Definitions
            IG units: insulated glass unit
Procedure

1. Use the lines capillary tube bending jig to properly bend the capillary tube.
   1. Do not attempt to bend a tube without the jig.
   2. Capillary tubes that are bent incorrectly can be ripped out by the sealer head, protrude too far into the IG unit, or not extended far enough into the unit.
2. With a center punch tool, puncture the spacer at the top corner.
   1. Make sure no spacer is left hanging or sticks to the inside of the unit when puncturing it.
3. Insert the capillary tube into the puncture in the spacer.
4. Visually check the inserted end of the capillary tube. Make sure nothing is clogging the end of the capillary tube and that it does not extend more than ¼” pass the spacer.
   1. If something is clogging the end, dislodge it before continuing.
   2. A clogged capillary tube cannot breathe and can cause the unit to fail when it attempts to pressurize to its destination.
5. Tape the exterior portion of the capillary tube to the glass.

After the unit has been sealed with hotmelt.

6. For patio units, remove the tape and run the capillary tube down the side of the IG unit.
   1. Be sure not to pull the capillary tube out during this process.
