Installation Instructions
August 10, 2004
Prerequisites
• If this is your first UniTrak installation, read these
instructions entirely before beginning.
• The fume hood sash panels must be installed to
ensure proper fit of the UniTrak sensor.
• For retrofit installations, notify the laboratory
safety officer that you will be working in the fume
hood. Take the necessary precautions to have
the fume hood cleaned, prepared and safety
certified.
WARNING:
Do not proceed with these installation
instructions until the fume hood has been
cleaned and emptied of all hazardous
substances including fumes, vapors, toxic
materials, contaminants, chemicals,
bacteria, etc.
The following prerequisites apply to Vertical:
• For best appearance, mount the UniTrak sensor
on the inside of the fume hood.
• The surface on which you mount the sensor strip
should be smooth, flat, clean, and free of
obstacles such as rivets, screw heads, nozzles,
sash stops, and abrasives.
• If corrosive fumes are to be exhausted, mount
the UniTrak sensor on the outside of the fume
hood.
Instructions
The UniTrak Sash Sensor Installation Instructions
consist of the following tasks. Tasks 3 and 5 for the
Vertical Install have separate instructions for outside
and inside mountings of the UniTrak sensor.
Tasks Horizontal Vertical
1 Measuring the Sash
Opening
N/A Step 1 (p. 3)
2 Mounting the UniTrak Step 1 (p. 5) Step 2 (p. 3)
3 Bending Linkages Step 2 (p. 8) Step 3 (p. 6)
4 Attaching Linkages to
Sash Panels
Step 3 (p. 10) Step 4 (p. 10)
5 Wiring Step 4 (p. 12) Step 5 (p. 11)
6 Installing the Sensor
Shield
Step 5 (p. 13) Step 6 (p. 13)
CAUTION:
Do not bend or kink the sensor strip, as
this will damage the sensor. Bends in the
sensor strip will cause errors in the sash
measurement.
Measuring the Sash Opening
(Vertical)
Outside- and inside-mounted sash sensors:
1. For outside-mounted sensors: Measure the
length of the mounting surface.
2. With the sash window fully closed, mark the
location of the bottom of the sash window with
the marker.
3. With the sash window fully open, mark the
location of the bottom of the sash window with
the marker.
4. Measure the length between the open and
closed marks. Add 2 inches (5 cm) to account
for over-travel.
NOTE: For outside mounting: This
measurement must not exceed the
mounting surface length from Step 1.
5. Erase the marks on the fume hood by using
isopropyl alcohol and a soft cloth.
Cutting and Mounting the UniTrak
(Vertical Only)
WARNING:
Do not cut horizontal sensors. Operation
of the second actuator car will be lost.
1. Compare the actual length of the sensor strip
with the required length of the sensor strip
determined in Measuring the Sash Opening. If
necessary, use the trim tool kit to cut the sensor
strip. Be sure that the sensor is face up. See
Figure 2. If you do not have to cut the sensor
strip, skip to Step 3.
2. Separate the two sensor wires and seal the cut
ends with the provided silicon (small, unmarked
white tube). See Figure 2.
