6.5 Replacing the Particulate Filter
The internal particulate filter (Figure 6-2) prevents small dust and dirt
particles from entering and damaging the pump. Depending on your
environmental conditions, it is recommended to change the particulate
filter and fitting approximately every six months, or sooner if it becomes
blocked.
Equipment Required:
• Particulate Filter and Fitting (Refer to Section 8.0)
Procedure:
1. Remove the analyzer’s rear case and lay it aside (refer to Section 6.2).
2. Carefully pull off the tubing from the filter and fitting. Note the
orientation of tubing and fitting before removing.
3. Remove and discard the old filter and fitting and replace with new
ones. Be careful not to not pinch the tubing during reassembly.
4. Reassemble the analyzer in the reverse order of disassembly.
