Models: AVC6, FHM3, VSS-50 and HSS1-xx
1b. Install FHM3 Module
Install the FHM3 into a single-
gang electrical box located on
the front of the fume hood. Be
sure to select a location that
provides unobstructed access
for the user and is clearly
visible so the display can be
easily viewed.
If the fume hood does
not have a preinstalled
electrical box available,
then one will need to be
installed.
1c. Install Sash Sensors
Vertical Sash Sensor (VSS): Select a suitable location to attach
the retractable cable to the fume hood sash or counterweight
system per the VSS-50 Installation Drawing.
CAUTION: Do not allow the wire rope to "snap back" into the
reel or damage to the part or personal injury can result.
After securing the VSS to the fume hood and attaching the
retractable cable, verify operation by slowly raising and lowering
the sash while observing the VSS and retractable cable to ensure
the wire rope extends and retracts straight and without
interference.
Horizontal Sash Sensor System: Install the Panel Magnets and
HSS onto the fume hood per the instructions provided in the
Manual. Use the HSSK Horizontal Sash Kit to manage the cables
to prevent them from getting damaged. Due to variations in fume
hood construction, custom brackets may be required.
STEP 2: WIRING
Connections to the AVC6 Control Module will vary depending on
the application requirements. The below diagram is provided as a
general reference only. For detailed wiring requirements, refer to
the job specific submittal wiring diagrams and AVC6 Manual.
