Close valve handle 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 Heaters - Optional
Your coach may be optionally equipped with
black water and grey water holding tank heaters
to allow use of water utilities in freezing temper-
atures. DO NOT operate the holding tank heaters
unless the shoreline cord is plugged into a 110-
volt source or the auxiliary generator is running
to recharge the house batteries. The chassis
engine alternator will also recharge the batteries
for use of holding tank heaters while driving
down the road.
NOTE: The holding tank heater pads are electri-
cal resistance type heating elements.
This type of heating element typically
uses a large amount of current while
operating. If the tank heaters are used
without a recharging source, they will
drain the house batteries in a relatively
short period. Typically, the batteries
would not support overnight heating
without a supplemental charging source.
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
Section 8 - Appliances
for further infor-
mation 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.
Water System Winterization Valve
Your coach is equipped with a manually
operated water line winterization system for
your convenience in winterizing fresh water
lines.
The system features a diverter valve and suc-
tion tube in-line between the tank and water
pump to draw non-toxic RV water system anti-
freeze into the water lines. This feature is located
near the water pump and drain valves. See page
