Evaporator Placement - Heatcraft Refrigeration Products II Installation & Operating Instructions Manual

(refer to build plans for actual room layout and equipment location)
The ADT/LET units are draw through units. For best operation, they should be located away from entry
doors and at least 18" from the wall with the fans blowing into the room. Make sure the units are flush
mounted to the ceiling to insure proper drainage for defrost water.
