Forum » PRIME 30 - NEED HELP

Hello, I bought a filter Prime 30,I'm having problems with the installation and mounting it in aquarium. I did all the procedures described in the manual. When I turn on the filter, he begins to work, apparently normal, it pulls water from the aquarium into the filter, however, when the filter is full of water and start to filter returning the water to the aquarium, the filter gets off and disarms. It seems to me that the filter "drowns. " I´m sending attached pictures. I took for you to solve my doubts. 1 - Am I doing something wrong? 2 - There is a grey sticker pasted on top of a party to the filter, which covers a hole. Should I leave the sticker pasted or retreat? Thanks,
