Installing KBPF3 Standoffs on KRX3 Board

Remove the two unthreaded sleeves over the long screws shown in Figure 5, then remove the two PC board

mounting screws. Each screw has a split lock washer under it.

Lift the KRX3 pc board with the two pony boards and filters attached out of the bottom half of the

enclosure. The board fits snugly in the bottom of the enclosure with small bumps along the edges of the board

resting in small holes along the sides of the enclosure. Lift the board straight up and off of the long screws.

Install the 1/2” (13 mm) standoffs at locations E1 and E3 on the KRX3 pc board (see Figure 5). Use the

hardware exactly as shown in Figure 6. The lock washer between the standoff and the pc board is very important

to establish the correct height above the board.
