This sampler has a high performance pump. As with all such
pumps, it relies upon liquid to cool working components. If the
sampler is programmed to pump in the absence of liquid in
excess of 5 minutes, excessive heat buildup may damage the
paddles, rollers, and housing. Ensure that the liquid inlet is
completely immersed.
