Waste Water Tank Dumping:

To dump the exterior black waste water tank:
1. Remove macerator hose from storage location.
2. Attach the rubber plug, (stored in the storage compartment behind the large access door), to the end of the
macerator sewage hose valve assembly.
3. Securely place the rubber plug and assembly in the local waste receptacle.
4. Pull the black water gate valve handle, (to open) to dump the tank contents.
5. Turn macerator pump on using the macerator on button, located on the drivers seat pedestal to
dump waste tank.
To dump the grey waste water tank:
1. Follow the same procedure using the grey water gate valve handle located behind the front small
access door.
2. Be sure to dump the grey waste water tank last, so as to help flush out any solid waste in the sewage
hose from the black waste water tank.
3. Once the tanks are empty, close the gate valves, remove the fitting, return the assembly to its support
structure and ensure that the sewage hose valve is closed and store the sewage hose.
4. If desired, flush both waste tanks after dumping.
NOTICE: It is recommended to always dump the black water tank first, then the grey water tank. This will keep the
hose and pump cleaner and will prevent any solids from fouling the macerator pump.
NOTICE: The macerator has a manual crank handle to help release blockages (See picture B-P43). Push in on the
handle and rotate to engage the slot in the pump shaft, then rotate handle counter-clockwise.
CAUTION: The Macerator pump can be damaged if allowed to operate dry for any length of time. Please ensure
that the pump is turned off as soon as the tanks are empty.
