How long should one wait after mission equipment power down before turning off the ECS Draw Thru?

Waiting 10 minutes after mission equipment power down before turning off the ECS Draw Thru is important for several reasons related to system cooling and equipment safety. When mission equipment is powered down, there can still be residual heat generated by components that were in operation. The ECS (Environmental Control System) Draw Thru helps to ensure that this heat dissipates adequately.

If the ECS Draw Thru is turned off too soon, heat may not be adequately managed, potentially leading to overheating of sensitive components, which can affect their performance or lifespan. Additionally, allowing a proper cooling period helps to stabilize the internal temperatures of the equipment and ensures that it is safe for handling. This practice helps maintain the integrity of both the mission equipment and the environment in which it operates, safeguarding both personnel and the hardware from potential thermal damage.

A 10-minute wait provides a balance between allowing enough cooling time while not delaying operations unnecessarily.
