Operating the Vertical-Rising Sash
Because of the Protector 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 sashes may be raised to a maximum 28" operating height. The
airflow requirements should be sized for the 28" operating height; if using sash
stops then the airflow requirements can be reduced by approximately 40% at 18".
See
Chapter 2
for airflows.
Operating the Blower
Your Protector 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.
Operating the Lights
Your Protector Fume Hood utilizes a factory-wired fluorescent light to illuminate
the hood interior. Optional direct replacement LED T8 bulbs are available per
Appendix A. Simply turn the light switch to “ON” to operate.
