3.2 Preparing for Operation
1. Remove the black protective cover from the CO
2
sensor (located on the back
surface of the internal chamber), and store it for use when you clean the
incubator. There is a storage holder for the cover on the front the unit, inside
the door.
2. Ensure that the white porous sensor cover remains in place.
3. Using the power cord provided, connect the incubator to a grounded power supply.
4. Switch the incubator ON using the on/off switch at the rear of the cabinet. The
display will illuminate immediately.
5. Turn on the CO
2
gas supply with the pressure regulator set to 5 psi or 0.35 bar.
NOTE:
Be certain to check for leaks in the CO
2
connections to avoid depleting
your CO
2
gas supply. This can be accomplished using a solution of
soapy water applied to each fitting and checking for bubbles. If any
bubbles are noted, readjust the fitting.
6. The chamber setpoints are pre-programmed at 37.0°C and 5% CO
2
. Leave the
incubator on until the programmed chamber temperature and CO
2
concentration
has been reached ( please see NOTE below ).
NOTE:
The incubator’s CO
2
valve is disabled until the incubator reaches the
temperature setpoint. After reaching the temperature setpoint, the
CO
2
valve is activated allowing the unit to reach the CO
2
setpoint. If
power is interrupted to the incubator long enough for the temperature
to drop below setpoint, the CO
2
valve will be deactivated until setpoint
is again achieved. (This serves to avoid spurious CO
2
readings while
the incubator is reaching its temperature setpoint)
7. Leave the incubator running for at least two hours (preferably overnight) to
allow conditions to stabilize.
3.3 Using the Humidity Tray & Humidity Control
If humidification is required, the humidity tray should be filled with 1.5 liters of
warm (
∼
37.0ºC) distilled water at this time.
