Prepare the IT-DS system for chemical cleaning. Follow the instructions in Section 4.2.4.
Make sure the tank drain valve is closed.
Fill the tank with the required amount of water.
Dissolve required amount of sodium chloride (NaCl) in the tank water. Open
the cleaning pump suction valve and bypass valve completely.
Divert the product and reject to drain
Start the cleaning pump. When chemicals are well mixed gradually open the cleaning pump
discharge valve while closing the bypass valve to adjust the product and reject flow rates
to the values given in Section 4.2.3.
Flush the salt solution to drain for about 3 minutes. Turn
off the cleaning pump. Drain the tank.
STEP 2: Water Flush To Drain
Water flush rinses the salt solution from the module before cleaning solution is introduced.
