Maintenance Tips
-
Inspect the automatic air vent regularly to ensure efficient air removal from the system.
-
Check NPT connections for tightness and signs of leakage to maintain optimal performance.
-
Monitor system pressure for early signs of trapped air that may reduce efficiency or circulation.
-
Flush and clean the separator during routine system servicing to remove sediment or buildup.
-
Schedule professional maintenance if air remains in the system or performance declines.
