Product Description

The UniTrak



Vertical Sash kit contains the

hardware for one fume hood sash. Fume hoods with

multiple vertical sashes, including walk-in fume

hoods, require multiple UniTrak



kits.

The kit consists of one adhesive-backed UniTrak



sensor strip with one sensor strip actuator attached,

one sensor connector with adhesive back, two

unbent linkages, and mounting hardware. See

Figure 1.

Actuator materials: polyvinyl chloride (PVC) and

stainless steel.

Sensor strip materials: polyester.

NOTE:

Fume hoods may have dimensional

variations; however, these variations will

have minimal impact on UniTrak

Affix the connector to the fume hood so that there is no tension and minimal slack on the sensor and its attached wires. 6. Route the sensor wires between the fume hood and the bottom of the airfoil, and to the controller. 7. Secure the wires with the wire tie mounts and nylon wire ties.
