2. Open the desired black / gray (manual) drain valves,
one at a time (black then gray).
3. The macerator bypass valve will be pointing away
from you and is attached to the macerator pump.
The valve location is by design to prevent acciden-
tally engaging the bypass when system is operating
normally.
4. The bypass valve is normally open (handle is pulled
OUT).
To bypass the macerator, push the by-
pass valve
IN (turns off flow from the macerator
pump) allowing waste to flow out of the dump
connector under the trailer via gravity.
5.
When finished, close the main dump gate valve
under the trailer, along with the black / gray
dump valves. Disconnect the sewer hose from
the main dump connector and at the dump sta-
tion.
Black Tank Flush (if so equipped)
The black tank flush (no fuss flush) inlet is typically located on the
utility center panel. The location may vary depending on your mod-
el. The inlet color may be either white or black. 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 hold
-
ing tank sprayer connection, allowing you to remove debris and pre-
venting accumulation. There is a check valve 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.
1. Dump the black water tank (see
Gray Tank Drain and Black
Tank Drain
) and leave the black tank drain valve open.
2. Connect a garden hose from the water supply source to the
black tank flush.
3.
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.
Tank Flush Inlet

The black tank drain valve must be OPEN any time there is a hose (water
supply) connected to the black tank flush.
 Do not leave any hose (water supply) connected to the black tank flush
when it is not in use.

Do not use the same hose to fill your fresh (potable) water tank that is used for
the black tank flush.
