Water Control - Haier AU082FYCRA(HW) Service Manual

Water control

It is necessary to analyse the quality of water by checking pH, electrical conductivity, ammonia ion content, sulphur
content, and others. The following is the recommended standard water quality.
Item
Standard Quality pH(25°C)
Electrical Conductivity(ms/m) (25°C)
(μS/cm) (25°C) {2}
Chlorine lon (mg CL¯/l)
Sulphur Acid lon (mg SO ¯/l)
The Amount of Acid Consumption
(pH4.8)(mg CaCO3/l)
Total Hardness(mg CaCO3/l)
Calcium Hardness(mg CaCO3/l)
Silica L(mg SO¯/l)
Reference Quality Total iron(mg Fe/l)
Total Copper(mg Cu/l)
Sulphur Ion(mg S2-/l)
Ammonium Ion(mg NH4-/l)
Remaining Chlorine(mg Cl/l)
Floating Carbonic Acid (mg CO2/l)
Index of Stability
NOTE
•The mark "" in the table means the factor concerned with the tendency of corrosion or deposits of scales.
•The value showed in "{}" are for reference only according to the former unit.
