For pressure sewer applications
, 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 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.
Submersible Pump—do not run dry.
Do not introduce any consumer item that is not toilet paper
into a non-grinder (dewatering/effluent or sewage) pump/
pump system. This includes, but is not limited to the
following: feminine products, 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.
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 allow pump to freeze.
Model Specifications
For a complete listing of models and their specifications, refer to
www.LibertyPumps.com/LEP/About/Engineering-Specs. The
pump nameplate provides a record of specific pump information.
Introduction
Pumps and control panels are supplied with their own separate
Installation/Operation manuals. Ensure receipt of these manuals,
and that they are read and understood prior to installing and
using this system. Familiarity with the pump and control panel 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 or control panel operation. For
questions, call Liberty Engineered Products customer service at
1-800-543-2550.
Identification
Information about the LEPS can be found on a metal tag located
on the basin cover. This identifies the LEPS model number and
electrical specifications per pump, as well as system information
and date. Pump tags are located on the pump(s). Duplicate pump
tags are packaged with the system. These should be mounted on
the basin cover or the control panel for accessibility and
immediate 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 control panel.
Notify the carrier immediately if there is any damage.
Basin Installation
This is a brief reference to the recommended methods and
procedures for installing Liberty Pumps underground basins to
ensure that damage or premature failure of the basin does not
occur.
This section is
not
intended to serve as a basic instructional guide.
The installation of Liberty Pumps basins is a specialized skill and is
assumed that the individuals who install our products and refer to
this section will have basic understanding of such procedures as
excavating, backfilling, pipefitting, and electrical work. No amount
of written instruction by a manufacturer or regulatory agency will
convert an inexperienced, under-supervised laborer into a skilled,
experienced mechanic. The ability to recognize and correctly
respond to abnormal conditions during a basin installation
requires field experience as well as mechanical aptitude. Figure 1
is provided for reference.
In addition to proper system engineering and competent
manufacturing, the use of basin installers who have both practical
experience and integrity to assist that the basin be installed
properly, constitutes the greatest protection from catastrophic
basin failure and liability exposure.
Basin Handling
General Handling
Although the exterior surfaces of the fiberglass basins are
designed to withstand normal handling, they can be damaged
during transportation and installation. Basins must not be
dropped, dragged, or handled with sharp objects, and with the
exception of the minimal movement involved in a visual
inspection, must not be rolled.
Unloading, Lifting, and Lowering
RISK OF SERIOUS INJURY OR DEATH
Under no circumstances are the use of chains or cables
around the basin shell permitted.
The proper way to move a basin is by lifting it, using chains or
cables with the optional lifting lugs (not more than a 30° angle), or
by using a non-marring sling around the basin. Before any
attempt is made to move a basin, verify that all equipment and
accessories have sufficient capacity and reach to lift and lower the
basin without dragging and/or dropping. Maneuver the basin with
guide ropes attached to the sides.
