Sash
Operation
The Logic sash uses a deadweight-counterbalanced system. The system consists
of two separate weights on either side of the liner. Both weights are
synchronized by a locked axle-pulley system. Both pulleys are fixed to the axle so
that both weights must move together, preventing the sash from racking.
Adjustment
There are no adjustments for the width of the sash track. There should be
approximately 1/8-inch lateral play of the sash in its track. If there is no lateral
play, examine one or both of the corner posts to ensure that they are not bent
inward. If the sash becomes racked, or is closing unevenly, it can be aligned as
follows:
1. Close the sash completely, until the lower edge of the sash is contacting the
sash stop. If the other end of the sash is not resting on its sash stop,
CAREFULLY lift the counterweight on the “high” side of the sash. This will
allow the high side of the sash to lower to the sash stop, leveling the sash.
See Figure 8-5.
