Adding Anti-Scale Media

PROCEDURE FOR ADDING ANTI-SCALE

MEDIA

1. Remove the top cover as described on page 6.

2. Bypass the system by turning both bypass handles

perpendicular to the flow of water (See Fig. 8).

3. Slowly loosen the installation collars between the

bypass valve and in/out head (See Fig. 9), allowing

pressure to escape from system.

4. When both installation collars between bypass and

in/out head are completely loosened from the in/out

head, pull the system away from the bypass valve.

5. Holding the tank neck adapter with a strap wrench,

unscrew the in/out head from the tank neck

adapter (See Fig. 10). Once the in/out head is

completely unscrewed, check to see whether the

riser pipe (See Fig. 10) is still inserted in the in/out

head. Remove it by lifting the in/out head enough

to grasp the riser pipe and pull it free from the

head.

6. Using a hose or tube that is 3/4" (1.9 cm) O.D. or

less, siphon the water from the mineral tank

through the riser pipe. This will keep the top-

bedding HDPE from floating out of the tank as the

water rises when adding media.

7. Remove clips and clamps (See Fig. 11), and lift

tank neck adaptor and top distributor from the tank

neck. Be sure not to lose the o-rings.

8. Plug, cap or tape the open top of the riser pipe

(See Fig. 11) to keep media from entering the riser

pipe.

IMPORTANT: Media entering the riser pipe will

restrict fow and increase system

pressure drop significantly.

9. Use a funnel that either fits around the riser pipe or

alongside of it and fits inside of the tank neck.

10. Add anti-scale media to the tank. Systems are

shipped from the factory with 3 lbs. (1.36 kg) of

media. Replacement media is supplied in 1.5 lb.

(0.68 kg) containers (P/N 7353755).

11. Uncover the riser pipe and reassemble the

system in reverse order, making sure that all

o-rings are in place.

NOTE: The riser pipe (See Fig. 10) may have been

pulled up from the bottom of the mineral tank.

If this has happened, the in/out head may not

engage the threads of the neck adapter. To

correct this, apply air or water pressure to the

riser pipe. This will move the media at the

bottom of the tank, allowing the riser pipe to

be lowered to the bottom of the mineral tank.
