Condensate piping can be directed through the inside wallto an approved drain or straight outside.INSTALL INDOOR UNITPlan the installation carefully before you begin.1. Select indoor unit location.a. A location that can bear the weight of the unit.b. Do not install indoor units near a direct source of heatsuch as direct sunlight or a heating appliance.c. Do not install units too close to humid conditions.2.
