Quick installation guide
1. Verify all parts are present.
2. Position the waste body (F‑G‑H) over the sink opening, placing washers (E) and the overflow washer (I) correctly.
3. Align the square overflow cover (H) with the rear overflow hole and tighten the overflow screw (J) – avoid over‑tightening.
4. Secure the waste outlet using the foam washer (D), steel grating (C), and waste body (F); tighten screw (B).
5. Check that the overflow pipe (G) is straight and both ends are snug.
6. Fill the basin gradually to confirm there are no leaks.
