The Little Giant EC-1U-DV (553527) is a slim undermount mini-split condensate removal pump system designed for wall-mounted ductless air conditioning units. Featuring 110–240V dual voltage operation at 50/60 Hz, it delivers a maximum flow rate of 2.5 GPH at 1 ft of head and up to a 33 ft shut-off head. Its compact undermount enclosure installs directly beneath wall-mounted units for automatic condensate removal when gravity-feed drainage is not available.
We have inspected this item and we do not have the capability to install the unit to fully test it. There are some cosmetic scuffs and scratches throughout the unit. It appears to have gotten wet during storage.
