6. Operating Instructions
The CASAINC Luxury Shower System offers three distinct functions for a personalized showering experience.
6.1. Water Flow and Temperature Control
The main handle on the valve controls both water flow and temperature. Rotate the handle to adjust the temperature from cold to hot. Lift or push the handle to turn the water on or off and adjust flow intensity.
6.2. Function Selection
The diverter knob allows you to switch between the three spray functions:
- Rainfall: Provides a gentle, wide coverage shower from the large overhead shower head.
- Waterfall: Delivers a broad, cascading sheet of water from the overhead shower head, ideal for a luxurious experience.
- Handheld Spray: Activates the flexible handheld shower for targeted rinsing or cleaning.

7. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your CASAINC shower system.
7.1. Cleaning the Shower Heads and Handheld Spray
- The rubber nozzles on the shower head and handheld spray are designed for easy cleaning. Simply rub them with your finger or a soft cloth to remove mineral buildup.
- For general cleaning, use a soft cloth and mild soap or a non-abrasive bathroom cleaner.
- Avoid using abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the brushed gold finish.
- Rinse thoroughly with clean water after cleaning and wipe dry to prevent water spots.
7.2. Valve and Finish Care
- The advanced electroplating coating technology makes the finish durable and spot resistant.
- Wipe down the valve trim and handles regularly with a soft, damp cloth to maintain their appearance.
- Do not use cleaners containing ammonia, bleach, or alcohol, as these can degrade the finish over time.
