INTRODUCTION
G
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 insure 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 movement
during shipment (Fig. 1).
2. Mounting the pump-the tank
has two slots provided to
mount the unit. The slots are
located on the ends of the tank
(Fig. 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.

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 connections. All wiring
must comply with local codes.
2. L ine vo ltage : C o n ne ct
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
o t her devi ce t hat r uns
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 (Figs.
2 & 3).
4. If fused plug is used on 230V units, a 1.0 amp fuse is recommended.
1. Run flexible tubing or pipe from evaporator drain into one of the three pump
inlets. Be sure inlet piping is sloped downward to allow gravity flow (Fig. 4).
Extend the inlet piping into the tank from 1 to 3 inches to ensure that it will not
interfere with proper float operation. Be sure that the inlet piping is cut at an
angle where it enters the tank.
Fig. 4
2. The outlet piping should be
flexible tubing secured
with a hose clamp (not
provided) or pipe (3/8 inch
I.D. maximum to prevent
excessive flow back to
unit). From condensate
unit, extend discharge
piping straight up as high
as necessary. Do not
extend this line above the
head/GPH of the particular
model being installed.
