7800 Greensand Filter Installation & Startup Guide
Assembly and Installation Instructions
1. By hand, unscrew the entire 7800 control valve from top of tank if it was shipped screwed on.
Place distributor tube in tank if not already inside. If not already done, make sure the blue cap is
on top of distributor tube, or wrap the top of distributor tube with electrical or duct tape. You
do not want gravel or Greensand to go down the distributor tube.
Plug or tape top of distributor tube
when adding media to prevent media
from entering. Remove when
finished.
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 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. If possible at this point, fill tank completely with water. This will allow the Greensand Filter
media to settle and eliminate the need of "purging" the air out of the tank later.
6. Attach plastic top screen to the under-side of the 7800 control valve. It is a funnel-shaped
plastic screen that snaps on to the control valve and prevents resin from being backwashed out
to drain during the regeneration cycles.
