Important: Handling & Care

This type of pump cannot be left submerged for extended periods of time.

Remember to remove the pump from water after you’re done with the project and dry it as best as possible with a paper towel. Do not put the pump and water tubing away while they are wet; let them finish air drying before putting them back into the Climate Action Kit with the other components that are sensitive to water.
