Operating Manual


Safe Operation

  • Protect the machine from liquid spills; Lye and also alkaline water from the filter cup (the metal flask in front of the machine) can damage the surface and cause stains, especially on the front of the machine. The clean metal is protected by a varnish spray but it is still better not to get lye on it. A cloth can be used to protect the finish. 
  • Inside the machine and for the filter cup use only water low in ions, e.g. distilled or de-ionized or reverse osmosis water or clean rain water. Chloride ions in other water can be oxidized to harmful chlorine gas.  
  • Always use a funnel to fill up via the filler inlet on top of the machine. Keep the machine and bench dry as liquid on or under the machine may cause an electrical hazard.
  • Preferably fill containers away from the generator to avoid damaging spills.
  • NEVER allow the generator to run low on water as this could causer internal damage. Do not overfill. Fill slowly and only to just below the top waterline. 
  • Except for using Lye solution as needed, top up only with water low in ions.
  • Keep generator and gas outlet away from any flame, heat source or possibility of an electrical spark.
  • The machine needs good airflow during operation. Do not use it close to obstructing items or in a small enclosed space. 
  • After shutting down the machine slightly open the top filling cap.
  • After about 100 hours of use or about a month or two, depending on frequency of use, clean the lye solution in the generator, see below. 


Filling the Generator

Use appropriate safety equipment: rubber/plastic gloves, apron and eye protection as recommended for cleaning drains with caustic soda. Have a container of vinegar handy to immediately neutralize any caustic spills.

Fill a 1 litre jar 75% full with low-ion water. Slowly while stirring add 50 to 60 grams of sodium hydroxide (NaOH) as powder, pearls or crystals (e.g. sold as Drano or Caustic Soda). Allow the solution to cool.





Remove the cap on top of the machine and, using a funnel, fill into the tank. Check the sight tube often while slowly pouring Lye into the tank to avoid overfilling as it takes several seconds for the water level to register true. Add more low-ion water to just below the top waterline. Replace the cap.

When the machine is working the produced gas will raise the water level somewhat. Check the water level of the generator before switching it on.

Wash all items till the slippery feeling is gone.


Filling the Filter Cup

Unscrew the metal filter cup attached to the front of the machine by hand. The O ring seal requires only good contact and gentle pressure; it does not need to be excessively tight. Push one of the bubble stones into the bottom of the gas outlet pipe. Fill the filter cup about half full or with about 120 ml of low-ion water. This is to remove lye carried over by the gas. Pour this water back into the generator when you know from experience that it will not exceed the top water line and pour it back into the generator tank.  

Washer and Bubbler

The supplied washer, sometimes also called humidifier, to purify the gas still further is a jar with 2 openings in the lid for a hose coming from the metal filter and doing to the bottom of the bottom of the washer. You may push one of the supplied bubble stones into the end of this hose. Connect the other end of this hose to the metal filter cup. The gas outlet hose goes to the bottom of the bigger bubbler which is used for making energized water. Fill the washer about 60% with water free of chlorine and fluoride. Renew this water weekly or monthly depending on usage. while the bubbler may be filled closer to the top with good water containing some minerals, or otherwise add ½ teaspoon of unrefined rock or sea salt. 

To the connector end of the outgoing bubbler hose you can now attach either the supplied nasal cannula or a longer hose. This can be used to bubble more water in a glass container or for inhaling through the mouth or for skin treatment or to fill the leg or arm bag. The washer and bubbler hoses are supplied already pre-assembled. Between the Bubbler and the Washer is a red one-way valve. 

Bubble Stones: The grey bubble stones are sintered carborundum and preferable to glued stones. Best keep bubble stones after use submerged in water. If you want to dry one out, submerge it in distilled water and blow BG through for a few seconds to prevent minerals from clogging up the pores. Keep a clogged stone for some time in hot water. A fourth bubble stone has been supplied as a spare. You can operate the system with or without bubble stones as you prefer. The same amount of BG is probably absorbed in the bubbled water with either method as the stronger gas flow and surface agitation without bubble stones makes up for the smaller bubble size. 


Operation and Maintenance

Within a few seconds of switching the power on you will see strong bubbling. The ampere meter usually shows 8 to 20 Amp, depending on the amount of lye in the generator. If the bubbling is weak, check for any leaks. The washer or bubbler lid or the filter may not be tight enough. Check that there is no kink in the hose coming out of the washer which may obstruct the gas flow. 

If the Ampere reading should become very low and the bubbling noticeably slows down, the electrolyte in the generator needs to be cleaned. This is usually due to oxidized metal from the stainless steel electrodes carried along with the gas and blocking the internal pressure control. This then causes the electricity supply to the generator to be reduced. To avoid this happening it is recommended to clean the generator after about 100 hours or every one to three months of use.

Put a large plastic bowl in a sink, bathtub or other safe place. Remove the filter cup and open the cap on top of the machine. Use protective safety gear. Turn the machine upside down to empty the lye into the bowl. Then put about half a litre of tap water into the generator and shake strongly from side to side. Immediately empty and discard this liquid. There will be black oxides coming out. Repeat this procedure until the water is clear. 

The liquid in the bowl will soon clear up as impurities settle down. You can now decant the clear liquid into a jug and pour it back into the generator. To keep up the concentration of lye dissolve a teaspoon or 5g of caustic soda in some low-ion water and use this to fill the machine to just below the top waterline. Once a year discard all of the old lye and refill with new Lye solution. 


Description and Specifications

The LotusHydroCare is a Brown’s Gas Generator that has been adapted for health applications by converting a Chinese welding machine, called a Ving H160. As a welder the H160 operates at high pressure from 13 PSI (90 kPa) to 15 PSI (103 kPa), while pressure is released when it goes higher than 20 PSI (138 kPa). 

The LotusHydroCare operates at about 1to 2 PSI while pressure is released when it reaches 10 PSI or 69 kPa). This makes the LotusHydroCare safer for health applications.

Water consumption 25 ml/H, Weight 7 kg, Dimensions 450 x 280 x 360 mm



Brown’s Gas (BG, also called HHO or HydrOxy), has three specific health components: hydrogen gas, oxygen gas, and a type of bioenergy; for details see ’Brown’s Gas for Health’ at http://www.health-science-spirit.com/BG.pdf.

While drinking bubbled water or inhaling BG directly helps to energise the whole body, for healing a specific part of the body, BG is much more effective if applied directly or as close as possible to this part, in addition to inhaling it or drinking energised water. The main systemic effect is a noticeable increase in general energy, especially for individuals who are usually low in energy.

BG works much faster for healing accidents and injuries than for chronic problems. The reason is that with chronic problems there are usually additional issues that need to be cleared up such as eliminating microbial infestations, supplying deficient nutrients, improving defective enzyme systems, or removing toxins from the area.

Nevertheless, in all cases it is much easier to get results if there is plenty of energy, but without attending to these other items as well, energy alone helps only much more slowly. It is a common feature of health improvement that there are temporary cleansing or detoxification symptoms, usually involving pain and inflammation. Inform yourself about these issues.

Another important factor is your mind. As with all healing methods you need positive expectations. But in addition you can do more. You can use your mind to channel the BG energy into a particular organ in need of healing and use imagination of how you want the diseased part to look, feel or function. Used together, energy and imagination are many times more effective than using just one on its own.   

BG can be used in several ways such as drinking bubbled water, inhaling the gas, spraying it on the skin, hair and eyes or into a body opening, and filling plastic bags pulled over arms and legs. It is also good for pets, plants and fish. You may experiment to see what works best for you or to invent additional methods.


1. Drinking BG-bubbled water

The colder the water is the more gas is dissolved and retained. Therefore it is best to bubble into refrigerated water and afterwards refrigerate in a closed glass container. The usual bubbling time to charge a 1 L container of water is about ten minutes or 5 minutes for a glassful. It does not hurt to bubble stored water again for a few minutes just before use. 

You may also energize other liquids, such as commercial juices or juices that were frozen or refrigerated for some time, or milk, cold tea etc. In some liquids the bubbles form much foam that you may ingest. You may use energised water for blending fruit and vegetables, washing or sponging your skin and hair, bubbling into a foot bath or bathtub, you can use it for your animals or for watering plants.

The higher the water is in sodium and calcium ions and the more alkaline it is, the more bio-energy is being retained. However, alkalinity also causes calcium salts to fall out, therefore in alkaline water the calcium content may need to be restricted. You may use good mineralised water free of chlorine and fluoride such as spring, bore or filtered water, or add natural salt, e.g. ¼ to ½ tsp/l of unrefined sea salt, Himalayan salt or rock salt, to low-ion water.  


2. Inhaling the Gas

You may inhale the gas coming out of the washer by using a nasal cannula or you may attach the long hose to the washer and keep it in the mouth. The optimal duration for inhaling BG is not yet known but it is definitely advisable to start with a short time, e.g. several minutes, and increase only gradually. Initially individuals tend to experience more energy, but then get used to it after a few days. 

If used in the evening this may initially make it difficult to fall asleep. Individuals may breathe BG for several hours a day while working at the computer, watching TV or video, or reading. However, it is more beneficial to inhale BG in several shorter intervals rather than in one long piece. 

Three in One: Here is a way to combine three treatments at the same time: bubble water in a container with a large opening. Fill it close to the top and bend your face over it so that from the nose up it is over the opening. Inhale through the nose and exhale outside the container through the mouth. Keep your eyes open so that they, as the rest of the face, are bathed in a fine spray from the bursting bubbles. Afterwards you can drink the bubbled water.

Alternate Nostril Breathing: This is a yoga method to increase energy and harmonise or balance the energies of both sides of body and brain. Doing this exercise with BG can be expected to provide even greater benefits. Place the hose coming from the washer at the opening of the right nostril while closing the left one with a finger. Inhale slowly and deeply. Remove hose and finger, close the right nostril and exhale through the left nostril. Now move the hose to the left nostril and inhale while keeping the right nostril closed. Exhaling through the right nostril finishes one round. Do ten to twenty rounds, possibly several times daily. 


3. Topical Treatment

In addition to using energised water for external applications you can also use the gas directly by spraying it on the skin or into a body opening, or by filling plastic bags pulled over arms and legs. In these cases be mindful that the gas initially tends to flow upwards. So when filling a bag pulled over an arm or leg, keep the opening at the lowest point so that the whole bag can fill up. When using a bag do not walk around to avoid sparks from static electricity on carpets or door handles.

You may also put the end of the hose into a funnel pressed unto the skin and let the gas flow upwards through the funnel. You can let BG flow into an ear canal or into the vagina. It is not advisable to put gas into the rectum as this may cause bloating. 

Another useful method, especially for treating back problems, is to cover the problem area with a moist sponge or cotton covered with plastic, or just with a hollow hand, push the hose outlet under the lowest part, and keep the cover in place with light pressure as by leaning back against a pillow. Check the bubbling in the washer or bubbler to see that you have not blocked the outlet.
