8.
Add a small amount of silicone grease to the tank threads and screw on 7500 control valve
carefully. Do not use pipe‐joint compound, vegetable oil, Teflon tape, or Vaseline or other
petroleum greases to lubricate tank threads.
9.
DO NOT USE VEGETABLE OIL OR PETROLEUM GREASE ON ANY PART OF THE 7500 CONTROL
VALVE. O‐rings are OK to lubricate but not the main tank threads.
10.
Connect some flexible tubing from the drain connection on the 7500 control valve to a suitable
drain such as a septic tank or drain to a sewer. It is OK to run the drain line up and over the 7500
Neutralizer up to 4 feet above the top of the tank. If the drain line will be more than 20 feet, use
larger diameter tubing such as ¾” or 1”.
11.
Note that it is desirable to be able to run the drain line into a bucket in order to test the
backwash flow rate in the future. This is why hard piping the drain line is discouraged: however,
if you do use hard PVC piping for the drain line, and you are able to remove the hard PVC drain
piping and attach flexible tubing should you ever desire for testing purposes, it is OK to use rigid
PVC pipe for the drain. Make sure the drain tubing is firmly clamped to the barbed fitting with a
hose clamp to prevent leaks.
Programming Your Valve and Setting Time and Days for Backwash
Next, you will need to program the system to work as a Neutralizer Filter. There are a few settings
that must be changed before the system can be put into service. Plug in the control valve and begin
the programming instructions.
