EXTERIOR SHOWER
The exterior shower feature allows you to do
things such as rinse off sand or salt after a swim,
rinse off muddy boots, or bathe your pet outside
the coach. It is located in the utility system com-
partment.
WASTE WATER SYSTEM
(HOLDING TANKS)
The drainage system is self-contained and
uses two separate holding tanks to contain the
waste water until it can be dumped at an appro-
priate waste water disposal site. This means you
can use the toilet, sinks and shower even in areas
where utility hookups are not available.
The main holding tank contains the sewage
from the toilet, and is commonly called the black
water tank. The second holding tank contains the
waste water from the galley sink, bathroom lava-
tory and shower, and is commonly called the
gray water tank.
Dumping Holding Tanks
1. Remove drain hose from exterior storage
compartment.
2. Remove dust cap from drain and connect
drain hose. Be sure it is firmly attached.
3. Place the other end of sewer hose into dis-
posal opening.
4. Open the black water valve with a quick pull
and make sure there are no sags in the hose.
Move the hose gently about to dislodge any
waste and ensure complete drainage. Close
black water valve as soon as tank is empty.
NOTE: Do not open the gray water valve until
the black water tank is drained and dump
valve closed to avoid sewage back-up
into grey tank. Gray water also rinses
any black water solids from the drain
hose.
For your protection, this faucet is equipped
with a vacuum breaker (back flow preventer)
to prevent contamination of your potable wa-
ter supply. The water in the hand held shower
hose will drain through this vacuum breaker
when the faucet is turned off. This is not a
leak. This drainage is inherent in the design of
the vacuum breaker, and is evidence that it is
functioning properly.
