⚠️ Common Faults Associated with the 4-Way Valve

Malfunctions of the 4-way valve can lead to several operational issues, often indicated by system alarms:

• Low-Pressure (LP) Alarms: May result from the valve failing to switch correctly, causing inadequate refrigerant flow and reduced system pressure.

• High-Pressure (HP) Alarms: Can occur if the valve sticks or leaks internally, leading to restricted refrigerant flow and elevated system pressure.

Regular maintenance and timely replacement of the valve are crucial to prevent these issues and ensure optimal heat pump performance.
