SAMSUNG should recall this product immediately from market like it did with it's tablet as this product has faulty outer body design. squirrels, rats & birds can easily enter the unit due to big gaps provided in body of outer unit. nI have installed 5 units at my place & ended up paying Rs 10,000/- per unit as wires, PCB board, condenser parts are eaten away. Every 3 months the fan gets jammed by figs brought by birds.nPLEASE DON'T BUY.
