How do I properly prepare the ice maker when first setting up the refrigerator?

Let the refrigerator operate for at least 24 hours first to ensure optimal performance. Then dispense the first 4 to 6 ice cubes into a glass, wait another 8 hours and dispense another 4 to 6 cubes, then wait 16 more hours before dispensing the first full glass of ice. After a power failure, empty the ice bucket so it can refill with fresh, loose ice cubes. (Page 63)
