7500-Rev2.5 Greensand Filter Installation & Startup Guide

Filter Tank Assembly and Installation Instructions:

1. Wrap the top of distributor tube with electrical or duct tape so that no gravel
or Greensand 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 Greensand media.
3. Next add Greensand 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.
5. A 1 cup of Clorox or other chlorine bleach and fill tank completely with water. This will allow the
Greensand Backwash Filter media to settle and reduce the need of purging the air out of the tank
later. Allow Greensand to soak for at least 1 hour but 24 hours or more is OK.
6. Add a small amount of silicone grease to the
inner O‐ring, where the distribution tube goes.
7. Next, install the top screen by inserting upwards
and rotating to lock in place. (This is a funnel‐
shaped plastic screen that locks into the bottom
side of control valve.
8. Lubricate the main tank O‐ring with silicone grease and
screw on the 7500‐Rev2.5 control valve carefully. Do
not use pipe‐joint compound, vegetable oil, Teflon
tape, or Vaseline or other greases to lubricate tank
threads.
9. Connect bypass assembly with 1" pipe connectors to
control valve install black clips and make sure valve is in
bypass position.
10. Insert meter cable into meter cable port on bypass.
11. Install inlet and outlet piping and hook up drain line tubing to drain.
12. If you are in earthquake zone, strap your backwash filter tank to wall with metal strapping.
13. Proceed to programming your 7500‐Rev2.5 control valve timer and backwash frequency.
