INTRODUCTION
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 trouble-free service.
The 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. 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 move-
ment during shipment (Figure 1).

2. Mounting the pump: the
tank has two slots pro-
vided 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 condi-
tioner unit or nearby wall.
Pump must be level and
the inlet must be below
the coil drain. Conduit
fittings are not compati-
ble with the plastic pump
housing.
3. The pump should not be installed in a manner that will subject
it to splashing or spraying.
4. This pump is not intended for use inside air plenums.
ELECTRICAL CONNECTIONS
1. Shut off electrical power at fuse box before making any connec-
tions. 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 recom-
mended.
