7500-M Neutralizer Installation & Startup Guide
Initial Backwash
1 After programming, the system must be run through an initial backwash.
2 Close inlet ball valve and outlet ball valve and open the bypass valve.
3 Press the Manual/Return button to enter the backwashing cycle. When the backwash icon
is displayed, slowly open the inlet valve B to a quarter position to make the water flow into
the resin tank; you should be able to hear air escaping from the drain pipeline.
4 After all the air is out of the pipeline, open inlet valve B and clean the foreign materials in
the tank until the water is clean.
5 If possible verify that the backwash flow corresponds with the size of your system below.
You can easily run the drain hose to a bucket and using a watch verify the flow rate in
gallons per minute. An adequate backwash is critical to properly clean the Calcite media and
prevent it from cementing together.
6 After the backwash, the system will automatically go into the fast rinse stage. Both stages
will last as long as you have programmed the valve for. The control valve will return to
service status (indicated by the up flowing meter on the left) after the backwash and rinse
are complete.
7 Repeat the Regeneration (backwash and rapid rinse cycle) step 3‐4 more times until you see
clear water through the drain line or your hose bib. Once you have tested your PH at the
hose bib and it is within range, You Can open up the outlet valve to your house.
Congratulations, you are done setting up your valve!
