Fridge freezer advice

pondskater_2

We had a new fridge freezer delivered today. The delivery guy mentioned the four hour delay but I was not listening properly and misunderstood and thought he meant it would be ready to fill after four hours - I have just read the instructions and yes I should have let it stand without plugging in for four hours:eek: It has been running for about five hours now and seems ok but what damage will this have done and would unplugging and leaving it for a while be of any use.
Can any one help/advise?
