Sewage (black) tank preparation
It is important to add enough water to prevent solid waste buildup. Follow the
directions listed below and in the manufacturer's operator manual.
1. Release one to two quarts (1 or 2 liters) of water into the toilet bowl.
2. Follow the directions on your RV-approved toilet chemical bottle (customer supplied)
and put the recommended quantity of holding tank chemical into the toilet bowl.
Flush the toilet and allow at least two gallons (8 liters) of water to flow into the holding

tank.
Waste (grey) holding tank preparation
No special preparation is required, however, placing a small quantity of chemicals into this
tank, such as baking soda or an approved RV chemical, will reduce odors from food particles
in the system.
Cleaning and Maintenance
The toilet should be cleaned regularly for maximum sanitation and operational efficiency.
Use only RV approved chemicals. Do not use chlorine (undiluted) or caustic chemicals,
such as laundry bleach or drain opening types, in the toilet system. These products damage
the seals in toilets and dump valves.

Black Tank Flush

The black tank flush (no fuss flush) inlet is typically located on the utility center panel (if so
equipped) labeled as "Tank Flush". For models not equipped with a utility center, the inlet
is located on the side of the recreation vehicle. The location may vary depending on your
model. Attach a garden hose (connected to a pressurized fresh water source) to the black
tank flush inlet. The water goes directly into the black water holding tank sprayer connec-
tion, allowing you to remove debris and preventing accumulation. A check valve is incor-
porated in the plumbing lines to prevent back flow. Flush the black water tank each time the
grey and black water holding tanks are dumped or as needed.
™ NOTE: Utility center (if so equipped) valve positions do not affect the tank
flush function. It does not matter where they are positioned when operating
the tank flush.
™ NOTE: To help insure debris does not clog the tank sprayer orifices, use
"TANK FLUSH" every time the waste holding tank is emptied.
1. Dump the black water tank (see Gray Tank Drain & Black Tank Drain) and leave the
black tank drain valve open.
Connect a garden hose from the water supply source to the black tank flush.
2.
With the water source turned ON, flush the black water holding tank until the water

running out of the black tank drain valve is clear (not discolored or cloudy).
4. Disconnect the garden hose and close the black tank drain valve. Fasten the sewer hose
housing dust cap back on the tank flush inlet.
