1. Charge system with 10 % by volume of AC101.
2. Cold Passivation : Circulate for 1 hours at ambient to 65oC if within equipment manufacturer's temperature limitations or Soak for 2 hours if the system cannot circulate .
Hot Passivation : Circulate for 30- 45 minutes at 70-80oC if within equipment manufacturer's temperature limitations or Soak for 1 hours if the system cannot circulate
3. Flush the degreasing solution to drain (or store in a special container for next vessel, if any).
4. (a) Execute 10 burst rinses.
(b) Test last burst rinse for absence of foaming and neutrality by
determining that pH or titration matches with pH of the fresh water
(7 – 8)
(c) Execute additional burst rinses as needed to match pH of tap water and/or elimination of foam in the rinse water.
5. Allow 10 minutes drainage time and inspect for good water sheeting action. If water beading is observed repeat cleaning procedure.
