SAFETY GUIDELINES
1. Make certain that the unit is disconnected from the power source
before attempting to service or remove any component.
2. Do not use to pump flammable or explosive fluids such as
gasoline, fuel oil, kerosene, etc. Do not use in explosive
atmospheres. Pump should only be used with liquids compatible
with pump component materials.
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
bearing failures, etc.

7. If pump is an oil-filled pump, the motor housing is filled with a
dielectric lubricant at the factory for optimum motor heat transfer
and lifetime lubrication of the bearings. Use of any other lubricant
could cause damage and void the warranty. This lubricant is
non-toxic; however, if it escapes the motor housing, it should
be removed from the surface quickly by placing newspapers
or other absorbent material on the water surface to soak it up,
so aquatic life is undisturbed.
ELECTRICAL CONNECTIONS
1. Check the pump label for proper voltage required. Do not connect
to voltage other than that shown.
2. If pump is supplied with a 3-prong electrical plug, the third prong
is to ground 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.
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. If the cord is equipped with stripped lead wires, such as on 230v
models, be sure that the lead wires are connected to a power
source correctly. The (green/yellow) wire is the ground. The
(blue or white) and the (brown or black) are live.

ASSEMBLY AND DISASSEMBLY OF YOUR LITTLE GIANT PUMP .
OPERATION
1. The PES model pumps must be operated in clean fresh water
with the volute intake below the liquid level.
2. The pumps can be placed in any position. There are four suction
cup feet provided with the pump. To install the suction cups, wet
the ends and press them into the four holes on the bottom of the
volute housing.
3. The weight of the pumps must be supported adequately. DO NOT
support the pumps by the discharge
4. There are two discharge adaptors provided with the pump. The
larger discharge adaptor is designed for use with 1/2" ID tubing.
To connect to 3/8" ID tubing, slide the ribbed end of the smaller
adaptor in the 1/2" ID adaptor then connect tubing.
5. The flow rate on the PES Series pump can be adjusted by
sliding the flow control located on the back of the pump. Slide
the control toward the "+" sign to increase flow and toward the
"–" sign to decrease flow. If flow rate needs to be reduced even
further, place 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.
