6.2.3 Removing the Micro-Fuel Cell
The Micro-Fuel cell is located inside the stainless steel cell block
behind the front panel. Refer to Figure 6-1 for the B-2CXL cell and
Figure 6-2 for the Insta-Trace cell.
To remove an existing cell:
1. Remove power to the instrument by unplugging the power
cord at the power source.
2. Open the front panel door by pressing the release button on
the top right corner of the door all the way in with a narrow
gauge tool.
3. With one hand placed underneath the cell block ready to
catch the Micro-fuel Cell , lift up on the stainless steel gate in
front of the cell block. This releases the cell and cell holder
from the block. The cell and holder will fall out in your hand.
6.2.4 Installing a New Micro-Fuel Cell
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 on the holder with the screen side facing down.
Note: There is a small location hole drilled in the holder. This
hole mates with a guide pin on the bottom rear of the cell
block. The hole in the cell block holder must align with the
guide pin on the cell block.
2. With O-ring in place, align the guide pin with the hole on the
cell holder. Then, with the holder, lift cell into the cell block.
3. Push the gate on the cell block down so that the slots on the
side of the gate engage the locating screws on the side of the
block. This forces the holder into position and forms a gas-
tight seal.
