APPENDIX 7 WATER QUALITY
W&H Lisa sterilizers use distilled or demineralized water to generate steam for the sterilization process.
Water quality sensors constantly monitor the quality of the water used for sterilization as water of too high
mineral content can seriously damage the sterilizer and impair the sterilization process.
The total mineral content of water used for sterilization has to be lower than 10 ppm (parts per million) or if
a conductivity meter is used to check the water quality, the conductivity has to be lower than 15 µs/cm.
The table below lists the water quality to be used for steam sterilization (see EN 13060 APPENDIX C).
Contaminants of feed water
Values
Evaporate residue < 10 mg/l
Silicon oxide, SiO
2
< 1 mg/l
Iron < 0,2 mg/l
Cadmium < 0,005 mg/l
Lead < 0,05 mg/l
Rest of heavy metals, excluding iron, cadmium, lead < 0,1 mg/l
Chloride < 2 mg/l
Phosphate < 0,5 mg/l
Conductivity (at 20°C) < 15 µs/cm
pH value 5 - 7
Appearance colorless, clean, without sediment
Hardness < 0,02 mmol/l
If the sterilizer generates a display message in regards to poor water quality, check the water source (refer
to the water treatment system user manual; replace resin cartridge etc.). In case distilled or demineralized
water is purchased from the market, switch to a brand of better quality.
The use of water with a conductivity greater than 15µS/cm may affect the steriliza-
tion process and damage the sterilizer (EN 13060). A conductivity greater than
50µS/cm may strongly affect the sterilization process and seriously damage the
sterilizer.
The use of water for steam generation with contaminants at levels exceeding those
listed in the table above, can greatly shorten the working life of the sterilizer and
void the manufacturer's warranty.
