Long Term Storage Instructions

3. Fill the dirty water bag with safe water to the max line and add 1/2 teaspoon of household bleach. Close the cap and shake the bag a few times to mix well.
4. Connect the hose to the filter, hang the gravity system, and twist to allow water to flow through the filter until the gravity bag is empty.
5. Disconnect the filter and keep it vertical for a few moments until no water runs out. Do not shake the filter.
6. Twist to close the membrane ultrafilter cartridge, keep the hose attached to the filter, and roll it around.
7. Allow the dirty water gravity bag to dry naturally by leaving the cap removed.
8. Store in a cool, clean place.

Before Using Again
