DUMPING HOLDING TANKS
1. Remove drain hose from exterior storage
compartment.
2. Remove dust cap from drain and connect
drain hose. Be sure it is firmly attached.
3. Place the other end of sewer hose into dis-
posal opening.
4. Open the black water valve with a quick pull
and make sure there are no sags in the hose.
Move the hose gently about to dislodge any
waste and ensure complete drainage. Close
black water valve as soon as tank is empty.
NOTE: Do not open the gray water valve until
the black water 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 drain
hose.
5. Open the gray water valve. Be sure there are
no sags in the hose to ensure complete drain-
age. Close gray water valve as soon as tank
is empty.
6. After both tanks have been drained, run sev-
eral gallons of water into the sewage tank
through the toilet. Then open sewage dump
valve and drain the tank again. Close valve
and replace dust cap securely.
7. It is advisable to add an odor control chemi-
cal to the sewage holding tank. These chemi-
cals are available at most R.V. stores.

8. Rinse sewer hose thoroughly with water and
stow.
NOTE: We recommend that you dump all hold-
ing tanks before traveling to avoid carry-
ing unnecessary weight.
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.
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
with the liquids when the dump valve is opened.
If the valve is left open, the liquids will drain off,
leaving solids in the tank. Should this accidental-
ly happen, disconnect the hose, fill the tank about
half full with water, and drive a few miles to dis-
lodge the solids. A few starts and stops will aid in
the process. Then reconnect the hose and drain in
the normal manner.
HOLDING TANK LEVEL INDICATORS
The holding tanks may be monitored on the
wall mounted monitor center.
Press the "Levels Test" switch to check the
level in each tank.
See pages 8-5 and 8-6 for further information
on the monitor panel.
WATER LINE & TANK DRAIN VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motor home for storage or
when sanitizing the water system.
To open or close the drain valves, turn the
handles in the directions indicated by the follow-
ing illustration.
Drain valve locations are listed on the follow-
ing pages.
