=== Recirculation Valve === | === Recirculation Valve === | ||
Adjustments to the recirculation valve require extreme care, especially when the main pump is operating. The butterfly valve has a tendency to pull itself closed rapidly if the operator is not careful. Such a rapid change in flow and pressure may cause significant damage to the system. | |||
When adjusting the recirculation valve, use the following precautions: | |||
* Ideally, turn off the main pump before adjusting. | |||
* If the main pump cannot be stopped, use two hands and extreme care in moving the valve position. Ensure the valve is locked into a notch before releasing the lever. | |||
* Adjust the position by no more than 1-2 notches in the open or closed direction. Observe changing in the operating parameters (i.e. boiler manifold temperature) before making additional adjustments. | |||
