Assembly and Installation Instructions:
1.
Wrap the top of distributor tube with electrical or duct tape so that no gravel or Carbon media will
go down the distributor tube when adding the media.
2.
Add the filter gravel that came with your order. You want the gravel to cover the bottom
distributor screen before adding the Carbon media.
3.
Next add Carbon media. The tank should be about 2/3rds full of media, do not fill more than
2/3rds, even if there is some media left over.
4.
Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when
removing cap or tape.
5.
Fill tank completely with water. This will allow the Carbon Filter media to settle and reduce the
need of purging the air out of the tank later.
6.
Add a small amount of silicone grease to the inner O-ring, where the distribution tube goes. Next,
install the top screen (This is a funnel-shaped plastic screen that locks into the control valve and
prevents resin from being backwashed out to drain during the regeneration cycles.). Now,
lubricate the main tank O-ring and screw on 7500 control valve carefully. Do not use pipe-joint
compound, vegetable oil, Teflon tape, or Vaseline or other petroleum greases to lubricate tank
threads.
