Quality of cooling water
Distilled water causes immediate corrosion on bare parts, which is often unno-
ticeable at first, but later leads to serious corrosion damage.
Ü
Do not use pure or distilled water.
Deposits in cooling channels due to unsuitable cooling water prevent the dis-
sipation of heat.
Ü
Use cooling water with the following properties:
Drinking water
Hardness
PH value
Additive (corrosion protection)
