Installation and Operation Instructions Reducing the passive heat load is critical to yield the highest efficiency out of an Outdoor Cooler and maximize service life. It is important to insulate the walls of an enclosure with as much insulation material as permissible without interfering with nearby electronics or system level obstructions. Proper insulation of the enclosure can result in sizing a smaller Outdoor Cooler unit and power supply, which can reduce total system costs. ...
