To Fill the Reservoir:

To Rewind the Piston in the Pump:

1.  Wash your hands. Remove the old infusion set  

  from your body and the reservoir from the pump.

2.  Select Prime in the  

     MAIN MENU. 

  Then select Rewind  

  to open the  

  REWIND screen.  

 Press 

ACT

 to rewind. 

1.  Remove the  

  reservoir from the  

 package. 

2.Pull the plunger down  

  to fill the reservoir with    

 air.

WARNING: 

If  

insulin, or any  

liquid, gets  

inside the tubing  

connector, it can  

temporarily block  

the vents that  

allow the pump  

to properly prime the infusion set. This may  

result in the delivery of too little or too much 

insulin, which can cause hypoglycemia or  

hyperglycemia. To prevent insulin from getting 

inside the Silhouette tubing connector, after you 

fill the reservoir make sure you hold the insulin 

vial upright when you remove the reservoir from 

the transfer guard. If you do not hold the insulin 

vial upright, insulin can get on the top of the 

reservoir and could transfer liquid into the tub-

ing connector.

4.  Push down on the  

  plunger to push air  

  from the reservoir  

  into the vial.  

  Continue to  

  hold the plunger 

 down. 

5.  Flip the vial over  

  so it is now on top.  

  Slowly pull the    

  plunger down to  

  fill the reservoir. 

6.  Check the 

  reservoir for air    

  bubbles. Tap the   

  side of the reservoir  

  to force any bubbles  

  to rise to the top.  

  Push the plunger  

  up to move the air bubbles from the reservoir  

  into the insulin vial.  

7.  After the air bubbles  

  are removed, slowly  

  pull the plunger   

  down to fill the    

  reservoir with enough    

  insulin to last 2-3 days. 

8.  To avoid getting insulin   

  on the top of the  

  reservoir, flip the vial  

  over, so the vial is  

  upright. Hold the  

  transfer guard, and turn   

  the reservoir counter-   

  clockwise. Pull the  

  reservoir straight up to    

  disconnect it from the transfer guard.  Discard  

  the transfer guard into a sharps container.

3.  Wipe the top of the  

  insulin vial with    

  alcohol. Hold the  

  blue transfer guard  

  and press it  

  down onto  

  the insulin vial.
