Sash Weights
The sash weights have been secured to the shipping skid. Remove the weights from the
skid and attach them to the respective sash cables using the hooks provided.
With the sashes in place, install the counterbalance weights. The large single sash
weight is installed in the middle and attached to the lower rear sash. The two individual
sash weights counterbalance the front vertical-rising sash; these weights have rollers
and ride in the rear sash tracks that straddle the middle sheet metal sash weight. Install
the rear weight tracks for the individual sash weights with the #10-24 screws and #10-
24 KEPS nuts supplied. See Figures E-2 and E-3. It is important the front upper and
lower sash tracks are fully aligned. Use the strap plates to secure this alignment. Once
the sashes are aligned and operating freely, secure the lower base to the floor with
sealant or fasteners. (Note: Hardware not supplied due to installation variables.)
Securing the lower base will ensure the sashes will work freely.
Sash Stops
Install the four rubber bumpers with #6 screws supplied. One set of rubber bumpers
prevents the front upper sash from traveling too low. The second set of rubber bumpers
prevent the rear lower sash from touching the floor and provides a good sweep of clean
air across the floor. See Figure E-3.
Corner Post Installation
Locate the left and right corner posts on the third shipping skid. The edges on the
corner posts fit directly onto the side frames. The front inner edge of both corner posts
