Installation

To install:

1. Insert the IR Window assembly into the punched hole.

2. Align and rmly 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.
