How to Replace the Pro-OX Filter Media
1.
Typically, after 3 to 5 years the Pro-OX media will start to allow a small amount of free-
chlorine to flow through the Pro-OX media. To accomplish this:
2.
Turn water to system and depressurize the filter by opening a hose bib or faucet after
the Pro-OX backwash filter system.
3.
Put system on bypass and remove the union fittings between the bypass valve and the
5900-BT control valve.
4.
Unscrew the control valve and set aside.
5.
Siphon water out of the Pro-OX filter by inserting a small flexible tube down the
distributor tube and siphoning out the water.
6.
Lay down clean tarp outside or somewhere you can flush water and clean the tank out.
7.
Insert a garden hose in the tank and allow water to flow down center distributor tube.
Pro-OX media will begin to flow out on to the tarp.
8.
Flush out all Pro-OX media and gravel and discard to landfill or trash.
9.
Rinse out filter tank until clean.
10.
Add a ½ cup of household bleach and a few gallons of water and rinse inside of tank.
11.
Rinse out filter tank until chlorine is gone.
12.
Add gravel and new activated Pro-OX and re-start up system following original
directions in this manual.
