4.15 Booster Bar Installation

4.15.1 Installing a 24" booster bar
If possible, in an A-B system it is recommended to turn off the side in which the booster bar is being installed.
1. There are a total of six nuts which hold the main internal return and the input connector together (only two
should be removed).
2. Remove the two bottom nuts that are vertically in line, and nearest the back of the system. Keep the nuts.
3. Remove the two bolts that hold the main internal return bar to the glastics that are mounted on the side panel.
These two bolts are the ones closest to the back panel and closest to the input connector.
4. Cover the booster bar with electrashield if desired.
5. Have the booster bar oriented with the two mounting holes at the top and the side with the holes towards the
front of the BDFB.
6. Insert the bottom end of the booster bar at a steep downward angle into the fourth opening at the top of the
enclosure.
7. Once the booster bar is inside the enclosure, rotate it into a vertical position.
8. Lift it straight up, and then hang it on the top two mounting PEMs (the ones from which the two nuts were
removed).
9. Re-install the two nuts (that were removed in step 2) on the top of the booster bar.
10. Install three more nuts along the length of the bar wherever the PEMs protrude (see note below on correct
bolts size).
11. Install the bolts through the booster bar and the main return bar into the glastics which mount to the side.
Refer to Table C on page 21 for the correct torque values.
NOTE:
Use the correct bolts.
New bolts are provided in the upgrade kit for this purpose; the original bolts are not the
correct length for sufficient engagement and if the bolts are too long they will bottom
out in the glastic before the parts are properly clamped. There are different lengths of
bolts to be used if the 24" bar is being mounted to the main bar directly or if it is being
mounted over a 48" bar.
