VENT MAINTENANCE
TYCO Oxygen Removal Vents (TAV-D / TSV-D) Maintenance Instructions
1. TAV-D Vent - The TYCO TAV-D Vents must be inspected annually at minimum. While isolation ball valve is in the open position, check for air/water leaks and ensure the pressure gauge is displaying normal system pressure.
2. TSV-D SMART Vent - The TYCO TSV-D Vents must be inspected annually at minimum. While isolation ball valve is in the open position and the VENT button is illuminated, check for air/water leaks and ensure the pressure gauge is displaying normal system pressure.
3. TAV-D / TSV-D Vents - While isolation ball valve is in the closed position the inspection must include the condition of the in-line filter, and blockage in the “Y” strainer and restricted venting orifice. Depressurize the in-line filter housing by pressing the pressure relief valve on the bottom of the housing. Twist the filter housing counter-clockwise until it can be removed to expose the filter element.
4. TAV-D / TSV-D Vents - The filter element in the in-line filter should be replaced if a visual inspection reveals a significant collection of debris.
