What is the drip tray for?
Instructions don't mention placement it. Is it to go inside the fridge??
Kitchen-sized refrigerators have mechanisms to handle the frost that builds up on the side of the freezer areas.
This smaller unit does not have that ability.
The drip tray is for helping when you need to defrost the freezer (only necessary occasionally when the condensation builds up too much on the side of the freezer area). This is done by taking out the food, unplugging the unit, and then the ice melts and drips into the tray.
So you won't need it on a regular basis...only when you defrost the freezer. That's probably why they don't mention where it goes.
