Answers:    In the coils and compressor is where the coolant and the grease that circulates through the coolant lines collects. It needs to be at the bottom when the compressor is turned on, so if you tip it over, you gotta depart from it upright for 24 hours previously plugging it in or you might wear out the compressor.
If you transport it standing up, the grease is left surrounded by the right place for it to be turned on as soon as you move the freezer into position when unloading it from the truck.
There is gas in the freezer which requirements to be settled before use. Same near a fridge. If item is tipped , it needs to stand for a while up to that time turning on.
