It is absolutely essential that you make sure that the window opening is plumb and square

	#1 It is absolutely essential that you make sure that the window opening is plumb and square. Then install operative side (unless otherwise specified, this is the left hand side). Screw firmly to jamb or mullion.

#2 Install non-operative side as near as possible to the operative side. Sart by putting two screws loosely in the top holes. This permits bottom of louvre frame to be moved in and out for accurate alignment.

	#3 Fit the blades starting at the top, then working down in sequence.

#4 Screw blades securly into place.

	#5 Close the louvres, then move the bottom of the non-operative side in and out of the non-operative side until all the louvres are uniform tight fit. When both sides are exactly parallel, fit the remainder of the screws to secure right-hand side.

#6 Check over the entire installation and operate the handle several times to ensure that the blades open and close smoothly
