2. Leave Black Waste Tank Drain valve open
while flushing tank.
3. Attach a garden hose from a city water
hydrant to the Black Waste Tank Flush Inlet
fitting on the left sidewall. (This inlet is
clearly marked separate from the City Water
inlet).
4. Turn the water on to begin flushing. Allow
water to run for about three minutes.
5. Disconnect garden hose from flushing system
and close Black Waste Tank Drain valve.
Using On-Site Sewer Hook-Ups
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
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
accidentally happen, disconnect the hose, fill the
tank about half full with water, and drive a few
miles to dislodge the solids. A few starts and
stops will aid in the process. Then reconnect the
hose and drain in the normal manner.
NOTE: Always keep sewage drain outlet capped
while sewage connection is not in use.
Holding Tank Level Indicators
See “Systems Monitor Panel” in Section 4 –
Appliances for further information on the
monitor panel and checking tank levels.
See “Specifications” in Section 1 –
Introduction for tank capacities for your model.
HOLDING TANK HEATER
–If Equipped
Your coach may be equipped with black water
and gray water holding tank heaters to allow use
of waste utilities in freezing temperatures. The
holding tank heater power switch is located near
the monitor panel. The illuminated switch will
glow when the power is on.
DO NOT operate the holding tank heater
unless you are providing a supplemental 12-volt
power source to recharge the house batteries.
This means either the shoreline cord must be
plugged into a 120-volt source, the auxiliary
generator must be operating, or the chassis
Service inlet access must be closed when
utility connections are not in use.
