7500-C Greensand Filter Installation & Startup Guide
Pre-Installation:
1. Review your packing list and make sure you have received all the parts before beginning
installation.
2. If you are going to be turning off the water to the house and you have an electric water heater,
shut off the power to the water heater before beginning installation in case water heater is
accidentally drained.
3. Pick a suitable location for your filter system on a dry level spot where it won't be exposed to
freezing temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation, and make sure you have
received all of your packages before beginning or scheduling an installation. Installation typically
takes 3 to 5 hours. However, after installation the Greensand Filter must be allowed to run
through a complete backwash and rinse cycle.
5. After the system is installed and running, your water may be discolored, or full of Pro‐OX or rust,
particularly if this is older or corroded piping. This typically clears up over a day or two.
