How to transport a refrigerator or freezer and how and why to wait before running it
Refrigerators and freezers, along with the motor of air conditioners and tumble dryers with a heat pump, are products to which particular attention must be given during transportation.
Being characterised by the presence of a refrigerant circuit and a motor (otherwise known as a compressor), within which the refrigerant gas and oil required for their operation are found, the transport position most suitable is the vertical one.
The reason why you must wait some time, after transportation, before turning on the appliance, depends on the movement of the (refrigerant compressor) lubricating oil. When the appliance is transported in the horizontal position, the oil, which is located in the motor (compressor), moves, this results in it ending up in the refrigerant circuit in which it is mixed with the refrigerant gas. During the wait time, in the vertical position, the oil is made to return to the compressor. If you switch on the appliance immediately after the transportation and the oil is not found in the compressor, you will run the risk of causing the piston to seizure as it will not be lubricated.
When purchasing one of these products you will find yourself faced with two situations, the first is that home delivery by a courier is advised, the second is that that you yourself transport the product. In any case you need to know in what conditions the transportation was carried out.
In the first case the courier should inform you how the product has been transported. If it took place in the vertical position, after cleaning the appliance, it can immediately be switched on. If instead it was led down horizontallty, it is better to leave it in the vertical position for at least the same time during which it remained in a horizontal position. In any case, in order to to be safe and not to run a risk, it is best to put it in motion after leaving it vertically for 12 hours.
In the second case the situation does not change, you can only be certain, since you transported it yourself, whether this took place vertically or horizontally. In the former case, after cleaning it, you can start it up right away, in the second case it is best to wait 12 hours.
When it is moved horizontally make sure to place it on one side and not on the back or front to prevent damage to the refrigerator or freezer. Clearly, if led on the front it can be dented, while on the back you risk breaking the condensor and causing the leakage of the refrigerant gas. Avoid transporting the appliance by placing it in the upside down position.
