4. Replace the top of the oxygen cell.
Note: Once you add the electrolyte, DO NOT add additional
electrolyte to the reservoir. If the level falls below the
minimum level, refer to Checking and Replenishing the
Electrolyte in the Delta F Oxygen Cell in Chapter 2 of the
Service Manual to replenish the cell.
5. Calibrate the Oxygen Cell as described in Calibrating the Delta F
Oxygen Cell in Chapter 2 of the Service Manual. After you
calibrate the cell, connect it to the gas line as described in the
following section.
To connect the oxygen sample system to the process line, attach a
1/8 inch O. D. (outside diameter) tube to the 1/8 inch sample gas inlet
®
fitting using a Swagelok
using plastic and rubber in any tubings or fittings that are included in
the inlet gas lines.
Do not connect the oxygen cell outlet to flow
restricting devices, pressure lines, or vacuum lines.
Pressure differentials across the cell sensor in excess
of 1 psig could be harmful or damage the cell.
If the gas being monitored does not create a safety hazard, vent it to
atmosphere at the sample system outlet. If venting the gas to
atmosphere causes a safety hazard, vent the gas to a safe location.
Make sure the venting system does not create a back pressure to the
oxygen cell.
The vented sample will not be corrosive if you install and operate the
cell properly.
