This section provides general installation steps. Due to the complexity of plumbing systems, professional installation is highly recommended. Ensure you have all necessary tools and plumbing knowledge before proceeding. Always refer to local plumbing codes and regulations.
1. Pre-Installation Steps
- Turn off the main water supply to your home or the specific area where the installation will take place.
- Clear the installation area of any obstructions and ensure adequate workspace.
- Review the provided plumbing diagram (if included with the physical product) and ensure all components are accounted for.
- Prepare the wall for in-wall valve installation, ensuring the recommended in-wall depth of 3.5 inches (Min 3-3/8" - Max 3-3/4") is met.
2. Installing the Thermostatic Valve
- Mount the thermostatic valve body securely within the wall, ensuring it is level and at the correct depth according to the provided diagram.
- Connect the hot and cold water supply lines to the designated inlets (3/4 NPT) on the valve body. Ensure proper orientation (hot on left, cold on right).
- Connect the outlet lines (1/2 NPT) from the valve to the respective shower components: rainfall head, wall-mounted head, body jets, and handheld shower.
- Perform a thorough leak test by turning on the water supply and checking all connections before closing the wall.
3. Installing Shower Heads and Body Jets

Operating Instructions
1. Thermostatic Temperature Control
The lower knob on the valve panel controls the water temperature. The default safety setting is 38°C (100°F) to prevent scalding, especially for children and the elderly.
- To increase the temperature beyond 38°C (100°F), press the safety button located on the knob and turn it counter-clockwise.
- To decrease the temperature, simply turn the knob clockwise.
- The thermostatic valve will maintain a consistent water temperature, eliminating sudden fluctuations during your shower.

2. Function Selection
The four upper knobs on the valve panel control the individual shower functions. Each knob can be turned ON or OFF independently, allowing for simultaneous use of multiple functions.
- Turn the desired knob to the "ON" position to activate a specific shower function (e.g., handheld, rainfall, wall-mounted, body jets).
- Turn the knob to the "OFF" position to deactivate it.
- You can use functions individually or combine them for a customized showering experience.

Maintenance and Cleaning
Regular cleaning and proper maintenance will help preserve the appearance and optimal performance of your Dasan shower system.
- General Cleaning: Use a soft, damp cloth and a mild, non-abrasive soap or cleaner specifically designed for bathroom fixtures. Avoid harsh chemicals, abrasive cleaners, scouring pads, or steel wool, as these can damage the brushed nickel finish.
- Nozzle Cleaning: The shower heads and body jets are equipped with flexible silicone nozzles. To remove mineral buildup (limescale), simply rub your finger across the nozzles. This helps maintain consistent water flow.
- Finish Care: The electroplated surface and glazed finish are designed to resist fingerprints and water stains. To keep the system looking its best, wipe all surfaces dry with a soft cloth after each use to prevent water spots and mineral deposits.

Troubleshooting
If you encounter any issues with your shower system, please refer to the table below for common problems and their solutions. If the problem persists, contact customer support or a qualified plumber.
| Problem | Possible Cause | Solution |
|---|---|---|
| No water flow or low pressure from a specific component. | Function knob not fully open; clogged nozzles; water supply issue. | Ensure the corresponding function knob is fully in the ON position. Clean nozzles by rubbing them to remove mineral buildup. Check main water supply pressure. |
| Water temperature is too hot or too cold. | Thermostatic valve setting incorrect; hot/cold water supply imbalance. | Adjust the thermostatic temperature knob. If adjusting beyond 38°C (100°F), press the safety button. If persistent, consult a plumber to check water supply lines and pressure balance. |
| Leaks at connections. | Loose connections; damaged O-rings/gaskets; improper sealant. | Turn off water supply. Carefully tighten all connections. Inspect and replace O-rings or gaskets if damaged. Reapply plumber's tape or sealant if necessary. |
| Water spots or discoloration on the finish. | Mineral deposits from hard water; improper cleaning agents. | Wipe all surfaces dry with a soft cloth after each use. Clean with a soft cloth and mild, non-abrasive cleaner specifically for brushed finishes. |
