Product Overview

Key Features

• Pressure Balance Valve: Works by sensing the ratio of hot to cold water and adjusting one or the other to deliver desired temperature, ensuring consistent water temperature.
• Dual Handle Control: The main handle controls the temperature, while the smaller handle diverts the flow of water between two dedicated outlets, such as a showerhead or handshower.
• Independent Functionality: Supports two independent functions with no shared functionality, meaning it will only run the showerhead or handshower independently.
• High Flow Rate: Compatible with the RDD-2 rough-in valve (sold separately), supporting a flow rate of 5.5 GPM at 60 PSI for an immersive showering experience.
• Durable Construction: Crafted from brass with a polished chrome finish, ensuring longevity and a sleek aesthetic.

2. Setup and Installation

This Rohl Lombardia diverter trim is designed for wall-mounted installation. Proper installation requires the RDD-2 rough-in valve, which is sold separately. It is highly recommended that installation be performed by a qualified professional plumber to ensure compliance with local codes and proper functionality.

Pre-Installation Checklist

• Ensure you have the Rohl RDD-2 rough-in valve.
• Verify all necessary plumbing connections are accessible and correctly sized.
• Confirm water supply lines are shut off before beginning installation.
• Inspect all components for any damage prior to installation.

Installation Steps (General Overview)

1. Install the RDD-2 rough-in valve according to its specific instructions, ensuring it is securely mounted within the wall.
2. Connect hot and cold water supply lines to the rough-in valve.
3. Connect the two dedicated outlet lines (e.g., to showerhead and handshower) to the rough-in valve's diverter ports.
4. Once the rough-in valve is installed and tested, attach the trim plate and handles to the valve body, following the detailed instructions provided with the rough-in valve and trim kit.
5. Test for leaks and proper operation before sealing the wall.

3. Operating Instructions

The Rohl Lombardia Pressure Balance Diverter Trim provides precise control over water temperature and flow direction to your shower outlets.

Temperature Control

• The main handle (larger handle) controls the water temperature.
• Rotate the main handle to adjust the temperature from cold to hot. The pressure balance valve will automatically maintain a consistent temperature, minimizing fluctuations due to changes in water pressure from other household fixtures.

Diverter Function

• The smaller handle acts as the diverter, directing water flow to your desired outlet.
• This system supports two independent functions, meaning you can select either the showerhead or a handshower, but not both simultaneously.
• Move the smaller handle to the designated position for the showerhead or the handshower. Refer to your specific installation for the exact positions for each outlet.

4. Care and Maintenance

To maintain the pristine appearance and functionality of your Rohl Lombardia Pressure Balance Diverter Trim, follow these care guidelines.

Cleaning the Polished Chrome Finish

• Clean the polished chrome finish regularly with a soft, damp cloth and mild soap.
• Rinse thoroughly with clean water and dry immediately with a soft, lint-free cloth to prevent water spots.
• Avoid abrasive cleaners, harsh chemicals, ammonia-based products, or scouring pads, as these can damage the finish.
• For stubborn water spots, a solution of equal parts white vinegar and water can be used, followed by thorough rinsing and drying.

General Maintenance

• Periodically check for any leaks around the trim plate or handles. Address any leaks promptly to prevent water damage.
• If water flow diminishes, check for mineral buildup in the showerhead or handshower, and clean as per their respective manuals.

This section provides general guidance for common issues. For complex problems, it is recommended to contact a qualified plumber or Rohl customer support.

Common Issues and Solutions

• Low Water Flow:
  • Check if the main water supply is fully open.
  • Inspect the showerhead or handshower for mineral buildup or clogs. Clean or descale as necessary.

• Inconsistent Water Temperature:
  • Ensure the hot water heater is functioning correctly and set to an adequate temperature.
  • Confirm that the pressure balance valve within the rough-in unit is not obstructed or damaged. Professional inspection may be required.
• Leaking from Handles or Trim Plate:
  • Tighten any visible screws on the handles or trim plate, but do not overtighten.
  • If leaking persists, the internal cartridge of the rough-in valve may need inspection or replacement. This typically requires professional service.
