4800 series VacuFlush® Toilets
Quick-Start Instructions
PREPARE TOILET FOR USE
1. Turn on water supply and electrical power to toilet.
2. Disconnect toilet system discharge hose from waste tank or other treatment device
(if attached) and place discharge hose end outdoors or in water receptacle.
3. Flush water through entire toilet system by flushing toilet five times (press Flush switch
and allow each flush cycle to complete until green light indicates system is ready for next
flush). Each cycle takes about one minute.
4. Re-connect discharge hose to tank or other device. Toilet system is ready for use.
TOILET SYSTEM OPERATION
Add Water to Toilet
1. Press “Add Water” switch 1 .
More water may be desired when flushing 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 4 is lit, there is not enough
vacuum to complete a flush. Do not attempt to flush, or
a clog may occur.
With each flush, 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.
