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.
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
few gallons of water and 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 by
practicing 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.
Sewage Tank Rinse
To aid in maintenance and cleaning, the sewage tank on your King Aire is equipped with a “Sewage Tank
Rinse”. This system uses a specially designed spray head permanently located in the sewage tank that
cleans the inside of the tank when a water supply is connected.
