Page 29: Operation
OPERATION HEORY OF PERATION Heating When powered, the incubator heats to and maintains a user-selected target setpoint 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 setpoint, it pulses power to heating elements on the surface of the water-jacket insulation space and in the outer chamber door. - Page 30 OPERATION Atmosphere The incubator also controls and maintains the gas concentration of CO in the chamber atmosphere by operating an internal injection solenoid valve connected to a gas input port. The incubator monitors CO concentration level in the chamber using an infrared sensor located in the recirculation duct.

Page 31: Put The Incubator Into Operation
OPERATION Note: From a cold start, the incubator requires 12 hours to come up to and stabilize at temperature and humidity levels prior to loading samples. Stabilization safeguards samples. UT THE NCUBATOR INTO PERATION Perform the procedures below after the unit has been installed in a new workplace location. These prepare the incubator for normal use. - Page 32 OPERATION Continued from the previous page. Run the unit for at least 12 hours (for example, overnight) with chamber doors closed prior to: Setting the Over Temperature Limit (next step). • Loading samples. • This helps ensure a stable temperature environment. Perform the Set the Over Temperature Limit.

OPERATION TART A LOW OF Gas Cylinder(s) Open the cylinder valve to supply CO to the regulator. Set cylinder regulator flow setting. Single source: Set the regulator to deliver 15 – 20 Pounds per Square Inch (psi) to • the incubator CO in Port. -
Page 37: Set The Co Setpoint
OPERATION ET THE ETPOINT The incubator comes from the factory with the CO setpoint set to Off. Set the setpoint percentage to the gas concentration required by your study or production protocol. Navigate to the CO Setpoint Adjustment mode Briefly push and release either the Up or Down arrow buttons to activate the CO setpoint adjustment mode. -
Page 38: Muting The Audible Co Alarm
OPERATION UTING THE UDIBLE LARM Audible and visual deviation alarms activate if the incubation chamber CO concentration deviates by 1% above or below the CO setpoint. The low deviation audible alarm has a delay of 15 minutes to prevent the low alarm from sounding each time the doors are opened, causing a short-lived drop in CO concentration. -
Page 39: Set The Over Temperature Limit (Otl)
OPERATION Note: Test the OTL system at least once per year to verify its functionality. Failure to set the OTL 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 40: Loading Samples

This safeguards against temperature instability. • Samples should be placed at least 1 inch (25 mm) away from the chamber walls. •... -
Page 41: Data Output Capabilities
OPERATION UTPUT APABILITIES USB Outputs The incubator generates data outputs describing the chamber temperature and CO concentration percentage as a digital log line, once per minute. These outputs are transmitted through a USB port located on the right side of the unit using RS232 serial protocol. Required Software Viewing and logging this output requires a terminal emulator program such as the open source (BSD license) emulator, Tera Term. -
Page 42: Condensation And The Dew Point
OPERATION ONDENSATION AND THE OINT Relative humidity inside the incubator chamber should never be allowed to exceed 95%. Exceeding this threshold will likely result in condensation in the chamber and subsequent leakage from the incubator. This may cause corrosion damage if allowed to continue for any significant length of time. -
