Query: SPT SF-608R Air Cooler

I bought this air cooler thinking I could save some money over an air conditioner, I started reading the instructions (I know your suppose to wait it I've hosed it up before reading the Instructions), it tells me I need 6 liters of water and 2 liters of ice, now I'm seeing the light, after 6 or 7 trips to fill the cooler, I turned it on, it felt somewhat cool, so I waited, took a hour long walk, the room was just barely cooler. Maybe if I had the time to keep it filled, and run it for a week or more, the room might have been a few degrees cooler. I put it in storage.
