3. A bottle of powder
SCHENKER CLEANING 1 (SC1)
. The solution must be prepared following the

HYDRAULIC SCHEME FOR SHUTDOWN PROCEDURE
FIG. 6-1
NOTE
The available products for the shutdown procedure are the followings:
1) SCHENKER CLEANING 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 and/or the water produce
a “bad eggs”
smell. Allow a period of 20 mins for both acid & alkaline cleaning.
It is important that the depressurizing valve is partially open when this procedure is carried out.
NOTE
Normally only SC1 is required, but in case of strong bad smell (organic contamination) it is
recommended to use SC2 as well.
The sequence in this case will be SC2 first, then a flushing of the unit with fresh water, and finally the
SC1. Leave the product in the system to winterize the unit.
It is advisable to replace the filters after performed the cleaning procedure with new ones.
If the unit will not be used for a long period of time (for example before winter) the filters can also be
removed.
