4. Test System: Slowly turn on the main water supply and check all connections for leaks. Test each shower function to ensure proper operation and water flow.

6. Operating Instructions

Your MFLASMF shower system features a single handle for controlling water flow and temperature, and a diverter to select between the three shower functions.

6.1 Water Flow and Temperature Control

• Turn On/Off: Lift the single handle to turn on the water flow. Push it down to turn off.
• Adjust Flow: The further you lift the handle, the greater the water flow.
• Adjust Temperature: Rotate the handle left for hot water and right for cold water. Adjust gradually to achieve your desired temperature.

6.2 Function Selection (Diverter)

The diverter knob allows you to switch between the rain shower head, handheld sprayer, and body spray massage jets. Note: Only one function can be active at a time. You cannot use all shower heads simultaneously.

• Rain Shower Head: Turn the diverter to the designated position for the rain shower. This provides a consistent, powerful rain shower experience.
• Handheld Sprayer: Turn the diverter to the position for the handheld sprayer. This offers flexibility for rinsing specific areas, cleaning the shower, or bathing children and pets.
• Body Spray Massage Jets: Turn the diverter to the position for the body spray jets. These horizontal spray heads can be adjusted for direction (up, down, left, right rotation) to provide a targeted massage.

7. Maintenance and Care

Regular cleaning and maintenance will ensure the longevity and optimal performance of your MFLASMF shower system.

7.1 Cleaning the Shower Heads

The rain shower head and handheld sprayer feature easy-to-clean rubber nozzles. Mineral deposits (limescale) can accumulate over time, affecting spray patterns.

• To Clean: Simply rub the rubber nozzles with your finger or a soft cloth to dislodge any mineral buildup.
• For stubborn deposits, use a mild descaling solution specifically designed for bathroom fixtures. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish.

7.2 General Cleaning

• Clean the black finish with a soft, damp cloth and mild soap.
• Do not use abrasive sponges, scouring pads, or chemical cleaners containing ammonia, bleach, or alcohol, as these can damage the finish.
• Wipe dry with a soft cloth to prevent water spots.

7.3 Concealed Valve Maintenance

The embedded box design allows for easier maintenance of the control valve. If the valve core ever needs replacement, it can be accessed and replaced without removing the entire wall, simplifying future repairs.
