ANATOMY DIAGRAM & PARTS LIST

PRE-BREWING ASSEMBLY

Before use, we recommend cleaning your G40 and all of its components using the Grainfather High Performance Cleaner. For detailed cleaning instructions, see page 14.

1. INSTALLING THE FILTER
   Take the hop filter (4) and place it into the base inside the G40 body (6). It should be a tight fit and you’ll need to apply some pressure to make sure that it is securely in place.

2. ATTACHING THE CONTROLLER
   Remove the G40 controller (5) and the power cable from the packaging, and place the controller securely on the bracket on the front of the unit. Next, remove the small cap from the M16 socket (7). Plug the controller cable and M16 DC connector into the M16 socket and tighten the securing nut.

3. CONNECTING TO POWER
   Take the main power cable and plug it into the base the back of the G40. Next, plug the other end of the cable into a suitable power socket (15 amp in US/CA, 16 amp in 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 controller cable and the M16 DC connector 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. For instructions on how to enable 15 amp mode, please go to page 15.

THE G40 CONTROLLER

The G40 smart controller has built-in wireless connectivity, allowing you to use your mobile device as a remote control. Connect to the free Grainfather App for step-by-step brewing and access bazillions of recipes.

CONNECTION SETUP
When you first turn on the controller, you will be greeted with the connection setup screen. Press ‘set’ to go to the default screen.

DEFAULT SCREEN
The default screen shows the current temperature and target temperatures, unit symbol (Celsius or Fahrenheit), timer (when active), wireless connection status symbol and power mode (for those in AU/NZ).

MAIN MENU
This screen displays the main menu options:

NETWORK CONFIGURATION
On this screen, you can add a new wireless network and connect your G40 controller. To add a network, select ‘add new network‘, then follow the instructions on the next page. If you’ve previously connected your G40 to other networks, you can also clear these here.

SETTINGS
This screen displays the main settings:

• Power control mode: This mode allows for manual control of the power from the element in 5%increments. This can be used to control the power when distilling. Simply press ‘power control’ and use the up and down button to control the power.
  NOTE : This can also be controlled through the Grainfather App. Choose between manual or power mode on the main app screen and use the up and down buttons on the app.

• Change units: Choose between Celsius or Fahrenheit.

• Calibrate temperature: The G40 has two probes that are NTC (negative temperature coefficient) type temperature sensors. An NTC thermistor uses electrical resistance properties of ceramic or metal composites to measure temperature. These sensors are accurate to 0.050°C (0.025 °F). This feature allows for an offset to be applied to the reading of the temperature probe if it is inaccurate. This should only be used if the temperature probe is compared to a certified calibrated thermometer which has a resolution of +/-0.010°C (0.005°F).

• Boil temperature: Here you can adjust your boiling temperature based on the elevation of your brewing location. To use this function you can find the altitude of your location online, and also the boiling point of water at that altitude. Change the boil temperature from 100°C (212°F) to your new boil temperature.

• Buzzer settings: Within this section you can select silent mode for your controller. When enabled, you’ll no longer hear beeping to alert you when you’ve reached the next step during your brew.

• NZ/AU only: This is where you can change your unit from 10 amp to 15 amp mode if you choose to add more power. See page 15 for further details.

Within the Grainfather App you can now select recipes or even create your own. You can also use the step-by-step brewing system to brew confidently.

BREWING ON THE G40

You are now set up and ready to start brewing! Follow these instructions to guide you through your brew on the G40.

1. ADD THE MASH WATER
   Place your G40 on a flat, stable surface before you start brewing. We recommend positioning your G40 on the floor 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.
   NOTE: Ensure that the recirculation ball valve is open during this step to avoid a pump airlock.

2. SET THE MASH/STRIKE TEMPERATURE
   Using the G40 controller or your mobile device, set the required mash temperature and press the ‘heat’ button to begin 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
   Place the grain plate (14) inside the grain basket (15) and ensure that the plate is sitting firmly on the bottom of the basket.

4. INSTALL THE GRAIN BASKET
   Slowly insert the assembled grain basket into the G40. Ensure that the top of the grain basket rests flat on the support ring (2).

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.
   NOTE: The G40 does not require a top plate or an overflow pipe in the basket. The grain basket now has extra drainage holes, removing the need for these parts. You can choose to use a top plate when brewing higher ABV beers if 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 side of the basket. An additional grain plate can be purchased on the online Grainfather Store or at your local retailer.
   The maximum grain weight that the G40 basket
   can hold is 13kg. However, this is affected by grain crush, type and variety, and it may be easier to manage this by using an additional grain plate on top of the mash. If you’re unsure how well your particular grain bill will fit then we recommend mashing up to 12kg.

6. INSTALL THE RECIRCULATION HOSE
   Ensure that the hose is securely attached to the recirculation barb (13) and insert the barb into the recirculation opening on the side of the G40 body. Rest the other end of the hose on the top of the grain.

7. RECIRCULATE YOUR MASH (WORT)
   Ensure that the ball valve (11) on the top of the recirculation pipe (11) is open. Then, to begin recirculating, press the ‘pump’ button on the controller or via the Grainfather App. If recirculation doesn’t start, press the ‘pump’ button to turn it off, blow into the hose to clear the airlock, then restart the pump.
   TIP: To save time, we recommend preparing your sparge water during your mash.

8. LIFTING THE GRAIN BASKET
   When the mash has finished, turn off the pump and remove the recirculation hose. Close the ball valve on the recirculation pipe and insert the lifting bar (12) 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 (2).
   CAUTION 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.

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 millimetres above the grain and allow to drain.
   TIP: To save time, you can now start to increase the temperature in preparation for the boil.
   CAUTION BE VERY CAREFUL not to twist the basket while it’s in the sparge position as it could knock it the support ring. If the sparge is stuck and not draining, then remove the top grain 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 grain plate (if applicable) to continue sparging. Always ensure that the support ring fits tightly into its groove and is held in place by the support ring retainer (3). If you remove the support ring for cleaning, ensure that it is correctly reinstalled along with the support ring retainer.
   
   Once the sparge has finished, refit the lifting bar to the grain basket to lift and remove the basket from the boiler.
   NOTE : If you are using a large grain bill, we recommend scooping some of the grain from the basket to reduce the weight before lifting.

10. BOIL YOUR WORT
    After removing the grain basket, complete the boil and add the hop additions required by your recipe.
    CAUTION During the boil, do not fit the glass lid as you may cause a boil over.

COOLING WITH THE COUNTERFLOW CHILLER

The G40 includes a counterflow chiller (16). This has been designed to efficiently cool your wort, and allow easy, and sanitary transfer directly into a fermenter.

CLEANING
Before your first use, run cleaner through the counterflow chiller. For detailed instructions on how to clean your counterflow chiller, please refer to the CIP (Cleaning in Place) section on page 14. Also, ensure that your fermenter is clean and sanitised before cooling and transferring your wort.

FLOW RATES
The maximum flow rate of water through the counterflow chiller is 3L (0.8 US Gal) per minute. Do not exceed this flow rate as it may cause damage to the product. The maximum flow rate of wort through the counterflow chiller is 2.2L (0.6 US Gal). At this flow rate, with a tap water temperature of 20°C (68°F), the wort in the fermenter should be at approximately 25°C (77°F). You can get the wort in your fermenter close to 3°C (37°F) above your tap water temperature but reducing the flow of the wort through the counterflow chiller and adjusting the 1/2” ball valve (11).

1. At the end of the boil turn the heating element off. Create a whirlpool by stirring the wort vigorously with your paddle.
   NOTE: A moderate whirlpool may automatically form due to the force of the pump.

2. Place the counterflow chiller on a table or bench and push fit the hose barb on the end of connection A into the recirculation opening on the inside of the G40 body.
   NOTE: Ensure that none of your wort or water tubes are sitting underneath the counterflow chiller. The water tubes should be coming out from the top. If a tube is squashed or there is a kink, this will cause a pressure build up and liquid will not be able to pass through.

3. The coloured hoses are where the cold water enters and hot water exits. To allow cold water to enter, attach the blue hose to your tap, using your tap adapter set (18). The red hose is where the hot water drains out as it flows through the counterflow chiller. Connection B is where your wort exits the counterflow chiller.
   TIP: Collect some of the hot water from the red hose to use as cleaning water after your wort has finished transferring.

4.  To sanitise the counterflow chiller place connection D into the G40 body. Turn the pump on to recirculate hot wort back into the G40 to sanitise the inside of the coil. Complete this step without cold water circulating and recirculate for approximately 30 seconds to a minute,
   but no longer then turn the pump off.
   NOTE : The G40 is designed to cool while simultaneously transferring your wort to your fermenter. You should not cool by recirculating into your G40 as this reduces the thermal efficiency.

5. Ensure no hoses are kinked and that the water can flow freely then gradually turn on your cooling water and adjust the flow rate. Allow the cooling water to flow for two minutes then turn on the pump. Once connection D runs cool, switch the pump off and place the end of the hose inside your clean and sanitised fermenter and switch the pump back on. Always try to keep the fermenter opening covered to avoid contamination while transferring your wort.
   WARNING: The counterflow chiller is not intended for continuous hot wort circulation without cooling water flowing through. Do not use during processes like whirlpooling and hop stands.
   NOTE: Take an OG (original gravity) reading of your cooled wort before adding yeast as per the correct yeast pitching temperature within your recipe. Fit a bung and airlock to the top of your fermenter to keep it safe from contaminants that may spoil your brew.

ADVICE FOR CLEANING & STORAGE

No one really enjoys cleaning, but it’s worth it for great beer!

• After use, the G40 and all of its components should be cleaned immediately and dried thoroughly. We recommend using the Grainfather High Performance Cleaner as it removes the need for tedious scrubbing. However, all stainless steel components can be cleaned using a conventional, unscented brewing detergent/cleaner.
• Abrasive agents and sponges/brushes could cause scratching and are not suitable for use. Ideally, use a dish brush or soft sponge to clean the unit.
• Do not store in a damp area as this could cause damage to the product.
• Once you have cleaned your equipment, dry, reassemble and store.

CLEANING IN PLACE (CIP)

1. Remove all trub and solids from the G40 by removing the hop filter from the G40, rinse thoroughly and then put aside. Remove the hex nut (17) from the T-section of the recirculation pipework and flush the rest of the trub and other remains from the G40. You can now re-attach the hex nut.
2. Fill the unit with 15L (3.9 US Gal) of water and 1 cap of Grainfather High Performance Cleaner.
3. Heat the water to 60°C (140°F) and use a dish brush or soft sponge to clean the unit.
4. Attach the counterflow chiller and place the connection D hose from the chiller into a 5L (1.3 US Gal) jug. Once ready, switch the pump on and let the water run into the jug until the water clears. Now, place the hose into the unit so the water continues to recirculate and leave for 10−15 minutes.
5. Once complete, switch the heating and pump off, and remove the hex nut to allow the unit to drain.
6.  Once draining has finished, follow steps 2−5 again but this time with clean water to rinse and flush the G40 and counterflow chiller.

CAUTION: RISK OF BURNS
Use heat resistant brewing gloves or other suitable gloves during this process.

NOTE: You can choose to add an additional ball valve tap to make the cleaning process even easier. Please see the next page for more information.

PUMP CLEANING
We recommend cleaning your pump every 5−10 brew sessions. This process should be done after you’ve cleaned your G40.

1. Turn the unit upside down and remove the four screws on the base of your G40.

2. Using pliers, squeeze and shift the hose clamps away from the pump inlet and outlet.

3. Remove the four screws that hold the pump in place and detach the inlet, and outlet hoses from the pump.

4. Remove the screws holding the impeller housing to the pump.

5.  Remove the top cover of the impeller housing exposing the impeller.
   NOTE: There is no need to expose the magnetic drive pump.

6. Use a pipe brush or something similar to clean the impeller and impeller housing.
   NOTE: Do not submerge the pump in water.

7. Dry the components and reassemble the unit.

UPGRADE YOUR G40

Get the most out of your G40 Brewing System with these optional upgrades.

ADDING A BALL VALVE TAP TO YOUR UNIT
