water dump valve with a quick pull. Close

NOTE: We recommend that you dump all hold-

ing unnecessary weight.

Flushing your Black Water Holding

Tank

The black water holding tank is equipped

with an internal spray head that allows you to

rinse the inside of the tank with a shower of

clean water after dumping.

1. Dump your black water holding tank in the

usual manner at approved sewage disposal

station.

2. Leave black water dump valve open while

flushing tank.

3. Attach a garden hose from a city water

hydrant to the Flushing System inlet fitting

in the water system compartment. (This inlet

is clearly marked separate from the City

Water inlet.)

4. Turn the water on to begin flushing; allow

water to run for about three minutes.

5. Disconnect hose from flushing system fitting

and close dump valves.

USING ON-SITE SEWER HOOK-UPS

The drain hose may remain attached to the

dump outlet and be routed out the bottom of the

compartment while the motor home is parked and

connected to an on-site sewage hook-up.
