UniTrak sensor.
a. Raise and lower the sash.
b. If necessary, re-align the strip so that the
actuator block travels evenly along the
center of the sensor strip, and that it does
not bind.
NOTE: If the mounting block linkage is
improperly bent, the tension on the
linkage, after being affixed to the
sash, may cause the linkage to pull
the mounting block from the sash.
7. Press the UniTrak sensor strip firmly to the fume
hood.
8. Press the mounting block firmly to the sash
panel.
9. If you are mounting to a metal sash frame. To
reinforce the adhesive, secure the block to the

NOTE: Be sure that the sash glass is not
encased in the frame in the area
where the screws will be attached. If
in doubt, do not drill into the sash
frame.

Section 5: Wiring
Outside sash UniTrak mount:
1. Locate a position on the fume hood to mount the
sensor connector.
2. Plug the sensor connector into the connector on
the end of the wires leading from the UniTrak
strip.
3. Route the sensor and attached wiring so that
when the vertical sash is moved up and down
the wires will not interfere with the sash
movement.
