Mounting Plate Installation without an
Existing Cutout
Use one of the following methods:
Using a drill
or
Using a metal-cutting saw
for cutting the mounting
hole depending on the tools available.
Using a drill:
1. See Figure 8. Use this diagram to locate the
holes from the
corner of the case
. Do not use
the corner of the mounting plate as the
reference point. Mark the locations on the fume
hood.
2. See Figure 4. Using the mounting plate as a
template, mark the locations of the two mounting
holes.
3. Drill the required holes using the locations and
sizes shown in Figure 8.
NOTE:
If FLN or AUX connections are not
required for installation, then only
drill holes for the air tube and power.
4. Using a 1/8-inch (3.0 mm) bit, drill the two
mounting holes.
5. Using the screws provided, attach the mounting
plate to the mounting surface.
Using a metal-cutting saw:
1. See Figure 9. Use this diagram to locate the
rectangular cutout from the
corner of the case
.
Do not use the corner of the mounting plate as
the reference point.
2. Using the mounting plate as a template, mark
the locations of the two mounting holes and the
2 inch
×
3 inch (5.0
×
8.0 cm) cutout.
See Figure 4.
Figure 4. Installation without an Existing Cutout.
3. Using a metal-cutting saw or other suitable tool,
remove the marked rectangular area.
4. Using a 1/8-inch (3.0 mm) bit, drill the two
mounting holes.
5. Using the screws provided, attach the mounting
plate to the mounting surface.
6. Proceed
to
Sidewall Hose Mounting
.
Sidewall Hose Mounting:
NOTE:
The location of the sidewall adapter greatly
affects the performance of the Fume Hood
Monitor. Use the
FHM Hood Evaluation
Kit
, part number 546-00320, to accurately
determine the location for the sidewall
adapter.
1. Mark the location of the hole for the air sensor
hose 3 inches (7.5 cm) above the highest sash
opening and 6 to 8 inches (15.0 to 20.0 cm)
back from the sash track.
NOTE:
The hole location for the air sensor
may vary slightly due to hood
construction.
On fume hoods with a
mechanical stop,
do not
use the
mechanical stop as a reference
point. Use the highest possible open
position of the sash as the reference
point.
2. At the mark found in step 1, drill a 1/2- inch
(13.0 mm) hole in the sidewall of the fume hood.
CAUTION:
If the construction of the fume hood
contains fiber-cement panels, then use
diamond core drill bits to drill holes inside
the fume hood. Fiber-cement panels are
used for impact, moisture, and fire
resistant applications. Diamond core drill
bits are designed for hard and abrasive
materials. Standard drill bits may crack and
damage fiber-cement panels.
