PF-2 Fluoride and Arsenic Reduction Elements
Priming Tips
1. With the blue caps in place, wash the exterior of each PF-2
element with water and dishwashing soap.
2. With clean hands, remove one blue cap from the end of a PF-2
element. It does not matter which blue cap is removed.
3. While holding the PF-2 element under your sink faucet,
slowly turn on the cold water and fill the PF-2 element with
water (about ½ cup is needed). Then turn off the water.
4. Replace the blue cap on the PF-2 element and shake it vigorously
to help loosen any manufacturing dust that may be trapped within
the element. Gently tapping the PF-2 element on the counter a few
times will also help to loosen any excess manufacturing dust.
5. Remove both blue caps from the ends of the PF-2 element and
empty out any residual water.
6. Place the tan rubber priming button onto one end of the PF-2
element and align the hole of the element with the hole of the
priming button.
7. Press the priming button up against the sink faucet so the priming
button creates a seal between the faucet and the PF-2
element. Place your thumb on top of the faucet to apply more
pressure, creating a better seal.
8. Turn on the cold water slowly, allowing water to fill the cavity
of the PF-2 element and discharge from the opposite end.
Allow water to flow for one to two minutes or
until the water
runs clear.
9. 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.
The priming process may need to be repeated more
than once to completely remove any residual manufacturing
dust.
10. Turn the PF-2 element over to prime the other end, repeating
steps 6 through 9.
11. Repeat steps 2 through 10 for each additional PF-2 element.
Note:
Do not discard the priming button or blue caps as you may need
them in the future to re-prime the elements.
chambers can also be cleaned in the dishwasher but remove all parts and
attachments first. If you have a Berkey Light system, do not place any of
its components in the dishwasher.
Note
:
If your Berkey system is filtering hard water, which is water with a
high dissolved mineral content, scale from naturally-occurring minerals
such as calcium may develop in the spigot and chambers after prolonged
use. These deposits can be removed by soaking the affected components in
a 50-50% vinegar and water mixture for about 15 minutes. Then wash
with water and mild dish soap. Do not soak the Black Berkey Elements or
optional PF-2 elements in the vinegar mixture.
Frequently Asked Questions (FAQS)
Why does my Berkey system leak where the upper and lower cham-
bers fit together?
• There is no water-tight seal between the upper and lower
chambers of the system because this type of seal would
prevent gravity filtration. Therefore water will leak from
where the two chambers fit together if both the upper and
lower chambers are full or nearly full of water. To prevent
overflow, it is recommended to empty the lower chamber
completely prior to refilling the upper chamber.
•
If at any time you experie nce an issue with your system
leaking water, discontinue use, empty the water from both the
upper and lower chambers, and contact Customer Service.
Why Does the Upper Chamber Still Contain Water After the Filtering
Process?
• The Berkey systems are gravity filters and as the water level
in the upper chamber decreases the filtering process will
naturally slow down because there is less water pressure
available to force water through the elements. It is normal for
one to two inches of water to remain in the upper chamber.
