Maintenance
Validation Check
Perform the following gas and temperature checks after all cleaning, disinfecting and sterilizing or at
least every two weeks to ensure the G185 is operating correctly.
Gas Calibration
It is VERY important that the G185 is not emptied of gas during calibration. To do so will cause unstable
gas levels and gas flow, and will result in a considerable time before the gas concentration is recovered
and becomes stable again. To ensure the G185 is not emptied of gas during the gas sampling please
follow these instructions. Always use a gas analyzer recommended by CooperSurgical. The calibration
procedure described here assumes the use of the G100 Gas Analyzer (Order Code: 11103) which
recirculates gas into the gas flow during sampling.
There are two methods for collecting gas samples from the incubator:
1.
Via the Gas Sample Port on the back of the unit
2.
Via each of the chamber lids
DO NOT
collect more than 0.1l of gas from the chambers.
Always check the gas concentration in the setpoint menu during sampling. If the gas concentration
differs more than 0.1% from the setpoint, allow the G185 to stabilize to the gas concentration setpoint
before taking the next gas sample.
Please note:
If not recirculating the gas, allow the incubator to stabilize for 3 minutes after each
sample collection. Ensure the gas analyser is prepared as per its user manual.
Via the Gas Sample Port
Remove the red cap from the Gas Sample Port and attach to the inlet of your gas analyzer. Make sure
•
there are no tubing leaks
•
the tubing between the sample port and gas analyzer is as short as possible, never more than
20cm
•
outside air is not drawn in
Compare the CO
2
readout with the value shown in the ‘CO2.C’ menu and adjust if necessary, see
NOTE:
Remember to put the protective red cap back on the port.
