Install a Linear Slot Diffuser
What you'll need
PencilDrillScrewdriver4 screws (included)
Six steps
1
Hold it level and mark the screw holes.
2
Four marks — two at each end.
3
Drill a small pilot hole at each mark.
4
Set the diffuser back over the holes.
5
Drive the four screws — snug, not tight.
6
Done. Turn the air back on.
Keep it level. Long slots show every tilt — get it level before you mark in step 1.
Questions
Do I really need to drill?
Yes — it mounts to the wall and needs four pilot holes so the screws hold and the wall doesn't crack.
Can I paint it first?
Yes. If you're painting, do it before you mount the diffuser.
Which way does the air go?
The slots set the throw. Aim it away from windows, toward the center of the room.
