submerged electrical connections can energize the water. Do
not enter the water if the water level is higher than the PPE
protection or if the PPE is not watertight.
◼Do not lift or carry a pump or a float assembly by its power
cord. This will damage the power cord, and could expose the
electrically live wires inside the power cord.
◼The electrical power supply shall be located within the length
limitations of the pump power cord, and for below grade
installations, it shall be at least 4 ft (1.22 m) above floor level.
◼Do not use this product in applications where human contact
with the pumped fluid is common (such as swimming pools,
fountains, marine areas, etc.).
◼Protect the power and control cords from the environment.
Unprotected power and control (switch) cords can allow
water to wick through ends into pump or switch housings,
causing surroundings to become energized.
◼Do not use an extension cord to power the product.
Extension cords can overload both the product and extension
cord supply wires. Overloaded wires will get very hot and can
catch on fire.
◼This product requires a separate, properly fused and
grounded branch circuit, sized for the voltage and amperage
requirements of the pump, as noted on the nameplate.
Overloaded branch circuit wires will get very hot and can

NOTICE
Do not use pumps with fluid over 140°F (60°C). Operating
the pump in fluid above this temperature can overheat the
pump, resulting in pump failure. Maximum continuous duty
fluid temperature is 104°F (40°C).
Do not use pump system with mud, sand, cement,
hydrocarbons, grease, or chemicals. Pump and system
components can be damaged from these items causing
product malfunction or failure. Additionally, flooding can
occur if these items jam the impeller or piping.
Do not run dry.
The Uniform Plumbing Code®states that sewage systems
shall have an audio and visual alarm that signals a
malfunction of the system, to reduce the potential for
property damage.
Do not exert heavy pressure or run heavy equipment on the
backfill material as this could cause the tank to collapse.
Do not overtighten bolts.
Do not position the pump float directly under the inlet from
drain tile or in the direct path of any incoming water.
1100-Series are not suitable for outdoor applications.
Introduction
Before installation, read the following instructions carefully. Each
pump is individually factory tested to ensure proper
performance. Closely following these instructions will eliminate
potential operating problems, assuring years of trouble-free
service.
ProVore®grinder systems easily handle solids and sewage
waste found in typical residential applications. Their unique
cutter system grinds difficult wastes and then pumps it through
a 1-1/2” or 2” discharge line. The ProVore 680-Series system is
supplied with a 2” discharge outlet. Do not increase this pipe
size above 2” as adequate flow rates may not be achieved for
proper operation. Discharge sizes may be reduced to 1-1/2” or
1-1/4”. Consult Liberty Pumps for proper pipe and system sizing.
Pro-Series systems come with an integral control system with
alarm and QuickTree® float system. Pump and alarm floats are
pre-set on the QuickTree system at proper operating levels. The
QuickTree system is located under a separate access cover for
ease of maintenance and service. Floats for both pump
activation and alarm are mounted on a stainless steel tree (rod),
separate from the pump. There is no need to disconnect
plumbing or remove the pump to inspect service or replace
floats. QuickTree floats are preset at the factory for optimum
operating levels and should not be adjusted.
Pro-Series systems also feature a clear disposable construction
cover designed to protect the system during rough-in and
masonry work. The protective cover should remain in place until
finish plumbing; however, it can be removed and reinstalled if
required. The cover is snapped into the threaded ports of the
discharge and vent. To remove the clear cover, simply pull
upward, disengaging it from the discharge and vent holes.
1100-Series systems feature a heavy-duty basin with 4” inlet
hub pre-assembled to basin. Floats are tethered to a removable
standpipe/access cover assembly. The cover is equipped with a
2” or 3” discharge and 2” or 3” vent flange. Installation is limited
to indoor only.
Was current system sized by a professional? Minimum fluid
flows are required in sewage applications. Consult Liberty Pumps
for proper pump sizing prior to installation.

Cover Descriptions In-Ground Basin
Installation
ProVore and Pro-Series basins can be installed in both indoor and
outdoor applications. The 1100-Series basins are not suitable for
outdoor applications and can only be installed indoors.
A. Excavation: Excavate the hole as small as possible, with a
minimum recommended 8” diametrical clearance around the tank.
Never place the basin directly in contact with rocks or other sharp
objects. Place only fine, 1/8” to 3/4” pea gravel or 1/8” to 1/2”
washed, crushed stone as bedding between the basin and the hole
walls. Do not use sand or native soil as backfill. Properly compact
underneath the basin to provide a solid, level base that can
support the weight of the filled basin. It is recommended that the
top lip of the basin be level with the finished floor.
B. Initial Backfill: Only fine, 1/8” to 3/4” pea gravel or 1/8” to
1/2” washed, crushed stone should be used around the bottom of
the basin to hold it in place. Do not use sand or native soil as
backfill. Make the inlet connection as required for particular basin.
C. Inlet Connection: Pro-Series basins have a 4” inlet molded to the side of the tank. This inlet is sized to accept a 4” no-hub
type coupling. 1100-Series basins use a hub with a 4” seal for inlet connection.
Connect the gravity drainage line from the fixtures to this hub.
D. Final Backfill: Large rocks, clods, and foreign objects should
be kept out of the backfill material. Only fine, 1/4” to 3/4” pea gravel, or
1/8” to 1/2” washed, crushed stone is recommended. Do not use sand or
native soil as backfill. Mound the backfill slightly and allow for natural
settling. Provide access to the basin cover for maintenance and service.
Do not exert heavy pressure or run heavy equipment on the backfill
material as this could cause the tank to collapse.
Installation and Connections
1100-Series are not suitable for outdoor applications.
The ProVore680 and 1102/PRG systems are supplied with
dual 2” discharge outlets.
Do not increase the pipe size above 2” as adequate
flow rates may not be achieved for proper
operation. Discharge sizes may be reduced to 1-1/2” or 1-1/4”. Contact Liberty Pumps with
questions regarding proper pipe sizes and flow rates.
E. Discharge: Using an adapter, connect the discharge pipe to the threaded 2” or 3” port provided
on the cover.
Install the remaining discharge line. A union should be
installed just above the cover to facilitate pump removal.
A check valve is required after the union to prevent the
backflow of liquid after each pumping cycle. A gate or ball
valve should follow the check valve to allow periodic
cleaning of the check valve or removal of the pump. The
remainder of the discharge line should be as short as
possible with a minimum number of turns, to minimize
friction head loss. Contact Liberty Pumps or other qualified
person if there are questions regarding proper pipe size and
flow rates.

Figure 5 shows a typical installation. Variations may apply to
actual installation.
Figure 5. Typical Installation (Pro680-Series shown)
F. Vent: A 2” or 3” vent
connection is provided
on top of the 1100-Series
unit. The P680-Series
vent is in the tank. The
vent must be piped to
the existing building vent,
or extended outside on
its own standpipe.
The vent size should be in accordance with applicable codes,
but not less than the discharge size.
QuickTree and Pro680-Series Access Cover
Liberty Pumps Pro680-Series systems feature QuickTree
technology. The QuickTree float system uses a stainless steel
mounting rod (tree) and specially designed cord clamping
brackets to affix the pump floats in the system. All floats are
preset at the factory at optimum operating levels and should
not be adjusted. Field adjusting floats may cause improper
activation or turn-off of the pump and optional alarm.
QuickTree removal and float inspection: The QuickTree system
is located under the separate access cover to help ease
inspection, service, and replacement of a float. To inspect the
floats, simply unbolt the access cover and lift out the QuickTree
assembly from its holder. There is no need to disconnect
plumbing or remove the pump. Pro680-Series systems feature a
manual pump (with no switch attached directly to the pump).
Operation of the pump is accomplished by the QuickTree system.
Re-inserting the QuickTree: After service or inspection of the
floats, re-insert the QuickTree into its holder. It is important that
cords from the pump motors and float switch, and optional alarm
float are properly sealed in the specially designed rubber sealing
channels under the access cover. Proper sealing is required to
keep sewer gas from leaking from the system. Place the cords
securely in the rubber channels as shown in Figure 6 [left], being
careful to remove excessive cord “slack” from inside the system.
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 6 [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.

P680-Series System Controller
P680-Series systems are connected to a controller that monitors
the operation of the pumps. The controller will automatically
alternate between the two pumps each cycle to maintain equal
wear. It will also monitor for high water conditions and alarms if
necessary. The controller has visual indicators that show the
operation of the sump as well as operator controls to test
functionality. The controller will also identify a non-functioning
component. For complete operation, refer to the user manual for
the controller.
Liberty Pumps offers both an indoor (Figure 9) and outdoor
(Figure 10) version of the controller.
Note: The cord ends must be removed in order to wire the
outdoor controller.

Supplemental Installation Instructions
PRO680XL-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
For all systems, refer to the primary instructions supplied with this
ejector system or basin for excavating the pit, plumbing
connections, and backfilling.
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 utilize a 17.50”
long toe nipple for 680XL-Series Basins. Install the pipe into
the threaded discharge of the pump.
3. Lower the pump into the basin, fitting the pump legs into
the torque stops.
4. 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.
5. 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
