Setup and Installation
Installation of the Moen Commercial Shower Trim requires professional plumbing knowledge. It is recommended that installation be performed by a qualified plumber.
- Valve Installation: Ensure that Moen valves #8731HD and #3360 are properly installed within the wall. These valves are critical for the functionality of the trim kit and are sold separately.
- Trim Kit Assembly: Follow the specific instructions provided with your valve and trim kit for assembling the handles, escutcheons, and other visible components.
- Showerhead and Handshower Installation: Securely attach the stationary showerhead, slide bar, hand-held shower, and metal hose according to the provided diagrams. Ensure all connections are watertight.
- Water Supply: After installation, slowly turn on the main water supply and check for any leaks.
This trim kit is designed for wall-mounted installation. The M-PACT common valve system allows for future style changes without needing to alter the in-wall plumbing.
Operating Instructions
The Moen Commercial Shower Trim features a single handle lever for controlling both water volume and temperature.
- Turning On/Off: Rotate the single handle to turn the water flow on or off.
- Adjusting Temperature: Rotate the handle counter-clockwise for warmer water and clockwise for cooler water. The Posi-Temp valve (if installed) will help maintain your desired temperature by balancing pressure fluctuations in the hot and cold water lines.
- Adjusting Volume: The volume is typically controlled by the degree of rotation of the handle.
- Handshower Use: The hand-held shower can be removed from its holder on the slide bar for directed water flow. It includes a non-positive pause function to temporarily reduce water flow.
Maintenance
Regular cleaning and maintenance will help preserve the finish and functionality of your Moen shower trim.
- Cleaning the Finish: Clean the brushed nickel finish with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Preventing Water Spots: To minimize water spots, wipe the trim dry after each use.
- Cartridge Maintenance: If you experience dripping or inconsistent water flow, the internal cartridge may need inspection or replacement. Moen cartridges are designed for durability, but wear can occur over time.
- Hose and Handshower: Periodically check the metal hose for kinks or damage. Ensure the handshower holder is secure and functioning correctly.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water dripping from showerhead/handshower. | Worn or faulty cartridge in the Posi-Temp valve. | Replace the valve cartridge (e.g., Moen 1222B cartridge). Contact Moen customer service for assistance or replacement parts. |
| Inconsistent water temperature (sudden hot/cold changes). | Pressure imbalance in hot/cold water lines; Posi-Temp valve not functioning optimally. | Ensure the Posi-Temp valve is correctly installed and functioning. If issues persist, the valve cartridge may need inspection or replacement. |
| Handshower falls off holder. | Holder mechanism worn or not securely tightened. | Inspect the handshower holder on the slide bar. Ensure it is securely fastened. If worn, replacement of the holder component may be necessary. |
| Low water pressure from showerhead/handshower. | Clogged showerhead/handshower nozzles; water restrictor in handshower. | Clean any mineral deposits from the nozzles. For the handshower, check for and carefully remove any water restrictors if higher flow is desired and permitted by local codes. |
