- Turn off the main water supply to the installation area.
- Mount the rough-in valve securely within the wall, ensuring it is plumb and at the correct depth relative to the finished wall surface. The valve includes clear wall-depth markings.
- Connect the hot and cold water supply lines to the designated inlets on the valve.
- Connect the outlets from the valve to the overhead shower arm and the handheld shower hose connection point.
- Perform a leak test before closing the wall.

4. Operating Instructions
The WELLFOR WB-SH003MB shower system features a dual-function control for water flow and temperature.

Figure 4.1: The control panel, featuring the lower handle for temperature adjustment and the upper knob for diverting water flow.
- Temperature Control: The lower handle controls the water temperature. Rotate it to adjust between hot (red indicator) and cold (blue indicator) water. The pressure balance valve will maintain a consistent temperature once set.
- Water Diverter: The upper knob is the 2-way diverter.
- Rotate the knob to the first position to activate the 10-inch overhead shower.
- Rotate the knob to the second position to activate the handheld shower sprayer.
- Ensure the diverter is fully engaged in either position for optimal water flow.

5. Maintenance
Regular maintenance will ensure the longevity and optimal performance of your WELLFOR shower system.
- Cleaning: Clean the matte black finish with a soft, damp cloth. For stubborn spots, use a mild soap solution and rinse thoroughly. Avoid abrasive cleaners, scouring pads, or chemicals containing ammonia, bleach, or alcohol, as these can damage the finish.
- Shower Head Nozzles: Periodically inspect the silicone nozzles on the overhead and handheld shower heads for mineral buildup. Gently rub the nozzles to dislodge any deposits.
- Cartridge Inspection: If you notice persistent drips or difficulty in temperature control, the ceramic cartridge may need inspection or replacement. This typically requires professional assistance.
- Hose Inspection: Check the flexible shower hose for any signs of wear, kinks, or leaks. Replace if necessary.
