5. Installation

Proper installation is crucial for the optimal performance of your thermostatic valve set. Follow these general guidelines:

1. Prepare the System: Ensure the heating system is turned off, depressurized, and completely drained before beginning installation.
2. Remove Old Valve (if applicable): Carefully remove any existing radiator valve, ensuring no water spillage.
3. Pipe Compatibility: This valve is suitable for Φ15 mm copper pipes and Φ16 mm multilayer composite pipes. If using Φ15 mm copper pipes, contact EMKE for the appropriate metal adapter.
4. Connect the Valve: Attach the multiblock valve to the radiator and the heating pipes. Ensure all connections are tight and sealed to prevent leaks. The valve supports connections for pipes coming from the floor or the wall.
5. Install Thermostatic Head: Once the valve body is securely installed, attach the thermostatic head by aligning it and tightening the retaining ring.
6. Refill and Bleed: After installation, refill the heating system, bleed any air from the radiators, and check for leaks.

6. Operation

The thermostatic head allows for easy and precise temperature control in the room. It features 7 adjustable settings to regulate the heat output of your radiator.

1. Adjusting Temperature: Rotate the thermostatic head to select your desired temperature setting. The head is marked with numbers or symbols corresponding to different temperature ranges.
2. Temperature Settings: The 7 adjustable settings typically correspond to specific temperature ranges. Refer to the diagram below for common settings.
3. Frost Protection: The '*' (snowflake) setting usually activates a frost protection mode, maintaining a minimum temperature (e.g., 7°C) to prevent pipes from freezing.

Figure 6.1: The thermostatic head with its adjustable settings. The table below the image shows the typical temperature ranges for each setting: '*' for 7°C (frost protection), '1' for 12°C, '2' for 14°C, '3' for 20°C, '4' for 24°C, and '5' for 28°C.

7. Maintenance

The EMKE Thermostatic Radiator Valve Set requires minimal maintenance to ensure long-lasting performance.

• Cleaning: Clean the exterior of the valve and thermostatic head with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the finish.
• Regular Checks: Periodically check for any signs of leaks around the connections. Address any leaks immediately.
• Valve Movement: If the valve is not used for extended periods (e.g., during summer), it is advisable to turn the thermostatic head through its full range of motion a few times a year to prevent the valve pin from sticking.

8. Troubleshooting

If you encounter issues with your thermostatic radiator valve, consider the following common problems and solutions:

• Radiator Not Heating:
  • Check if the thermostatic head is set to a sufficiently high temperature.
  • Ensure the heating system is operational and the boiler is functioning correctly.
  • Bleed the radiator to remove any trapped air.
  • The valve pin might be stuck. Remove the thermostatic head and gently press the pin to ensure it moves freely.
• Radiator Too Hot/Cold:
  • Adjust the thermostatic head to a different setting.
  • Ensure the thermostatic head is not covered by curtains or furniture, which can affect its temperature sensing.
• Leaks Around Connections:
  • Tighten the connection nuts.
  • If tightening does not resolve the issue, the seals may need to be replaced.

If these steps do not resolve the issue, please contact EMKE customer support for further assistance.
