Relative Humidity; Water Quality Recommendations; Prefilter - Thermo Scientific STERI-CYCLE i160 User Manual

Relative humidity:

The heating of the workspace promotes the condensation of the water, thereby ensuring a constant
humidity within the workspace. For continuous operation, a sufficient quantity of processed water
with the recommended water quality must be provided:
• max. fill volume for S

Water quality recommendations:

For trouble-free operation, fill the water reservoir with sterilized distilled water or water treated to an
equivalent quality level. The acceptable conductivity should be within the range of 1 to 20 µS/cm
(resistivity should be within the range of 50 kOhmcm to 1 MOhmcm).
CAUTION Termination of warranty!
Using chlorinated tap water or additives that contain chlorine will void the manufacture warranty.
Similarly, the use of ultrapure water whose conductivity is out of the range of 20 µS/cm and whose
resistivity is out of the range of 50 kOhmcm to 1 MOhmcm will void the manufacture warranty.
If you should have any questions, please contact Technical Support of Thermo Fisher Scientific.
Under normal operating conditions and at the usual incubation temperature of 37 °C, a constant
relative humidity of approx 93% is achieved in the workspace.
If condensation occurs on the culture containers due to high relative humidity, the humidity in the
workspace can be set to a lower level. The relative humidity in the workspace is lowered from approx.
93% to approx. 90%. The modification requires an extended adaption phase. To ensure that it
effectively prevents dew formation on culture containers, it must be used as a permanent setting.
Instructions for activating the Low Humidity function are given in section
page 6-33.

Prefilter

Placed on the front section of the water reservoir cover is a pre-filter. The pre-filter consists of a
dual-layer wire mesh with a silicone frame and is autoclavable as well as heat-resistant. The pre-filter
must remain installed in the device during the Steri-run decontamination routine, but needs to be
removed for refilling the water reservoir.
