NOTE: It is important to note that harmful and toxic materials can accumulate if the holding
tanks are not regularly drained and thoroughly rinsed. It is also important to use holding tank
deodorizing and cleaning agents in the waste water tanks to reduce odors and keep the lines
open and free-flowing.
NOTE: Always remember to clean up the dumpsite before leaving. NEVER empty your holding
tanks directly on the ground, a roadway, river or stream. DO NOT POLLUTE.
1. Remove the sewer drain hose from its storage compartment inside of the systems
compartment.
2. Remove the cap from the vehicle sewage drain, and connect the drain hose to it.
3. Attach the other end of the flexible drain line to the dump station inlet. Make sure both
ends of the flexible drain lines are securely attached.
4. Drain the black tank first, by pulling the termination valve handle toward you. Make sure
to allow sufficient time for the tank to completely drain, and then rinse the tank with
several gallons of water by flushing the stool. Close the valve on the stool and let it fill
before releasing the tank. This creates additional force to flush the tank more
completely.
5. Drain the gray water tank by pulling the termination valve handle toward you.
Draining the gray water tank last, with its soapy water helps to further rinse the drain
and flexible hose.
6. When tanks are emptied, close termination valves by pushing handles back to the
closed position.
7. Remove flexible drain hose and wash it thoroughly with clean water. Remove the other
end from the dump station inlet, and replace it in the storage compartment. Secure the
sewer hose storage cover, and replace the caps on both the motorhome outlet and the
dump station inlet.
The following guidelines will help to ensure trouble free operation:
• Never put anything in the black water tank other than toilet paper specifically made
for Recreational Vehicle systems.
• Do not put automotive antifreeze, household toilet cleaners or drain cleaners, or any
solid material into the waste water system.
• Always use chemicals in the black water system that are made especially for this
purpose.
• When cleaning components of the waste water system, use cleaners made for
Recreational Vehicle systems.
• Always keep the drain cap in place, and termination valves closed.
• After every third time the holding tanks are emptied, fill and flush both tanks with
clean fresh water a couple of times to keep them clear and clean.
