7500-REV4 Sediment Backwash Filter Guide

Tank Assembly and Installation Instructions:

1. Wrap the top of distributor tube with electrical or duct tape so that no gravel
or Turbidex media will go down the distributor tube when adding the media.
2. Make sure you "test fit" distributor tube, find divot that keeps tube
centered, before adding gravel so distributor tube does not extend past
top of tank.
3. Add all the filter gravel that came with your order.
4. Next add Turbidex 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.
5. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube.
6. Fill tank completely with water. This will allow the Sediment Backwash Filter media to settle and
reduce the need of purging the air out of the tank later. Allow Turbidex to soak for at least 1 hour
but 24 hours or more is OK. Turbidex contains trapped air will help clear this out.
7. Add a small amount of silicone grease to the inner O‐ring, where distributor tube goes.
NOTE: Your Sediment Backwash filter does not use a top screen. If you are looking for a
8.
top screen, there isn't one provided, it is not needed or recommended.
9. Lubricate the main tank O‐ring and screw on the 7500‐Rev4 control valve carefully. Do not use
pipe‐joint compound, vegetable oil, Teflon tape, or Vaseline or other petroleum greases to
lubricate tank threads.
10. Connect bypass assembly with 1" pipe connectors to
control valve, making sure Inlet and Outlet is correct.
