2. Undo the velcro straps.

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)}.
