 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.
 Wear Personal Protective Equipment as exposed bottom has
sharp edges.
 Check 3-phase pumps for correct rotation prior to installing
pump(s) in basin. To change rotation, reverse any two of the
three power leads to the pump (not the ground). Code the
wires for reconnection after installation.
 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 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 position the pump float directly under the inlet from
drain tile or in the direct path of any incoming water.
 Keep pump upright.
 At no time should the pump be stored within an incomplete
wet pit. The pump should not be placed into the pit until it
can be fully operational.
 Do not allow the pump to freeze.

General Information

Before installation, read these 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.
The LSG/LSGX-Series pumps are to be used for
handling septic tank effluent, sewage, and drain
(storm) water.
Provide pump serial number in all correspondence.
Pumps are CSA certified to CSA and UL® standards.
Pumps must be serviced at a qualified repair facility
approved by Liberty Pumps. No repair work should
be carried out during the warranty period without
prior factory approval. Any unauthorized field
repairs void warranty. Contact Liberty Pumps at
1-800-543-2550 to locate the closest authorized
service center.

Operating Constraints

It is extremely important to verify that the pump
has been sized correctly for the intended
installation. The operating point of the pump must
lie within the acceptable range as outlined by the
applicable Liberty Pumps performance chart.
Operating the pump outside of the recommended
range can invalidate the CSA Certification of the
pump and can also cause damage and premature
failure. Operating outside of the recommended
range can cause the pump to exceed its rated
nameplate amp draw, which will void the pump
certification. It can also cause motor overheating,
cavitation, excessive vibration, clogging, and poor
energy efficiency.
