1. Product Overview
The Caleffi Model 323-547-060 is a robust air separator designed for use in heating and cooling systems. Its primary function is to efficiently remove air and other non-condensable gases from the system fluid, thereby preventing issues such as noise, corrosion, and reduced heat transfer efficiency. This model features a durable cast iron body and female threaded connections for secure integration into piping.

2. Installation Instructions
Proper installation is crucial for the optimal performance of the Caleffi air separator. It is recommended that installation be performed by a qualified professional in accordance with local codes and regulations.
- System Preparation: Ensure the heating or cooling system is depressurized and drained before beginning installation.
- Location: Install the air separator at the hottest point in the system (typically the supply line leaving the boiler or chiller) where air solubility is lowest, allowing for maximum air release.
- Orientation: The air separator must be installed vertically with the air vent connection at the top. Ensure sufficient clearance for maintenance and operation of the automatic air vent.
- Connections: Use appropriate sealing compounds (e.g., PTFE tape or pipe sealant) on the female threaded connections to ensure a leak-tight seal. Do not overtighten.
- Automatic Air Vent: Connect an automatic air vent to the top port of the air separator. Ensure the vent is installed correctly and its cap is loosened to allow air release.
- System Refill: After installation, slowly refill the system, allowing air to escape through the automatic air vent. Monitor system pressure.
- Leak Check: Thoroughly inspect all connections for leaks once the system is repressurized.
Safety Precaution: Always wear appropriate personal protective equipment (PPE) during installation. Be aware of hot surfaces and pressurized fluids in operational systems.
3. Operating Principles
The Caleffi air separator operates on a simple yet effective principle. As system fluid containing air bubbles enters the separator, the internal design (often involving a mesh or baffle) creates a low-velocity zone. This reduction in velocity allows the smaller, lighter air bubbles to coalesce into larger bubbles and rise to the top of the separator. From there, the accumulated air is discharged through an automatic air vent connected to the top port, preventing it from recirculating throughout the system. The degassed fluid then continues its path through the system.
4. Maintenance
The Caleffi air separator is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended to ensure continued optimal performance:
- Automatic Air Vent Check: Periodically inspect the automatic air vent connected to the separator. Ensure its cap is loose (if applicable) and that it is not clogged or leaking. If the vent is not releasing air or is continuously leaking water, it may need cleaning or replacement.
- Visual Inspection: Annually inspect the air separator body and connections for any signs of corrosion, leaks, or physical damage. Address any issues promptly.
- System Water Quality: Maintaining good system water quality (e.g., proper pH, inhibitors) will extend the life of all system components, including the air separator.
