Macerator Pump 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 flexible 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 flexible 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 flex hose can extend to 21 feet).
Using the macerator system:
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 first
followed by the gray tank so waste water from the gray tank will
help rinse solids or debris from the dump connector and flex 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.
Make sure
the sewer hose is connected before turning the
macerator on.
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.
Failure to
follow instructions can lead to possible injury or property damage. The
use of this system for anything other than intended will void the warranty.
Water can accumulate in the flexible 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.
