Note: The V-2600B or V-2600B-SF Series Valve is sold separately and is not included with this trim set.
4. Setup and Installation
This trim set is designed for easy installation onto a compatible Olympia V-2600B or V-2600B-SF Series Valve. Refer to the specific installation instructions provided with your valve for detailed rough-in and valve body installation steps.
Installation Steps:
- Prepare the Valve: Ensure the compatible Olympia V-2600B or V-2600B-SF Series Valve is properly installed and secured within the wall according to its specific instructions. Make sure the water supply is turned off.
- Install the Bonnet Sleeve: Slide the bonnet sleeve over the valve stem.
- Attach the Face Plate: Position the face plate against the finished wall, aligning it with the valve body and securing it with the provided screws. Ensure the plate is level.
- Install the Handles: Place the metal lever handles onto their respective valve stems. Secure them in place using the set screws, typically located on the underside of the handles. Tighten gently to avoid damage.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks. If any leaks are detected, turn off the water supply and re-tighten the connections.

5. Operating Instructions
Your Olympia 3DT-23913 trim set provides control over water temperature, flow, and three distinct shower functions.
- Water Flow and Temperature: Use the two metal lever handles to control the water flow and temperature. Typically, one handle controls the hot water and the other controls the cold water. Adjust both handles to achieve your desired temperature and flow rate.
- Three-Function Diverter: The central control (often integrated into the face plate or a third handle, depending on the specific valve) allows you to switch between three different shower functions (e.g., showerhead, hand shower, body sprays). Rotate or pull/push this control to select the desired water outlet.
6. Maintenance
Proper care and maintenance will ensure the longevity and appearance of your shower trim set.
- Cleaning: Clean the trim set regularly with a soft, damp cloth and mild soap. Rinse thoroughly with water and dry with a soft cloth to prevent water spots.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, scouring pads, ammonia-based cleaners, or any cleaners containing bleach, acids, or alcohol. These can damage the finish.
- Check for Leaks: Periodically inspect the trim set and connections for any signs of leaks. Address any leaks promptly to prevent water damage.
7. Troubleshooting
If you encounter issues with your shower trim set, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Partially closed stopcock on valve; debris in aerator/showerhead; low water pressure. | Ensure valve stopcocks are fully open. Clean showerhead/aerator. Check household water pressure. |
| Leaks from Handles/Face Plate | Loose connections; worn O-rings/gaskets (within valve). | Ensure handles and face plate screws are snug. If leaks persist, consult the valve manufacturer's manual or a plumber for internal valve component inspection. |
| Difficulty Changing Functions | Diverter mechanism obstruction or wear. | Ensure no debris is obstructing the diverter. If the issue persists, the diverter cartridge within the valve may need inspection or replacement by a qualified professional. |
| Inconsistent Water Temperature | Issues with hot/cold water supply; valve cartridge malfunction. | Verify hot and cold water supplies are functioning correctly. If the problem continues, the valve cartridge may require professional inspection or replacement. |
