Subject
Water Analysis Kits
Model
Whole Dishwashing range
Problem
Stainless steel gets rusty, higher energy consumption due to scale, poor
washing/rinsing performances, etc.
Reason
The quality of water is not suitable for DW machines, i.e. the quantity of
chlorides is high (more than 20 ppm) and/or the water is hard (more than 8°dH
/ 14°fH) and/or the electrical conductivity is high (more than 400 μS/cm) etc.
Action in
Factory
There are 3 kits available for water analysis as follow:
• CHLORIDE test kit 0S0585 (approx. 200 tests);
• HARDNESS test kit 0S0586
(approx. 300 tests);
• A handy suitcase 0S0483 containing 0S0585, 0S0586, a conductivity/pH
meter 0S0481

Field
Remember that water is one of the most dangerous element since it may
contain contaminants.
Drinkable water could be harmful to the appliances because of the chloride so
it does not represent any “security”
Always check chlorides, hardness and electrical conductivity
before installing any appliance!!!
