Training Information Point
If the flush valve fails in the open position, cabin pressure goes
through the open valve. You can use the manual shutoff handle
to close the manual shutoff valve. Pull the manual shutoff
handle to close the manual shutoff valve. Push the manual
shutoff handle to open the manual shutoff valve.
The FCU has a maintenance switch. Use the maintenance
switch to keep the flush valve open during maintenance
operations. Push the maintenance switch one time to open
the flush valve. Push the maintenance switch again and hold it
in for two seconds to operate the vacuum blower. The vacuum
blower operates for ten seconds and then stops. Push the toilet
flush switch to close the flush valve and return the toilet to
normal operation.
The toilet bowl has a layer of non-stick material. Do not let toilet
bowl cleaner fluid stay in the toilet bowl for a long period of
time. The toilet bowl cleaner fluid can damage the surface of the
toilet bowl.

Lavatory Flush Cycle Operation
The flush control unit (FCU) must receive an enable signal from
the logic control module (LCM) to operate the toilet assembly
components. The LCM sends an enable signal to the FCU when
the waste tank is not full.
If the FCU is enabled, the flush cycle will start with the operation
of the flush switch.
The flush control unit (FCU) controls the operation of these
components during the flush cycle:
* Vacuum blower
* Rinse valve
* Flush valve.
When you push the flush switch, the FCU immediately starts a
duty cycle inhibit. The duty cycle inhibit prevents another input
from the flush switch for the next 15 seconds.
The FCU also sends a signal to operate the vacuum blower. The
vacuum blower will operate if the airplane is below 16,000 feet
and the waste drain ball valve is closed. The FCU sends the
vacuum blower signal for 15 seconds.
One second after the flush cycle starts, the FCU opens the rinse
valve. The rinse valve is open for 0.7 seconds. During this time,
eight ounces of potable water goes into the toilet bowl. The FCU
then closes the rinse valve.
Two seconds after the flush cycle starts, the FCU opens the
flush valve. The flush valve is open for four seconds to drain the
toilet waste. The FCU then closes the flush valve.
The vacuum blower continues to operate for nine seconds. The
vacuum blower then stops.
The FCU is then ready for another flush cycle.
