1. Close to a plain water inlet supply line with a minimum pressure of 12-psig. NOTE: Circulating air, required to cool the refrigeration system’s condenser coil, is drawn in through grille on front and exhausted out through sides and back of Unit. Restricting air circulation through the Unit will decrease its cooling efficiency. 2. When installing Unit, do not allow obstruction to block grille on front which will block off air intake to inside of Unit. If installation dictates only one side or
