Installation Instructions
Tools Required: Adjustable wrench, plumber's tape, soft cloth.
- Turn Off Water Supply: Locate the main water shut-off valve and turn off the water supply to the shower area.
- Remove Old Hand Shower (if applicable): Unscrew the existing hand shower or showerhead from the shower hose or wall mount. Clean any residue from the connection point.
- Prepare Connections: Apply plumber's tape clockwise to the threaded connections of the shower hose or wall mount arm. This helps create a watertight seal.
- Attach Hand Shower: Carefully screw the Riobel 4370-WS Hand Shower onto the shower hose or wall mount. Hand-tighten first, then use an adjustable wrench to tighten an additional quarter turn. Do not overtighten, as this can damage the threads or the product.
- Check for Leaks: Turn the water supply back on slowly and carefully observe all connections for any signs of leaks. If leaks are present, turn off the water, tighten the connection slightly, and re-check.
- Test Operation: Test the hand shower's functions to ensure proper water flow and spray patterns.
Operating Your Hand Shower
The Riobel 4370-WS Hand Shower features multiple spray functions designed for a customized showering experience.
- Changing Spray Functions: To switch between the 3 distinct spray functions, rotate the outer ring or a designated selector on the showerhead. Refer to the visual indicators on the showerhead for specific spray patterns.
- Water Flow: The hand shower provides a consistent flow rate of 1.75 gallons-per-minute (GPM) at standard water pressure.
Care and Maintenance
Proper care will ensure the longevity and preserve the polished nickel finish of your hand shower.
- Regular Cleaning: Clean the hand shower regularly with a soft, damp cloth and mild, non-abrasive soap.
- Avoid Abrasives: Do not use abrasive cleaners, harsh chemicals, ammonia-based products, or scouring pads, as these can permanently damage the polished nickel finish and the rubber nozzles.
- Mineral Deposits: For mineral deposit buildup on the rubber nozzles, gently rub them with your finger or a soft brush to dislodge the deposits. This helps maintain optimal spray performance.
- Drying: After cleaning, wipe the hand shower dry with a soft, clean cloth to prevent water spots and maintain its luster.
Troubleshooting
Review the following common issues and solutions before contacting customer support.
- Low Water Flow:
Cause: Clogged nozzles or mineral buildup within the showerhead.
Solution: Clean the nozzles as described in the Maintenance section. Ensure the main water supply valve is fully open. - Leaks at Connection Points:
Cause: Loose connection, improperly applied plumber's tape, or worn-out seals.
Solution: Turn off water supply, re-apply plumber's tape to the threads, and re-tighten connections. Check seals for damage and replace if necessary. - Difficulty Changing Spray Functions:
Cause: Mineral buildup or debris in the function selector mechanism.
Solution: Clean the showerhead thoroughly, paying particular attention to the function selector and surrounding areas.
