Setup, Compatibility & Care
Installation of the CDC41CP-AG requires a standard side-entry water connection point. Ensure your furniture unit provides enough internal space for the 336mm width and 140mm depth. When installing, verify that the flush pipe is securely aligned with your toilet pan to prevent leaks. Routine care is minimal; however, due to the concealed nature of the unit, it is recommended to test the dual-access panels during installation to ensure they are accessible after the furniture is fully fitted. Periodically check the valves for sediment buildup if you live in a hard-water area to ensure the long-term performance of the filling mechanism.
