WARNING
Holding tanks are an enclosed sewer system and must be drained into an approved dump station. Both black and gray
water holding tanks must be drained and rinsed thoroughly on a regular basis in order to prevent the accumulation of
harmful or toxic materials.
Whenever possible, drain the holding tanks prior to traveling. The carrying capacity of your unit will be reduced
if water is left in the black or gray tanks. The holding tanks should only be drained when they are at least 3/4 full.
Doing this provides sufficient water to allow the complete flushing of waste materials in the drain lines and hose.
If the tanks are not 3/4 full, add enough water to allow for sufficient flushing.
To empty the waste water tanks, connect the adapter to the drain hose. Use the adapter supplied with your unit. If
the adapter is lost or broken, one can be purchased from any RV supply store. Once you have placed the adapter
on the drain hose, it can remain there for the life of the hose. One end of the hose threads up through the hole in
the bottom of the service compartment, and the other end of the hose feeds into the sewer at the dump station.
Unscrew the cap off the drain. Connect the hose with the adapter in place to the drain fitting. Open the gate valve
all the way by pulling on the T-handle. The tank will start to drain as soon as the T-handle is pulled. After you
have drained the black water tank, immediately drain the gray water tank. Doing this helps to flush the black
water from the sewage hose.
When both of the tanks are empty, flush them with a fresh water rinse before you close the valves. The gray tanks
are easily flushed by pouring a couple of gallons of water into a sink drain. The drain outlet is engineered for
quick release of the drain hose adapter. Always close the gate valves and secure the end cap to prevent leakage
while in transit. After draining the black water tank, it is recommended to add a holding tank deodorant (such as
Thetford Aqua-Kem) to help control the odor and break down the solids. Follow the instructions given on the
holding tank deodorant package.
When using dump stations for draining the holding tanks, please keep other travelers in mind. Practice good
housekeeping. Leave the dump stations in good order. Above all, do not pollute.
Camping with Sewer Hook-Up
When camping at parks with sewer hook-up, it is important to keep the black water holding tank gate valve closed
at all times, except when dumping. The gray tank can be kept open while hooked to a sewer connection but again;
the black water tank must be kept closed. This is done so that an ample supply of liquid remains in the tank to
provide a smooth flow through the gate and drain valve when dumping. Sufficient liquid in the tank causes a
swirling action that should take any accumulated solid wastes with it. Accumulation of solid wastes in the black
water tank can be avoided by keeping the gate valve closed when connected to the sewer hook-up. If the valve is
left open, solid wastes may accumulate in the tank. This may eventually result in costly repairs.
CAUTION
The gray tank valve must be in the open position when operating the optional washing machine.
No Fuss Flush
This unit may be equipped with a flushing system for the holding tanks. When draining your sewer tank, attach a
water hose to the sewer spray hookup. After the tank is drained,
leave the gate valve open
and open the water
valve to allow water to spray inside the sewage tank. This will clean the inside of the tank of any debris that may
