Little Giant EC-1U-DV Series Owner's Manual

OWNER'S MANUAL
EC-1U-DV Series
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-1U-DV pump is only suitable for intermittent use in applica-
tions with a maximum 50% pump duty cycle and maximum 3-minute
pump ON 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 automati-
cally starts and stops the pump. These models also include a high
water level switch, which opens a thermostat circuit 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, activate a warning light, or signal a building management
system (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.
