Operating the Vertical-Rising Glass Sash
Because of the Protector Perchloric Acid Hood’s 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 glass sash is suitable for use with Perchloric acid.
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 then the airflow requirements can be reduced by approximately 40% at 18"
or approximately 50% at 15".
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. Simply turn the light switch to “ON” to operate.
Operating the Washdown Control Valve
Your Protector Perchloric Acid Fume Hood has a washdown control valve located
on the upper left-hand side that controls water to the washdown spray nozzles.
The nozzles are located behind the hood baffle and will washdown areas in the
hood, which are unaccessible without removing the baffle. The washdown control
system can also be set up to control the washdown rings used in your exhaust
