Your Little Giant condensate pump is designed as an automatic 
condensate removal pump for water dripping off an air conditioner 
evaporative coil. The pump is controlled by a float/switch mechanism 
which turns the pump on when approximately 2-1/4" of water 
collects in the tank, and automatically switches off when the tank 
drains to approximately 1-1/4".
The Little Giant unit you have purchased is of the highest quality 
workmanship and material. It has been engineered to give you long 
and reliable service.
Little Giant pumps are carefully packaged, inspected and tested to 
ensure 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. INSTALLATION AND CONNECTIONS 
ARE TO BE MADE BY A QUALIFIED PERSON.

SAFETY GUIDELINES

DO NOT USE TO PUMP FLAMMABLE OR EXPLOSIVE FLUIDS 
SUCH AS GASOLINE, FUEL OIL, KEROSENE, ETC. DO NOT USE 
IN EXPLOSIVE ATMOSPHERES. PUMP SHOULD BE USED WITH 
LIQUIDS COMPATIBLE WITH PUMP COMPONENT MATERIALS.
DO NOT HANDLE PUMP WITH WET HANDS OR WHEN STANDING 
ON A WET OR DAMP SURFACE, OR IN WATER.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.
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.
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.

INSTALLATION

  1. Before installing pump, allow air conditioner to cycle several 

times, collecting condensate in a separate container to help 
flush any residual oils that may remain in the system.

 2.  Carefully unpack the pump. Remove the cardboard packing 

from the motor cover air slots. Carefully slide the packing 
away from the pump. This packing is used to prevent switch 
movement during shipment (Figure 1).

 3.  Mounting the pump: the tank has two slots provided to mount 

the unit. The slots are located on the ends of the tank (Figure 
5). The unit should be mounted either on the side of the air 
conditioner unit or nearby wall. Pump must be level and the 
inlet must be below the coil drain. Conduit fittings are not 
compatible with the plastic pump housing.

 4.  The pump should not be installed in a manner that will subject 

it to splashing or spraying.

 5.  This pump is not intended for use inside air plenums.

ELECTRICAL CONNECTIONS

 1. Shut off electrical power at fuse box before making any 

connections. All wiring must comply with local codes.

 2.  Line voltage: Connect power cord to line voltage specified on 

motor and nameplate. Power cord must be connected to a 
constant source of power (not a fan or other device that runs 
intermittently). If power cord does not have a plug, wiring is as 
follows: green (or green/yellow)—ground. Black (or brown)—
line. White (or blue)—neutral.

 3.  Safety switch: The safety overflow switch should be connected 

to a class II low voltage circuit. To control a thermostatic circuit 
the COM and NO connections from the safety switch are to be 
wired in series with the low voltage thermostat circuit to shut 
down the heating/AC circuit. The COM and NC switch contacts 
may be used to actuate a low voltage alarm circuit (connected 
in series) if the heating/cooling system can not be disrupted. 
The safety switch comes from the factory with leads connected 
to the COM and NO switch terminals. Typical hook-up of “NC” 
circuits would be (Figures 2 & 3).

 4. If fused plug is used on 230V units, a 1.0 amp fuse is 

recommended.
