Figure 1: Charging the Monstake Automatic Soap Dispenser. Connect the provided USB charging cable to the dispenser's charging port and a power source.
2. Wall Mounting Installation
The dispenser can be easily wall-mounted using the traceless adhesive sticker, requiring no drilling. Ensure the installation surface is smooth and dry (e.g., tile, marble, glass wall).
- Clean the desired wall surface thoroughly and ensure it is dry.
- Peel off the protective film from the traceless adhesive sticker.
- Firmly press the sticker onto the wall at the desired location. It is recommended to install the dispenser approximately 0.65 ft (20 cm) above the countertop.
- Allow the adhesive to set for at least 24 hours before mounting the dispenser.
- Align the dispenser with the mounting bracket on the sticker and slide it down to secure it in place.

3. Filling the Dispenser with Soap
The dispenser has a large capacity of 450 ml (16 oz).
- Locate the rubber piece on the top of the dispenser and remove it to reveal the filling port.
- Pour foam soap directly into the dispenser.
- If using gel soap (hand soap, dish soap, body wash), dilute it with water before filling. The recommended dilution ratio is 10-30% gel/liquid soap to 30-70% water. Mix thoroughly.
- Replace the rubber piece securely after filling.

Maintenance
Cleaning
To clean the exterior of the dispenser, wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents. Avoid getting water into the charging port or sensor area.
Soap Compatibility
For optimal performance, use foam soap directly. If using gel soap, ensure it is diluted as per the instructions in the 'Filling the Dispenser with Soap' section. Avoid particle-containing soaps to prevent clogging and damage to the internal mechanism.
