Appendix L. CPEC300 Series Pump
Replacement
L.1 Introduction
A properly maintained CPEC300 system will exceed the lifetime of the
system’s pump. However, this section provides step-by-step instructions for the
user to replace the system pump, rather than needing to return the pump
enclosure to Campbell Scientific for replacement.
L.2 Removal
To remove a CPEC300 system pump, carry out the following steps:
1.
Place the pump module or system enclosure on a horizontal surface.
It is very difficult to replace the pump if the module is mounted
vertically on a tower.
2.
Remove the four, #10 self-sealing screws that hold the filter assembly
within the CPEC300 pump module or system enclosure (see FIGURE
). If these screws become lost or damaged, replace them with pn
26412.

3.
Stand the filter up in the enclosure and remove the tubing from the
filter inlet by loosening the nut with an 11/16” wrench. Remove the
tubing from the outlet of the filter by loosening the nut with a 9/16”
wrench (FIGURE
