For Automatic Backwash Filters With Dome Hole
1. Check the media height by shining a flashlight through the tank to see
the height of the mineral. If the level is not visible, the top fill plug will have to be
removed (if available) to measure the height. The media tank should only be two-
thirds full (see diagram). Proceed to step 2.
2. To remove top fill plug, turn off the source of the water and open a conditioned
water tap to relieve the water pressure on the system. Place unit into the bypass
mode. Unscrew the top fill plug.
Caution: Never unscrew top fill plug unless pressure is fully released from
system. Serious injury and/or flooding can occur.
3. Siphon out some water from the tank through the dome hole. This will allow room
when adding the media.
4. Add the appropriate amount of replacement media through the dome hole (top fill
plug). Make sure you add the correct amount and type of media (calcite or calcite/
corosex mix). If needed, siphon out more water as the media will displace the water
inside the tank. Pay close attention to media level when filling (see diagram).
Do not overfill.
The additional media added should not be higher than two-thirds
of the tank height when measuring from the bottom (see diagram). Once the right
height has been achieved, replace top fill plug. Grease “O” ring if necessary using
only silicone grease.
Do not use petroleum based grease such as Vaseline.
Tighten appropriately.
5. Leaving controller in the bypass position, turn on water source and refer to the
start-up instructions of the controller and complete the procedure.
6. Once start up is complete, please check the top fill plug for any leaking.

Acid Neutralizers raise the pH of mildly acidic water. The raising of pH utilizes a sacrificial mineral that will need replenishment every 6 to
12 months. Typically the media should not be below the halfway point in the tank. In order to check the mineral height and before adding
mineral to the system, please follow these instructions.
