4. Operating Instructions
The Galeon diverter allows you to direct water flow to various shower components. The handle operates in three distinct positions:
- Position 1 (Individual): Rotate the handle to the first detent to activate the primary shower component (e.g., showerhead).
- Position 2 (Shared): Rotate the handle to the middle detent to activate both the primary and secondary shower components simultaneously (e.g., showerhead and hand shower).
- Position 3 (Individual): Rotate the handle to the third detent to activate the secondary shower component (e.g., hand shower or body sprays).
Note: The specific functions of each position depend on how your rough-in valve and shower components are plumbed.
5. Care and Maintenance
To maintain the finish and performance of your Delta Faucet diverter, follow these guidelines:
- Cleaning: Clean with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or polishes that could damage the finish.
- Avoid Scratches: Do not use scouring pads, steel wool, or other abrasive materials.
- Regular Inspection: Periodically check for any leaks or changes in operation.
6. Troubleshooting
If you experience issues with your diverter, consider the following:
- No Water Flow / Reduced Flow: Ensure the main water supply is on. Check for any obstructions in the shower components.
- Diverter Not Switching Properly: Verify that the handle is fully rotated to each detent position. If issues persist, the diverter cartridge may need inspection or replacement. Refer to the rough-in valve's instruction manual for cartridge replacement procedures.
- Leaks: Check all connections for tightness. If leaks persist from the diverter trim itself, the internal seals or cartridge may require attention.
For complex issues or if troubleshooting steps do not resolve the problem, please contact Delta Faucet customer support.
