Maintaining Your Neutralizer
1.
Check the pH before and after the neutralizer. You want to have a pH of at least 7.0
after the neutralizer filter.
2.
If the pH drops below 7, check the depth of the Calcite media by shining a bright light
through the tank. Your tank should be about 2/3rds full of media. When the media
level drops to ½ full, it is time to add more Calcite or Calcite blend media .
3.
For most residential applications, adding Calcite media once or twice a year is adequate.
Do not fill more than 2/3rds full.
How to Add Calcite Media
CALCITE MEDIA CONTAINS DUST. USE PAPER MASK OR VENTILATE TO AVOID BREATHING DUST.
1.
Begin by putting the neutralizer filter on bypass or turning the water pressure off.
2.
Initiate a manual backwash cycle. Since it is on bypass, this will relieve the pressure
inside the control valve, so you safely unscrew the Media Fill Plug located on top.
3.
Unplug the control valve cord from the wall outlet.
4.
Unscrew the media fill plug with channel locks or pliers and using a tube or hose siphon
2 to 3 gallons of water out of the filter tank. If you don't siphon water out before
adding filter media, water will flow out the fill plug hole and onto the floor.
5.
Add neutralizer filter media until the tank is 2/3rds full. Do not over‐fill; be sure to leave
at least 12" of free space above the media to allow room for it to expand during a
backwash.
6.
Put the top fill plug back in. Do not use Teflon tape or plumbing grease, it is an O‐ring
seal.
7.
Plug the control valve back in. The control valve is in the backwash cycle.
8.
Turn on the bypass valve ‐ slowly at first ‐ back to full open.
9.
Allow the system to go through a complete backwash and rinse cycle. Repeat this
backwash and rinse cycle by starting another manual cycle, so the neutralizer is
thoroughly backwashed and rinsed before going back into service.
