Failure to do so could result in a fatal electric shock. WARNING: Fire and Explosion Hazard DO NOT use this pump to move flammable or explosive liquids.
General Information This pump is designed to automatically remove condensate water that collects from appliances such as air conditioners and dehumidifiers. The pump has a built‑in tank that collects water from the appliance. When collected water reaches sufficient level inside the pump tank, the unit switches on and pumps water to a remote location for removal. When the tank is sufficiently empty, the pump automatically switches off.

Testing Overflow Switch (if connected) Manually overfill tank with water. If overflow safety switch is wired correctly, appliance will shut down, condensate pump will pump out water, and a red LED will illuminate.
Operation LED Indicator Status LED STATUS Green Indicates pump has power and is ready. Amber Indicates pump is running and removing condensate from tank. Red Indicates pump is in alarm mode and that the system is shutoff/disabled (if connected).
Maintenance and Disassembly Always disconnect power before performing maintenance.
