SANITATION SYSTEM

Your trailer is equipped with a complete sanitation system. The components of this system
are the toilet, waste water and sewage holding tanks and drains for both tanks. Familiarize
yourself with all functions of the system. Read, understand and follow the information
found here as well as information in the "Set Up Camp..." chapter. If you have questions,
consult with your independent, authorized dealer for clarification.

Using Toilet and Tank System

.
NOTE: For added convenience and better sanitation system performance, it is
advisable to always have four to six inches (10-15 cm) of water in the toilet.
Prior to using the sanitation system, it is strongly recommended to flush the toilet several
times to release sufficient water into the holding tank. If there is not a sufficient amount of
water used during flushing, the waste materials may not evacuate properly from the drain
line to the tank. Clogged tanks and pipes could eventually occur.
The toilet system will perform better when water is run for ten to fifteen seconds after
flushing to ensure that the waste will proceed to the bottom of the tank. Unlike a toilet in a
home, which uses four to seven gallons (18-32 liters) of water per flush, the average
recreation vehicle system uses one to three quarts (1-3 liters).

Vents

Another important part of the sanitation system are the vents which release air from the
tanks. Each tank has a vent pipe built into the trailer through the cabinet, wall and roof. A
vent cap is attached to the roof and must be clear of obstructions to perform as intended. On
some models, the vent pipe may be part of the drainage system referred to as a "wet vent."
This means water flows downward as air flows upward in the same pipe.

Holding Tanks

The final part of your system are the holding tanks. They hold waste and are located below
the floor of your trailer. The bath tub and sinks drain into the waste water tank, also referred
to as the "gray" water holding tank. The toilet drains into the sewage holding tank, also
referred to as the "black" waste holding tank. Certain floor plans may also have the
lavatory draining into the waste (black) tank.

WASTE (BLACK) TANK PREPARATION

1. Release one to two quarts (1 or 2 liters) of water into the toilet bowl.
2. Follow the directions on your toilet chemical bottle, by placing the recommended
quantity of holding tank chemical into the bowl.
3. Flush the toilet and allow at least two gallons (8 liters) of water to flow into the tank.
Caution: It is important to add enough water to prevent solid waste build up. Follow
these directions each time after emptying your holding tank, except when
winterizing.

GRAY WATER HOLDING TANK

No special preparation is required, however, placing a small quantity of chemicals into this
tank, such as baking soda or an approved RV chemical, will reduce odors from food
particles in the system.
