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.
These pumps are not to be installed in locations classified as
hazardous in accordance with the National Electric Code
®
,
ANSI/NFPA 70.
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 enter a pump basin after it has been used. Sewage and
effluent can emit several gases that are poisonous.
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.
Verify a Redundant Check Valve Assembly (curb stop and
check valve) is installed between the pump discharge and
the street main, as close to the public right-of-way as
possible, on all installations to protect from system
pressures
.
Do not dispose of materials such as paint thinner or other
chemicals down drains. Doing so could chemically attack and
damage pump system components and cause product
malfunction or failure.
Do not use these 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 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.
Introduction
Pump, alarm, and plugger box are supplied with their own
separate Installation/Operation/Maintenance manuals. Ensure
receipt of these manuals, and that they are read and understood
prior to installing and using this system. Familiarity with the pump,
alarm, and plugger box is critical.
This manual provides a brief overview of the system, and deals
mainly with inspection and installation of the basin. It does not
cover the specifics of the pump, alarm, and plugger box
operation. For questions, call Liberty Pumps customer service at
800-543-2550.
Identification
Information about the system can be found on a tag located on
the basin cover. This identifies the system model number as well
as the horsepower, voltage, and amp draw for the pump. Pump
tags are located on the pump. Duplicate pump tags are packaged
with the system. These should be mounted on the basin cover or
at the plugger box for accessibility and specific pump information.
Inspection
Inspect the system upon arrival to ensure that there is no shipping
damage. Pay careful attention to the condition of the fiberglass
basin, control floats, pump guide rail brackets, and plugger box.
Notify the carrier immediately if there is any damage.
Read all instructions and become familiar with the system’s
operation prior to proceeding with the installation.
