Technical information
APPENDIX C
3/31/2008 Rev. 4.3 C - 2
The CI-301AD is shipped with fresh soda lime and silica gel in their appropriate tubes. If it should
become necessary to open a tube, hold it in both hands and use the thumbs to push the cap off. The
cotton balls should be replaced each time the tubes are refilled. Refer to the REPLACING
CONSUMABLE section for instructions on replacing the filters. When filling the tubes, gently tap
the bottom against a firm surface several times to help the material settle. Replace the top cap making
sure there is sufficient room in the tube. Press firmly to seal in place, and twist if necessary to seat the
O-rings. Replace the tube in the proper position on the CI-301AD.
To fill the water tube, remove the top cap in the same manner. The caps will come off along with an
internal assembly. This assembly deflects water bubbles from entering the system during operation.
You will notice a scribed line on the center of the tube. Add water to this line. Under no
circumstances should you fill the water tube above this line. Doing so may cause liquid to emerge
from the output under certain operating conditions creating potential damage to the connected gas
analyzer. Replace the top cap firmly, and place the tubes back in the correct position on the CI-
301AD. The water tube should be emptied if the unit is not used for more than one or two days.
CONNECTION TO POWER AND THE ANYLIZER
The CI-301AD requires 12V DC for operation. Refer to page A-4 and figure A-7 to connect the
power supply to the connector marked “12V DC” on the CI-301AD controller unit front panel.
Remove all
moisture on the controller panel. Plug the power connector to the jack marked “12V DC”
on the panel.
Before operation, connect the “OUT” port on the CI-301AD to the “INTAKE” port on the CI-340
(see Figure C-1). Adjust both control knobs to their minimum (fully counterclockwise) positions.
