6. Operation
6.1. Dual-Flush System
The Eridanus Wall Hung Toilet features a dual-flush system for water conservation. The flush plate has two buttons:
- Small Button: Activates a partial flush (0.8 GPF) for liquid waste, saving water.

7. Maintenance
7.1. Cleaning the Toilet Bowl
The rimless design and wall-hung nature of the toilet make cleaning effortless. The smooth, fully glazed, non-porous ceramic surface prevents dirt accumulation.
- Use a mild, non-abrasive cleaner and a soft cloth or sponge.
- Avoid harsh chemicals, abrasive pads, or wire brushes, as these can damage the ceramic finish.
- Regular cleaning will maintain the toilet's appearance and hygiene.
