BLOWER VACUUM SWITCH | IDXL2BVS1930

The Hayward Blower Vacuum Switch (IDXL2BVS1930) detects the vacuum pressure generated by the blower motor in your pool heater. This pressure is essential for proper airflow and combustion. 

• Blower Creates Vacuum Pressure:
• The blower motor generates a vacuum that helps move air and combustion gases through the heater. Proper airflow ensures safe and efficient combustion of gas.
• Vacuum Pressure Detection:
• The vacuum switch monitors the pressure created by the blower motor. It’s calibrated to detect the correct range of vacuum that indicates proper airflow.
• Ensuring Safe Operation:
• If the vacuum pressure is too low (indicating an airflow issue, like a blocked blower or vent), the switch prevents ignition by sending a signal to the heater’s control system.
• This prevents the heater from turning on, ensuring there are no risks of overheating, improper combustion, or other unsafe conditions.
• Interruption of Ignition:
• If there is a problem with airflow, the switch acts as a safety interlock to stop the heater from igniting. This safeguards the system from operating without the necessary air pressure, preventing possible damage.
