APPLICATION INFORMATION
The JABSCO 18590 series dc macerator pump unit is the
ideal solution for emptying marine holding tanks when not in a
discharge restricted area. The JABSCO macerator is selfpriming to a five foot lift when impeller is wet, four foot when
dry, and may be mounted in any convenient point in the waste
discharge system. The macerator section grinds waste down
to a particle size of 1/8" maximum so it can easily by pumped
through a 1" ID discharge hose. The pump section is selfpriming, 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.)
The macerator has an approximate flow rate of 12 GPM and
will empty 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 marine and recreational
vehicle waste systems. IT WILL NOT HANDLE HARD SOLID
OBJECTS, SANITARY NAPKINS OR RAGS.
Motors meet USCG Electrical standards (Title 33, Chapter I,
Part 183; Subpart I) for IGNITION PROTECTION on gasoline
powered vessels and ISO 8846.
OPERATING INSTRUCTIONS
The macerator should be controlled by a momentary switch
positioned close enough to the pump so it can be heard while
operating. When the tank is empty there will be a change in
pump noise (louder, higher frequency) at which time the
macerator should immediately be switched off.
The macerator pump unit has been designed to handle waste,
toilet tissue, and facial tissue. It will also handle solids such as
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 longer than 30 seconds or impeller and
pump damage may result. Make sure the battery is fully
charged. The dc motor is suitable only for intermittent duty and
should not be run for more than 15 minutes continuously.
After long periods of nonuse, the flexible impeller may stick to
the pump body preventing the macerator pump from turning
freely. If this occurs, the impeller can be broken free by
removing the plastic cap on the shaft at the rear end of the
motor, inserting a screwdriver in the slot and rotating the shaft
clockwise a quarter turn or more. When impeller is broken free,
reinstall the plastic cap on the motor shaft.

INSTALLATION INSTRUCTIONS
WIRING
Locating the Pump: The JABSCO macerator is self-priming to a
five foot lift when impeller is wet, four foot when dry, and may be
mounted in any convenient point in the waste discharge system.
It may be mounted in any position or angle without affecting
performance. Use the rubber grommets provided to absorb
vibration. Do not overtighten mounting screws. For optimal
performance, mount the pump as close to tank as possible.
NOTICE: Correct motor polarity (orange to positive, black to
negative) is important. Reverse polarity can damage motor
and void warranty.
Plumbing Connections: Use 1-1/2" ID noncollapsible (radiator
type) suction hose. Slip the hose over the inlet hose barb and
secure it with two stainless steel hose clamps.
Use stranded copper wire of the correct size (determined from
the electrical specifications chart) to connect the macerator to
the power source. An appropriate size fuse or equivalent
circuit breaker (determined from electrical specifications
chart) must be installed in the positive power lead within
seven inches of the power source. Connect the positive lead
to a heavy-duty momentary switch (see required switch amperage rating in electrical specifications chart) positioned close
enough to the macerator so the operator can hear the macerator
while it is running. Extend the positive lead from the switch to
the macerator and connect it to the orange (positive) motor lead.
Connect the black (negative) motor lead to the negative side of
the battery or grounded buss bar.
The macerator may also be screwed directly into a 1-1/2" N.P.T.
tank flange or female pipe fitting. If attaching the inlet port to a
pipe fitting it often requires removing the hose barb portion of the
port with a hack-saw. If this is necessary, cut across the hose
barb portion of the port about 1/8 inch away from the end of the
pipe threads. Wrap port threads with a couple wraps of Teflon*
tape and screw the pump assembly into the pipe fitting. Tighten
hand tight, do not overtighten.
NOTICE: An air leak anywhere in the suction side of the
plumbing system can cause extended dry running which may
result in damage to the impeller and pump.
All suction connections must be airtight and free of sharp bends
or restrictions. If a waste deck fitting is installed (for dockside
pump-out), it too must be airtight to ensure proper priming.
Make certain there are no air leaks around the deck plate cap or
hose tail. Use minimum 1" ID hose for discharge and connect to
thru-hull fitting located approximately 4-6 inches above waterline.
NOTICE: The discharge thru-hull may be positioned below the
waterline only if the discharge hose has a vented loop fitting
installed at least 8" above the waterline at all angles of heel or
trim. Consult with a qualified marine plumber.
* Teflon is a trademark of E.I. DuPont de Nemours and Company.
Full voltage at the motor is required to properly operate the
macerator. It must be wired in a circuit independent of all other
accessories.

Remove the four acorn nuts (Key 1) and fiber washers (Key 2) from
the pump studs (Key 3). Slide the macerator housing (Key 4) off the
studs. Insert a thin bladed 9/32" (7 mm) ignition wrench behind the
chopper plate (Key 5) and onto the flat of the motor shaft to prevent it
from turning. Unscrew (counter-clockwise) the locknut on the end of
the motor shaft and remove the stainless steel chopper blade. †
Remove the pump wearplate (Key 6) and two paper gaskets (Key 7).
Now slide the pump body (Key 10) with impeller (Key 8), small
wearplate (Key 9), two studs and shaft seal as an assembly off the
motor shaft and remaining two mounting studs. Remove the starlock
retaining washer on the seal and push the seal out of the seal bore.
If reconditioning pump with a service kit (Part No. 18598-1000), it is
not necessary to remove the seal because the new seal is
pre-installed in the new body. It is also generally not necessary to
remove the slinger or brass studs screwed into the motor end bell.

If installing a new seal, push it into the seal bore of the body with
the lip pointing toward the impeller bore. Press the starlock washer
into the seal bore with the concave side up to secure the seal in the
bore. Install the two shorter studs in the two holes with threaded
inserts in the new pump body and tighten finger tight. If required,
screw the two longer studs into the tapped holes in the motor end
bell. Slide the new pump body with the shaft seal installed onto the
motor shaft and two long mounting studs in the motor. Slide the
small wearplate over the motor shaft and position it in the bottom of
the impeller bore. Slide the new impeller onto the motor shaft and,
with a counter-clockwise motion, push it into the pump impeller
bore. Position one new gasket on the studs and against the pump
body assuring the cut-out aligns with the inlet groove in the body.
Position the large wearplate and second gasket on the studs and
against the body again aligning the hole in the wearplate and
gasket cut-out with the pump inlet. Position the chopper on the
end of the motor shaft with drive tab aligned with flat of shaft and
pointing toward the motor. Hold the shaft with the ignition wrench
and secure the chopper to the shaft with the locknut. Position the
macerator housing on the four studs ensuring the cut-out in the
inner wall aligns with pump body inlet port and hole in the
wearplate. Position a new fiber washer on each of the studs and
secure the macerator housing in place with the four acorn nuts.
* These parts are supplied in 18598-1000 Service Kit.
† On pumps manufactured prior to April of 1998, position a screwdriver between
the prongs of the bronze chopper and unscrew it (counter-clockwise) and
remove it with its lock washer from the motor shaft.
