Important Maintenance & Installation Warning

For your safety and to prevent water spills, the manufacturer strongly advises: Always ensure you cut off the power supply and close the water source/valves to the filter bucket before opening the canister to replace the filter cotton.

Rinse the new filter pads lightly with dechlorinated water or aquarium water before placing them into the filter baskets.
