After your Xerolet System AOWTS has been installed by a CERTIFIED XEROLET PRO-DEALER the unit will require programming using the Control Panel. Your Xerolet Pro-Dealer will ask your preferences such as how many times you want to flush before a dehydration cycle begins and what time of the day you wish a dehydration cycle to begin every day without concern for the number of previous uses. After programming the unit your Xerolet Pro-Dealer will test the system and certify it for use.

Push the “ FILL ” button on the control panel to add water to the bowl prior to use if you desire. However, doing so will reduce the number of flushes before a dehydration cycle begins and increase your energy costs.

After using the toilet, close the lid and push either the “DRY FLUSH” button or the “ FLUSH ” button on the Control Panel.

When the toilet is flushed, the dump valve opens and the vacuum pump turns on creating negative pressure in the Dehydration Engine (DE). This helps to evacuate the waste and odors from the toilet bowl into the dehydration engine.

Motorized paddles inside the DE begin turning during the flush cycle to help pull waste down into the DE.

When the dump valve opens during the “FLUSH” cycle, spray jets turn on for one to two seconds to clean the bowl (using one cup of gray water from the infusion tank) then the dump value closes. No water is used to rinse the bowl during a "DRY FLUSH".

The dehydration cycle begins automatically after 10 flushes or when programmed to start during your preferred time intervals. There is a heavy use “ OVERIDE” function for those times when the toilet will be used more frequently. Simply press and hold the OVERIDE button on the control panel until the display shows the unit has entered the heat mode. You may use the toilet without any wait time between flushes. The DE will shut down automatically when the dehydration cycle has completed.

During the dehydration cycle the waste is heated to 255 degrees F inside the DE and kept at that temperature for no less than 10 minutes. Once all the waste inside the DE is dehydrated and all liquids are evaporated, the DE will cool to ambient temperature.

The vacuum pump on the Infusion Tank draws steam out of the Xerolet DE during the dehydration cycle and mixes the steam with ozone and gray water and passes through an ultra-violet light. This function eliminates smells, reduces BOD and COD, and oxidizes or living organics.

When the DE cools to ambient temperature the vacuum cleaner system automatically turns on and the bacteria-free dry powder is drawn into the vacuum bag for disposal into the household trash.

If your Xerolet has an optional internal vacuum system then the vacuum bag holds approximately two rolls of toilet paper before the bag must be changed. If your Xerolet is connected to a central vacuum system then you would change the vacuum bag when it is full. An LED light labeled “ VAC ” on the control panel will blink when it is time to empty the bag on either vacuum system. The powder that results from the dehydration process is safe for disposal in your household trash.

The standard Infusion Tank is about 2' tall and about 4' long and can be installed in a basement, garage, crawlspace, attic or wherever the most convenient location may be to run the necessary water lines, electricity and phone connection needed to operate the Xerolet AOWTS. Larger tanks will be needed if garbage disposals are used to discard uneaten food.

The Infusion Tank serves two main purposes: it settles out solids found in gray water from your sinks, shower, or washing appliances similar to the way a septic tank does and also sanitizes the gray water. All gray water from sinks, showers and washing appliances will first enter the digestion tank area of the Infusion Tank. This allows any sediment or organic particles to be separated from the liquid. These particles naturally breakdown overtime and are collected and stored in the digestion tank. This solid matter will need to be vacuumed out of the digestion tank when the tank fills and disposed of according to local ordinances. We recommend minimizing food disposal into the sink's garbage disposal system to prolong the time intervals between empying the digestion tank.

The gray water flows from the digestion tank into the Infusion portion of the tank where the liquid is sanitized with ozone and passed through a UV light to oxidize any organics, eliminate smells and reduce BOD and COD that might exist. This process actually sanitizes the gray water sufficiently for safe discharge into the environment.

Based on local climate conditions the excess sanitized gray water that accumulates in the Infusion Tank may be discharged into landscape vegetation or a drain field. Drain fields are designed to meet your specific site conditions and State or local regulations for sanitized gray water dispersal. (See the links for local ordinances)

Drain fields are designed based on peak flow from the house and the ability of the receiving soils to percolate. This is a site specific parameter that has to be determined for each installation site. Drain fields can be shared by multiple users. The specific type of drain field will be determined based on site conditions and cost. Because of the high quality of water being discharged new and cheaper methods of disposing of the treated gray water will be developed and approved in the future.

Where homes have existing septic tanks and drain fields that have failed it is possible the Installer can pump the discharge from the Infusion Tank directly into the existing system. Because the Xerolet System discharge is free of solid waste and contaminates it is likely a failing drain field will clear up and last for many years more.

Each component in the Xerolet AOWTS is connected together through a controlled area network or CAN-BUS that actually monitors all operating systems within the entire AOWTS. The system monitor is controlled by a Central Micro Processor we call “The Little General”. The Little General monitors all functions and if any part of the system fails the Little General will send a text message or e-mail through your phone line or internet connection to a local service provider, the owner, and if required to the Department of Health. Once the system has been repaired the Little General sends another message updating the status. The unique design of Xerolet's monitoring system allows access to complete data history for each AOWTS and can be sorted by specific areas.

The Xerolet AOWTS was built and tested to meet or exceed all standards and protocols set forth by American National Standards Institute, International Code Council, national Conference of States on Building Codes and Standards, National Fire Protection Association, U.S. Department of Housing and Urban Development,
National Sanitary Foundation International, and Underwriters Laboratory.

The Torch shown  is over 1000 degrees F and was put on the insulation shroud sample for about 1 minute. The material did not burn, melt or allow any significant heat to pass through it.
