4. Open the grey water valve. The water in the grey tank will flush remaining solids from the
sewer hose. The grey valve remains open until the next drain cycle, or time of departure.
WARNING:
Never operate the flush system unattended. Flooding may occur. Use the tank flush
system each time the holding tanks are cycled. Failure to routinely use the flush sys-
tem will result in a clogged spray nozzle. Turn off the water supply when finished
flushing the tank.
When preparing for travel:
1. Close black and grey valves. Undo restraining devices from the sewer hose. Disconnect
the sewer hose from the termination outlet by rotating the fitting counterclockwise 90º.
2. Drain the sewer hose using a hand over hand method while working the sewer hose
towards shore fitting. Rinse the sewer hose with outside facility and repeat the hose drain
process.
3. Remove the sewer hose from shore fitting. Install sewer hose in carrier and lock door.
Secure the termination cap (required by law in some states).
4. If desired, add chemicals to the tanks to control odor. Follow the directions given by the
manufacturer of the chemical.
NOTE:
Dump the black tank before driving.
Waste Pump (Optional)
The waste pump is a self-priming impeller pump designed to minimize clogging when draining the
tanks. The system comes with a 1-1/2" outlet hose with sewer pipe adapter and a 13 gallon per minute
macerator pump.
To Empty the Black Tank:
• Ensure the connector on the macerator pump to the
termination point on the dump connection is
secure. Ensure waste pump outlet hose is secure.
• Remove the drip cap at the bottom of the sewer
pipe adapter.
• Insert the adapter into the sewer connection.
• Open the solid (black) waste drain valve at the
plumbing service center.
• Turn on the macerator pump using the switch on
the service center panel.
• When the black tank is empty, turn off the pump
and leave the solid waste drain valve open.
