Black / Gray Tank Drains w/Macerator
System
Your motor home is equipped with a macerator pump system used to discharge waste from
the gray and black waste tank. The system has a 1-1/2-inch diameter exible hose located
beneath the utility center panel or in a separate hose storage compartment. Not all models
are equipped with external storage compartment. The system when powered on can
discharge waste (uphill if necessary) up to a distance of 150 feet.
Pull the 1-1/2 inch exible hose with the attached dump connector
from under the utility center or out of the external compartment. The
dump connector includes two connections: a small removable cap for
attaching a 3/4 inch garden hose, or a larger 3-inch removable cap,
which allows it to be attached to the sewer outlet at the dump station.
(The ex hose can extend to 21 feet).
1. Attach the dump connector to the 3-inch sewer outlet at the dump
station, or to a 3/4 inch garden hose and run the hose to a dumping
location.
2. Empty the tanks one at a time. Black tank should be emptied rst
followed by the gray tank so waste water from the gray tank will
help rinse solids or debris from the dump connector and ex hose.
3. Pull the black tank T-handle to open the drain. (To close the tank drain, push the
T-handle in). Typically, the handle is located in the utility center or in a separate
compartment next to the hose storage box.
4. Turn the Macerator power switch ON at the utility
center panel and the macerator pump will begin
sending waste through the dump hose.
5. When the tank is empty, turn the macerator power
switch OFF. Close the black tank drain T-handle.
Before operating the macerator pump, make sure the external dump hose is
properly attached at the motor home and at the dump station. The hose is
under pressure and therefore waste is discharged under pressure.
Water can accumulate in the exible hose and dump connector of the macerator
system. When winterizing the RV, antifreeze must be added to the macerator
system. Refer to the Winterizing section.
