Introducció
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your IMI Pneumatex Statico SD expansion vessel. Please read these instructions carefully before installation and retain them for future reference. Proper installation and maintenance are crucial for the longevity and optimal performance of the unit.
Informació de seguretat
- Installation must be performed by a qualified professional in accordance with local regulations and standards.
- Ensure the system is depressurized and cooled before attempting any installation or maintenance.
- No supereu la pressió màxima de funcionament de 3 bar.
- Utilitzeu l'equip de protecció individual (EPI) adequat durant la instal·lació i el manteniment.
- The expansion vessel contains pressurized gas. Do not attempt to open or modify the vessel.
- Regularly check the pre-charge pressure as specified in the maintenance section.
Producte acabatview
The IMI Pneumatex Statico SD is a diaphragm expansion vessel designed for use in closed heating and cooling systems. Its primary function is to absorb the volume changes of the system fluid caused by temperature fluctuations, thereby maintaining system pressure within acceptable limits. This model has a capacity of 50 liters and a maximum operating pressure of 3 bar.

Configuració i instal·lació
- Ubicació: Install the expansion vessel in an easily accessible location, preferably on the suction side of the circulation pump, where the system pressure is most stable. Ensure adequate space for future maintenance.
- Muntatge: The vessel can be wall-mounted using appropriate brackets (not included) or placed on a stable surface. Ensure the mounting is secure enough to support the vessel's weight when full.
- Comprovació de la pressió de precàrrega: Before connecting, verify the pre-charge pressure of the vessel using a pressure gauge. Adjust the pressure if necessary to match the system's static head pressure plus a small margin (typically 0.2-0.3 bar). The factory pre-charge is typically 1.5 bar, but this should be confirmed and adjusted for your specific system.
- Connexió: Connect the vessel to the heating system using the 3/4 inch threaded connection. Use appropriate sealing materials (e.g., PTFE tape or hemp) to ensure a watertight connection. A shut-off valve and drain valve should be installed between the system and the expansion vessel to facilitate maintenance without draining the entire system.
- Ompliment del sistema: After connecting the vessel, fill the heating system with water and vent all air. Gradually increase the system pressure to the desired operating pressure.
- Comprovació de fuites: Inspeccioneu totes les connexions per detectar fuites un cop el sistema estigui pressuritzat.
Instruccions de funcionament
Once properly installed and the system is filled and pressurized, the IMI Pneumatex Statico SD expansion vessel operates automatically. It will absorb the expansion of the heating fluid as the system heats up and release the fluid back into the system as it cools down, thereby maintaining a stable system pressure.
- Monitor the system pressure gauge regularly to ensure it remains within the recommended operating range for your heating system.
- Unusual pressure fluctuations may indicate a need for maintenance or troubleshooting.
Manteniment
Regular maintenance ensures the optimal performance and extends the lifespan of your expansion vessel. It is recommended to perform these checks annually.
- Check Pre-charge Pressure:
- Isolate the expansion vessel from the heating system using the shut-off valve.
- Drain the water from the vessel using the drain valve.
- Connect a pressure gauge to the air valve on the top of the vessel.
- Verify the pre-charge pressure. If it is below the required level (typically 0.2-0.3 bar above static head), repressurize the vessel using an air pump or compressor.
- Once the correct pressure is achieved, close the air valve, open the shut-off valve, and repressurize the heating system.
- Inspecció visual: Check the vessel for any signs of corrosion, damage, or leaks.
- Integritat de la connexió: Ensure all connections are tight and free from leaks.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| System pressure fluctuates excessively | Incorrect pre-charge pressure, damaged diaphragm, undersized vessel | Check and adjust pre-charge pressure. If diaphragm is damaged, replace vessel. Consult a professional for sizing. |
| Constant pressure relief valve discharge | Over-pressurization, faulty expansion vessel, incorrect pre-charge | Check and adjust pre-charge pressure. Inspect vessel for damage. Verify system operating pressure. |
| Water leaking from air valve | Diafragma danyat | The vessel diaphragm is compromised. The expansion vessel needs to be replaced. |
