TYPICAL VACUUM FLUSH SYSTEM
A vacuum style head uses a combination of vacuum suction and wa-
ter
fl ow from the fresh water tank to clear the head of waste. Before
using the system turn the head switch located in the head to the “on”
position at the main DC control panel.
Make sure that there is always a small amount of water left in the toi-
let head bowl. This acts as a trap and will reduce unwanted odors.
Before leaving the boat for an extended period,
fl ush the head for at
least 10 seconds. This ensures that waste has cleared the sanitation
transfer hose and has entered the holding tank.
Waste left within the transfer hose tends to dry out and harden. This
could restrict the internal size of the hose and hamper future opera-
tion. The system components including the hose are formulated for
the transfer of sanitary waste only. Do not allow the following items
in the system: Strong acid or caustics such as drain openers, petro-
leum solvents or fuels, alcohol based products such as antifreeze and
pine oil products along with sanitary napkins and baby diapers.
System vacuum is monitored by a switch located on the outside of
the vacuum generator’s tank. When the switch senses a vacuum drop,
it automatically signals the pump to energize and bring the vacuum
back to the operating level. This is normally a two minute process.
