9.Study the assembly in the pit for a moment and then adjust it so that nothing interferes with the primary pump or its switch. Mark the joints with a permanent marker so that you can realign everything after you pull it out of the pit for gluing (see Figure 3).
NOTE: Take your time with this - it takes care but isn’t very difficult. Be sure you leave enough room for the BBU pump’s vertical switch. Mark everything that might move!
10.After you have marked everything, remove the assembly from the pit.
11.Cut off the vertical discharge pipe at the cut point
you marked in Step 8. BE SURE YOU ARE CUTTING ON THE RIGHT MARK!
12.Recheck the alignment and glue up all the joints on the primary pump assembly.
NOTE: You may need to support the assembly, which won’t balance very well, in order to preserve the alignment while gluing it. Check this before you start gluing. Another pair of hands may help here!
13.After the glue has set, slide the hose coupling and its clamps down over the assembled discharge pipe. If the pipe is
14.Hook the switch clamp over the switch bracket and slide the assembly down over the hose coupling and discharge pipe. Clamp the switch so that the water level when the switch shuts off is above the BBU pump’s intake.
15.Replace the assembly in the pit, slide the hose coupling up over the air gap so that it joins the pipes, and tighten the clamps enough to keep it there.

16.Check fit, alignment, etc. If everything looks good, make sure that the BBU vertical switch is at the right height and free of obstructions, then tighten the hose clamps on the coupling.
17.Adjust the rod stop location on the BBU float rod to give the desired switch travel. If necessary, nip off the bottom of the float rod to provide clearance.
BBU WIRING AND SETUP
See Figures 4, 5, and 6 for battery installation and connection information.
Battery
Inputs
5768 0108
Figure 4: The battery input is inside the battery case. Support the case when opening it. The support must be at least 4” thick.
Figure 5: Install the battery in the case. Have someone support the case while you do this. Once the battery is in the case, connect the leads from the charger/controller: +(Red) to +(Red), and –(Black) to –(Black).
