            Do not operate therefrigerator on 12  Volt
            when the vehicle is parked.You  will run
            out of battery in a rather short time.
            If possible the installation of a 12Volt ope-
            rated  refrigator should be completedwith
            a relay mounted either in the car or in the
            vehicle (see diagram). This realy will au-
            tomaticallycut out the refrigeratorwhen
            the car motor is stopped.
