Supplemental Installation 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
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

1. For all systems, refer to the primary instructions supplied with
this ejector system or basin for excavating the pit, plumbing
connections, and backfilling.
2. 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. Consult Liberty Pumps at
1-800-543-2550 or a local distributor for more information
on ARC Series Access Risers.
Installing the Pump in the XL-Series Basin or XL Basin
and Cover Assembly Kit
1. 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.
2. Size the length of the discharge piping to reach from the
discharge of the pump to be within the discharge pipe socket
with integral lip seal on the underside of the Pro-Series cover.
Liberty Pumps sewage pumps will use threaded-one-end
(TOE) nipples of 23.75" length for Pro370XL-Series Basins, or
17.50" long for Pro380XL-Series Basins. Install the pipe into
the threaded discharge of the pump.

Lower the pump into the basin, fitting the pump legs into the
torque stops.
Insert power cord for the pump—and the piggyback switch
cord, if so equipped—through the underside of the
inspection cover hole and position cover over pipe nipple
while aligning the bolt holes. Sealant (such as silicone) can be
applied on both sides of the rubber gasket surface to ensure
proper sealing. Use sixteen 1/4-20 UNC bolts and washers to
secure cover to the basin. Tighten bolts to 40 inch-pounds.
Do not overtighten bolts. The soft, integral gasket will
conform to the top of the tank. The bolts may be re-torqued
up to 60 inch-pounds to seal any leaks that may occur during
a 10' stack test.
Liberty Pumps recommends the use of manual type pumps
and the appropriate Liberty Pumps QuickTree Switch Kit for
mounting of pump control and alarm floats. Contact
customer service for ordering information. Install the
QuickTree Kit per instructions included. Liberty Pumps
automatic type pumps with piggyback float switches may also
be used. Lay the power cable and switch cable in the grooves
in the inspection cover recess as shown in the primary
instructions included with this system. Attach the inspection
cover to the main cover using supplied bolts and washers.
Sealant (such as silicone) can be applied on both sides of the
rubber gasket surface to ensure proper sealing. Tighten the
bolts furthest away from the power cord grooves first,
torquing to 40 inch-pounds. Do not overtighten bolts. The
soft, integral gasket will conform to the top of the cover and
power cords. The bolts may be re-torqued up to 60
inch-pounds to seal any leaks that may occur during a 10'
stack test.
