4.2. Filling the Soap Reservoir
The dispenser has a 400ml (13.53oz) capacity reservoir. It is compatible with foaming soap, liquid soap, and gel soap.

- Pour the prepared soap solution into the reservoir through the wide filling port. Do not overfill.
- Align the top section with the base and twist clockwise until securely locked.
