6.
Select the required gas control mode.
7.
Use default target settings or set a gas concentration level using the plus
and minus keys. If no changes occur for 1 minute, the recently user-
defined target value will be saved to memory and used as new default
target value.
8.
Ensure that gas tubes from CO
2
gas supply and N2 gas supply are
connected to correct inlet ports ‘CO2’ and ‘N2’ on the rear of the GCM.
9.
Ensure that all gas tubes are tightly connected to gas supply (pressure
reduction valve), the gas control module, and the Infinite 200 PRO
10.
Check that the pressure is set correctly and that the valves of the gas
cylinder are open to allow the flow of gas:
•
Slowly open the main valve of the cylinder or manifold (Step 1), then
open the shut-off valve (Step 2). When using CO2 or N2 use a low
pressure of about 1.0 - 2.0 bar (14.5 - 29.0 psi) by turning the
pressure reduction valve (Step 3).
•
If necessary, disconnect the tube from the gas control module’s inlet
port on the back and adjust the outlet pressure by turning the pressure
reduction valve and pressing in the quick connector’s valve (Step 4)
(see Figure 34, below).
The selected pressure/flow rate is to be kept constant for the entire incubation
time.

IMPORTANT
DURING GAS SUPPLY KEEP THE INJECTOR PORT CLOSED
WITH THE INJECTOR PORT CAP, IF THE INJECTOR IS NOT IN USE.
IMPORTANT
BEFORE OPENING THE MAIN VALVE, ENSURE THAT THE
REGULATOR AND THE SHUT-OFF VALVES ARE CLOSED.
