Electrical Connections; Operation - Little Giant 2-MDQ-SC User Manual

10. Make sure the pump is securely installed before operating it.
11. Read and observe all the important notices on the pump.
12. If an extension cord is necessary, a cord with a proper rating
should be used. A cord rated for less amperes or watts than the
pump rating may overheat. Care should be taken to arrange
the cord so that it will not be tripped over or pulled.
13. 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.
14. 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, BACKUP SYSTEM(S)
AND/OR ALARM SHOULD BE USED.
15. 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.
16. 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

Check the pump label for proper voltage required. Do not connect
to voltage other than that shown.
GROUNDING INSTRUCTIONS: This appliance should be ground-
ed to minimize the possibility of electric shock. This appliance is
equipped with an electric cord having an equipment grounding
conductor and a grounding-type plug. The plug must be plugged
into an outlet that is installed and grounded in accordance with all
appropriate codes and ordinances. This appliance is for use on a
normal 120 volt circuit, and has a grounding plug that looks like
the plug illustrated in Figure 2. This pump should not be used with
a three to two grounding adaptor.

OPERATION

1. The pump is supplied completely preassembled and pretested
from the factory. Make sure the nuts (Figure 3, item 13) are
tight before operating the pump.
2. Use a thread sealer on all pipe connections and hand-tighten
only.
3. The pump is not self-priming. It must be operated with the
volute intake below the liquid level.

4. This pump is not submersible. Operate the pump only in the
in-line mode. DO NOT put the pump in liquid. Pump should be
located in a well ventilated area and away from where accidental
water spillage would cause wetting of the pump.
5. The weight of the pump must be supported adequately. DO
NOT support the pump by the intake and discharge connec-
tions alone.
6. Do not allow the pump to run dry (without liquid). Heat buildup
caused by friction will damage the pump parts when dry.
7. Do not attempt to restrict the intake side of these pumps.
Restricting the intake may cause damage to the pump head.
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.
8. If the pump is to be idle for a period of time, follow the cleaning
instructions outlined in the next section. Do not let the pump
freeze in the wintertime. This may cause cracking or distortion
that may destroy the pump.
AQUARIUM APPLICATIONS
When using this pump for aquarium filter applications, refer to the
instructions and owner's manual supplied by the filter manufacturer.
SERVICE INSTRUCTIONS
MAKE CERTAIN THAT THE PUMP IS DISCONNECTED FROM
THE POWER SOURCE BEFORE ATTEMPTING TO SERVICE
OR REMOVE ANY COMPONENT!
1. The motor's sleeve bearings should be lubricated every six
months with two to three drops of S.A.E. 20 weight non-detergent
oil. The oil holes are located on top at each end of the motor.
2. All wetted parts can be serviced by removing the 4 nuts
(Figure 3, item 13) which hold the volute to the housing. The
pump head components can easily be replaced in the field if
necessary.
3. Lightly clean any corrosion or debris which may clog the
impeller.
4. If pump is tripping circuit breakers or GFCI, or not operating prop-
erly after cleaning, return it to Little Giant or its authorized
service center. DO NOT attempt repairs yourself.
