5.2.4 Installing a Micro-fuel Cell
To install a new micro-fuel cell:
CAUTION: Do not scratch, puncture, or damage the sensing
membrane of the Micro-fuel cell sensor. Damage
to the membrane will require replacement of the
sensor.
1. Disconnect the power source from the unit.
2. Remove the new micro-fuel cell from its protective bag.
3. Examine the O-ring at the base of the threaded portion of the cell
retainer cap and replace it if it is worn of damaged.
4. Replace the cell on the end of cell-retainer cap, which is
designed to fit snugly into the rim on the screen side of the cell.
5. Carefully insert the cap and cell into the block, and screw the cap
clockwise into the cell block until it is held firmly in the cell.
6. Reconnect the cell block electrical connector plug.
5.2.5 Cell Warranty Conditions
The Class A-2C, B-2C or Z-2C micro-fuel cell is used in the Model
3190. These cells are warranted for 6 months, with an expected life of 8
months from the date of shipment (under specified operating
conditions—see Appendix). Note any Addenda attached to the front of
this manual for special information applying to your instrument.
Note that the warranty period begins on the date of shipment. The
customer should stock only one spare cell per instrument at a time. Do
not attempt to stockpile spare cells.
If a cell was working satisfactorily, but ceases to function before
the warranty period expires, the customer will receive credit toward the
purchase of a new cell.
If you have a warranty claim, you must return the cell in question to
the factory for evaluation. If it is determined that failure is due to faulty
workmanship or material, the cell will be replaced at no cost to the
customer.
Note: Evidence of damage due to tampering or mishandling will
render the cell warranty null and void.
