PART 3 - EXECUTION

3.1 ROLLER SHADE INSTALLATION

A. Install roller shades level, plumb, and aligned with adjacent units according to manufacturer's written instructions. Allow clearances for window operation hardware.

12 24 12 - 5

B. Shades must be installed in shade recess pockets or on wood or metal plates. Shades must follow the slope of cab glass as closely as practical within physical limitations of air ducts and other equipment. No drilling must be done in vertical uprights of cab because some uprights may contain electrical cables.

C. Installer must inspect shades prior to installation. Shades must be cut to fit by manufacturer. Do not remove existing shades until new shades are ready to be installed. Shades that show evidence of damage or improper quality cuts will not be accepted by the FAA.

D. Spring tension in roller must be manually adjusted so that shades roll comfortably and do not bind.

E. In order to safely control and limit the shade travel, the installer must make two knots in the shade cord. One knot must be placed before the lock pulley to prevent the metal hemline bar from hitting the windowsill. The second know must be placed after the lock pulley to prevent the metal hemline bar from hitting and overrunning the shade roller. Adherence to THIS END UP label when installing shade will prevent improper roller installation which can result in a locked shade situation when the metal bar hemline is near the lock pulley and cannot be pulled down to release the spring motor cam lock.

F. Shade must be able to operate at a moment’s notice; to gain unimpeded rapid access for the use of emergency light guns. The inability for one controller to “snap-up” the shade in an emergency endangers lives, and system that does not meet the unimpeded rapid access will not be approved.

G. Adjust and balance roller shades to operate smoothly, easily, safely, and free from binding or malfunction throughout entire operational range.

H. Installed shades must hang flat without wrinkles or puckers. Adjust metal hemline bar to remove wrinkles and/or puckers as necessary.

I. Clean roller shade surfaces after installation, according to manufacturer's written instructions.
