1. Introduction
Thank you for choosing the Kohler K-965-AK-AF Purist Single Function Katalyst Showerhead.

2. Safety Information
- Always turn off the main water supply before beginning any installation or maintenance.
- Wear appropriate personal protective equipment, such as safety glasses, during installation.
- Ensure all connections are secure to prevent leaks.

3. Package Contents
Verify that all components are present before installation:

- Rubber Washer/Seal (typically pre-installed or included)
4. Installation
Tools Required:
- Adjustable Wrench
- Plumber's Tape (Thread Seal Tape)
- Soft Cloth
Installation Steps:
- Turn Off Water Supply: Locate and turn off the main water supply to your shower.
- Remove Old Showerhead: If replacing an existing showerhead, unscrew it counter-clockwise from the shower arm. Use an adjustable wrench if necessary. Clean any debris from the shower arm threads.
- Apply Plumber's Tape: Wrap plumber's tape clockwise around the threads of the shower arm 3-4 times. This helps create a watertight seal and prevents leaks.
- Install New Showerhead: Hand-tighten the Kohler K-965-AK-AF showerhead onto the shower arm by turning it clockwise. Ensure the rubber washer is properly seated inside the showerhead connection.
- Tighten Securely: Use an adjustable wrench to tighten the showerhead an additional quarter to half turn. Do not overtighten, as this can damage the threads or the showerhead.
- Test for Leaks: Turn the main water supply back on and check for any leaks around the connection. If leaks occur, turn off the water, re-tighten, or re-apply plumber's tape.
5. Operation
The Kohler K-965-AK-AF Purist Showerhead is designed for single-function operation, providing a consistent and powerful spray pattern.
- Katalyst Air-Induction Technology: This showerhead incorporates Katalyst technology, which infuses air into the water stream. This process creates larger, fuller water droplets, enhancing the showering experience by providing a more focused and invigorating spray coverage.
- Optimized Sprayface: The sprayface features a specific nozzle geometry designed to deliver a concentrated flow of water, minimizing overspray and improving rinsing performance.

6. Maintenance
Cleaning the Showerhead:
- MasterClean Sprayface: The MasterClean sprayface is designed to resist hard water buildup. To clean, simply wipe the rubber nozzles with your finger or a soft cloth to dislodge any mineral deposits.
- General Cleaning: For the showerhead's finish, use a soft, damp cloth and a mild soap. Rinse thoroughly with water and dry with a soft cloth to maintain its appearance.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, or chemicals containing ammonia, bleach, or alcohol, as these can damage the finish.
7. Troubleshooting
Low Water Pressure:
- Check Water Supply: Ensure the main water supply is fully open.
- Clean Sprayface: Mineral buildup on the MasterClean sprayface can restrict water flow. Clean the nozzles as described in the Maintenance section.
- Inspect for Obstructions: If possible, carefully remove the showerhead and check for any debris or obstructions in the screen washer or shower arm.
Leaks from Connection:
- Re-tighten: Ensure the showerhead is securely tightened onto the shower arm.
- Re-apply Plumber's Tape: Turn off the water supply, remove the showerhead, and re-apply plumber's tape to the shower arm threads before re-installing.
- Check Washer: Verify that the rubber washer/seal is correctly seated and not damaged. Replace if necessary.
