PF-2 element on the counter a few times will also help to loosen any excess manufacturing dust.
4. Remove both blue caps from the ends of the PF-2 element and empty out any residual water.
5. Next, re-prime the filters following standard procedure.
a. Place the rubber priming button (tan colored) onto one end of a PF-2 and align the hole of the filter with the hole of the rubber washer.
b. Press the priming button up against the sink faucet so that the priming button creates a seal between the faucet and the PF-2 element. Place thumb on top of the faucet to apply pressure, this creates a better seal.
c. Turn on the cold water slowly, allowing water to fill the cavity of the filter and discharge from the opposite end. Allow water to flow for one to two minutes or until water runs clear, whichever is longer.
d. Turn the Pf-2 filter over and prime the opposite end (reversing the flow of water) repeating steps a. thru c. until water runs clear from both directions.
e. To determine if more priming is necessary, run additional water through the element and using a clear glass, collect the water discharging from the opposite end. If the collected water still appears cloudy, continue priming until the water is clear.
Note: Do not immediately discard the priming button or blue caps as you may need them in the future to re-prime the elements.
