The CO2 gas supply being connected should be industrial grade 99.5%
pure and should not contain siphon tubes. Install a two-stage pressure
regulator at the cylinder outlet. The high pressure gauge at the tank should
have 0-2000 psig range. The low pressure gauge, at the incubator inlet,
should have a 0-30 psig range. Input pressure to the incubator must be
maintained at 15 psig (103.4 kPa).
The incubator has serrated fittings on the back of the cabinet to connect
the gas supply. Refer to Figure 1-11. The fitting is labeled CO2 Inlet #1
Tank. Make sure that the connections are secured with clamps. Check all
fittings for leaks.
For units having the CO
2 Gas Guard option, refer to Section 6.
With the incubator properly installed and connected to power, the
humidity pan filled, and the unit connected to gas supplies, system
setpoints can be entered. The following setpoints can be entered in Set
mode: Temperature, Overtemperature and CO
2. To enter Set mode, press
the Mode key until the Set indicator lights. Press the right and/or left
arrow keys until the proper parameter appears in the message center. See
Chart 1-1 for more detail.
Model 310 Series incubators have an operating temperature range of 10°C
to 50°C, depending on ambient temperature. The incubator is shipped
from the factory with a temperature setpoint of 10°C. At this setting, all
heaters are turned off. To change the operating temperature setpoint:
1. Press the Mode key until the Set indicator lights.
2. Press the right arrow until “Temp XX.X” is displayed in the message
center.
3. Press the up/down arrow key until the desired temperature setpoint is
displayed.
4. Press Enter to save the setpoint.
5. Press the Mode key until the Run indicator lights for Run mode or
press the right/left arrow keys to go to next/previous parameter.
