            The ‘Hold n’ Treat System’ is designed to integrate   MODEL NUMBERS:
            both a Type I and Type III MSD (Marine Sanita-     21SR1512    Hold n Treat System with electro scan , 12 volt
            tion Device) to provide the user with a system that   21SR1524    Hold n Treat System with electro scan , 24 volt
            will be legal in all areas.   The Hold n' Treat Sys-  21R151201   Hold n Treat System without EST, 12 volt
            tem combines  Electro Scan (USCG Type I MSD)       21RS152401 Hold n Treat System without electro scan , 24 volt
            and a holding tank into one convenient system.
            All waste is stored in a 15 gallon holding tank with
            Electro Scan mode  determining how the waste
            is processed. This system eliminates the need for
            pump-out stations in most areas.

            OVERVIEW
            When Hold n’ Treat Electro Scan mode is set to
            AUTOMATIC the level of waste in the holding
            tank is monitored . Once the waste level is above
            low level the Electro Scan Control Unit activates a
            macerator pump which moves waste (approximate-
            ly 1 gallon) from the holding tank to the Electro
            Scan. This cycle is repeated continuously for five
            cycles. After the fifth cycle, the system enters a
            cool down cycle. It will remain in the cool down
            cycle for approximately fifteen minutes. After cool
            down, the process will resume until the waste in
            the tank drops below low level.
            When system mode is set to NO DISCHARGE ,           Operation in EPA designated "No Discharge
            processing is inactive and waste is collected in the   Zones" affects the MSD installation on every
