On or Alarm position. This battery system will not power the heaters, fan motor or gas control system. Only qualified service technicians should replace this battery. Replacement instructions and batteries are available from Thermo Scientific. Requirements • A high quality two-stage, low pressure 15 psig (1.056 kg/cm2) pressure regulator is required for proper operation of the CO gas supply.
These units are designed to operate under the following environmental conditions: • Indoor use only • Altitude up to 2000m • Maximum relative humidity 80% for temperatures up to 31°C • Main supply voltage fluctuations not to exceed 10% of the nominal voltage.

Note If user does not push any keys after approximately thirty seconds, the display will revert back to the normal Run mode . If a value was changed, whatever value was last displayed will be stored as the new setting. Midi 40 CO2 Incubator Thermo Scientific...
10. After the temperature is calibrated, it is recommended to remove the temp sensor from the inner chamber to ensure the humidity inside the chamber is not passing through the door seal. TC CO sensors require stable temp and RH environment to ensure accurate calibration! Thermo Scientific Midi 40 CO2 Incubator...
FYRITE, lower the CO control set point in Program mode 1.0% below your current set point, e.g. from 5% to 4%. This step is necessary to prevent CO2 gas injection during the calibration of the unit. Midi 40 CO2 Incubator Thermo Scientific...

Run mode; wait at least 2 to 3 minutes for the displayed value to auto-correct using the new offset value entered. The delay in the update is due to how the system microprocessor averages CO measurements, the displayed value will not update immediately! Thermo Scientific Midi 40 CO2 Incubator...
Control is now effectively switched to the overtemperature monitoring system. The overtemperature sensor is the chamber air sensor which also provides the signal for the digital display on the control panel. Thermo Scientific Midi 40 CO2 Incubator...

To avoid marring the surface, always rub in the direction of the finish polish lines. Caution Do not use aromatic solvents to clean the cabinet interior: residues could cause contamination of the cabinet environment. Thermo Scientific Midi 40 CO2 Incubator...
(refer to Gas Supplies in Section 3 and Figure 2-1). 5. Turn the gas supply (or supplies) to ON. 6. Turn the main power switch to ON. Midi 40 CO2 Incubator Thermo Scientific...
3. Slowly pull the paper strip from the outside. You should feel some resistance. 4. Repeat this test at 4 inch (10 cm) intervals around the door. If the door does not seal properly, call Technical Services; the gasket needs to be adjusted or replaced. Thermo Scientific Midi 40 CO2 Incubator...
