S41i CO2 Incubator Shaker — Operating manual
 Remember to reset the CO
2
setpoint to the desired level after sampling.
We also recommend that you Auto-Zero the CO
2
system at least once every month to ensure that
CO
2
level is correct (see Monthly check on p. 62).
6.2 Cleaning
1. Routinely clean the exterior of the incubator/shaker by wiping it over with a soft cloth,
moistened with soapy water.
2. Rinse the soap from the cloth in clean water, and wipe the exterior surfaces again.
6.3 Disinfection/Decontamination
The recommended disinfecting agent for use with the incubator/shaker is a solution of 70 %
isopropanol (isopropyl alcohol) and 30 % distilled water.
Be sure to follow appropriate safety regulations while you are using this solution. To best protect
yourself, your incubator/shaker and your work area, follow these instructions:
1. Program 0.0 % CO
2
and switch off the incubator/shaker. Unplug the incubator/shaker from
the mains/power supply.
2. Dampen a clean cloth with the alcohol solution and wipe down all external surfaces, taking
care to keep the alcohol solution from coming into contact with any electrical outlets or
assemblies.
3. Remove all of the shelves, the humidity trays and the removeable shelf racks.
4. Place the black protective cover over the CO
2
sensor. Also protect any additional sensors,
such as Oxygen or Humidity, with the cover(s) supplied.
5. You can clean the humidity trays by rinsing them in sterile water, wiping them down with the
alcohol solution, and then rinsing them again with sterile water.
6. Wipe down the inside of the chamber with the alcohol/water solution, and leave it to dry
completely.
7. Wipe the internal components of the chamber twice with the alcohol/water solution. Wipe off
excess liquid and leave it to dry completely.
8. Wipe the inner door seal with the alcohol solution, rinse and leave it to dry.
CAUTION!
