Water Ionizer Instruction Manual
Hard-Plumb universal water connection The Masterpiece and Mavello Water Ionizers come with a Faucet Diverter that attaches to the faucet by removing the aerator from the faucet and screwing on the Faucet Diverter. You do not need to give up the use of your sink when you install your water ionizer. Once you have attached the Faucet Diverter to your faucet, you can continue to use the sink as you normally do, then divert the water into the Water Ionizer when you wish to use it by turning the handle on the Faucet Diverter. The Faucet Diverter that comes with your unit is a standard 15/16" (27 thread) male fitting, which fits most standard faucets. Everything else you will need will be included with the unit when you receive it.
If you have threads inside the faucet (female threads) you will need a 15/16" Male Adapter (27 threads - 9D). If the threads are slightly smaller than the 15/16" Faucet Diverter, you may have a 13/16" faucet in which case you will need a 15/16" X 13/16" adapter. The faucet diverter comes with 2 standard adapters which should fit most tap heads. You can also purchase other adapters from any hardware stores and they are very common items.
Basic Operation
Toyo Water Ionizers come with 3 feet (1 meter) of 1/4" plastic non-toxic tubing that connects to the Water Ionizer and is used for the acid Ionized Water tube which drapes into the sink. All Water Ionizers produce both Acid and Alkaline Ionized Water simultaneously, 70% of the water coming out the silver stainless steel flexible Tube at the top of the unit, 30% of the Water coming out of the plastic hosing from the bottom of the unit.
Where to Install Your Water Ionizer
Water Ionizers can be installed at any sink in the house, most commonly in the kitchen or bathroom. Toyo Water Ionizers can sit on the counter or can be hung from wall next to your sink. Two holes in the back of the units are provided for hanging the unit. Water Ionizers will not work properly if one attempts to operate it from underneath your sink.
Installation Time
Typical installation takes approximately 10 minutes and is not a difficult operation.
Toyo Water Ionizer Installation (without Pre-filters) Step 1: Screw in Stainless Steel tube to the top of the unit. Step 2: Remove aerator from the faucet and attach Faucet Diverter to Faucet. If you have threads inside the faucet (female threads) you will need a 15/16" Male Adapter (27 threads - 9D). Step 3: Cut plastic hose that comes with your Water Ionizer in half.
Step 4: Attach one hose to the Faucet Diverter using a hose clamp at the end of the hose to prevent leaks. Attach the other end to the bottom of the Water Ionizer marked INLET. 
Step 5: Place one of the hose clamps at the end of the INLET tube to prevent leaks. Attach the other hose to the bottom of the Water Ionizer labeled OUTLET and drape the tube into the sink.
Step 6: Plug the unit into an electrical outlet.
Step 7: Turn on the faucet and begin running water through the unit. The Water Ionizer will turn on automatically. 
Masterpiece Water Ionizer: The Masterpiece does not have an on and off button. Water pressure will turn the unit on. The unit will automatically go into cleaning mode for 30 seconds then switch to drinking mode. A song (Home Sweet Home) or a continuous beep plays when the unit is in cleaning mode and Acid Ionized Water is coming out of the stainless steel tube on top of the unit, and Alkaline Ionized Water is coming out the tube in the bottom of the unit. Never drink Acid Ionized Water. Mavello Water Ionizer: The Mavello has an ON/OFF switch in the back of the unit and a power button in front of the unit. Both must be turned on for the unit to work ( you should get green light when the front power button in ON ). The Mavello will automatically come on in cleaning mode and will remain in cleaning mode indefinitely until the unit is manually switched into drinking mode by pushing one of the 4 numbered buttons on the top half of the control panel. The cleaning mode will not automatically come on after that unless the water cell plates are dirty and the unit will automatically switch to cleaning mode. However if the front power switch is off ( red light) and then turn on each time you use the Mavello the cleaning mode will always come on automatically.
Toyo Water Ionizers Installation ( with Pre-filters)
If the house has an outdoor or garden filter to remove heavy sediments then the pre-filters are not required. For those houses where municipal water supply is dirty and there is no outdoor or garden filter then it is advisable to have pre-filters installed before the water ionizers. This means that the tube from the faucet diverter will need to connect to a pre-filter set ( either single or double filter type) instead of directly to the water ionizer. Simply put, the pre-filter set sits between the tap ( water source) and the water ionizer. The pre-filter will come with 2 connectors attached ( inlet and outlet). Care should be taken to ensure that the tube from the faucet diverter goes to the inlet connector. This is normally labelled clearly. The pre-filter will also come with 3-feet wider tube and a plastic cover opener. You should use the wide tube from the faucet diverter to the pre-filter set. Designer faucets
The most difficult faucets to attach a water ionizer are designer faucets. Often they are simply not suitable for use with a Water Ionizer because the fittings are of unusual sizes. If you are unable to find the proper fittings for your designer faucet, you may want to consider hooking up the Water Ionizer to another sink in your house or simply change to universal size faucet.
Hard Plumbing the Water Ionizer to Your Water Line
The term hard-plumbed means to attach the Water Ionizer directly into the water line instead of at a faucet with our Faucet Diverter. Plumbing supplies can be purchased at any hardware store, however, plumbing expertise will be needed for direct connection into your water line.
Universal Fitting
Toyo Water Ionizers come with a universal fitting that will allow you to attach the unit to many, but not all, types of faucets such as bar faucets that have no threads on the end of them to attach anything to. Please be aware, however, that this type of fitting quite often leaks and is not recommended for long-term use.
Other Possibilities for Connecting Your Water Ionizer
Besides hard-plumbing the unit directly into your water line, you can also attached your unit to a Gooseneck Faucet. This is a small faucet usually installed at right corner of the sink and is often referred to as a drinking water faucet. To use the water ionizer with this faucet, slip the end of the feed-line, which attaches to the INLET of the back of the unit, over the end of the faucet then secure it with a 1/4" screw-type hose clamp that can be obtained at any hardware store.
