4. Remove the O-Ring around the discharge port.
5. Grip the flat of the shaft where it has been exposed by the
remove top pump assembly to prevent it from rotating.
Unscrew and remove the chopper and its lock washer.

evenly against the shaft seal to press it out of the bore.
WASTE PUMP REASSEMBLY:
1 .Press the lip seal into the seal bore of the pump body
with the open side of the seal facing the impeller bore.
2. Lubricate the impeller bore of the body and the motor
shaft with petroleum jelly then slide the pump body
onto the shaft.
3. Slide the impeller onto the shaft and with a counter-clock-
wise motion push the impeller into the impeller bore.
4. Position a new paper gasket, wearplate and second
paper gasket on the shaft against the pump body.
5. Grip the flat of the shaft on the top end of the motor to
prevent it from turning. Install the chopper lock washer
and the chopper on the bottom shaft.

the open side of the seal facing the impeller bore.
2. Lubricate the impeller bore of the body and the motor
shaft with petroleum jelly.
3. Slide the pump body onto the shaft and secure it to the
motor with two screws. Slide the impeller onto the shaft
and with a clockwise rotary motion press it into the
impeller bore of the body.
4. Push the inlet control valve assembly into the cylinder
above the inlet port.
5. Position the switch spring on the spring locator post.
Insert the dowel pin in the switch and slide the pin in its
channel to position the switch. Connect the red power
leads to the switch.
6. Press the brass wearplate into the impeller bore area
ensuring the locator notch aligns with the locator tab in
the body.
7. Position the cork gasket over the top of the flush pump
housing. Position the flush pump cover on the housing
and secure it with the seven long screws. Hint: When
installing screws, press firmly downward on the screw
and rotate it counterclockwise until you feel the thread
‘click’ into its groove, then screw it in until tight.
8. Position the control knob in its socket and secure it with
one short screw. Install the Electric Flush Pump
Assembly on the toilet base by following instructions for

OPERATION
NOTICE: Do not run pump dry for more than ten sec-
onds. To do so may result in damage to the pump
impeller.
To flush the toilet simply turn the large flush control knob
clockwise to the flush position. In the flush position the
flush Pump provides rinse water to the bowl while the
waste pump simultaneously macerates and discharges
the waste. Hold it in the flush position long enough to
evacuate all waste.
To evacuate liquid from the bowl so it will not slosh while
underway, turn the flush control knob counterclockwise to
the drain position. In the drain position the flush pump will
lower the liquid level to the bottom of the china bowl while
incoming rinse water is reduced to a minimum.
If the toilet bowl is empty, a small amount of water may
be added to the bowl prior to use by turning the flush con-
trol knob to the flush position.
The waste pump is designed to handle waste and toilet
tissue (either household type tissue or Marine/RV water
soluble tissue is acceptable) but it will not handle sanitary
napkins, tampons or hard solid objects.
