Operating the Vertical-Rising
Sash
Because of the Protector XStream Hood counterbalanced 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 to a maximum 28" operating height. The
airflow requirements should be sized for the 28" operating height;
if using sash stops provided at 18", then the airflow requirements
can be reduced by approximately 40%.
Operating the A-Style
Combination Sash
Optional hood models have sashes called A-Style Combination
Sashes in place of vertical-rising sashes. These combination
sashes allow the operator to use the hood with sashes either half
open horizontally or vertically to conserve energy. The horizontal
sashes are used in normal operating mode. Optional sets of sash
stops can be installed to prevent raising the vertical sash above the
half-open and fully closed positions unless manually defeated by
the operator. The airflow requirements are sized for the 50% open
sash condition.
