Appendix H. CPEC200 Pump Replacement
FIGURE H-10. Proper positioning of CPEC200 in shell cover
5. Hold the pump assembly securely to the shell cover while replacing
the shell cover to the shell bottom. Make sure the fan does not slide
back out of its hole in the foam. Fasten the shell cover in place with
the six #4 screws (see FIGURE H-3).
6. Reconnect the tubing to the inlet and outlet of the filter assembly (see
step 2 of removal and refer to FIGURE H-3).
Hold the fitting with a backup wrench to make sure the fitting does
not unscrew from the filter holder lid. Be careful to not overtighten
the fittings as this could cause damage to the hardware. Finger
tighten the fittings first, then snug slightly with a wrench.
7. Rotate the filter holder into position and mount in the enclosure with
four #10 screws (FIGURE H-1).
Do not overtighten screws.
