This instruction sheet provides you with the information required to safely own and
operate your Little Giant pump. Retain these instructions for future reference.
The Little Giant pump you have purchased is of the highest quality workmanship
and material, and has been engineered to give you long and reliable service.
Little Giant pumps are carefully tested, inspected, and packaged to ensure safe
delivery and operation. Please examine your pump carefully to ensure that no
damage occurred during shipment. If damage has occurred, please contact the
place of purchase. They will assist you in replacement or repair, if required.
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO
INSTALL, OPERATE, OR SERVICE YOUR LITTLE GIANT PUMP. KNOW
THE PUMP’S APPLICATION, LIMITATIONS, AND POTENTIAL HAZARDS.
PROTECT YOURSELF AND OTHERS BY OBSERVING ALL SAFETY
INFORMATION. FAILURE TO COMPLY WITH THESE INSTRUCTIONS
COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
SAFETY GUIDELINES
Ensure that the pump is disconnected from the power source before attempting
to service or remove any component.
This pump is not submersible.
Do not handle a pump or pump motor with wet hands or when standing on a wet
or damp surface, or in water.
This pump is supplied with a grounding conductor and/or grounding-type
attachment plug. To reduce the risk of electric shock, ensure that it is connected to
a properly-grounded, grounding-type receptacle.
In any installation where property damage and/or personal injury might result
from an inoperative or leaking pump due to power outages, discharge line
blockage, or any other reason, use a backup system and/or alarm.
Support the pump and its piping during assembly and after installation. Failure
to do so may cause damage to the pump and/or piping.
ELECTRICAL CONNECTIONS
WARNING
This pump must be installed by qualified personnel, following all local electrical
and safety codes, as well as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
Check the pump label for proper voltage required. Do not connect the pump to
any voltage other than that shown.
If your pump is equipped with a 3-prong electrical plug, the third prong grounds
the pump to prevent possible electrical shock hazard. Do not remove the third
prong from the plug. A separate branch circuit is recommended. Do not use an
extension cord when connecting the pump to its power source.
Refer to Table 1 to determine proper voltage. The pumps are pre-configured at
the factory for 115V operation. If 230V operation is required, refer to the label on
the motor for directions on wiring the pump. BE SURE OF PROPER ROTATION.
IMPROPER ROTATION WILL SEVERELY DAMAGE THE PUMP AND VOID THE
WARRANTY.

LEAF BASKET (OPTIONAL)
Little Giant offers an optional leaf basket for use with the OPWG pumps. The
leaf basket is important for providing filtration to the water in the pond and
keeping large debris from going into the pump. The leaf basket is a necessity for
installations where the pump is located above the water source (Figure 3). The
leaf basket is ready for assembly with any of the OPWG series pumps.
INSTALLATION
WARNING
PLEASE READ ALL INSTRUCTIONS BEFORE OPERATING THE OUT-OF-POND
WATER GARDEN PUMP. The Out-Of-Pond Water Garden Pump is not self-priming;
therefore, if the water source is below the pump, a foot valve must be installed and
the pump should be primed prior to startup. Do not restrict the intake of the pump.
Do not pump water with temperatures above 95°F. Pipe used for connecting to the
intake side of the pump should not be of smaller inside diameter than that of the
intake thread designation. THIS PUMP IS NOT SUBMERSIBLE.
NOTE: IT IS IMPORTANT TO LOCATE THE PUMP AS CLOSE AS POSSIBLE TO
THE WATER SOURCE. THIS WILL KEEP THE INTAKE PIPING AT A MINIMUM
LENGTH. USING LONGER SECTIONS OF PIPE AND ADDITIONAL ELBOWS
WILL ADD ADDITIONAL FRICTION LOSSES AND COULD AFFECT THE
PRIMING CAPABILITY AND PERFORMANCE OF THE PUMP.
1. Determine a suitable, permanent location near the water source (pond,
skimmer, filter, etc.) to mount the pump. There are 3 installation options
available for the Out-Of-Pond Water Garden Pump (Figures 2-4).
2. Mount the motor base on a hard, level foundation for all mounting
installations. DO NOT install pump below ground level or in a low-lying
area where flooding could occur. Make sure that the mounting surface has
adequate drainage so that water will not collect around the pump and motor
housing. If possible, when installing the pump, place a protective barrier
over the pump to protect the motor from heavy rainfall, which could damage
the motor and possibly cause electric shock. This barrier should also allow
clearance around pump motor for air circulation.
3. Determine what type of water feature will be used with the pump and
determine its location in reference to the pump. Perform a preliminary
layout of the piping and adapters to determine the proper length of the
pipe sections. Minimize the number of elbows used in the intake and
discharge lines. This will reduce the friction losses and maximize the pump
performance. The intake line coming from the water source should be kept
at a minimum length. Once the layout is determined for the water garden
pond, begin making the permanent connections for the fittings.
4. Use only plastic PVC-type fittings on both the pump intake and discharge
(Table 1). All piping should be 2” PVC or flexible type piping. All threaded
connections should be sealed with Teflon tape and the slip-fit piping
connections should be sealed with PVC cement. Use compatible cement
when connecting PVC piping to PVC adapters or PVC adapters to flexible
piping. All piping should be supported and arranged for ease of alignment
to the intake and discharge ports on the pump (or with the optional leaf
basket). Forcing alignment of the piping to the intake and discharge ports
on the pump volute can cause damage to the volute/leaf basket.
5. The Out-Of-Pond Water Garden Pumps are not self-priming. DO NOT RUN
THE PUMP DRY. A flooded intake is recommended for optimum performance
because it eliminates the risk of running the pump dry or losing prime. THE
LEAF BASKET AND ALL HARD PIPING DOWN TO THE FOOT/CHECK
VALVE MUST BE FILLED WITH WATER BEFORE RUNNING THE PUMP.
6. For in-line use, install the pump so that the pump head (volute) is flooded
when the pump is started. That is, the inlet of the pump must be below the
level of the surface of the liquid being pumped (Figure 1).
When installing the pump above water level, use a foot valve or check
valve on the piping leading to the intake of the pump for pumping from the
water source (pond, skimmer, filter, etc.) The foot/check valve will maintain
the water in the intake line when the pump is not in operation. Figures 2-4
outline some typical installations for the Out-of-Pond Water Garden Pumps.
(See Table 1 for pump intake and discharge sizes.)
7. For all installations, an adjustable ball/gate valve should be used above the
discharge of the pump. The ball/gate valve helps control the water flow for
the water feature being used. When the pump is being serviced, be sure to
close off the ball/gate valve to prevent back-flowing of the water from the
waterfall/water feature.
8. When installing the pump below water level, an additional ball/gate valve
should be installed in the line ahead of the intake or leaf basket so that water
flow from the water source can be shut-off for pump maintenance and/or
cleaning the leaf basket screen. DO NOT USE THIS VALVE TO RESTRICT
THE PUMP INTAKE.
