HYDRAULIC SCHEME FOR SHUTDOWN PROCEDURE

FIG. 6-1

NOTE

The available products for the shutdown procedure are the following:
1) SCHENKER CLANING 1 (SC1

– Acid product) to remove the inorganic components and preserve the

watermaker during winter break
2) SCHENKER CLEANING 2 (SC2

– Alkaline product) to remove the organic components (mould and

bacteria) when already deposited; in this case the system becomes stinky.

NOTE

Normally only SC1 is required, but in case of strong smell it is recommended to use also the SC2.
The sequence in this case will be SC2 first, then a washing of the system. Finally the SC1.
It is advisable to replace the filters after performing shutdown procedure with new ones.
