OPERATION
1. The PE-2.5 model pumps must be operated with the volute intake below the liquid level.
2. The pumps can be placed in any position.
3. The weight of the pump must be supported adequately. DO NOT support the pumps
by the discharge connection alone. Pump may be supported by using the two mount-
ing holes in the back of the pump. The holes are designed for #8 self-tapping screws.
Hole depth is .37 DO NOT exceed the hole depth.
4. Do not attempt to restrict the intake side of these pumps. Restricting the intake may
cause damage to the seal and may starve the pump. If you require reduced flow rates,
then place a valve on the discharge side of the pump or if flexible vinyl tubing is used,
a clamp can be used on the tubing to restrict the flow.
5. Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid.
You may damage the seal and the motor may fail if the pump is allowed to run dry.
6. If the unit is going to be idle for a period of time, follow the cleaning instructions out-
lined in the next section. Do not let the unit freeze in the wintertime. This may cause
cracking or distortion that may destroy the unit.
7. The adaptor (item 6) is a press on style with no threads for connecting fountain heads
with 1/2" MNPT to the 3/8" MNPT pump discharge.
8. If fused type plug is used on 230 volt units, a 2.0 amp fuse is recommended.
SERVICE INSTRUCTIONS
MAKE CERTAIN 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. The power cord on these
units cannot be replaced. In case of damage the whole unit must be replaced.
2. First remove the intake screen from the pump. Screen is screwed on and can be re-
moved by turning counterclockwise. Then remove the 3 screws which attach the
volute.
3. Lightly clean any corrosion or debris which may clog the impeller. Use a brush and
penetrating oil and lightly scrape to remove encrusted material.
4. Turn the impeller by hand to make sure it turns freely. Set pump down so the pump and
impeller are not touching anything. Plug the unit into GFCI circuit for 10 seconds to see
if the impeller turns; a) If it is rotating and GFCI did not trip, unplug unit and install parts
in reverse order in which they were removed. b) If it does not rotate, if pump is tripping
circuit breakers, or not operating properly after cleaning, return to Little Giant Pump
Company or its authorized service center. DO NOT attempt repairs yourself.
