11.2.3 DUMPING HOLDING TANKS
When dumping holding tanks:
1. Remove drain hose from
storage compartment.
2. Remove dust cap from drain
outlet. Attach drain hose
securely.
3. Place the other end of the hose
in sewer opening.
4. Make sure hose is lying flat.
Open black water valve with a
quick pull. Move hose about
gently to ensure flow of waste
materials. When tank is empty,
close valve.
5. After tank has been drained,
run several gallons of fresh
water into the black water tank
through the toilet. Open the
dump valve to flush out any
residual wastes. After the tank
has been drained again, close
the valve.

NOTE
Do not open the grey water valve until
black water valve is closed. This will
prevent any black wastes from entering
the grey water tank. Grey water also
rinses out any black water residue from
inside the drain hose.
IMPORTANT
Holding tanks should be dumped
before travelling to eliminate unneces-
sary weight while driving.
