1. Follow the instructions in Section 6.5 to prepare the VNX system for cleaning or
sanitization. Make sure that the cleaning tank drain valve is closed.
2. Fill the tank with the required amount of water.
3. Dissolve required amount of sodium chloride (NaCl) in the tank water.
4. Open the cleaning pump suction valve and bypass valve completely.
5. Divert the product and reject to drain.
6. Start the cleaning pump. When chemicals are well mixed, gradually open the
cleaning pump discharge valve while closing the cleaning pump bypass valve to
adjust the product and reject flow rates to the values given in Section 6.5.
7. Flush the salt solution to drain for about 3 minutes.
8. Turn off the cleaning pump.
9. Drain the tank.
STEP 2: Water Flush To Drain
Water flush rinses the salt solution from the module before cleaning solution is introduced.
