G INTRODUCTION
This instruction sheet will provide you with information required to
safely own and operate Little Giant PES Series pump. The pump
you have purchased is a submersible epoxy encapsulated pump,
with outer case constructed of durable thermoplastic. The case is
filled with a special heat transfer epoxy.
The instruction sheet primarily covers the standard models of each
pump series. The form is applicable to other models in the series
not listed by catalog number in the replacement parts list section
of the instruction sheet. If the catalog number of your pump is not
listed in the replacement parts list section, then caution should be
exercised when ordering replacement parts. Always give the
catalog number of your pump when ordering replacement parts.
The Little Giant unit you have purchased is of the highest quality
workmanship and material. It has been engineered to give you
long and trouble-free service. The Little Giant pumps are care-
fully packaged, inspected and tested to insure safe operation
and delivery. When you receive your pump, examine it carefully
to determine that there are no broken or damaged parts that may
have occurred during shipment. If damage has occurred, make
notation and notify the firm that you purchased the pump from.
They will assist you in replacement or repair, if required.
READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING
TO INSTALL, OPERATE OR SERVICE THE LITTLE GIANT
PUMP. KNOW THE PUMP APPLICATION, LIMITATIONS, AND
POTENTIAL HAZARDS. PROTECT YOURSELF AND OTHERS
BY OBSERVING ALL SAFETY INFORMATION. FAILURE
TO COMPLY WITH INSTRUCTIONS COULD RESULT IN
PERSONAL INJURY AND/OR PROPERTY DAMAGE! RETAIN
INSTRUCTIONS FOR FUTURE REFERENCE.
SAFETY GUIDELINES
1. Make certain that the unit is disconnected from the power
source before attempting to service or remove any compo-
nent.
2. Do not use to pump flammable or explosive fluids such as
gasoline, fuel oil, kerosene, etc. Do not use in explosive atmo-
spheres. Pump should only be used with clean water. Do not
use to pump heated liquids.
3. Do not handle pump with wet hands or when standing on a
wet or damp surface or in water.
4. This pump is supplied with a grounding conductor and/or
grounding-type attachment plug. To reduce the risk of electric
shock, be certain that it is connected to a properly grounded
grounding-type receptacle.
5. 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,
a backup system(s) and/or alarm should be used.
6. Support pump and piping when assembling and when
installed. Failure to do so may cause piping to break, pump to
fall, motor failures, etc.

ELECTRICAL CONNECTIONS
1. Check the pump label for proper voltage required. Do not connect
to voltage other than that shown.
2. These pumps are supplied with a 3-prong electrical plug, the
third prong is to ground the pump to prevent possible electri-
cal shock hazard. DO NOT REMOVE the third prong from the
plug. A separate branch circuit is recommended. Do not use an
extension cord. Do not cut plug from the cord. If the plug is cut
or the cord is shortened, then this action will void the warranty.
3. The National Electric Code requires that a ground fault circuit
interrupter (GFCI) be used in the branch circuit supplying
fountain pumps and other pond equipment. See your electrical
supplies dealer for this device.
4. To reduce the risk of electric shock, use only on portable self-
contained fountains no larger than five feet in any direction.
CONSULT INSTRUCTION SHEET ILLUSTRATIONS FOR PROPER
ASSEMBLY AND DISASSEMBLY OF YOUR LITTLE GIANT PUMP.
OPERATION
1. The PES model pumps must be operated in clean fresh water
completely submerged. Do not let the pump run dry.
2. The pumps can be placed in any position. There are suction
cup feet provided with the pump. To install the suction cups,
wet the ends and slide them into the slots on the bottom of the
pump housing.
3. The weight of the pumps must be supported adequately. DO
NOT support the pumps by the discharge connection alone.
4. Discharge adaptors are provided with the pump. Find your
pump model on the chart below for available discharge sizes.
5. The flow rate on the PES Series pump can be adjusted using
a valve on the discharge side of the pump or if flexible tubing
is used, a clamp can be used on the tubing.
6. If the unit is going to be idle for a period of time, follow the
cleaning instructions outlined in the next section. Do not let
the unit freeze in the wintertime. This may cause cracking or
distortion that may destroy the unit.
SERVICE INSTRUCTIONS
MAKE CERTAIN THAT THE UNIT IS DISCONNECTED FROM
THE POWER SOURCE BEFORE ATTEMPTING TO SERVICE OR
REMOVE ANY COMPONENT!
1. This unit is permanently lubricated. Oiling is not required.
2. To disassemble the pump for cleaning, remove the front screen
by gently squeezing on the sides and pulling from the main
body in the oval area. Remove the impeller. NOTE: The impel-
ler shaft is held in place by two rubber end cups (one at each
end). Make sure these end cups are used when reassembling
the pump after cleaning. Use a small brush or stream of water
to clean any corrosion or debris from the impeller, shaft, and
the impeller cavity. Reassemble the parts in reverse order.
3. If pump is tripping circuit breakers or not operating properly
after cleaning, return it to Little Giant or its authorized service
center. DO NOT attempt repairs yourself.
4. Be certain power cord is in good condition and contains no
nicks or cuts.
5. Do not modify, cut, saw, sand or grind any part of the pump.
Doing so can cause harmful emissions.
