3. Installation

The installation of the IMI Heimeier Multilux Eclipse valve set requires specialized knowledge and should only be carried out by a certified heating engineer. This section provides a general overview of the installation process.

3.1 Pre-Installation Checks

• Verify that the valve set matches your heating system requirements.
• Ensure all necessary tools and materials are available.
• Confirm the heating system is drained and isolated.

3.2 Installation Steps

1. Prepare Connections: Ensure the radiator connections (R1/2, G3/4) and pipe spacing (HOH 50mm) are compatible with the valve set.
2. Mount Valve Body: Securely attach the under-counter valve body (Figure 2) to the radiator and heating pipes. Ensure correct orientation for straight or angular connection as required.
3. Connect Thermostatic Head: Mount the chrome thermostatic valve head (Figure 1) onto the valve body. Ensure it is securely fastened.
4. Fill and Vent System: Once installed, slowly refill the heating system and carefully vent all radiators and pipes to remove air.
5. Check for Leaks: Inspect all connections for any signs of leakage.

4. Operating Instructions

The IMI Heimeier Multilux Eclipse valve set allows for both temperature control and flow rate adjustment.

4.1 Temperature Control (Thermostatic Head)

The chrome thermostatic head (Figure 1) regulates the room temperature. Rotate the head to your desired setting:

• Setting '0' or '*': Frost protection setting. The valve will open only if the room temperature drops below approximately 6°C to prevent freezing.
• Settings 1-5 (or higher): These settings correspond to increasing room temperatures. A typical comfortable room temperature is often achieved around setting 3 (approximately 20°C). Adjust as needed for comfort.

4.2 Flow Control (Valve Body)

The white valve body (Figure 2) features a flow control mechanism, typically used for hydraulic balancing of the heating system. This adjustment is usually set during commissioning by a professional and should not be altered by the end-user without proper knowledge.

• The numbered scale (e.g., 2, 3, 4) on the knob corresponds to different flow rates.
• Consult your heating engineer for optimal flow control settings for your specific system.

5. Maintenance

Regular maintenance ensures the longevity and efficient operation of your valve set.

• Cleaning: Clean the exterior of the valve set with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the chrome finish.
• Leak Checks: Periodically inspect all connections for any signs of water leakage. Address any leaks immediately by tightening connections or replacing seals if necessary.
• Functionality Check: Occasionally rotate the thermostatic head through its full range to ensure it moves freely and is not stuck.

6. Troubleshooting

If you experience issues with your heating system related to the valve set, consider the following common problems and solutions:

For persistent issues, contact a qualified heating engineer.
