CAUTION!
Never leave water in the humidity tray while the incubator is switched
off, or when a high temperature disinfection cycle is initiated, to avoid
possible damage to the CO
2
sensor.
The humidity level within the chamber can be manually adjusted from ~95% to ~97%.
The controller to adjust the humidity level is found on the lower, front right side of the
instrument. The black adjustment knob can be rotated clockwise for standard (~95%)
humidity levels, and counter-clockwise to increase the humidity level.
NOTE:
The humidity tray should always be left in place, even if the incubator is
not being humidified.
