WASTE WATER STORAGE AND DUMPING SYSTEM:

Your vehicle is equipped with a waste water storage and dumping system that will provide adequate and
effective storage and dumping of waste water. Your vehicle should be as level as possible to allow optimal
operation of the system.
CAUTION: Ensure that both the black and grey water gate valves are closed (inward position) before
using the waste water system. This applies especially after extensive driving. Black and grey water dump
valves are accessed through the small access door located just to the rear of the driver side door.

Waste Water Tank Preparation:

Your vehicle is equipped with two waste water tanks; the grey waste water tank is for waste water from the
sink and aisle shower and the black waste water tank is for sewage from the toilet. Both tanks are
equipped with separate dump valves so that each may be dumped independently. Before use of either
waste tank, be sure to read instructions provided by the toilet manufacturer regarding waste water
chemicals. We suggest that such chemicals be used every time to minimize build up of solids on water
level sensors inside the tanks.

Waste Water Tank Dumping:

Waste water tank contents must be dumped in authorized facilities only. To completely clear the waste
water tanks of all solid material, tanks should be full to provide the necessary volume required for complete
dumping. If you wish to dump a partially full tank, it is advisable to fill the remaining volume with water first.
Also, to completely clear the tanks of all solid material, tanks should be dumped immediately after road
travel while tank contents are unsettled.
Your vehicle is equipped with a dual black waste water tank system allowing you to use the interior black
waste water tank under moderate subfreezing conditions, see diagram page G.14.
The two tanks are connected together using a three inch gate valve accessed behind the 40% (rear) side
cargo door, see Picture G-P5. The interior black waste water tank can be emptied into the exterior tank by
opening the gate valve. For proper drainage the interior waste water tank needs to be full, so only empty
when the monitor panel indicates the tank is full. If you wish to dump a partially full tank fill the remaining
volume with water first. Waste water tank preparation (listed above) should be followed after each interior
black waste water tank discharge. Interior black waste water tank maybe emptied into the exterior black
waste water tank approximately two times before dumping is required.
CAUTION: Ensure gate valve is closed before closing cargo door, to avoid breakage.
CAUTION: During winter use (under moderate subfreezing conditions, refer to page G.9-G.12 antifreeze
is required when dumping the interior black waste water tank into the exterior black waste water tank. The
exterior black waste water tank must be dumped immediately to prevent freezing damage. Antifreeze
should be used at a 50-50 ratio.
