Refer to your Fleck 7000 service manual for more information about how your control valve is
programmed if desired.
Maintaining Your Neutralizer 7000 Filter System
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 if you are using a blend.
3.
For most residential applications, adding Calcite media once or twice a year is adequate. Do not fill
more than 3/4ths full; about 2/3rds full is best.
How to Add Calcite Media to the Fleck 7000 Neutralizer Filter
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 before the
neutralizer.
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 of the neutralizer tank.
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. If water on the floor is OK, then you do not have to
siphon water out first before pouring Calcite media into the fill plug hole.
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. You can lubricate the threads with some vegetable oil or silicone grease,
but do not use Teflon tape or plumbing grease.
7.
Plug the control valve back in and press the Extra Cycle button so the Fleck 7000 control is in a
backwash cycle.
8.
Turn on the bypass valve - slowly at first - back to the service position (if it is in "service" this means it
is in the proper position for filtering and neutralizing).
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.
