the rear bumper storage compartment (see
Fig. 3), and the auxiliary holding tank dump
valve is located next to the sewage outlet
on the roadside main frame rail just forward
of the bumper. (See Fig. 4.)
To empty one or both tanks attach the
sewer hose by pressing the bayonnet fitting
onto the dump valve outlet and rotate
clockwise until it feels solid and secure,
(See Figs. 5 and 6.) Attach the outlet end of
the hose to the sewage outlet, making sure
that the hose is placed so it will drain
completely. The dump valves have two wire
loops that lock the handle in the closed
position. To unlock push outward on the
wire loops and they will snap loose, permit¬
ting you to open the valve. Pull up the
dump valve handle as far as it will go and
wait until the tank is drained. When dump¬
ing, the main holding tank should be
dumped first; then the auxiliary holding
tank. This will help to rinse out the sewer
line with auxiliary holding tank water.
The main holding tank must be flushed out
until all paper and waste material is re¬
moved. Close the dump valve and refill the
tank with 5 to 10 gallons of clean water and
repeat until clean.
On 27, 29 and 31 ft. rear bath models, a
convenient fitting for flushing the holding
tank is in the center of the rear trunk
compartment.
Replace the plug after using the fitting. The
sewer hose is stored in the rear bumper
compartment. Rinse out the sewer line
before storing.
When in a park and connected to a
sewer outlet,
keep the main holding tank
dump valve dosed and empty the tank
every few days or whenever it becomes
almost full.
Only by sending a large
volume of liquid through the main hold¬
ing tank at a time will toilet paper and
other soiids completely wash away.
This practice will avoid the accumulation of
solids in the main holding tank which could
lead to an unpleasant cleaning job. Should
solids accumulate and close the dump
valve, fill the tank about half full with water;
then tow the trailer for a few miles. The
turbulence and surging of the water will
usually dissolve the solids into suspension
so the tank can be drained. If your trailer is
equipped with the auxiliary holding tank,
keep the tank valve open when connected
to a sewer outlet.
The
Aqua Magic toilet
employs a sliding
self-cleaning positive seal blade. Odors
cannot escape from the holding tank into
the trailer. The unit uses less than 2 quarts
of water for automatic flush. A special fea¬
ture is the second pedal attached to the
main foot pedal which, when pressed by
itself, allows fresh water through either the
fill rim or hand spray without opening the
slide valve.
When conserving water,
use the hand
spray (See Fig. 1, page 78) in the following
way:
1. Hold the hand spray in ready position
