EZ INLINE FILTER INSTRUCTIONS

Your EZ Inline Filter comes assembled ready to use. Each carbon cartridge is suitable for one batch of alcohol from a 25 L (6.6 US Gal) Still, or for 300 L (79.3 US Gal) of water, after which it should be replaced. It is a simple matter to replace the used cartridge, see assembly detail.

The unique EZ Inline Filter Carbon Cartridge is constructed from a specially formulated blend of carbons designed to deliver optimal performance. This blend of carbons has been selected with pore sizes ideal for removing impurities in distilled spirit or unwanted chemicals from water and is fast, clean and easy to use.

Mineral salts are present in the ingredients used for manufacturing activated carbon. If these are not flushed out they can be absorbed into the spirit. Later these salts can become insoluble in the spirit, especially at lower temperatures, and can form a fine sediment or haze. These salts are not dangerous, but you do not want them in your spirit as they can form crystals or haze in the spirit. This is why we recommend flushing the filter with clean water before use. If a haze forms it will sediment out over a few days and you can decant your spirit off. If this occurs you should increase the cartridge soaking next time.

Activated carbon is prepared in a manner which causes the carbon crystals to become porous and develop a very large surface area. One gram of activated carbon may have 500–1,500 m² of internal surface area. This large surface area and the many internal pores in the carbon are able to absorb many different chemical compounds including those which cause unwanted flavours in your spirit. The absorption process is very complex and depends on concentrations, molecular weight etc. In the case of alcoholic spirit, the process works best if the alcohol concentration is 50% or less. This is why we recommend adjusting the alcohol level before purification.

1. Soak the EZ Inline Filter Carbon Cartridge in a glass of clean water until the cartridge is fully submerged and air bubbles have stopped escaping from it. This is necessary to remove mineral salts from the carbon and flush out any carbon dust, You should do this for every new cartridge.

2. Connect the filter to the tap on the reservoir (not supplied) with a short length of clear PVC tube. The tube should not be more than 100mm (3.9") long.

3. Close the tap and add your spirit to the reservoir.

4. Adjust the alcohol level to under 50% with clean water. Check this with a spirit hydrometer or alcoholmeter.

5. Open the tap and allow the spirit to pass through the filter into a collecting pail.

After carbon purifying, the spirit should be watered down in strength to 40% ABV prior to drinking. We strongly advise against making higher strength spirit.

Example:

To convert 45% strength alcohol to 40% use the following calculation:

4.5 L (1.2 US Gal) x 45 / 40 = 5.06 L (1.33 US Gal)

If you collect 4.5 L (1.2 US Gal) of spirit and this measures 45% after carbon purifying, then multiply 4.5 x 45. Divide this by 40% and you will need to make
the total spirit up to 5.06 L (1.33 US Gal) with water. In other words add 590 ml (20 US fl oz) of water. This is a rough guide only. Watering down the spirit to
40%, or less, is very important as people not used to high strength spirit can easily overdose resulting in nausea and in extreme cases death.
