CAUTION: Read the section Cell Warranty Conditions, below, before replacing the cell.

CAUTION: After replacing the Micro-Fuel Cell, the analyzer must be recalibrated. See Calibration in chapter 4.

5.2.2 Ordering and Handling of Spare Sensors

To have a replacement cell available when it is needed, TAI recom- mends that one spare cell be purchased when the current cell 's warranty period is approximately two thirds over.

CAUTION: Do not stockpile cells. The warranty period starts on the day of shipment. For best results, do not order a new spare cell to soon.

The spare cell should be carefully stored in an area that is not subject to large variations in ambient temperature (75 °F nominal), and in such a way as to eliminate the possibility of incurring damage.

CAUTION: Do not disturb the integrity of the cell package until the cell is to actually be used. If the cell package is punctured and air is permitted to enter, cell-life will

be compromised.

WARNING: THE SENSOR USED IN THE MODEL 3190 CON- TAINS AN ELECTROLYTE WHICH INCLUDES 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 A PHYSICIAN. (SEE APPENDIX, Material Safety Data Sheet—MSDS).

5.2.3 Removing the Micro-Fuel Cell

Refer to Figure 5-2 for an exploded view of the cell block and cell. To remove a spent or damaged Micro-Fuel Cell:

1.Disconnect the Power Source at the Control Unit.

2.Disconnect the connector from the cell block if possible.
