Installation Steps
- Turn off Water Supply: Locate the main water shut-off valve for your home or the specific bathroom and turn it off. Open the existing faucet to drain any remaining water.
- Remove Old Trim: Carefully remove the existing handles, escutcheon, and any other visible trim components. You may need a screwdriver to loosen retaining screws.
- Clean Surface: Thoroughly clean the area around the valve body on the wall to ensure a smooth and secure installation of the new escutcheon.
- Install Escutcheon: Apply a thin bead of plumber's putty or silicone sealant around the back edge of the new escutcheon plate. Position the escutcheon over the valve body and secure it to the wall using the provided mounting screws. Ensure it is level and tight.
- Install Handles: Attach the desired handle (lever or knob) to the valve stem. Secure it with the set screw, typically located on the underside of the handle. Test for proper engagement.
- Turn on Water Supply: Slowly turn the main water supply back on. Check for any leaks around the newly installed trim.
- Test Operation: Operate the handles to ensure proper water flow and temperature control.
Operating Instructions
Basic Operation
The Lasco 31675OB Universal Trim Kit allows for easy control of water flow and temperature. Depending on the handle type installed:
- Lever Handle: Typically, rotating the lever handle controls water temperature (e.g., counter-clockwise for hot, clockwise for cold), while pulling it outwards or pushing it inwards controls water flow (on/off).
- Knob Handle: Rotating the knob handle controls water temperature, and pulling it outwards or pushing it inwards controls water flow.
Familiarize yourself with the specific movement of your installed handle to achieve the desired water temperature and pressure.
Maintenance
Cleaning
To maintain the oil rubbed bronze finish and overall appearance of your trim kit, follow these cleaning guidelines:
- Use a soft, damp cloth and mild soap (non-abrasive) for regular cleaning.
- Avoid using abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Rinse thoroughly with clean water after cleaning and dry with a soft cloth to prevent water spots.
Preventive Maintenance
- Periodically check for any signs of leaks around the escutcheon or handle base. Address any leaks promptly to prevent water damage.
- Ensure all screws and connections remain tight. Do not overtighten.
Troubleshooting
