Rear case cover for L series C12L and C24L controllers

Replacement Rear Cover for L Series Control Units C12L and C24L

To remove the rear cover, simply unscrew the 5 screws from the cover. Lift the cover off vertically to avoid disturbing any internal connections. 

When closing the new rear cover be sure to wiggle the lid over the foam covered SPV4 pump to ensure the correct fit. Replace the screws to finalise the rear cover replacement. 

Use the existing screws that came with your controller. Screws not included with the replacement rear panel.
