• March AB-1F, AB-2F and AB-2F UL Condensate Pumps are designed to mount BELOW the evaporator pan. It is preferable to mount the pump as close to drip pan drain as possible to minimize actual lift and to clear components usually found on floor of most A.C. units. The pump is designed to mount on side of A.C. unit, or on wall near unit by using the two ears on each end of the plastic sump.
• The Condensate Pump Inlet is a 1" diameter hole with a rubber grommet in the top metal plate. Attach a 1" O.D. rubber or plastic tube to the evaporator drip pan drain connection and lead it down into the pump inlet hole.
• The Outlet fitting is a 90 degree angle tube fitting to which you attach 1/4" I.D. plastic tubing.
• Maximum vertical discharge head (lift) is 17 feet with 1 quart drink per cycle.
• The AB-2F UL models are UL listed and have a fan cooled motor, separate high and low voltage terminal boards, a safety float, and include 20 feet of 1/4 inch tubing.
• The AB-2F Models are the same as the AB-2F UL but do not have a fan or the separate high / low voltage terminal board.
• The AB-1F Models are similar to the AB-2F but do not have a safety float.
