Page 25: Operation
OPERATION HEORY OF PERATION Heating When powered, the incubator heats to and maintains a user-selected target set point in the incubation chamber. The incubator senses the chamber air temperature using a solid-state probe mounted on the chamber interior wall. When the incubator detects that the chamber temperature has dropped below the target set point, it pulses power to the heating element inside the chamber heating duct in the chamber ceiling. -

Page 28: Set The Over Temperature Limit (Otl)
OPERATION Test the OTL system at least once per year to verify its functionality. Failure to set the OTL Note: voids the manufacturing defect warranty if over temperature damage occurs. (OTL) ET THE EMPERATURE IMIT This procedure sets the mechanical heating cutoff to approximately 1˚C above the current chamber temperature. -
Page 29: Loading Samples
OPERATION OADING AMPLES The manufacturer strongly recommends waiting at least 8 hours after putting the incubator in operation before loading samples in the chamber. This safeguards against temperature instability. Samples should be placed at least 1 inch (25 mm) away from the chamber walls. •... -
Page 30: Condensation And The Dew Point
OPERATION ONDENSATION AND THE OINT Relative humidity inside the incubation chamber should never be allowed to exceed 80% at 25°C. Exceeding this threshold will likely result in condensation or possible leaks around the incubator, and may cause corrosion damage if allowed to continue for any significant length of time. Condensation takes place whenever the humidity level in the incubation chamber reaches the dew point. -

Press and hold both the Up and Down temperature arrow buttons simultaneously for approximately 5 seconds. b. Release the buttons when the temperature display shows the letters “C O”. The display will begin flashing the current temperature display value.
- Page 37 MAINTENANCE Temperature Calibration Continued Compare the reference device reading with the chamber Reference Device temperature display. If the reference device and the chamber temperature • display readings are the same or the difference falls within the range of your protocol, the incubator is now calibrated for temperature.
