Typical Applications Condensate removal units are perfect for use as wastewater drain pumps for icemakers, beverage dispensers, drinking fountains, water coolersm dehumidifiers, central air conditioning units and gas condensing furnaces. The "Lift" or "Head" of the pump is the height the pump is required to "lift" the water up to the drain. The distance the water needs to travel horizontally once the lift is achieved is called "the run". The "run" does not effect the lift or flow rate of the pump unless it exceeds 50 feet. "Runs" of 50' or more decrease pump output by about 10%. Typical Installation A residential central air conditioning unit or gas condensing furnace produces condensate at a rate of up to a gallon per hour. The condensate from the appliance drains into one of the condensate pump removal unit inlet ports. A plastic tubing is installed from the condensate unit discharge port to a drain line, sump, French drain or laundry sink. A check valve on the unit prevents flow reversal. Safety Switch A properly wired auxiliary safety switch is recommended The auxiliary safety switch will shut down the appliance in the event of a pump overflow condition that could lead to property damage. Pump overflow can be caused by a blocked discharge line, power loss to the pump, or pump malfunction. Normally open or normally closed switch can be connected to shutdown the appliance or wired to an alarm to warn of possible tank overflow.
