Setup and Installation
Installation of this thermostatic shower system requires expertise in plumbing and electrical wiring. It is strongly recommended to hire a certified professional for installation to ensure safety, proper functionality, and compliance with local building codes.
Key Installation Considerations:
- Rough-in Valve: The system includes a robust brass rough-in valve. Ensure adequate space and proper alignment within the wall for the valve and its connections.
- Ceiling Reinforcement: For the 27x16 inch ceiling-mounted shower head, ensure the ceiling structure can support its weight and the plumbing connections.
- Water Supply: Connect to hot and cold water lines according to standard plumbing practices. The thermostatic valve requires both for proper operation.
- Electrical Connection: The LED lighting and music features require a dedicated electrical connection. Follow all electrical safety guidelines and local codes.
- Body Jet Placement: Plan the placement of the six body jets for optimal coverage and massage effect.
- Adjustable Sliding Rod: Install the sliding rod for the handheld shower at a comfortable height, considering all users. The rod allows for vertical adjustment of the handheld shower.

Maintenance
Regular maintenance will ensure the longevity and optimal performance of your CASAINC shower system.
- Gentle Cleaning: Clean the shower system regularly with a soft cloth and mild soap or a non-abrasive bathroom cleaner. Avoid using harsh chemicals, abrasive sponges, or scouring powders, as these can damage the matte black finish and internal components.
- Finish Care: For the stainless steel components, a gentle polisher can be used to maintain its shine. Always wipe dry after cleaning to prevent water spots.
- Spigot Cleaning: Over time, mineral buildup can occur in the rubber spigots of the shower head and body jets. To clean, gently rub the rubber nozzles to dislodge any deposits. For deeper cleaning, individual rubber spigots can be carefully removed and cleaned.
- Anti-Scale Deposit: The system is designed with anti-scale features, but regular cleaning helps prevent hard water buildup, especially in areas with hard water.
Troubleshooting
If you encounter any issues with your shower system, refer to the common problems and solutions below. If the problem persists, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| LED lights not working | Electrical connection issue, component failure. | Check the electrical connection to the LED system. If the issue persists after a significant period of use (e.g., 1.5 years), the LED component may require replacement. Contact customer support. |
| Inconsistent water temperature | Thermostatic valve malfunction, insufficient hot/cold water supply. | Ensure both hot and cold water supplies are fully open. If the thermostatic valve is not maintaining a consistent temperature, it may require inspection by a professional plumber. |
| Low water pressure | Mineral buildup in nozzles, insufficient home water pressure, flow restrictor. | Clean the shower head and body jet nozzles to remove any mineral buildup. Verify your home's water pressure meets the system's requirements (2.5 GPM). Consult a plumber if home water pressure is consistently low. |
| Bluetooth music not connecting | Device not paired, Bluetooth signal interference, speaker issue. | Ensure the shower system's Bluetooth is active and your device is in pairing mode. Move closer to the shower system to reduce interference. Refer to the separate Bluetooth pairing guide. |
