4. Operating Instructions
Your MONDAWE shower system is designed for ease of use, offering flexible control over water temperature and spray functions.
Temperature Control
The large rotary knob at the bottom of the control panel adjusts the water temperature. Rotate it towards the 'H' (Hot) indicator for warmer water and towards the 'C' (Cold) indicator for cooler water. The integrated pressure balance valve will automatically adjust to maintain your selected temperature, minimizing fluctuations caused by changes in household water pressure.
Function Selection
The three push-buttons located above the temperature knob allow you to select different shower functions:
- Top Button: Activates the 12-inch ceiling-mounted rainfall shower head.
- Middle Button: Activates the 6-inch wall-mounted shower head.
- Bottom Button: Activates the handheld spray.
You can use any of these functions independently by pressing a single button, or simultaneously by pressing multiple buttons to create a combined spray experience.

The control panel allows for independent or simultaneous activation of the 12-inch ceiling shower head, 6-inch wall shower head, and handheld shower, with temperature adjusted by the main knob.
5. Maintenance
Regular cleaning and basic maintenance will help preserve the appearance and functionality of your MONDAWE shower system.
Cleaning
- General Cleaning: Clean the shower heads, control panel, and other exposed surfaces regularly with a soft, damp cloth and mild, non-abrasive soap.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, ammonia-based products, or any harsh chemicals, as these can damage the matte black finish and internal components.
- Nozzle Maintenance: The silicone nozzles on both shower heads are designed for easy cleaning. Periodically, gently rub the nozzles with your finger or a soft brush to dislodge any mineral buildup and maintain optimal spray performance.
6. Troubleshooting
If you encounter any issues with your shower system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Pressure | Main water supply partially closed, mineral buildup in shower heads, kinked shower hose. | Ensure main water supply is fully open. Clean shower head nozzles by gently rubbing them. Check the shower hose for kinks or obstructions. |
| Water Temperature Fluctuations | Pressure balance valve malfunction, insufficient hot water supply. | Verify the pressure balance valve is correctly installed. Ensure your water heater is functioning properly and has adequate capacity. If issues persist, consult a professional plumber. |
| Leaks from Connections | Loose connections, worn washers or O-rings, insufficient pipe sealant tape. | Turn off water supply. Tighten all visible connections. Replace any damaged washers or O-rings. Reapply pipe sealant tape if necessary. |
| Water Leaking from Valve Body (Internal) | Defective valve cartridge or internal component. | This typically requires professional attention. Contact MONDAWE customer support or a qualified plumber. |
