NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste Tank
Drain valve until the black tank is
drained and dump valve closed to avoid
sewage back-up into gray tank. Gray
water also rinses any black water solids
from the sewage drain hose.
5. Open the Gray Waste Tank Drain valve. Be
sure there are no sags in the hose to ensure
complete drainage. Press and Hold Waste
Pump switch until tank is empty (do not run
pump dry.) Close Gray Waste Tank Drain
valve as soon as tank is empty.
NOTE: Sound of Waste Pump will change
significantly when tank is empty.
6. Store sewage drain hose.
7. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV stores.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
Flushing Your Black Waste Holding
Tank
The black waste 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.
