ROOFTOP AIR CONDITIONER WITH MANUAL CONTROL: Manual controls provide simple operation with physical controls and slim design. The manual controller has 8 selectable positions. Works with both ducted and non-ducted air conditioning systems. Air distribution also has 2 slotted registers to maximize airflow and the registers can be closed to divert more air to the ducts in a ducted system. COOL & ENERGY EFFICIENT: The air conditioner has two fans, each with their own motor, to help move cool air faster inside your RV, making it 25% more efficient than single-fan units. SAFE & RELIABLE: Start capacitor offers an extra boost to help jump-start the AC when a campsite or generator doesn't provide enough power. Short-cycle protection ensures your RV reaches its temperature set-point. DURABLE: UV-resistant cover protects internal components from water and debris while the thermal insulation regulates temperature and prevents motors from overheating. The EPP foam housing is water and chemical resistant. INSTALLATION & WARRANTY: Bolt-on installation. Replaces or adds an additional AC system. Mounting hardware/frame for air distribution box included. The instruction manual included provides detailed information for the full setup.
