Set a large mug on the Keurig B60 drip tray.
Lift up the top lid and pull out the water reservoir. Rinse well with water and fill with clean water until just below the top edge.
Set the water reservoir back into the base, pushing down until the tabs lock into position. Close the lid.
Connect the power cord and press "Power." Wait for the display to show "Not Ready" and then press the "Small Mug" button.
Wait approximately four minutes for the water to heat in the unit. When "Ready" shows on the display, press the "Small Mug" button again. The water will dispense in the mug.
Empty out the water from the mug. The Keurig is now primed and ready for use.
