Operating the Vertical
Rising Sash
Because of the Protector ClassMate's counterbalanced,
anti-racking sash mechanism, it will take only a few
pounds of force to move the sash up or down, and you
can operate the sash smoothly with one or two hands
positioned any where along the handle. The vertical
rising sash may be raised from a closed to 18" operating
height where it bumps the sash stop. (See Figure 5-1)
For loading and cleaning, the sash moves up past the
sash stop; however, please note that the airflow
requirements are sized for the 18" operating height.
