Safety Guidelines
Safety Precautions
Accidental contact with electrically live parts, items, fluid, or
water can cause serious injury or death.
Always disconnect pump(s) from power source(s) before
handling or making any adjustments to either the pump(s),
the pump system, or the control panel.
All installation and maintenance of pumps, controls,
protection devices, and general wiring shall be done by
qualified personnel.
All electrical and safety practices shall be in accordance with
the National Electrical Code®, the Occupational Safety and
Health Administration, or applicable local codes and
ordinances.
Do not remove cord and strain relief, and do not connect
conduit to pump.
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
Do not handle or unplug the pump with wet hands, when
standing on damp surface, or in water unless wearing
Personal Protective Equipment.
Always wear dielectric rubber boots and other applicable
Personal Protective Equipment (PPE) when water is on the
floor and an energized pump system must be serviced, as
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.
Unprotectedpowerandcontrol(switch) cords can allow water
to wick through ends into pump or switch housings, causing
surroundings to become energized.
Single-phase 208/230V pumps shall only be operated without
the float switch by using the circuit breaker or panel
disconnect.
Some products may have internal capacitors that could cause
shock. Avoid contact with plug ends after removing from
energy source.

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
catch on fire. When used, electrical outlets shall be simplex of
the appropriate rating.
Do not use this product with or near flammable or explosive
fluids such as gasoline, fuel oil, kerosene, etc. If rotating
elements inside pump strike any foreign object, sparks may
occur. Sparks could ignite flammable liquids.
These pumps are not to be installed in locations classified as
hazardous in accordance with the National Electric Code®,
ANSI/NFPA 70.
Sewage and effluent systems produce and may contain
flammable and explosive gases. Prevent introduction of
foreign objects into basin as sparks could ignite these gases.
Exercise caution using tools and do not use electronic devices
or have live, exposed electrical circuits in or around basins,
open covers and vents.
Energizing the control panel or breaker for the first time is
potentially dangerous. Licensed electrical personnel should
be present when the panel or breaker is energized for the first
time. If faults caused by damage or poor installation practices
have not been detected, serious damage, injury or death can
result when power is applied.
Do not modify the pump/pump system in any way.
Modifications may affect seals, change the electrical loading
of the pump, or damage the pump and its components.
All pump/pump system installations shall be in compliance
with all applicable Federal, State, and Local codes and
ordinances.
Do not allow children to play with the pump system.
Do not allow any person who is unqualified to have contact
with this pump system. Any person who is unaware of the
dangers of this pump system, or has not read this manual, can
easily be injured by the pump system.
In 208/230V installations, one side of the line going to the
pump is always “hot”, whether the float switch is on or off. To
avoid hazards, install a double pole disconnect near the pump
installation.
Vent basin in accordance with local code. Proper venting of
sewer and effluent gases alleviates poisonous gas buildup
and reduces the risk of explosion and fire from these
flammable gases.
Wear adequate Personal Protective Equipment when working
on pumps or piping that have been exposed to wastewater.
Sump and sewage pumps often handle materials that can
transmit illness or disease upon contact with skin and other
tissues.
Do not remove any tags or labels from the pump or its cord.
Keep clear of suction and discharge openings. To prevent
injury, never insert fingers into pump while it is connected to
a power source.
Do not use this product with flammable, explosive, or
corrosive fluids. Do not use in a flammable and/or explosive
atmosphere as serious injury or death could result.
This product contains chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. www.p65warnings.ca.gov.
A grinder pump contains metal parts that rotate at high
speeds. Be careful around pump base while power is
connected. Make sure that the pump is either in the tank or
clear from people and wires when in operation.
This pump has been evaluated for use with water only,
however use with human waste and toilet paper is permitted.
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.
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 introduce any consumer item that is not toilet paper
into a non-grinder (dewatering, effluent, sewage) pump/
pump system. This includes, but is not limited to the
following:feminineproducts, wipes, towels, towelettes, dental
floss, swabs, pads, etc. Items such as these put the pump
under undo strain and can result in pump/pump system
failure. Additionally, it creates conditions for discharge line
blockage.
Submersible Pump—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.
1100-Series systems are not suitable for outdoor applications.
Unless specifically noted, covers are not traffic rated.
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 (including ProVore 1100-Series) 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.
RISK OF FIRE
RISK OF SERIOUS INJURY OR DEATH

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
preset 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 (non-grinder types) 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.
Was the current system sized by a professional? Minimum fluid
flows are required in sewage applications. Consult Liberty Pumps
for proper pump sizing prior to installation.

Outdoor Basin Preparation
1100-Series systems are not suitable for outdoor applications.
Unless specifically noted, covers are not traffic rated.
For outdoor installation of a P680 system, an ARC18 Access Riser
and X8-D extension must be used. The ARC18 and X8-D
combination allows for outdoor installation up to 26 inches below
grade. Refer to Figure 1.
Figure 1. P680 Typical Outdoor Installation
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.
Initial Backfill
Use only fine, 1/8” to 3/4” pea gravel or 1/8” to 1/2” washed,
crushed stone 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.
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. Connect
the gravity drainage line from the fixtures to this hub.
Final Backfill
Large rocks, clods, and foreign objects must 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.
Note: Do not exert heavy pressure or run heavy equipment on the
backfill material as this could cause the tank to collapse.
Installation
All installation and maintenance of pumps, controls,
protection devices, and general wiring shall be done by
qualified personnel.
All electrical and safety practices shall be in accordance with
the National Electrical Code®, the Occupational Safety and
Health Administration, or applicable local codes and
ordinances.
