3. Before You Begin Installation
This product is a trim kit only. A Delta MultiChoice Universal Shower Valve (rough-in valve) is required for complete installation and functionality. Recommended rough-in valve models include R10000-UNBX or R10000-UNBXHF. Ensure you have purchased and installed the correct rough-in valve before proceeding with the trim kit installation.

Image 2: This diagram illustrates that the rough-in valve is sold separately and provides key dimensions for the trim kit, including a valve trim width of 6.5 inches.
Installation may require access to plumbing behind the wall. If you do not have existing access, professional assistance may be necessary to avoid damage to your wall or plumbing system.

4. Setup and Installation
For detailed installation instructions, please refer to the official Installation Manual (PDF) provided by Delta Faucet. A digital copy can be accessed here.
Key Installation Steps (Summary):
- Prepare the Rough-In Valve: Ensure the Delta MultiChoice Universal Valve is correctly installed and secured within the wall, following its specific instructions.
- Install the Cartridge: Insert the Monitor Pressure-Balanced Valve Cartridge (included with this trim kit) into the rough-in valve body.
- Mount the Escutcheon: Secure the escutcheon plate to the wall over the valve body.
- Attach the Handle Assembly: Connect the dual-function handle components to the cartridge stem and escutcheon.
- Test for Leaks: Turn on the water supply and check all connections for leaks.

5. Operating Instructions
The Delta Trinsic 17 Series features a dual-function handle for precise control over your showering experience.
- Volume Control: The outer handle controls the water volume. Rotate it to increase or decrease the flow.
- Temperature Control: The inner handle controls the water temperature. Rotate it to adjust between hot and cold.
The integrated Monitor Pressure-Balanced Valve Cartridge maintains a consistent shower temperature by balancing hot and cold water pressure. This technology helps prevent sudden temperature changes caused by other household water usage.

6. Maintenance and Cleaning
To maintain the appearance and performance of your Delta Faucet Trinsic trim kit, follow these cleaning guidelines:
- General Cleaning: Clean with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- SpotShield Finish: The Matte Black finish features SpotShield technology, which resists water spots and fingerprints. Wipe with a soft cloth to keep it clean.
- Touch-Clean Spray Holes: If your showerhead (sold separately) has Touch-Clean spray holes, you can easily wipe away calcium and lime buildup with a touch of a finger.
7. Troubleshooting
If you encounter issues with your shower trim kit, consider the following common troubleshooting steps:
- Low Water Flow:
- Check if the main water supply is fully open.
- Inspect the showerhead for mineral buildup and clean if necessary (especially if it has Touch-Clean features).
- Ensure the volume control handle is fully open.
- Inconsistent Water Temperature:
- Verify that the hot and cold water supplies are correctly connected to the rough-in valve.
- Ensure the temperature limit stop on the cartridge is set correctly (refer to the full installation manual for adjustment).
- If the issue persists, the pressure-balanced cartridge may need inspection or replacement.
- Leaks:
- Turn off the water supply immediately.
- Check all connections for tightness.
- Inspect O-rings and gaskets for proper seating and damage.
For more complex issues, it is recommended to consult the full installation manual or contact Delta Faucet customer support.
