Airflow Smoke Patterns
Non-thermal smoke should be released from one side of
the enclosure to the other, along a line in the middle of
the work area, two inches above the work surface. The
smoke should flow directly into the rear baffle. Smoke
released near the front end of the enclosure, or at the
top of the enclosure may exhibit vortexing and a reflux
along the sidewalls or top of the enclosure. This
turbulence is normal and does not negatively impact
containment of aerosols above the disposal hole.
Motorized Impeller
Replacement
The motorized impeller should be replaced by a
qualified certifier. The motorized impeller is a non-
serviceable component and must be replaced as a unit.
When the motorized impeller is replaced, its capacitor
should be replaced with a new one. Following
replacement of the motorized impeller, the cabinet
MUST be recertified by a qualified certifier.
1. Unplug the enclosure. Remove the post filter.
Remove the top panel by removing all of the
fasteners on the top as described in the
Customer Service Operations section of this
manual.
2. Disconnect the motor ground wire from the
frame. Disconnect the wires connecting the
motorized impeller to the wiring harness.
3. Using a small wrench, remove the four lock nuts
that secure the motor brace to the blower shelf.
Remove the brace and motorized impeller as an
assembly. Placing the assembly on a flat
surface, remove the four screws that secure the
motorized impeller to the brace. Disconnect the
two wires from the motor to its capacitor,
located on the side of the brace. Remove the
motorized impeller from the brace.
