Avoid absorbing liquids into the pump. Stop the vacuum sealing process immediately if you notice any liquids being sucked towards the pump. If liquid does accidentally enter the pump, turn the pump off and shake it lightly. If you have sucked in so much liquid that you are unable to turn the pump on again, proceed as follows: lightly shake the pump to clear the liquid. Do not turn it on its head! Ensure that the pump and charging station are completely dry. Then connect the pump to the charging station for 1 second to reset it. Separate the pump from the charging station and press the ON/OFF button. If the pump continues to turn itself off, repeat this process.
