EC-1-DV
The EC-1-DV model is designed to accommodate multiple electrical requirements within one pump.
The DV suffix indicates that the pump is capable of operating from a wider range of supply voltages
to maintain consistent performance. Similar to our EC-1 model, this model incudes improved noise
reduction, reliable solid-state switching technology, and easy to install mounting brackets to create a
pump that benefits contractors, installers, and end-users.

Summary of Contents for Little Giant EC-1-DV
- Page 1 EC-1-DV ‘Suction Lift’ Condensate Pump The EC-1-DV model is designed to accommodate multiple electrical requirements within one pump. The DV suffix indicates that the pump is capable of operating from a wider range of supply voltages to maintain consistent performance. Similar to our EC-1 model, this model incudes improved noise reduction, reliable solid-state switching technology, and easy to install mounting brackets to create a pump that benefits contractors, installers, and end-users.
- Page 2 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.
- Page 3 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! SAFETY GUIDELINES SHUT OFF ELECTRICAL POWER AT FUSE- OR BREAKER- BOX BEFORE ATTEMPTING TO SERVICE, DISCONNECT CONNECTOR, OR REMOVE ANY COMPONENT! Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc.
- Page 4 INSTALLATION This section guides the user to install the EC-1 using the most common configuration of condensate water removal from wall-mount, ductless mini-split air conditioners. In this configuration, the reservoir is installed inside and behind the air handler, with the reservoir inlet connected directly to the air handler condensate drain hose.
- Page 5 Be certain that the bottom of the reservoir is within (+/-) 8 degrees of being level with the optimum performance being when the reservoir is level. Use care to ensure the reservoir will remain level throughout its operating life. If the reservoir is not mounted properly, the float mechanism may not function properly and may cause the unit to overflow.
- Page 6 Reservoir-to-Pump Tubing: For convenience, the reservoir assembly is equipped with three outlet ports, one vertical and two horizontal. Choose an outlet port on the reservoir assembly, remove port cap, and connect the 5/32" ID x 3 ft (4mm ID x 1m) tubing onto selected port.
- Page 7 MODEL (voltage) EC-1 or EC-1K (115 V) EC-1 or EC-1K (230 V) EC-1-DV or EC-1K-DV (110 - 240 V) FUSE 0.50 A 0.20 A 0.50 A OVERFLOW PROTECTION SWITCH CONNECTIONS The unit is equipped with an overflow protection switch with a maximum rated switching current (resistive load) of 3 amps at 250 VAC or 3 amps at 30 VDC.
- Page 8 If the overflow protection switch is wired to the normally open configuration described above, the alarm or bell (purchased separately) should sound. The alarm or bell should continue to sound until the pump lowers the water level in the reservoir to a middle level associated with alarm-off position. When the pump has removed enough of the water to allow the overflow protection switch to deactivate, the air conditioner should come on or the alarm or bell should stop sounding, depending on the configuration used.
