G INTRODUCTION
This instruction sheet will provide you with information required
to safely own and operate the Little Giant Electronic Condensate
Unit. Your Little Giant EC-400 Series Electronic Condensate Unit
is uniquely designed as an automatic condensate removal system
to remove the water that drips from a split-system air conditioner
evaporative coil when gravity-feed drainage is not possible. The
EC-400 pump is suitable for intermittent use in applications with
a maximum 50% pump duty cycle and maximum 3-minute pump
ON cycle. To maintain a maximum 50% duty cycle, the pump must
have at least twice the flow rate of the condensate produced at
the head required by the application. The EC-400 is suitable for
most split-system A/C units up top 25,000 BTU/hr, but the amount
of condensate produced by an air conditioner is dependent on
the properties of the inside and outside air and the characteristics
of the air conditioner used. Check with the air conditioner manu-
facturer for the amount of condensate that will be produced for a
given application.
The Electronic Condensate Unit consists of two parts—the water
collection reservoir and control unit/pump. The water collector
reservoir is to be positioned near the bottom of the air handler.
The control unit/pump can be affixed internal or external to the air
handler.
Automatic operation is achieved through the use of a float/switch
device inside the water collection reservoir that turns the pump on
when approximately 1/2 inch (14mm) of water collects in the water
collection reservoir, and automatically switches off when the water
collection reservoir drains to approximately 3/8 inch (10mm).
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.
SAFETY GUIDELINES
SHUT OFF ELECTRICAL POWER AT FUSE BOX BEFORE
ATTEMPTING TO SERVICE, DISCONNECT CONNECTOR OR
REMOVE ANY COMPONENT!
1. Do not use to pump flammable or explosive fluids such as
gasoline, fuel oil, kerosene, etc. Do not use in explosive atmo-
spheres.
2. Do not handle pump with wet hands or when standing on a
wet or damp surface or in water.
3. In any installation where property damage and/or personal
injury might result from an inoperative or leaking pump, dis-
charge line blockage, etc., a backup system(s) and/or alarm
should be used.
4. 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.
5. The control unit/pump is not submersible and must be
installed so that water cannot be dripped, splashed or sprayed
onto the control unit/pump.
