Along with this the secondary disconnect block assemblies ( Figure 16 , above) for the AKD8 version of the
EntelliGuard Retrofill ACB can be purchased and installed. Here’s how to install:
1. Unpack the secondary disconnect block from the box. The kit comes in just one box. Each kit of
secondary disconnect has 4 fixing nuts, plain washers, and spring washers. These can be arranged on a
work station for preparing to install the secondary disconnect blocks.
2. Check that the bullets, on top of the secondary disconnects, are not damaged and that they are freely
sliding in and out of their individual cylindrical cells, block-by-block. The bullets are spring-loaded and
retracts to their initial positions if they are released from their pressed conditions. It is recommended that
all 21 bullets be tested. Normally, just a visual check is enough for checking non-functioning bullets.
