Appendix J. AP200 Pump Replacement
J.1 Introduction
A properly maintained AP200 system will exceed the lifetime of the system’s
pump. This section provides step-by-step instructions for the user to replace
the system pump (pn 26402), rather than needing to return the pump enclosure
to Campbell for replacement.
J.2 Removal
The AP200 pump module is mounted to the left side of the AP200 system
enclosure as shown in FIGURE J-1.

To remove an AP200 pump, carry out the following steps:
1. Place the pump module on a horizontal surface.
It is very difficult to replace the pump if the module is mounted
vertically on a tower.
