Operating Instructions
The Moen Wynford Posi-Temp Shower Valve Trim Kit T5501 features a single handle for controlling both water flow and temperature. The Posi-Temp valve system is designed to maintain a consistent water temperature, preventing sudden changes due to pressure fluctuations from other water usage in the home.
Temperature Control:
- To turn on the water and increase temperature, rotate the handle counter-clockwise.
- To decrease temperature, rotate the handle clockwise.
- The handle typically rotates through a 180-degree arc, allowing for precise temperature adjustments.
Flow Control:
- The flow rate is controlled by the same handle. As you rotate the handle to adjust temperature, the flow will also increase.
- The maximum flow rate is typically limited to 2.5 gallons per minute (GPM) at 60 PSI.
Maintenance
To maintain the beautiful chrome finish and ensure the longevity of your Moen Wynford Posi-Temp Shower Valve Trim Kit T5501, follow these simple cleaning and care guidelines:
- Regular Cleaning: Clean regularly with mild soap and water. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the chrome finish. Products containing ammonia, bleach, or alcohol should also be avoided.
- Prevent Mineral Buildup: In areas with hard water, wipe down the trim kit after each use to prevent mineral deposits from forming.
