water to 3/4 full. This provides sufficient water
to allow complete flushing of waste material
into the sewer line.
Whenever possible, drain the holding tanks
before traveling. Wastewater and sewage in
the holding tanks reduces the carrying or cargo
capacity of the motor home. See the Motor
Home Loading chapter.
During extended or semi-permanent hook-ups
and the tank valves are left open to the sewage
systems, waste materials will build up in the
tank and cause serious plugging. In these cases,
keep the valve closed until the tanks are 3/4 full,
and then drain into the sewage system.
The holding tank drain valve outlet is to be used
with a removable termination fitting that locks
onto the outlet with a clockwise twist. Clamp
the sewer hose drain to this fitting. A protective
cap should remain in place when you are not
draining the tanks.
To drain the holding tanks:
1. Attach the sewer hose to the holding tank
outlet. Insert the end of the hose into the
sewer or dump station inlet, pushing it
firmly far enough into the opening to be
secure. In some cases, adapters may be
necessary or required between the line
and the inlet. Arrange the sewer hose so it
slopes evenly.
2. Electric Dump Valve (if equipped) - Drain
the black water holding tank first. Push the
dump switch up towards the word “open”
and watch for discharge down the sewer
hose. The valve will open in 1-2 seconds
and an LED light will come on. Do not
hold the switch for more than 2 seconds.
For other models drain the black water
holding tank first by pulling the “T” handle
out on the valve and watch for discharge
down the sewer hose.
3. Electric Dump Valve (if equipped) -
Allow enough time for the tank to drain
completely. When the tanks is empty push
the rocker switch to the “close” position.
Again the valve will close in 1-2 seconds.
The LED light will go out when the valve
is completely closed. Run enough water
(up to five gallons or so) into the tank to
cover the bottom. This will aid the break up
of solid wastes, and reduce “pyramiding”
of waste material. For all other models
allow enough time for the tanks to drain
completely. When the tank is empty push
the “T” handle “in” to close the valve
completely. Run water (approximately 5
gallons or so) into the tank so the bottom
is covered. This will aid in breaking up of
the solid masses that often form in the tank
and reduce the possibility of “pyramiding”
of the deposited solid waste.
4. To drain the gray water tank, repeat the steps
above using the other knife valve. This tank
is drained last to aid in flushing the outlets
and hose. The gray water knife valve may be
left open in a semi-permanent hookup.
5. See the tank flush system instructions in
the next section if your recreational vehicle
is so equipped.
6. Remove out the sewer hose and cap the outlet.
7. Rinse out the sewer hose with fresh water
and remove the sewer hose from the dump
station.
8. Replace sewer or dump station covers.
ELECTRICAL SYSTEMS
Battery Charging
Your motor home is equipped with AGM
sealed batteries. These batteries do not contain
electrolyte (fluid). They are designed to be
maintenance free with proper use
Please refer to the Owner’s Manual for further
information regarding the Battery Charging System.
CAUTION
The sewer drain valve must be open when using the
black tank flush inlet.
