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 EC-1 pump series comprises the following
models: EC-1, EC-1-DV, EC-1K, and EC-1K-DV. The EC-1 and
EC-1K models include a variety of pumps to accommodate
varying electrical requirements (i.e. voltage and frequency) while
the EC-1-DV and EC-1K-DV accommodate multiple electrical
requirements within one pump. The "DV" suffix indicates a pump
model that senses the application's voltage and frequency (within
the rated range), then automatically adjusts internally to maintain
pump performance.
The entire EC-1 Series of pumps (hereafter referred to as "EC-1")
are automatic condensate removal systems designed to remove
the water from a ductless mini-split air conditioner evaporative
coil when gravity-feed drainage is not possible or practical. Even
where gravity drainage is possible, the EC-1 may be a better
choice, minimizing the opportunity for property damage due to
a clogged or air-locked gravity drain line. Additionally using the
EC-1 allows the placement of the indoor air handler anywhere in
the room, not just located on an outside wall, to take advantage
of gravity draining of condensate to the outside.
The EC-1 pump is only 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-1 is suitable for most ductless mini-split A/C units up to

34,000 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 manufacturer for the amount of condensate that
will be produced for a given application. Make certain that you
have determined that the flow rate of the EC-1 is enough to remove
the condensate during the most severe temperature conditions.
See performance curve for typical pump flow rate and maximum
amount of condensate that can be removed for any given discharge
head. Failure to consider this could result in overflowing of water
from the condensate pump reservoir.
The EC-1 consists of two main parts, the water collection reservoir
and control unit/pump. The water collection 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.
The EC-1 operates automatically when condensate water drains
into the reservoir by gravity. The reservoir contains switches
controlled by a float that rises and falls depending upon the
amount of water inside the reservoir. As water enters the reservoir,
a float rises and causes a switch to activate the pump. As the
pump empties the reservoir, the float lowers and causes a switch
to deactivate the pump when the reservoir is almost empty. A
small amount of water always remains in the reservoir after each
pump cycle.
The reservoir also includes a filter screen that should be inspected
periodically and cleaned when necessary. Failure to inspect and
clean the filter screen may result in blockage inside the reservoir
resulting in water overflowing from the reservoir.
The pump also includes an overflow protection switch circuit that
can be connected to stop the air conditioner equipment if the
pump is unable to empty the reservoir. This feature should be
used as it can prevent property damage due to overflowing water
from the air conditioner. The use of this feature is described in
detail below under electrical connections.
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
