1. Check the media height by shining a flashlight through the tank to see the height of the mineral. If the level is not seen,
the top fill plug will have to be removed (if available) to measure the height. 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 calcite (replacement media) through the dome hole. If needed, siphon out more
water as the media will displace the water inside the tank. Pay close attention to media level when filling.
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.
The IACG Iron Filter/Acid Neutralizer will remove iron and also 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.
