Note:
Whenever you don't want to hear the toilet's vacuum pump operating, such as
at night, you can temporarily shut it off using the Toilet switch. This switch is
located on the Port Bulkhead. Placing the switch in the OFF position shuts off
the toilet's vacuum pump.

To operate the vacuum flush system:
1. Confirm DC power available at DC Control Panel - Helm.
2. On the DC Control Center - Engine Room, make sure the Electric Head
circuit breaker is ON.
3. Check the tank monitor located on the DC Panel - Helm. If the indicator
shows that the waste tank is at least ¾ full, it should be emptied. If
the tank level is ok proceed to the next step. There is another warning
light in the head that if lit, indicates the waste tank is at least ¾ full and
should be emptied. If the red indicator is not lit, proceed to next step.
4. Press the foot pedal at the base of the toilet. This flushes the toilet.
5. If the toilet bowl is dry, water can be added to the bowl by lifting up on
the foot pedal. This will add water without flushing.
It is common for vacuum systems to gradually lose vacuum pressure.
When pressure in the system drops below a predetermined level, the
vacuum pump engages automatically to bring vacuum pressure back to
the optimum level.
