Cleaning/Flushing Procedures
Analytical Procedure
PRE-SHIP TEST/PASSIVATE FOR
ORIGINAL EQUIPMENT
MANUFACTURERS
Purpose
If equipment testing is conducted prior to
shipping or storage, new cooling water
systems should be flushed and passivated.
Passivation helps to minimize corrosion and
prepares the metal surface for the corrosion
inhibitors in the treatment program. The
following procedure will passivate
metal surfaces and improve system
performance and reliability.
Procedure
1. Confirm the unit is ready for operation.
2. Fill the cooling water system with
deionized (DI), distilled or Reverse
Osmosis (RO) water and circulate for
several minutes. Repair any leaks before
proceeding.
3. Add the contents of the bottle labeled
460-Thermo100; circulate for 10-15
minutes.
4. Add the contents of the bottle labeled
NALCO 7330; circulate until pre-ship
testing is complete, but no less than a
minimum of 4 hours.
5. Drain the system completely.
6. Attach the Fluid Replacement Reminder
sticker to a prominent location on the unit.
Sign and date the sticker noting when the
system was treated and a scheduled date
for the next treatment.
7. The unit is now ready for shipment or
storage.
