Installation Guidelines
Safety Precautions
Before commencing any installation or replacement procedure, it is crucial to turn off the main water supply to the fixture. Subsequently, open the faucet handle to relieve any residual water pressure within the system. This ensures a complete water shut-off and prevents unintended water flow during the process, minimizing the risk of leaks or injury.
Installation Steps
- Ensure water supply is completely off as described in the safety precautions.
- Carefully remove the existing filter or component that is being replaced.
- Install the Moen 104400 Commercial Service Kit Filter, ensuring all connections are secure and properly tightened to prevent leaks.
- Slowly turn the water supply back on and check for any leaks around the newly installed filter.
- Test the faucet's operation to confirm proper functionality.
Care and Maintenance
To maintain the appearance and integrity of the metallic parts of your Moen faucet, including components associated with this service kit, follow these guidelines:
- Apply a non-abrasive wax, such as car wax, to preserve the finish.
- If using cleaners, rinse them off immediately with water to prevent damage to the finish.
- Mild abrasives are acceptable for Platinum and LifeShine® finishes only. For other finishes, avoid abrasive cleaners.
Troubleshooting
If you encounter issues after installing the Moen 104400 Commercial Service Kit Filter, consider the following:
- Leaks: Ensure all connections are securely tightened. Check for proper seating of any gaskets or O-rings.
- Reduced Water Flow: Verify that the filter is installed correctly and not obstructed. Ensure the main water supply valve is fully open.
- Persistent Problems: If issues persist despite troubleshooting, it is recommended to consult a qualified plumbing professional.
