Installation
To install:
1. Insert the IR Window assembly into the punched hole.
2. Align and firmly hold the IR Window in place.
3. Apply a slight amount of torque to each of the four jam-nut screws to break
them loose from the install position.
4. Incrementally tighten each jam-nut screw in a cross-pattern to the torque
recommended in Table 4. This torque makes sure that the frame gasket is
compressed for an optimum seal. See Figure 6.
Note
If a calibrated torque driver is not available, be careful that you do not over
tighten and break the jam-nut screws.
