Compliance with the above data should be tested in accordance with acknowledged
analytical methods, by an authorized laboratory.
Attention:
The use of water for autoclaves that do not comply with the table above may have
severe impact on the working life of the sterilizer and can invalidate the
manufacturer’s guarantee.
Tap Water supply
Maximum hardness value 0.7-2.0 mmol/l
Note:
The use of soft water is strictly forbidden!
Please consult a water specialist!
