Shroud
The shroud on the Duo Therm RV air conditioner is the casing holding the inner parts, engine, thermostat and fans. Fasteners, gaskets, grommets and screws proprietary to the shroud are used to fasten it to the roof of the RV and to make the unit self-contained. A kit/shroud charge indicator is attached to the exterior of the shroud. To protect the RV roof, a shroud and kit foam block is used under the unit and between the roof.
Engine
The engine powers the unit and charges the heating and cooling coils. A capacitor, six pole plugs, protector overload, fasteners and grommets are parts of the engine section. Six different color wires are used to connect the electricity from the RV to the air conditioner. If you are an electrician, you understand the color-coded wires used. Non-electricians should not try to change wiring.
Fan and Blower
The engine attaches to a fan and blower. The engine powers the heating and cooling coils and then the fan pushes the cooled air through to the blower which blows the cooled air into the RV cabin. The fan has four blades and attaches to the fan blower via grommets, proprietary screws, fastening plates and an inlet ring. A bulkhead evaporator and cover evaporator attach to the fan and engine and act as dehumidifiers for the cooled air being pushed into the RV.
