Anti-Scalant Filling and Settings
If anti-scalant is used in lieu of a water softener to control hardness, the dose and mix is determined using the feed water analysis, the chemical pump specifications and the RO system operating parameters. The table below can be used in 90% of the applications. However, in some rare cases, the US Water Systems Specialist will have specific guide- lines. If this is the case, the US Water Specialist will make it known. Use the following procedure when filling the tank:
1
Fill the tank with 5 gallons of clean water (preferably RO water)
Add specified oz of the Hyper-Guard Plus 7000 anti-scalant solution for each gallon of water to the tank using the table provided.
2
Use a measuring cup to collect the proper anti-scalant concentrate. Use the table to determine the proper mixture.

Defender 3 GPD Injection Pump
Or
5 GPD Injection Pump, 15 Gallon Tank. Set pump to "5" (50%).
Stir tank weekly.
3
Make sure the toggle switch on the injection pump is in the "ON" position
4
Plug the Injection Pump into the Chemical Pump power cord on the RO system.
5
The anti-scalant pump will operate when the RO is running
This pump should self prime during the start up procedure. The solution tank can be topped off with 10 more gallons of mixed solution once the RO system is online. Be sure to mix the solution correctly when topping off the solution tank. Future tank fills can be done using the RO water produced by the new RO system.
NOTE: it is a good practice to mix the anti-scalant solution weekly to ensure the solution concentration stays consistent.
