INTRoDUCTIoN
Your personal brewery can deliver 23 Litres (6 US Gallons) of
cold, clear, perfectly carbonated, commercial quality alcoholic
beverages in 7 days, just like a modern brewery. It requires only
about 1 hour of your time. The quality of the products produced
was well and truly proven when a brewer on his 3rd brew in his
WilliamsWarn, beat 45 of the world’s biggest and brightest
breweries to win a Gold Medal for his Pilsner at the Asia Beer
Awards in 2012.

We suggest you read this User Manual from cover to cover before
you start to make your rst brew, so that you are familiar with the
process and timings involved. The Appendices are very important
toreadbeforeyoubrew,becausetheyexplaintheprinciples
behind the Standard Method that you will use in Part Two.
Never has making a commercial quality beverage at home or
the workplace been so easy. We promise that after using your
Personal Brewery you will be as passionate about making beer,
cider and other beverages as we are.
Thank you very much for your purchase and we sincerely hope
you will love your WilliamsWarn from the very rst brew.
Cheers.
We are very proud to bring you the Generation 2 WilliamsWarn® Personal Brewery.
The development of the rst model that we launched with in April of 2011 took over 6
years of effort and determination. In the following 12 months after launch, we sold out
of the rst batch of 70 that we had produced. We learnt much from this rst model
and we had a rapidly growing international demand, so we decided to seek investment
to improve the brewery and meet this response.
We received the investment we required in mid-2012 and then proceeded to develop
the Gen2 WilliamsWarn, a new set of ingredients and this new User Manual.

7.0 OTHER INFORMATION
These instructions for use outline general safety
guidelines for the correct operation of the WilliamsWarn
Personal Brewery System
Place the WilliamsWarn Personal Brewery upright on a
at, even and stable surface. Make sure it doesn’t block
a passage.
Take care when moving the brewery. The wheels on the
base allow the user to move the brewery on a at surface
in a straight line. Take care when moving the machine in
another direction.
The refrigeration system will emit warm air from the
ventilation ducts on the Brewery Tower. Ensure adequate
air ow for the ventilation system so that air is not
blocked or looped back.
Clear all spills from the surrounding oor in order to
maintain hygiene. Clean the drip tray regularly.
The brewery tower panels may be removed for maintenance.
Ensure only an approved service agent has access to the
internal parts in the brewery tower.
Do not try to open the tank lid or valve (or take sediment
bottle off without closing the tank valve) while under
pressure. Always relieve pressure before opening the
tank. Check the variable pressure relief valve (VPRV)
regularly to ensure that it is not blocked.

THE INGREDIENTS AND THEIR STORAGE
You will receive a set of ingredients and this user manual in
a separate delivery to the brewery. You must use this set of
ingredientsforyourrstbrew.AnexampleisshowninFigure5
(Part 2 of this manual).
LiquidMaltExtract(LME)agesovertimeandthiscanaffect
the beer avour. We keep all our LME cold until shipment to
you and ask that you continue this refrigerated storage policy
until the evening before use. So any LME you have needs to be
refrigerated until the evening before brewing, after which time
it should be put on a bench overnight, so that it can warm up to
roomtemperaturebeforeopeningthenextday.Thiswillmakeit
easier to pour. You can also warm the can up in hot water for 10
minutes prior to use if you forget to take it out of the fridge.
DryMaltExtract(DME)doesnotneedrefrigerationsocanbe
kept at room temperature indenitely. Keep it preferably in a
cool and dry area.
The clarication agent should not be kept below 5°C (41°F).
UNPACK THE BREWERY
Remove the protective cardboard packaging when you receive
your brewery.
Unscrew the four screws that attach the brewery to the pallet
and remove the brackets from their internal slots.
IMPORTANT: Keep the protective packaging, the pallet, the
screws and brackets in a safe place for possible future use if the
brewery needs to be shipped to a service agent for maintenance.
REMOVE THE EQUIPMENT STORED IN THE VESSEL
As well as your Personal Brewery, you have received some
equipment which has been placed inside the vessel during
transportation. This includes:
A. The Sundry Equipment to help you brew as shown in
Figure 6 (Part 2 of this Manual)
B. The Sediment Bottle and its neoprene cover
C. The Draft Tap Font as shown in Figure 3A
D. 2xU-shapedstainlesssteelwheelchocksasseenin
Figure 4A.
E. An electrical cord to connect to your brewery and your
electrical power source.
F. The drip tray.
Undo the vessel lid and unpack all these items.
POSITION THE BREWERY
Position your Personal Brewery in a place where it can remain
for the duration of the brewing process and beer dispensing
period. IMPORTANT: this will need to be on a at level surface.
The brewery is on four wheels which will enable you to push the
brewery unit in a straight line. They are not castors so in order
to change direction you will need to lift or drag the front or back
around to suit the direction that you require.
Toxthebreweryintoposition,pleaseslidethewheelchocks
around the two front wheels, see Figure 4A.
This will prevent the brewery from being pushed around.
It is preferable to keep the unit away from direct sunlight.
For electrical safety reasons the unit must be kept out of the
rain or wet area’s so is not suitable for positioning outside in an
uncovered area.
It is preferable that the unit is maintained in an ambient
environment between 5°C and 40°C (41°F to 104°F) and less
than 90% humidity.
Remove the white protective wrap from the stainless steel by
pulling it off with your hands. It should peel off easily and reveal
clean stainless steel.
Position the unit so that there is adequate air-ow through the
air ducts at the base of the brewery tower. This is to enable the
refrigeration system to work properly. It is important that the
ducts are not blocked in some way or that the air ow does not
loop back on itself. The area around the ducts may become
warm at times.
ACCESS TO MACHINE INTERNAL PARTS AND SERVICING
IMPORTANT: READ THIS SECTION CAREFULLY
We have carefully designed and constructed this machine so
that if necessary the user can access the internal parts of the
brewery if required. On initial set up of the brewery you will be
required to access this area.
Before accessing the rear protective panel you must ensure that
the brewery is not connected to the mains power supply.
In the future, should you need to access this area after the
gas cylinder is connected, you should also ensure that the CO2
cylinder is turned off at the cylinder and the pressure in the
tubing on the low pressure side has been released.
For the regulators supplied by WilliamsWarn to release pressure
on the low pressure side, wind the regulator knob out anti-
clockiwse to its closed position and the low pressure gas will
release itself.
