- Inspect Components: Unpack all parts and inspect for any shipping damage. Report any damage immediately.
- Tools Required: Ensure you have all necessary tools for plumbing installation (e.g., pipe wrench, sealant, measuring tape, level).
- Water Supply: Turn off the main water supply to your home before starting any plumbing work.

- Connect the hot and cold water supply lines to the designated inlets on the shower valve.
- Connect the outlets from the valve to the ceiling mount shower arm, side shower arm, and handheld shower hose connection.
- Install the ceiling mount shower arm and attach the 12-inch rainfall shower head.
- Install the side shower arm and attach the 6-inch side spray shower head.
- Install the handheld shower holder and connect the shower hose and handheld showerhead.
- Install the trim plate and handle onto the shower valve.

5. Operating Instructions
Your Woindo shower system features a single handle for temperature control and a three-button diverter for selecting shower functions.
5.1 Temperature Control
- The main handle controls the water flow and temperature. Rotate the handle to adjust the temperature from cold to hot.
5.2 Function Diverter
The three-button diverter allows you to easily switch between the top rainfall shower head, the side spray shower head, and the handheld showerhead. You can also use two functions simultaneously.

- Dual Function: Press any two buttons simultaneously to activate two shower heads at once.
Note: When three modes are turned on at the same time, the water pressure will be reduced. For optimal pressure, use one or two modes simultaneously. If strong water pressure is desired for lower floors or specific installations, a booster pump may be considered.

6. Maintenance and Care
Proper care and maintenance will ensure the longevity and appearance of your Woindo shower system.
- Cleaning the Finish: Clean the matte black finish regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for bathroom fixtures. Avoid harsh chemicals, abrasive cleaners, or scouring pads, as these can damage the finish.
- Cleaning Silicone Nozzles: The silicone nozzles on both shower heads are designed for easy cleaning. Simply rub your finger over the nozzles to dislodge any mineral buildup or debris. This helps maintain consistent spray performance.
- Water Spots: To prevent water spots, wipe down the shower heads and fixtures after each use with a soft, dry cloth.
- Filter Washers: Periodically check and clean the filter washers located in the connections of the shower heads and hose to prevent debris from affecting water flow.
7. Troubleshooting
If you encounter issues with your shower system, refer to the following common troubleshooting tips. For complex problems, contact a qualified plumber or customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Pressure | Mineral buildup in nozzles; clogged filter washers; multiple shower functions active; low household water pressure. | Clean silicone nozzles; check and clean filter washers; use fewer shower functions simultaneously; consult a plumber for household water pressure issues. |
| Leaks from Connections | Loose connections; worn washers/O-rings; improper installation. | Ensure all connections are tightened properly (do not overtighten); replace worn washers/O-rings; re-evaluate installation or contact a plumber. |
| Water Temperature Fluctuations | Issues with water heater; pressure balance valve malfunction. | Check water heater settings; if problem persists, a plumber may need to inspect the pressure balance valve. |
