Original Instructions
2. Prepare approximately 16 liters of ONE of the following solutions:
0.3% Bleach (1 liter 5.25% household bleach in 15 liters of clean water)
OR
2.0% Formaldehyde
OR
3.0% Hydrogen Peroxide
3. Fill each bowl approximately ½ full with sanitizing solution and reattach them to the unit.
Connect a temporary feedwater line to inlet port of the WaterPro PS (Item 1, page 12 of this
manual) and place it in the container of sanitizing solution.
4. Place a suitable container under the dispense valve or gun, turn on unit and allow to operate
until a steady stream of sanitizing solution flows from the valve or gun.
5. Close the valve or gun and allow the WaterPro PS to recirculate the sanitizer for at least two
hours, periodically opening the dispense valve or gun to sanitize it. After the sanitization is
complete, unplug the unit and open the dispense valve to depressurize the system.
6. Carefully discard the sanitizing solution, WITHOUT RINSING OUT THE BOWLS.
7. Install new cartridge in the appropriate bowls, plug in and turn on the WaterPro PS.
8. Leave the dispense valve open until approximately 10 liters have been dispensed, then close
the valve and install a new final filter on the dispenser, if required. Allow the unit to recirculate
until the resistivity is acceptable. The unit is now ready for operation.
