Do you need a water hookup for a fridge?

A water line allows you to make ice in your refrigerator. Refrigerators that feature built-in water dispensers or automatic ice makers need to be connected to a water source. Fridges without ice makers or water dispensers dont need any type of water source to function properly.

Do you have to let a freezer sit before plugging it in?

Let it stand Fridges and freezers are full of fluid thats used to cool the compartments. In transit, your appliance gets shaken around, so its best to let everything settle before you plug it in. If it was transported upright, give it at least an hour before you plug it in.
