Available on all new equipment or as an easy-to-install,drop-in replacement aftermarket part from InterLink CommercialRefrigeration Parts. Because they are a drop-in replacement for existingshaded pole and PSC motors, installation is quick and easy. It’s a highimpact, quick payback solution for reducing costs and achieving greeninitiatives without replacing the entire system.EC motors by InterLink are up to 75% energy efficient - that’s a51-59% increase over shaded pole motors and a 30-35% increaseover permanent-split capacitor (PSC) motors. With all of this addedefficiency, you can count on more energy savings and lower operationalcosts while taking a step in the right direction toward conserving ourplanet’s resources.Nomenclature2ADT120AGKModel SeriesCapacityElectrical CodeControl OptionDesign RevisionADT Air defrostLET Electric defrost, 6 FPILLE Electric defrost, 4 FPIHGT Hot gas defrost# x 100 BTUH (R-404A)A 115/1/60 (PSC)B 208-230/1/60 (PSC)C 208-230/3/60 (PSC)M 460/1/60AE 115/1/60 (EC)BE 208-230/1/60 (EC)CE 208-230/3/60 (EC)G intelliGen
