PRE-BREWING ASSEMBLY CONNECTING TO POWER & THE CONTROLLER
1. INSTALLING THE FILTER
Takethehoplter(4)andplaceitontheinsidebase
oftheG40body.Itshouldbeatighttandyou’llneed
to apply some pressure to make sure that it is securely
in place.
2. ATTACHING THE G40 CONTROLLER
Take the G40 controller (5) and the 2m power cord
from its packaging and place the controller securely
on the bracket on the front of the unit. Next remove
thesmallcapfromtheM12socketthat’slocatedatthe
front lower section of the G40. Plug the M12 cable into
the socket, making sure that the right angle connector
is facing upwards. Finally, tighten the securing nut.
3. CONNECTING TO POWER
Take the main power cable and plug it into the base
at the back of the G40. Next, plug the other end of the
cable into a suitable power socket (15 amp in USA,
Canada&EU,13ampinUKor10ampinAU/NZ).The
display screen on the controller should now turn on,
however
if this does not happen, please check that
both the M12
controller cable and connection are
securely attached and check the main power cable.
NOTE (NZ/AU ONLY):
The G40 has a default 10 amp mode, but it can also be
used in 15 amp mode if you wish to add more power
to your system. To enable 15 amp mode, your power
socketmustbeprofessionallyinstalledbyacertied
electrician or you will void your warranty. The 15
amp cable is sold separately on the Grainfather store.
To change your system to 15 amp mode, please go to
“Settings” on your G40 controller and then press and
hold the “Heat” button for 10 seconds. This will prompt
youwithawarningmessagewhichwillconrmthat
you would like to switch to 15 amp.

Before use, we recommend cleaning your G40 and all of
its components using the Grainfather High Performance
Cleaner. For further information on cleaning, please refer to
the full instructions online: grainfather.com/instructions

4. INSTALL GRAIN BASKET
Slowly insert the assembled grain basket (14)
into the G40.
5. ADD GRAINS AND STIR
Once your water reaches the set temperature, slowly
add the grain to the grain basket, stirring well to avoid
any dry clumps.
6. INSTALL THE RECIRCULATION HOSE
Ensure that the hose is securely attached to the
recirculation barb and insert the barb into the G40 body.
Rest the other end of the hose on the top of the grain.

BREWING ON THE G40
NOTE: Unlike existing Grainfather Brewing Systems,
theG40doesnotrequireatopplateoranoverow
pipe in the basket. The newly designed grain basket
with extra drainage holes has removed the need for
these parts. You can use a top plate when brewing
higher ABV beers where you will be maximising
the amount of grain used in the G40. In this case,
the top plate can help to keep grain in the basket if
the wort levels are too high and stops any wort from
draining through the lifting bar holes on the side of
the basket. The top plate can be purchased on the
Grainfather shop.

4. ADVANCED WIRELESS CONNECTION AND APP CONTROL
At this point you will be able to use your new G40 and
complete a brew using the G40 controller. The G40 is
designed with smart features, wireless connectivity,
and is compatible with the free Grainfather App,
whereyoucanndrecipesandrunyourbrew
session remotely from your mobile device. For more
information on this please read the full instructions
online:grainfather.com/instructions
1. ADD THE MASH WATER
MakesurethatyourG40isonastable,atsurface
before you start brewing. We recommend placing
yourG40ontheoorduetoheavyliftingthatis
required later in the brewing process. Add the
volume of mash water required by your recipe –
you can use the advanced calculators available on
the Grainfather App.
2. SET THE MASH/STRIKE TEMPERATURE
Using the G40 controller, set the required mash
temperatureandpressthe‘Heat’buttontoinitiate
heating. Place the lid on the G40 to reduce the heating
time. At this stage, if your G40 is connected to the
Grainfather App, you can run your brew session
remotely from your mobile device.
3. ASSEMBLE THE GRAIN BASKET
Insert the bottom plate into the grain basket and
makesurethatitissittingatatthebottomofthe
basketandthatittstightly.
NOTE: This section of the quick start guide
outlines the key steps during the brewing process.
For further information, please refer to the full
instructionsonline:grainfather.com/instructions

7. RECIRCULATE YOUR MASH (WORT)
First, open the ball valve on the top of the
recirculation arm on the side of the unit. Then, to
beginrecirculating,pressthe‘Pump’buttononthe
controller or via the Grainfather App.
NOTE: To save time, we recommend preparing your
sparge water during your mash.
8. LIFTING THE GRAIN BASKET
Whenthemashhasnished,turnothepumpand
remove the recirculation hose. Close the ball valve
on the recirculation arm and insert the lifting bar
into the holes inside the grain basket. Lift the grain
basket and then turn it 45° so that the feet at the
bottom rest on the basket support ring.
9. SPARGING AND BASKET REMOVAL
Allow the mash liquid to drain into the boiler. Then,
gently pour the sparge water evenly over the grain
until the water is a few mm above the grain and allow
to drain. (Tip: To save time, you can now start to
increase the temperature in preparation for the boil).
Oncethespargehasnished,rettheliftingbarto
the grain basket to lift and remove the entire grain
basket from the boiler.
NOTE: If you are using a large grain bill, we also
recommend gently scooping some of the grain from
the basket to reduce the weight.
10. BOIL YOUR WORT
After removing the grain basket, complete the boil
without the lid and add the hop additions required by
your recipe.
7
CAUTION!
CAUTION!
Duringtheboil,donotttheglasslidasyoumay
cause a boil over.
A TWO PERSON or mechanical lift
is recommended when using larger
grain bills on this system. A single
person lift may lead to serious injury.
BE VERY CAREFUL not to twist the basket while
the basket is in the sparge position which could
knockitothesupportring.Ifthespargeis“stuck”
(not draining), then remove the top plate (if
applicable), lower the basket and slice the grain
bed with a stainless steel paddle or similar. Cut
through the stuck grain from the centre towards
the outside repeatedly until it loosens. Then return
the basket to the sparge position and replace the
top plate (if applicable) to continue sparging.
AlwaysensuretheSupportRingtstightlyinto
its groove and is held in place by the Support
Ring Retainer. If you remove the Support Ring
for cleaning, ensure that it is correctly reinstalled
along with the Support Ring Retainer.

IMPORTANT SAFEGUARDS:
READ AND FOLLOW ALL INSTRUCTIONS
CAUTION –
Riskofresandelectricshock.
– Replace only with genuine Grainfather cord set, part No. SJTO.
– Do not immerse in water.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
FOR COMMERCIAL AND INDOOR USE ONLY
11. COOLING WITH THE COUNTER FLOW WORT CHILLER
TheG40includesacounterowwortchiller(15)
designedtoecientlycoolyourwort,andalloweasy,
and sanitary transfer directly into a fermenter. At
the end of the boil, circulate hot wort through the
counterowwortchillerfor2minutestosanitise
it. Then, turn on your cooling water and transfer
yourwortthroughthecounterowwortchillerinto
your cleaned and sanitised fermenter. For detailed
instructions on how to use this equipment, please
readthefullinstructionsonline:grainfather.com/
