4. Safety Information
Observe the following safety precautions during installation and use:
- Always turn off the main water supply to the faucet 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.
- If you are unsure about any step, consult a qualified plumber.
5. Setup and Installation
Follow these steps to install the Moen 98037 Handle Kit:
- Turn Off Water Supply: Locate the main water shut-off valves for your bathroom or the specific faucet. Turn them off completely to prevent water flow during installation.
- Remove Old Handle (if applicable): If replacing an existing handle, carefully remove it. This may involve unscrewing a cap, removing a screw, and then pulling the old handle off the valve stem.
- Prepare the Valve Stem: Ensure the valve stem is clean and free of debris.
- Place the Handle: Align the new Moen 98037 handle onto the valve stem. Ensure it sits flush and correctly engages with the stem's splines.
- Secure with Screw: Insert the provided mounting screw through the center of the handle and into the valve stem. Tighten the screw firmly but do not overtighten, as this can damage the handle or stem.
- Attach the Handle Cap: Place the clear plastic handle cap over the screw and onto the handle. It should snap or twist into place, covering the screw head.
- Restore Water Supply: Slowly turn the main water supply valves back on.
- Check for Leaks: Operate the newly installed handle to turn the water on and off. Inspect all connections for any signs of leaks. If leaks are detected, turn off the water supply and re-check connections.
6. Operation
The Moen 98037 Handle Kit provides intuitive control for your faucet. Rotate the handle to adjust water flow and temperature. The specific range of motion and temperature control will depend on the underlying faucet cartridge and valve assembly.
7. Maintenance
To maintain the appearance and functionality of your Moen 98037 Handle Kit:
- Cleaning: Clean the handle with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can scratch or damage the plastic finish.
- Inspection: Periodically check the handle for any looseness. If the handle feels loose, gently tighten the mounting screw (refer to Step 5 in Installation).
- Avoid Overtightening: Do not apply excessive force when operating the handle, as this can stress the internal components.
8. Troubleshooting
If you encounter issues with your Moen 98037 Handle Kit, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Handle is loose or wobbly. | Mounting screw is loose. | Remove the handle cap and gently tighten the mounting screw. Do not overtighten. |
| Difficulty turning the handle. | Mineral buildup or worn internal faucet cartridge. | Clean around the base of the handle. If the issue persists, the faucet's internal cartridge may need replacement (this kit does not include a cartridge). |
| Water leaks from around the handle base. | Improper installation or worn internal faucet seals/cartridge. | Ensure the handle is properly seated and the mounting screw is secure. If the leak continues, the issue is likely with the faucet's internal components, not the handle kit. Consult a plumber. |
