Device Environmental Information
The peak sound level generated by the autoclave is 67dBa with background noise
of 48dBa during sterilization stage, and 65dBa during drying stage.
The total heat per hour transmitted by the autoclave is <200Wh.
Requirements with concern to Water Quality
The distilled or mineral-free water supply to the autoclave shall be according to
the table below:

Water Quality
Compliance with the above data should be tested in accordance with
acknowledged analytical methods, by an authorized laboratory.
Caution:
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.
Use only deionized water, having a maximum conductivity of 15 µs/cm.
Conductivity greater than 15 µs/cm may cause failures.
