Inside mounted sash sensors:
1. With the sash window fully closed, mark the
location of the bottom of the sash window with
the marker.
2. With the sash window fully open, mark the
location of the bottom of the sash window with
the marker.
3. Measure the length between the open and
closed marks. Add 2 inches (5 cm) to account
for over-travel.
4. Erase the marks on the fume hood by using
isopropyl alcohol and a soft cloth.

1. Compare the actual length of the sensor strip
with the required length of the sensor strip
determined in Section 1. 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). Rejoin the sensor wires. See Figure
2.
3. Use the alcohol towelette to clean the surface on
which the UniTrak

sensor is to be applied. Dry
the surface thoroughly before mounting the
UniTrak.
NOTE: If you apply the UniTrak

sensor
without pressure to the mounting
surface, you may remove and
reapply the sensor if necessary. If
pressure is applied, the sensor’s
adhesive backing may be damaged if
the sensor is removed. The sensor
will be applied firmly after the
linkage-mounting block is installed.
4. Remove the protective backing from the sensor
strip. Make sure the sensor connector is
positioned at the top of the sensor.
5. Be certain that there is a gap of least 3/8-inch
between the sensor strip and the sash panel.
6. When attaching the UniTrak

to the mounting
surface hold one end up and lightly place the
opposite end down. The UniTrak should be
mounted as straight (parallel to the sash) as
possible.
7. Locate the correct mounting area for the UniTrak
sensor. See Figure 3 and Figure 4.
8. Slide the actuator block to the bottom of the
UniTrak

sensor strip.
