Maintenance Tips
-
Inspect for Leaks – Regularly check the trap for steam or fluid leaks around the connections to ensure a secure seal.
-
Clean the Strainer – Periodically remove the strainer to clean debris and dirt that could block the flow and reduce efficiency.
-
Check the Thermic Bucket – Inspect the inverted thermic bucket for proper operation, ensuring it moves freely and doesn’t have signs of corrosion or wear.
-
Monitor Pressure – Ensure the trap operates within the 20 PSI rating to avoid over-pressurization and prevent damage.
-
Verify the Orifice – Check the 3/16-inch orifice for any obstructions that could hinder steam or fluid flow.
-
Ensure Proper Drainage – Confirm that the trap’s drainage is functioning correctly to prevent water accumulation and maintain efficient operation.
-
Annual Professional Inspection – Have a technician inspect the trap annually to ensure it's functioning properly and to address any potential issues.
