Replacing the Cell
1.
Thread the new cell assembly into the inner probe assembly until
handtight. Use a magic marker to mark the left hex nut with the same
orientation mark as the mark on the inner probe assembly.
For example, if the mark on the inner probe assembly is positioned at
3 o'clock, place a mark at 3 o'clock on the left hex nut of the cell assem-
bly.
2.
Unscrew the cell assembly from the inner probe assembly.
3.
Slide the heater, cell clips, and cell leads forward through the end of
the inner probe assembly until the cell clips are exposed.
4.
Slide the new metal O-ring over the heater and cell clips assembly so
that it is positioned at the end of the inner probe assembly. Use a new
metal O-ring when reassembling to ensure a proper seal. A new metal
O-ring is included with the cell replacement kit.
5.
Slide the non-slotted ceramic washer over the open end of the cell and
then slide the slotted ceramic washer over the open end of the cell.
6.
Slide the cell clips off of the heater.
7.
Slide the cell assembly over the heater so the cell clips align with the
open end of the cell. Ensure that the heater is as far inside the cell as
possible to help support the cell.
8.
Find the cell clip associated with the white cell wire. Wiggle the wire
back and forth to find the right wire. Rotate the cell assembly so that
the mark on the left hex nut is aligned with where the cell clip is
welded to the cell lead. Take the white cell clip and snap it onto the
cell, placing it between the white band on the cell and the open end of
the cell.
Don't allow the white ceramic tube to be trapped between the cell clip
and the cell. Only the clip should touch the cell.
NOTE
9.
Using a flat blade screwdriver, snap the new retainer clip over the cell
clip to provide a strong contact between the cell clip and the cell. The
retainer clip is concave - place the pointed end away from the cell.
10. Position the slotted ceramic washer over the white band of the cell. At
the same time, rotating it so that the blue cell lead can pass through
the slot in the washer.
