To replace the cell:
1. Open the enclosure door.
2. The cell block is located in the center of the unit. Unscrew the
cap on the bottom of the cell block. The micro-fuel cell should
drop down once the cap is removed.
NOTE: Minimize the amount of time the cell is exposed to air. This will
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.
NOTE: Do not touch the silver colored sensing surface of the cell, as it is
covered with a delicate Teflon membrane that can be ruptured in
handling. Puncturing or other damage will require replacement of
the sensor
WARNING: The sensor used in the Model 300P uses electrolytes which
contain substances that are extremely 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)).
4. Place the new cell on the cap with the sensing surface face
down and the gold contact rings up.
5. Position the cell and cap so that the cell is inside the cell block.
Press up on the cap and rotate until it threads. Tighten the cap.
