This instruction sheet provides you with the information required to safely own and
operate your Little Giant pump. Retain these instructions for future reference.
The Little Giant pump you have purchased is of the highest quality workmanship
and material, and has been engineered to give you long and reliable service.
Little Giant pumps are carefully tested, inspected, and packaged to ensure safe
delivery and operation. Please examine your pump carefully to ensure that no
damage occurred during shipment. If damage has occurred, please contact the
place of purchase. They will assist you in replacement or repair, if required.
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO
INSTALL, OPERATE, OR SERVICE YOUR LITTLE GIANT PUMP . KNOW
THE PUMP'S APPLICATION, LIMITATIONS, AND POTENTIAL HAZARDS.
PROTECT YOURSELF AND OTHERS BY OBSERVING ALL SAFETY
INFORMATION. FAILURE TO COMPLY WITH THESE INSTRUCTIONS
COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
DESCRIPTION
This is an automatic condensate removal pump for water dripping off an air
conditioner evaporative coil. It is controlled by a float/switch mechanism that
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".
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 tab from the motor cover
air slots. This tab prevents switch movement during shipment (Fig. 1).
2. Using the two slots located on the ends of the tank (Fig. 5), mount the unit
either on the side of the air conditioner or on a nearby wall. Ensure that the
pump is level and the inlet is below the coil drain. NOTE: Conduit fittings
are not compatible with the plastic pump housing.
3. Ensure that the pump is installed where it will not be splashed or sprayed.
CAUTION: This pump is not intended for use inside air plenums.

ELECTRICAL CONNECTIONS
1. Shut off electrical power at fuse box before making any connections. Ensure
all wiring complies with local codes.
2. 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. Connect the safety overflow switch to a Class II low voltage circuit. To
control a thermostatic circuit, wire the COM and NO connections from the
safety switch 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. For
typical hook-up of NC circuits, see figures 2 and 3.
4. If a fused plug is used on 230V units, a 1.0 amp fuse is recommended.
1. Run flexible tubing or pipe from the evaporator drain into one of the three
pump inlets, ensuring that the piping is sloped downward to allow gravity
flow (Fig. 4). Extend the piping into the tank from 1 to 3 inches to ensure
that it will not interfere with proper float operation. Cut the piping at an angle
where it enters the tank.
