Bending Linkages (Horizontal)
NOTE: If more than one UniTrak is mounted on the
fume hood, repeat the following steps for
each UniTrak.
Bends will reduce overall length by 1/2 inch
to 1-1/2 inches.
A 45-degree angle will clear most obstacles.
1. Estimate the mounting position of the linkage
(approximately 1 inch from the top edge of the
sash) (Figure 16).

2. Using the permanent marker, mark the linkage
where it is even with the UniTrak
actuator car.
3. Measure the distance from the edge of the sash
frame to the far edge of the actuator car = X
(Figure 17 and Figure 18).

4. Add 1/8 inch to X.
5. Using the 1/8 inch + X value, measure from the
first actuator car mark toward the mounting
plate, mark this location (Figure 19).
