1. Cut tube within 1⁄2” from end with wire cutters.Cutting the tube actually closes the end.
  2. Apply a dab of silicone sealant at the end of the capillary tube after it has been cut.
  3. The IG unit must always be installed with the capillary tube pointing down along a vertical edge.


Important Notes

  1. Do not push or pull the capillary tube as this will loosen it, creating a path for moisture to enter the IG unit.
  2. Allow units to equalize pressure by resting in a vertical position at the jobsite elevation for a minimum of 72 hours or until the lites are essentially flat.
  3. Closing the tubes over a wide range of temperatures, or during extreme low or high temperatures may result in IG units having varying degrees of flatness.
  4. Failure to follow these instructions will void the IG warranty.
