Setup and Installation
Professional installation by a qualified plumber is highly recommended for this shower system to ensure proper function and compliance with local plumbing codes.
Pre-Installation Checklist:
- Verify all components are present and undamaged.
- Ensure water supply lines are accessible and correctly sized.
- Confirm wall structure can support the installation.
- Review local plumbing and building codes.
General Installation Steps:
- Turn off Water Supply: Locate the main water shut-off valve and turn off the water supply to the installation area.
- Install Rough-In Valve: Mount the thermostatic pressure balance rough-in valve securely within the wall, ensuring it is level and at the correct depth according to the manufacturer's specifications.
- Connect Water Lines: Connect the hot and cold water supply lines to the designated inlets on the rough-in valve. Connect the outlets to the shower head, hand shower, and body jets.
- Install Shower Arm and Head: Secure the shower arm to the wall outlet and attach the shower head.
- Install Hand Shower Rail: Mount the hand shower rail at the desired height and connect the hand shower hose to the valve outlet.
- Install Body Jets: Install the four body jets into their pre-drilled locations, ensuring proper sealing.
- Install Trim and Handles: Once all plumbing connections are complete and tested, install the decorative trim plate and control handles.
- Test for Leaks: Slowly turn on the main water supply and carefully inspect all connections for leaks.
Operating Instructions
Your Riobel shower system offers precise control over water temperature and flow.
Temperature Control:
- The thermostatic handle controls the water temperature. Rotate the handle to adjust to your desired temperature.
- The system maintains the set temperature even if there are fluctuations in the hot or cold water supply pressure.
- An anti-scald safety stop is typically integrated to prevent accidental setting of excessively hot temperatures. To exceed this limit, a button or ring usually needs to be pressed or rotated.
Flow and Diverter Control:
- The coaxial handle controls the water flow and diverts water to different outlets.
- Turn On/Off: Rotate the outer ring of the coaxial handle to turn the water flow on or off.
- Divert Water: Push or pull the inner part of the coaxial handle, or rotate it, to select between the shower head, hand shower, and body jets. Refer to the markings on your trim for specific positions.
- Some systems allow for multiple outlets to be active simultaneously, while others are designed for single-outlet operation.
Maintenance
Regular cleaning and maintenance will help preserve the finish and functionality of your Riobel shower system.
Cleaning the Finish:
- Use only a soft, damp cloth and mild soap (e.g., dish soap) for cleaning.
- Rinse thoroughly with clean water immediately after cleaning and dry with a soft cloth to prevent water spots.
- Avoid: Abrasive cleaners, harsh chemicals, ammonia-based products, scouring pads, or steel wool, as these can damage the finish.
Shower Head and Body Jet Maintenance:
- Periodically inspect the nozzles of the shower head and body jets for mineral buildup.
- Many Riobel shower heads feature flexible silicone nozzles that can be easily cleaned by gently rubbing them with your finger to dislodge mineral deposits.
- For stubborn deposits, a solution of equal parts white vinegar and water can be used. Soak the affected parts (if removable) or apply the solution with a cloth, then rinse thoroughly.
