VacuFlush: Get To Know The System

Welcome to learning more about your New, Current or Future VacuFlush system.

When comparing the major differences among marine toilet systems, most boaters find that SeaLand VacuFlush systems by Dometic offer many advantages that result in homelike comfort and superior, long lasting performance.





How The VacuFlush System Operates:

VacuFlush systems operate with fresh water, eliminating the mal odors and calcification build-up caused by lake and seawater organisms that die in the lines. It only uses an average of a pint of water per flush... allowing up to four times more holding tank capacity than other types of systems.

Vacuum is the most efficient way to evacuate the lines of waste. This cuts down the chances of permeation cause by sewage sitting in your lines, more common with other systems.

All this performance with adult size seats and very low power consumption from 3 - 7 amps. A boat with a VacuFlush system enhances the resale due to its long running reputation and reliability.

1. Vacuum is maintained in the system between flushes. Before use, the water level in the bowl can be raised by simply lifting the flush lever.

A vacuum pump is paired with an accumulation chamber (between the toilet and the holding tank). This pair is called the "Vacuum Generator". The tank chamber is where the vacuum accumulated is stored as the pump is pulling everything out of the line from your toilet. There is a coil resisted switch on the tank that gets pulled inward when the vacuum is accumulated (do NOT adjust the coil on this switch). Once the vacuum tank reaches 8-10 inches of vacuum, the coil will be pulled away from the trigger – turning your pump off.

2. When the toilet is flushed by pushing down on the foot lever, the vacuum energy stored in the system is released. The change of pressure in the vacuum tank releases that diaphragm on the switch - releasing that coil, and allowing it to activate the trigger. This will turn your pump on, pulling the flush from the toilet (through the vacuum generator) and pushing it to the holding tank.

3. After the flush lever on the toilet is released, creating a vacuum tight seal at the toilet bowl, the vacuum pump continues to run until the vacuum level is recharged in the system, as it is pushing the waste to the holding tank. Recharging the vacuum takes about one minute, depending on how long your run is. Once the vacuum is built in the system, the pump will turn off and it is ready for the next flush.

It is an all inclusive Pump and Accumulator unit.


VG3-LP (Low Profile Vacuum Generator) Is for those spots that your height is limited.
The Pump and accumulator are side by side.


Vacuum Pump & Accumulator Tank Is the pump separate from the accumulator tank
so you can place them in different locations if your space is limited.


3. A Holding Tank. Any existing holding tank will work just fine.
It is only a destination and does not interfere with the vacuum system itself.

________________________________________________

 

The optional DVS01 status panel gives you a green light that indicates the vacuum system is charged and ready to be flushed.
It also indicates with a red light that the vacuum has not yet been accumulated and the system is not ready to be flushed, 
or if the holding tank is full (if hooked up with a relay to your holding tank level indicator).

The optional DVS02 status panel gives you all those features, along with a convenient switch to turn the generator on and off when needed. 
This option is only to be used with pedal flush toilets, as the breaker in the switch is only 10 amps, and will malfunction if used with an electric VacuFlush toilet.
