02.3.3 Treatment
When changing the additive or when entering an additive into a system
where untreated water has been used, the complete system must be
cleaned (chemically) and rinsed before fresh treated water is poured
into the system. If, against our recommendations, an emulsion oil has
been used, the complete system must be absolutely cleaned of oil and
greasy deposits.
Evaporated water should be compensated by untreated water;
if treated water is used the content of additives may gradually
become too high. To compensate for leakage or other losses, add
treated water.
In connection with maintenance work calling for drainage of the
water system, take care of and reuse the treated water.
The list of approved cooling water additives and treatment sys-
tems can be found in the end of this chapter.
Note! Ask the supplier of the treatment product for instructions about
treatment procedure, dosage and concentration control.
Most suppliers will provide a test kit for the concentration control.
Additionally a frequent laboratory analysis of cooling water at 3 months
interval is recommended to ensure safe engine operation.

Injection water (DWI-engines)
02.4.1 Water quality
Water used for Direct Water Injection (DWI) has to fulfill the following
requirements:
Requirements for DWI-water
pH
5-9
Total Hardness
max. 10
°dH
Chlorides
max. 80
mg/l
Suspended Solids
max. 50
mg/l
Silicon
max. 50
mg/l

max. 50
°C
Fresh water to be used, see also section 02.3.1.
The water must not be contaminated by oil, grease, surfactants or
similar impurities. These kind of impurities may cause blocking of the
filters or other malfunctions in the direct water injection system.
