WASTE EVACUATION The Jabsco 18590 series DC macerator pump unit is the ideal solution for emptying marine holding tanks when not in a discharge restricted area. It is recommended that holding tanks be flushed with several gallons of water after each pump out. This will reduce the possibility of a continued build up of sediment in the tank which could cause a potential blockage. FISH BOX AND LIVEWELL TANK EVACUATION The Jabsco Macerator Pump is the ideal pump for the emptying of Fish box and livewell receptacles. Very often the livewell tank will be above the waterline of the boat, when this is the case gravity can be used to empty the livewell tank. If not installed in this format then it is beneficial to use the Jabsco macerator pump for evacuation due to its selfpriming capabilities and also it's grinding properties. Fish boxes are typically mounted into the floor of the vessel and are very often below the waterline or only partially above the waterline. Again the Jabsco Macerator pump has the characteristics that lend themselves to this application. The bait residue particles of ice, fish scales and anything else that could potentially be found in the FishBox will be easily passed buy the Jabsco Macerator Pump, and the self priming capabilities are perfect for fish box installations common to many of today's sports fishing boats. GENERAL INSTALLATION SUGGESTIONS The pump can be mounted in any orientation without loss of performance. It is however recommended that if the pump is mounted vertically then the pump head be mounted below the motor Use the rubber grommets provided to absorb vibration The Macerator pump can be screwed directly into a 11/2 Inch NPT tank flange or female pipe fitting. If attaching the inlet port to a pipe fitting it may require removal of the hose barbed port, this can be done using a hacksaw. Wrap port threads with a couple of wraps of Teflon tape and screw the pump assembly into the pipe fitting. Tighten hand tight, do not over tighten. Please Note An air leak anywhere in the suction side of the plumbing system can cause extended dry running. All suction connections must be air tight and free of sharp bends or restrictions. If a deck fitting is installed for dockside pumpout and connected to the suction hose of the macerator by means of a tee fitting, it too must be air tight to ensure proper priming. Use minimum 1 Inch ID hose for discharge and connect to thruhull fitting located approximately 46 inches above waterline. NOTICE The discharge thruhull may be positioned below the waterline only if the discharge hose has a vented loop fitting installed at least 8 Inch above the waterline at all angles of heel or trim. Consult with a qualified marine plumber. INSTALLATION FOR WASTE APPLICATIONS Although the Jabsco Macerator pump can be installed at any convenient point in the waste discharge system, it is recommended that it be installed as close to the holding tank as possible, this will increase the performance of the pump. It is also recommended that the switch used to control the macerator be mounted close enough to the pump that it can be heard whilst in operation, this will allow the operator to hear a change in pump noise when the unit has finished pumping the tank dry. The pump then should be turned off; this will further increase the life of the pump. INSTALLATION FOR FISH BOX AND LIVEWELL APPLICATIONS As with the waste application the Jabsco Macerator Pump can be installed at any convenient point between the fishbox/livewell receptacle and the discharge port. It is recommended that it be installed as close to the tank as possible, this will increase the performance of the pump. It is also recommended that the switch used to control the macerator be mounted close enough to the pump that it can be heard whilst in operation, this will allow the operator to hear a change in pump noise when the unit has finished pumping the tank dry. The pump then should be turned off; this will further increase the life of the pump.Priming 5ft When Wet, 4ft When Dry.
