TOILET SYSTEM OPERATION
Add Water to Toilet
1. Press “Add Water” switch 1.
More water may be desired when ushing solids.
Flush Toilet
1. Press “Flush” switch 2.
2. Flush toilet only when green “OK to Flush” indicator 3
is lit.
3. If “Do Not Flush” indicator 4is lit, there is not enough
vacuum to complete a ush. Do not attempt to ush, or
a clog may occur.
With each ush, a powerful vacuum force pulls waste from
toilet, through the vacuum generator, and into the waste
tank or treatment device. Using very little water, waste is
fragmented during discharge.
The vacuum generator brings the system vacuum back to
operating level in about one minute.
