3. Empty the tanks one at a time. Empty the black tank rst
followed by the gray tank so waste water from the gray
tank will help rinse solids or debris from the dump con-
nector and ex hose.

In the event the macerator pump malfunctions, there is a macerator bypass valve. Depend-
ing on your model, this valve may be located in the utility center, in the compartment with
the black/gray tank valves or under the motor home (accessible through the generator com-
partment). This bypass will dump the waste (using gravity ow) from the black/gray tanks
to a 3-inch sewer hose connection.
To operate:
1. Attach a 3-inch sewer hose to the bypass connection , and
to a sewer outlet at a dump station.
2. Empty the tanks one at a time. Black tank should be emp-
tied rst followed by the gray tank so waste water from
the gray tank will help rinse solids or debris from the
dump outlet and hose.
3. Pull the black tank dump valve located.
4. Pull the manual macerator bypass valve to open it and the black tank will empty by
gravity ow.
5. Close the black tank dump valve, and then close the macerator bypass valve.
6. Open the gray tank dump valve, and then open the macerator bypass valve.
7. When nished, make sure both black and gray tank dump valves are closed, shut o
the macerator bypass valve, and disconnect the sewer hose from the motor home and
at the dump station.
8. Clean and store the sewer hose.
9. Replace the dust cap on the macerator bypass.
The black tank ush inlet can be used with the macerator bypass (refer to the Black Tank
Flush section).
