2.
DO NOT HANDLE UNIT WITH WET HANDS OR WHEN STANDING ON A WET OR DAMP
SURFACE OR IN WATER.
3.
DO NOT PULL THE PUMP OUT OF THE WATER BY THE POWER CORD WHEN THE PUMP IS
OPERATING OR CONNECTED TO POWER SOURCE.
4.
THIS PUMP IS SUPPLIED WITH A GROUNDING CONDUCTOR AND /OR GROUNDING TYPE
ATTACHMENT PLUG. TO REDUCE THE RISK OF ELECTRICAL SHOCK, BE CERTAIN THAT IT
IS CONNECTED TO A PROPERLY GROUNDED GROUNDING TYPE RECEPTACLE.
5.
THE NATIONAL ELECTRIC CODE REQUIRES A GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
BE INSTALLED IN THE BRANCH CIRCUIT SUPPLYING FOUNTAIN EQUIPMENT, POOLS, ETC.
6.
IN ANY INSTALLATIONS 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.
7.
SUPPORT PUMP AND PIPING WHEN ASSEMBLING AND WHEN INSTALLED. FAILURE TO DO
SO MAY CAUSE PIPING TO BREAK, PUMP TO FAIL, MOTOR BEARING FAILURES, ETC.
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 plug is to ground the pump to prevent
possible electrical shock hazard. DO NOT REMOVE the third 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 other two are live.
OPERATION
1.
The 1-EA style pumps must be run submerged. The pump should be placed with the screen as a
base or with cord up. The volute should always be flooded or under water. If the surface is sandy or
muddy a separate hard surface such as a brick should be provided under pump to help prevent
clogging of the screen.
2.
The 1-EA-42 style pumps may be operated submerged or inline. They may be positioned at any
attitude, but preferably with the volute located down or to the side.
3.
The weight of the pumps must be supported adequately. DO NOT support the pumps by the discharge
connection alone. Pumps may be supported by using the two mounting 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 operate dry. 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 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. Do not, in any case, open the sealed
portion of the unit or remove housing screws.
2.
Periodic cleaning of the pump parts will prolong the LIFE and EFFICIENCY of the pump. Refer to
the drawing below for the assembly and disassembly of the pumping head.
3.
First remove the screen from the pump. Then remove the 3 screws as indicated by the arrows. (DO
NOT remove other screws which may be exposed).
4.
Lightly clean any corrosion or debris which may clog the impeller. Use a brush and penetrating oil
and lightly scrape to remove encrusted material.
5.
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.
6.
Be certain power cord is in good condition and contains no nicks or cuts.
