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%. See Chapter 2 for airflows. Optional models with auto-
return to 18" or electric Intelli-Sash are available.
Operating the A-Style Combination Sash
Some other 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.
Operating the Blower
Your Protector XStream Fume Hood utilizes a remote style blower, which can be
activated by turning the blower switch to “ON.” You can validate the hood
performance by watching smoke drawn into the hood face opening.
