Speed Control
The speed control should only be adjusted by a qualified service technician.
Adjusting the
airflow will affect the operation of your hood due to the critical balance required
. Remove
front snap cap located on the front panel to access the speed control. Use a flat headed
screwdriver to adjust speed, turning clockwise to increase speed. After adjustment of the
speed control, airflows should be checked to ensure it is within the specified range as
outlined in chart. Refer to IES standard IES-RP-CC-002.2.
10. Exhaust System Safety Pressure Switch
This switch is located inside the head section and is connected to the exhaust collar via
tubing. In the case of total or partial exhaust failure, this switch will turn off the supply fans,
ensuring no air will be blown out of the containment work zone. Supply fans will not run
unless tubing is connected.

The model number is located on the front panel in the lower right hand corner. The serial
number and electrical information is also included on this label. Refer to these numbers
when contacting the manufacturer.

The Total Exhaust Hood uses 115-volt, 90-watt energy efficient motorized impellers to
provide excellent airflow distribution, quieter noise levels and low heat loads. Standard on
your Total Exhaust Hood is a FT2 type CSA approved 3-prong electrical cord. Always
unplug your hood when servicing.
13. Changing Sash Window Cables
Should the event of a sash cable replacement be required lift the window as high as
possible and support with two wooden studs cut to length. Remove the interior side panels
(LHS and RHS), remove the old cable and support the weight with a temporary 2” high
stand (this will compensate for stretching of the cable later). Attach new
c
’’ dia.
polypropylene rope, with a rating of at least 45lbs, to window end first. Thread through
pulleys and secure around weight eyelet with cable as tight as possible.
Always change both ropes at the same time. Consult factory for full rope specifications.
