To Insert:
Hold down the RELEASE button under the lid while lowering the reservoir down into place, directing the nozzle through the drain opening. Let go of the RELEASE button when the reservoir is securely and completely in place.
To Remove:
With your infusion completely drained, press and hold down the RELEASE button under the lid while lifting the reservoir UP and out of the LEVO.
Note: Pressing the RELEASE button once will open the drain valve for 7 seconds; or you can press and hold for as long as necessary to insert or remove the reservoir.
