Chapter 5: Using Your Protector Perchloric Acid Fume Hood
Operating the A-Style
Combination Sash
Optional hood models have additional energy saving
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 Perchloric Acid 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 Perchloric Acid 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 ductwork. This is done by
