6. Remove the cell from the probe, and dispose of it in an
environmentally safe manner.
5.3.4 Installing a New Micro-Fuel Cell
CAUTION: Do not touch the sensing surface of the cell. It is
covered with a delicate Teflon membrane that can
leak when punctured. The sensor must be replaced
if the membrane is damaged.
Before installing a new cell, check the O-ring in the base of the cell
holder. Replace if worn or damaged.
1. Place the Cell in the Probe with the sensing surface facing
outward (toward the screen in the Cap).
2. Screw the Probe Cap onto the Probe until it stops.
3. With the O-rings in place, push the assembled Probe down into
the Cell Holder—Cap Down—with a slight rocking motion
until it is seated on the bottom of the holder. This forces the
holder into position and forms a gas-tight seal.
5.3.5 Cell Warranty
The Class B-1 Micro-Fuel cell is standard in the Model 3000PB. This
cell is a long life cell and is warranted for 6 months from the date of
shipment. The customer should purchase only one spare cell (per section
5.3.1). Do not attempt to stockpile spare cells.
If any cell other than the B-1 is supplied with your instrument, check
Specific Model Information in the front of this manual for any special
information applying to your cell.
Caution: The B-1 cell is not designed for applications where
CO
2
is a major component in the sample, however
slight amounts will not adversely effect the cell
performance.
If a cell was working satisfactorily, but ceases to function before the
warranty period expires, the customer will receive credit toward the pur-
chase 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 you.
