7.3.1.3 Cleaning the Liquid System
Cleaning the
Liquid System
To prevent growth of micro-organisms in the liquid system, we recommend
cleaning the liquid system once a week. Depending on your application you can
fill the system with one of the following agents (water is used as system liquid):
Mild detergent
Weak acid and base in sequence
Disinfectant
Note:
If a system liquid other than de-ionized water is used, clarify the suitability
of the cleaning agents with the manufacturer.
To fill the liquid system and allow the agent to react, proceed as follows:
1
Place the tubing in a bottle with the cleaning agent and flush the liquid system
twice.
Refer to cross references above.
2
Allow the cleaning agent to react for at least 10 minutes.
3
Place the tubing in a bottle with distilled or de-ionized water and flush the
liquid system twice.
Refer to cross references above.
4
Flush the liquid system eight times with system liquid.
Refer to cross references above.
