How to Insert a TruSteel Infusion Set
1. Open packaging and remove the protective cap from the connector needle. Clean the insertion area with an alcohol prep pad or other recommended skin preparation.
2. Hold the connector needle at the point where it connects with the tubing and insert it into the coupling housing. You should hear a click.
3. To attach the infusion set tubing to the t:lock connector on the cartridge, twist the connector clockwise until tight, then twist another quarter of a turn to ensure a secure connection.
4. Fill your tubing according to the instructions detailed in the Tandem Diabetes Care insulin pump user guide. DO NOT fill tubing while the infusion set is connected to your body.
5. When filling the tubing, hold the steel needle pointing down. Make sure there is no air in the tubing. Stop after three drops of insulin have appeared from the needle.
6. While holding the retaining wings of the infusion set, carefully remove the backing paper under the needle.

11. Remove the backing paper from the coupling housing and attach it to a location that allows for easy access.
Note: Ensure that the tubing between the introducer needle and housing is not too tight.
