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, being

careful not to lose the O-ring at the base of the threaded portion of
the cell.

3. Open Sensor Housing door on the front panel.

4. Replace the cell on the cell holder by screwing it clockwise into the

cell block until it is held firmly in the socket.

5. Insert the cell block electrical connector plug into the socket in the

sensor.

5.2.5 Cell Warranty Conditions

The Class I-22 Micro-Fuel cell is used in the Model 3300PA. This cell is

a long life cell and is warranted for 2 years (under specified operating condi-
tions—see Appendix) from the date of shipment. Note any Addenda attached to
the front of this manual for special information applying to your instrument.

With regard to spare cells, 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.
