GINTRODUCTION
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 1" of water
collects in the tank, and automatically switches off when the tank drains to approximately
1/2".
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.
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 THE 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.
P. O. Box 12010
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.
2. Mounting the pump: the tank has two slots provided to mount the unit (Fig. 1). The
slots are located on the end of the tank cover. 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.
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 the 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 (Fig. 2 & 3)-the safety overflow switch should be connected to a Class II
low voltage circuit. Typical hook-up of 'NC' circuits would be:
N.O. When water rises, circuit opens to turn off heating or cooling
equipment.
N.C. When water rises, circuit closes to activate a bell or alarm.
4. If fused type plug is used on 230v units, a 2.0 amp fuse is recommended.
