5900e Greensand Filter Installation & Startup Guide
1. Wrap the top of distributor tube with black electrical tape or blue painter's masking tape so that
no gravel or Greensand media will go down the distributor tube when adding the media. Leave
a folded tab of tape that you will be able to grab onto to gently pull off the tape after filling the
tank. When you are ready to screw the valve head on, apply silicone lubricant to the outside of
the distribution tube, and the O-ring on the control valve where the tube goes in.
2. Add the filter gravel that came with your order. You want the gravel to cover the bottom
distributor screen before adding the Greensand media.
3.
Next add Greensand media. The tank should be about 2/3rds full of media
Do not fill past 2/3rds, even if there is some extra media left over.
4. Remove tape from top of distributor tube. Be careful not to pull up distributor tube when
removing tape.
5. Fill tank completely with water. This will allow the Greensand Filter media to settle and reduce
the need of purging the air out of the tank later.
6. Attach plastic top screen to the under-side of the 5900e control valve. It is a funnel-shaped
plastic screen that snaps on to the control valve and prevents media from being backwashed out
to drain during the regeneration cycles.
