How to Prime Fluoride Filters with Priming Button Priming with the thick tan washer, referred to as the priming button is the strategy for priming Fluoride Filters. A priming button is incorporated with every Fluoride Filter purchase. 1. With the blue caps in position wash the exterior of each fluoride filter out elements with water and mild dishwashing soap, then rinse. 2. With clear hands, get rid of either blue caps from every single finish of either filter out elements. 3. Place the rubber priming button (tan colored) onto one finish of a fluoride filter and align the opening of the clear out with the opening of the rubber washer. 4. Press the priming button up against the sink tap simply so the priming button creates a seal between the tap and the Fluoride Filter. Place your thumb on height of the faucet to use pressure, to create a better seal (as considered in picture). 5. While retaining the priming button against the faucet, activate the bloodless water slowly, permitting water to fill the cavity of the filter and stream from the choice end. 6. Allow water to move for at the very least 30 seconds or till water runs clear. 7. Turn the Fluoride filter out over and top the opposite end (reversing the movement of water) repeating steps 3-5 till water runs clean from either directions. 8. To decide if the filter is purely primed, assemble the filtered water in a clear glass and hold it as much as the mild to appear if all of the cloudiness is long past from the water, if now not proceed priming until water is clear. 9. This clear out is now primed and able to install. 10. Repeat priming steps 1-7 for every further Fluoride Filter. note: Different manufacturing unit batches can have various look labels, that will now not impact the use of the product Material: activated carbon colour: As proven Package Contents: 2 x Water Filter Only the above kit content, different products should not included.
