IMPORTANT: Three cord channels are provided. For systems
without the alarm option, only two channels are used and the
third must be "plugged" with an attached rubber plug seal. See
Figure 13 [right]. If the alarm cord is present, all three channels will
be used. All rubber cover gaskets are permanently attached and
do not require replacement.

When servicing the QuickTree, place the switch cord into the
trough or channel and then slip the stainless steel rod through the
clamp. Tighten the screw with a Phillips screwdriver, being careful
not to overtighten. Flats have been stamped on the rod to
designate float position, and the screw should be tightened onto
the flat. Tether length is the amount of cord between the clamp
and float.

Instructions
Pro370XL/Pro380XL-Series 10' Stack Test Basins
XL-Series sewage ejector basins are designed to withstand the 10'
stack test required by some municipalities. Proper installation of
the specified cover flange is essential to ensure that the test is
met. Strict adherence to these instructions is required. Under no
circumstances should the cover be installed in a manner
3"
inconsistent with these instructions.
Types of Systems
XL-Series basins are available as fully assembled systems
complete with pump and discharge piping, as basin and cover
assembly kits with no pump or plumbing, and as basins only.
Follow the instructions below, as applicable, to correspond to the
specific type of system.
Basin Installation
For all systems, refer to the primary instructions supplied with this
ejector system or basin for excavating the pit, plumbing
connections, and backfilling.
If the top of the basin is below grade, an Access Riser (model
ARC18) is required. The maximum burial depth is 18" with respect
to the top of the basin. 370-Series and top discharge 380-Series
systems require an Access Riser for outdoor use. Consult Liberty
Pumps at 1-800-543-2550 or a local distributor for more
information on ARC Series Access Risers.

Basin and Cover Assembly Kit

Liberty Pumps XL-Series basins, purchased separately, will
require the appropriate 16-bolt Pro-Series cover assembly to
make an effectively sealed ejector system. Contact Liberty
Pumps customer service for the proper cover for the
application.
