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 and
press and hold the Waste Pump switch.
Release the Waste Pump switch and close the
Gray Waste Tank Drain valve as soon as the
gray tank is empty.
NOTE: Sound of Waste Pump will change
significantly when tank is empty.
6. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV stores.
7. Rinse sewage drain hose thoroughly with
water and stow.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.

The sewage drain hose may remain attached to
the sewage drain outlet while the motorhome is
parked and connected to an on-site sewage hook-
up.
When using a sewer hook-up, keep the dump
valves closed until a tank becomes full or when
preparing to leave the site. This keeps the solids
in suspension, allowing them to be carried out
