4. Installation Guide
The Cordivari Lisa 22 towel warmer is designed for easy connection to US standard pipes and central heating systems. Professional installation is recommended.
4.1 Pre-Installation Checks
- Verify that the wall where the radiator will be installed is structurally sound and can support the weight of the unit when filled with water.
- Ensure that the pipe centers match the radiator's specifications (20 inches / 500 mm).
- Confirm that all necessary tools and safety equipment are available.
4.2 Mounting the Radiator
- Marking: Using the provided template or measurements, mark the drilling points on the wall for the mounting brackets. Ensure the marks are level and correctly spaced.
- Drilling: Drill holes at the marked points using an appropriate drill bit for your wall type. Insert the wall plugs.
- Attaching Brackets: Secure the mounting brackets to the wall using the provided screws. Ensure they are firmly attached.
- Positioning Radiator: Carefully lift the towel warmer and position it onto the mounted brackets. Ensure it is securely seated.
4.3 Plumbing Connections
- Connect Valves: Attach the thermostatic valve and return valve to the radiator's connections (n° 2 x 1/2” gas). Use appropriate sealant or PTFE tape to ensure watertight connections.
- Connect to System: Connect the radiator's valves to your central heating system's supply and return pipes.
- Air Vent: Install the air vent (n° 1 x 1/2” gas) at the top of the radiator. This allows for bleeding air from the system.
- Leak Test: Once all connections are made, slowly fill the heating system and check for any leaks at all connection points. Tighten as necessary.

5. Operating Instructions
The Cordivari Lisa 22 Hydronic Towel Warmer operates as part of your central heating system. The thermostatic valve allows for control over the heat output.
- Thermostatic Valve: The thermostatic valve automatically regulates the flow of hot water through the radiator to maintain a desired room temperature. Turn the knob to adjust the setting. Higher numbers typically indicate higher heat output.
- Drying Towels: Hang towels evenly over the bars of the warmer. Do not overload the unit, as this can impede heat distribution and drying efficiency.
- Bleeding Air: If the radiator is not heating evenly (cold spots), it may have air trapped inside. Use the air vent key to slowly open the air vent until water begins to escape, then close it. Perform this operation when the heating system is cold.
6. Maintenance
Regular maintenance will ensure the longevity and efficient operation of your Cordivari Lisa 22 towel warmer.
- Cleaning: Clean the surface of the radiator regularly with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the ecological epoxy powder finish.
- Inspections: Periodically check all pipe connections for any signs of leaks or corrosion. Address any issues promptly.
- System Pressure: Ensure your central heating system maintains the correct operating pressure as recommended by your heating system manufacturer.
- Bleeding: Bleed the radiator annually, or whenever cold spots are noticed, to remove trapped air and ensure optimal heating performance.
7. Troubleshooting
This section provides solutions to common issues you might encounter with your towel warmer.
- Radiator Not Heating:
- Check if the central heating system is operational.
- Ensure the thermostatic valve is open and set to a desired temperature.
- Bleed the radiator to remove any trapped air.
- Verify that the isolation valves (if present) on the pipes leading to the radiator are fully open.
- Cold Spots on Radiator:
- This usually indicates trapped air. Bleed the radiator as described in the Operating Instructions.
- Water Leaks:
- Immediately turn off the water supply to the radiator if possible.
- Identify the source of the leak (e.g., pipe connection, valve).
- Tighten connections or replace faulty components. If unsure, contact a qualified plumber.
- Low Heat Output:
- Ensure the thermostatic valve is set to a higher temperature.
- Check the overall pressure of your central heating system.
- Bleed the radiator for air.
