Your drinks pressure cask can be
used for a number of purposes:
Stainless steel pressure cask (unpacked)
tapping unit (A) (cardboard box) comprising:
stainless steel connection with seal,
manometer (0-15 bar),
type-tested safety valve (prevents permissible operating
pressure of 10 bar being exceeded; this safety appliance
must not be manipulated!),
stainless steel riser-pipe as top-feed with ball-valve, blind
plug for use as gas-set connection.
-
Gas-set consisting of coupling unit (1) for connection
between cask connection and pipe; pipe (2), quick-screwconnection (3) as connection between pipe and pressure
reducer, seal and teflon tape
pressure reducer for CO²
2-kg gas bottle (CO² / carbonic acid)
cleaning rod.
Application 1: fruit juice with any desired level of alcohol content
The cask is used without connecting the gas bottle and additional fittings. In this way, you can use your cask simply and without any additions in a useful manner.
No accessories are required! Blind plugs at position 0 must not be removed!

If you want a clear fruit juice with a lower alcohol content, it is recommended to allow the juice to settle in another container for 3 - 4 hours after pressing to
separate suspended solids from the juice. All rotting fruit must be sorted out before the pressing stage.
Fill your SPEIDEL pressure cask after the pressing stage or after settlement immediately with the appropriate fruit juice.
Now you can decide what alcohol content you want your drink to have. If you close the cask immediately after filling it, you will later have a fruit juice with a low
alcohol content. The longer you leave the cask open, the longer the fermentation can continue, raising the alcohol content in the drink. If you leave the cask open
to fermentation for three or four days, for example, and only then close it, you will obtain a result with a higher alcohol content. You should however take care not
to let the juice ferment out completely, as there will then be no residual sweetness left in the drink, and you will also need additional fittings for removing the juice
from the cask (cf. application 3).
As soon as you close the cask, pressure will build up independently with fermentation until the pressure built up by the fermentation slows it down. This
application will give you a fruity drink whose alcohol content will alter slightly over the course of time with repeated drawing. The drink will retain its freshness in
the cask.
Application 2: low-alcohol fruit juice
The pressure cask is used with the addition of gas set, pressure reducer (CO²) and gas bottle (carbon dioxide) - see accessories. For using it with a gas connection,
please read the section "This is the right way to gas the cask".
When making a low-alcohol drink, you must pay special attention to hygiene and to the quality of the fruit you use. Do not use any rotting fruit, as the quality of
the juice produced depends on the quality and purity of the fruit used.
It is recommended to allow the juice to settle after pressing for three to four hours in another container to separate suspended solids from the juice.
Afterwards, fill your cask immediately with the fresh, pure juice.
Now apply 9 bar of carbon dioxide to the cask, in order to prevent any possible fermentation. Leave the gas bottle and fittings connected to the cask. If you do
remove the gas bottle (see "Exchanging the gas bottle") it should be noted that the pressure in the drink when saturated with CO² may drop (a natural reaction in
the formation of carbonic acid).
Initially, you will have an alcohol-free fruit juice. In the course of time, due to regular tapping of the juice, the alcohol content will increase slightly. This natural
process cannot be completely stopped without additives; however, the high pressure will inhibit this process to a large extent.
Note that the cleaner and fresher the fruit you use, the longer you will be able to draw your fruit juice alcohol-free.
Application 3: container for keeping fermented drinks fresh
The pressure cask is used with the addition of gas set, pressure reducer (CO²) and gas bottle (carbon dioxide) - see accessories. For using it with a gas connection,
please read the section "This is the right way to gas the cask".
This process is very widely used in the drinks industry. Carbon dioxide is used in the production of drinks. In addition, carbon dioxide is used by brewers and
wine producers nowadays because of its quality-enhancing effect. For example, in wine production the use of carbon dioxide impregnation makes it unnecessary
to apply too much sulphurisation.
Fill your SPEIDEL pressure cask with the fermented drink which you want to keep fresh (wine, fruit juice, beer).
Now pressurise the cask with 0.5-1 bar of carbon dioxide gas. This low pressure is adequate for drawing the drink and for keeping it fresh. Leave the gas bottle
and its fittings connected to the cask.
Application 4: sparkling mineral water / soda water
The pressure cask is used with the addition of gas set, pressure reducer (CO²) and gas bottle (carbon dioxide) - see accessories. For using it with a gas connection,
please read the section "This is the right way to gas the cask".
Take advantage of the quality of your drinking water. Drinking water regulations in Germany are some of the toughest in Europe and some of them are even
stricter than the mineral water regulations. This means that high quality drinking water is guaranteed. You can find out the quality and the characteristic values of
your mains water from your municipal administration (water supplies office).
Save yourself the costs of mineral water and the bother of carrying crates home. For a three-person household consuming reasonably large amounts of water,
the pressure cask and its fittings will pay for itself within about a year, according to actual usage.
Fill your cask with drinking water, leaving space for about three litres, to allow plenty of surface area to absorb the carbon dioxide and to speed the process of
saturation.
Thereafter, seal the cask and pressurise it with about 9 bar pressure of carbon dioxide. The water will saturate itself in a 50-litre cask in roughly 24 hours, to form
a pleasant, mild soda water.
After adequate saturation (maximum two days), you can close the carbon dioxide feed and remove the gas bottle as instructed (cf. "Exchanging the gas bottle").
The cooler the drinking water you use for making the soda water, the better and quicker the saturation.
If the CO² becomes saturated and converted to carbonic acid, the pressure will fall away to about 3-5 bar.

You require the following additional equipment: SPEIDEL Gas-set, pressure reducer (adjustable from 0 – max. 10 bar) and closable gas bottle with the
appropriate gas for the application (carbon dioxide), see accessories.
Unscrew the blind plug in the closure (0) of the tapping unit (A) (Allen key 7).
Screw in the coupling unit (1) at the bottom end (1a), with seal, into the position (0) of the tapping unit (A).
Screw the nut (3b) tightly to the pressure reducer outlet (4a), using the teflon tape to seal the thread of the pressure reducer outlet (4a).
Now push the pipe with the quick-coupler (2a) on the coupling unit (1b). Simply push in - ready.
The other end of the pipe (2b) is fitted to the pipe connection (3b) and tightened finger-tight with the union nut (3a) – already assebled.
Now make certain that all components are correctly connected. Each time before fitting the pressure reducer, set the tap at (4b) to "ZU" ("Closed") leaving
the adjusting screw (4c) for the working pressure screwed out completely, to ensure that pressure is not applied instantly.
Now connect the pressure reducer (4d) with the correct gas bottle.
Your system is now ready for action. According to application, you can now pressurise the cask with a maximum of 10 bar pressure (if this pressure is
exceeded, the safety valve will operate!!!)
This is carried out in the following manner:
open the gas bottle. At the manometer the bottle pressure will now be displayed. Now you can open the tap (4b) at the pressure reducer and adjust to the
pressure required with the adjusting screw (4c). The working pressure will be shown on the manometer and at the pressure reducer.
Exchanging the gas bottle:
When you want to change the bottle to apply some additional gas or simply want to remove it because you have enough pressure, then first close the gas bottle and
then the tap (4b) at the pressure reducer. Make certain first that the gas bottle and the pressure reducer outlet (4b) are both closed! Then remove the quickcoupler (2a) from the coupling unit (1b). Now you can remove the pipe, pressure reducer and gas bottle from the cask. The pressure in the cask is always safely
protected by a non-return valve (1).
Cleaning:
Always observe the maxim that absolute hygiene is the first commandment!
Provided the inside of the container and the tapping unit are extremely thoroughly cleaned before the cask is filled, a tasty drink will be your reward. It is most
important that the first cleaning is especially thorough. Hygiene is essential for success, and therefore SPEIDEL offers as an accessory a cleaning rod, with which you
can clean the inside of your cask perfectly without problem. Also we recommend the use of baking powder as a cleaning agent. Fill the cask completely with water,
then add 2 or 3 sachets of baking powder. Seal the cask with the tapping unit and let it stand for one or two days. Then rinse it thoroughly.
As the first cleaning, the cask should be washed out several times with hot water, and possibly allowed to stand with baking powder for one or two days. The tapping
unit can be cleaned again with the brush supplied. Subsequently, it is recommended that the cask is thoroughly cleaned immediately upon being emptied. Never let
drinks residues dry on inside. You can let the cask stand under partial pressure until it is to be refilled, and then clean it thoroughly before re-use.
Recommendations and instructions are based on the experience gained in numerous experiments. However, they do not represent any form of guarantee.
Please take note of the following advice!
When working with the drinks pressure cask, pressure reducer and gas bottles, the following must be borne in mind:
Caution - risk of suffocation! Operation of the pressure cask and its accessories may only be carried out in ventilated areas so that if there is an escape of
CO² gas (e.g. on operation of the safety valve) there is no risk of suffocation.
Since any of the elements (cask, pressure reducer, gas bottles) may be under pressure, the greatest care must be exercised.
When working with gases, work must be carried out with an adjustable pressure reducer which has a maximum working pressure of 10 bar. Pressure
reducers for CO² are obtainable from us.
The pressure cask has a maximum permitted working pressure of 10 bar!
It is sufficient to tighten the individual elements tightly. Do not overtighten!
Do not use a tool of any sort to tighten the tapping unit (A). The connection is designed to be adequate when hand-tightened.
Do not remove the tapping unit (A), blind plug from the closure (0) or coupling elements (1) while the cask is under pressure!
Do not place or lay gas bottles in the sun. Do not store or work with gas bottles in overheated rooms.
Keep children away from the gas fittings, pressure reducer and gas bottles.
Read the instructions for use for pressure casks and applications for pressure reducers with care.
CO² / carbonic acid is recommended by experts as the gas to be used for these applications. For this reason, SPEIDEL only offers accessory fittings for use with
carbon dioxide / carbonic acid. For applications 1-3 you can also use tapping gas (nitrogen and carbon dioxide). For this, however, you need a special pressure
reducer and a different gas bottle - speak to your gas supplier.
When you acquire a CO² gas bottle, you are responsible for it being tested every 10 years by the registration authority. Speak to your gas supplier.
The 2kg gas bottle is designed for applications in connection with the 50L pressure cask. You can rent a larger gas bottle from your gas supplier.
For refilling gas bottles, we recommend you go to your local gas supplier. Look in the Internet under www.gase-net.de. You can also obtain gas refills in drinks
markets or some pet shops. If you have no way of getting your gas bottle refilled, we can offer a way to have your gas bottle refilled using a collect voucher.
When you use CO² for pressurisation purposes it should be noted that the gas combines with the drink to form carbonic acid. If the gas supply is removed, the
pressure in the cask may sink as a natural consequence of the formation of carbonic acid in the drink.
When tapped, the drink is likely to froth up, so it is recommended to use a bulbous jug with a large opening.
As a general rule, do not fill your cask to the brim, but leave some centimetres free.
Tap with care!
Do not introduce oxygen to the cask.
Any coarse pieces of fruit should be filtered out after the pressing and before the cask is filled.
For processing your fruit, we recommend you our complete range "Domestic fruit juice preparation". Please ask for a brochure directly from SPEIDEL or through
the Internet under www.speidel-behaelter.de.
