This pump should be used in accordance with EPA Sanitation Regulations. APPLICATION The Jabsco 18590-series DC macerator pump unit is the ideal solution for emptying holding tanks on recreational vehicles and avoiding dump stations.The macerator sec- tion grinds waste down to a particle size of 1/8" maxi- mum so it can easily be pumped through a 1" ID dis- charge hose. The pump section is self-priming, permitting the unit to be mounted above the tank in a convenient location. (For optimal efficiency, locate pump as close to holding tank as possible.) Recommendation: Purchase a commercial 1" garden hose and cut off a 1 to 2 foot length of the outlet end. Attach this short hose to the macerator 1" outlet. Now attach the swivel female connector to the short hose male connector. You can now easily remove and store the 1" service hose. Empties most recirculating toilets in less than 2 minutes; empties a typical 30 gallon holding tank in less than 3 minutes. The 18590-series waste pump will macerate and pump all waste and tissue normally found in recreational vehicle waste systems. IT WILL NOT HANDLE HARD SOLID OBJECTS, SANITARY NAPKINS OR RAGS. Model: 18590-0010 OPERATING INSTRUCTIONS The Jabsco macerator pump unit has been designed to handle waste, toilet tissue, and facial tissue. It will also handle solids such as filter tip cigarettes, cigars and chunks of soft fruits or vegetables less than 1" size. It will not pump solid objects like peach pits, rags, or sanitary napkins. The holding tank and pump should be flushed with several gallons of water after each pumpout. Do NOT run pump dry. Make sure the battery is fully charged. The DC motor is suitable only for intermittent duty; do not run for more than 15 minutes continuously. After long periods of nonuse, the macerator pump may not turn freely. Pour a cup of water down pump discharge line to help free the impeller. The motor shaft has a screw driver slot machined at the rear of the motor. This may be used to free a stuck impeller after months of non use.
