The freezer itself. It is removed and is being replaced. This is the shell where it would be housed.

I do not know. Possibly switching it from a freezer to a refrigerator? Or it could have broken down and is being replaced.

To the right you can see that with the unit installed, there are doors at each opening where you can grab items to purchase. There is a walk-in section in the middle to restock the freezers. This shows the walk-in area minus the freezers, so it's one big empty space.
