Jon,
Ever look at how steep 10 degrees is?
It equates to 2-1/8 inches per foot - that like taking a 24" wide condenser unit setting on a level pad and sliding a 4x4 (3-1/2") with a 1x4 (3/4") on of it (total height of 4-1/4") in under one side, tipping the condenser unit over far enough to slide that in.
That one photo looks like the condenser unit is setting on an upside down flotation device (Styrofoam beads and concrete = little weight) and, at most, it looks to be, at most, maybe 1" in 12" slope.
