UniTrak Sensor Assembly Kit

Horizontal, Vertical, and Combination Sashes

Product Description

The UniTrak™ Sensor Assembly Kit contains the

hardware to complete one fume hood sensor

assembly. Fume hoods with multiple vertical sashes,

including walk-in fume hoods, require multiple

UniTrak kits. The following table lists what is

included for Vertical and Horizontal kits

(See Figure 1):

Document No. 546-00449 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.

For sensors mounted at a 45-degree angle, using the linkage-forming tool, bend the linkage at a 45-degree angle on the mark so the linkage is parallel to the sash (Figure 12). 9. Using the linkage-forming tool, cut or score location that will be broken off (Figure 14). Bend the linkage back and forth until it breaks.

Bends will reduce overall length by 1/2 inch to 1-1/2 inches. A 45-degree angle will clear most obstacles. Estimate the mounting position of the linkage (approximately 1 inch from the top edge of the sash) (Figure 16). FUM0345R1 1. Figure 18. Linkage Clearance Measurement for Dual UniTrak sensors.

Plug the sensor connector into the connector on the end of the UniTrak strip. 2. 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. FUM0378R1 Red Black 546-00175 1.
