air is drawn in and returned from the bottom surface in the images shown but the unit can be mounted in any orientation. If you side mount you will want the intake side to be on the high side. if you bottom mount you will have issues with warmer temperatures on the top than the bottom (and you might loose some food ;-)

Being able to use the existing lines and evaporator assembly is unlikely. However, it is certainly possible to use a thermosiphon and remote mount a module assembly (SC-UA04) but requires a fair portion of thermo and fluiddynamic engineering for stable operation at variable attitudes. You could also engineer a custom heat pipe solution with a little less effort but the cost may be prohibitive.
