Mounting and Aligning an IFU

4.3 Mounting an IFU

IFUs are installed in the location specified by each site drawing.

4.3.1 Installing and Adjusting an IFU Sling

Follow each step of this procedure only if an IFU sling is not already secured to an IFU when the

IFU shipping container is opened. Otherwise, use this procedure as a guideline to ensure that the

IFU sling has been properly secured to the IFU.

1. If the sling is not already placed over an IFU, carefully remove the sling from its container.

2. Inspect the sling for any damage or wear that could adversely affect the operation or

performance of the sling, such as rips, tears, cuts, frays, holes, or other similar damage.

3. Place the IFU on a flat surface and slide the sling under the back side of the IFU, away from

the radome.

4. Position the sling on the IFU with its identification label facing outwards (see Figure 4-3).

5. Ensure that the sling is centered around the backside of the IFU. When properly positioned,

the top handle and side handles of the sling should be in the positions shown in Figure 4-3.

The opened end of the sling should be positioned towards the back of the IFU, opposite the

radome.

6. Slide the extended strap through the buckle. Insert the strap under, over, and through the

buckle (see Figure 4-4). Pull the strap tight and knot or bury the slack for additional safety.
