Lift the protective cap on the inflation valve, located on the end of the bed.
Locate the deflate port on the pump. The deflate port is located on the top of the pump and runs perpendicular to the inflation port.
Insert the deflate port into the valve and then move the pump switch to the "On" position.
Allow the bed to deflate and then turn the pump to the "Off" position.
Roll the bed, starting at the opposite side of the valve, toward the valve, to further deflate the bed.
Replace the valve cover when the bed is completely rolled.
