To replace the cell: Figure 4-1

1. Open the enclosure door.

2. Undo the velcro straps.

3. Remove the insulation.

4. The cell block is located in the center of the unit.

Unscrew the cap on the bottom of the cell block. The

B-2C sensor should drop down once the cap is

removed.

Figure 4-1 Cell Block

NOTE: Before the cell is removed from its package, a zero gas

with low ppm oxygen flowing at a relative high rate

through the cell block can lessen the time it will take the

newly installed cell to drop to a zero reading.

3. Remove the new cell from its package, and carefully

remove the shorting clip.

WARNING: The sensor used in the Model OT-2 System uses

electrolytes which may contain substances that are

harmful if touched, swallowed, or inhaled. Avoid

contact with ANY fluid or powder in or around the

unit. What may appear to be plain water could

contain one of these toxic substances. In case of

eye contact, immediately flush eyes with water for

at least 15 minutes. Call physician. {See Appendix -

Material Safety Data Sheet (MSDS)}.
