EC-1-DV & EC-1K-DV Series
OWNER'S MANUAL

This pump is designed to automatically remove condensate water
that drips from wall mount ductless air conditioners up to 34,000
BTU/hr. The EC-1-DV pump is only suitable for intermittent use in
applications with a maximum 50% pump duty cycle and maxi-
mum 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 pump is controlled by a float switch mechanism, which auto-
matically starts and stops the pump. These models also include a
high water level switch, which opens a thermostat circuit or breaks power to the machine when the pump
reservoir is full, stopping production of condensate. Alternatively, this switch can be reconfigured to close a
circuit and operate a relay to sound an alarm, power a warning light, or signal a building management sys-
tem (alarm, light, and BMS are purchased separately).
This product is covered by a Limited Warranty for a period of 2 years from the date of original purchase by
the consumer. For complete warranty information, refer to www.LittleGiant.com
