You can't turn it that way, SuperQT. I asked my fiance who has a heat and air conditioning business, and he said that you can't do it. He went into a rant about oil in the motor, etc. Long story short, he said don't do it.
the worst that could happen is it probably won't work (they use water among other things to cool the air that i assume needs to be in a certain position for it to function properly).
