 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 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.
 This product contains chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. www.p65warnings.ca.gov.
 Check 3-phase pumps for proper 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 104°F (40°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 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.
 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.

be fully operational.

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.
XLE-Series pumps are to be used for handling
septic tank effluent, sewage, and drain (storm)
water.
Provide pump serial number in all correspondence
and reports.
Pumps are certified by CSA Group to CSA®, UL®,
and FM standards for use in hazardous locations
with division classification of Class 1, Division 1,
Groups C and D; or as zone classified Class 1, Zone
1, and Groups IIA and IIB.
Pumps must be serviced at a qualified hazardous
motor enclosure repair facility approved by Liberty
Pumps. Any unauthorized field repairs void
warranty and hazardous location ratings. Contact
Liberty Pumps at 1-800-543-2550 to locate the
closest authorized repair facility.

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.
