Branch Duct Installation Procedure
1. Look for the yellow sticker on the casing for location of
branch duct or fresh air intake connections.

neath the casing insulation. Use a cutter and follow along
the pre-cut circular marking as shown and trim off the
insulation.
3. Knock out the pre-cut hole.

mm. tapping screws.
