How Do I Find the Drainage Hole In the Back Of My Haier Air Conditioner?

My air conditioner was spitting and sputtering water into my room. I asked on this board and was advised to tilt it out, drain it, find the drainage hole and clean it out. When I tipped it out backwards, nothing happened. When I tipped it into the room, all the water spilled out and onto the floor. However, this seemed to solve the problem. I searched for the drainage hole, but could not find it. A few days later, the a/c unit was back to spitting cold water into my room. How do i resolve this? (I recently cleaned the filters)
