 CIP CLEANING INSTRUCTIONS
NOTES:
 Choose a cleaning product appropriate for the materials used in the system that will
come into contact with the cleaner. Follow all manufacturer’s instructions when
using any cleaning agent.
1) Isolate the heat exchanger from the system and connect the CIP unit to the heat
exchanger with the flow direction opposite to normal operation.
2) Dilute and mix the cleaning agent with the CIP tank water according to the manufacturer’s
instructions, and heat to the required temperature.
3) The cleaning agent should be circulated through the system at the fastest flow rate
available (10% to 20% above normal), but at the least should be at the normal operational
flow rate.
4) Circulate the cleaning solution for at least 30 minutes and up to 4 to 6 hours. If possible,
reverse the flow direction every 30 minutes.
5) After the cleaning interval, always rinse the system thoroughly with fresh water. Circulate
fresh water through the system for at least 10 minutes after the cleaning operation. A
solution of
1-2% sodium hydroxide (NaOH) or sodium bicarbonate (NaHCO3)
before the
final rinse ensures that all acid is neutralized.
6) Disconnect the CIP unit from the heat exchanger.
7) Check the performance of the water heater against the data provided in the equipment
manifest, such as the pressure drop data. Compare to pre-cleaning results. Noted
performance differences can be used to trigger future maintenance.
8) Responsibly dispose of used cleaning chemicals.
