Please note that the above diagrams are for demonstration purposes only. You may have a different
style coupler or tap and shank setup to what is shown in the above diagrams.
The pressure to be set on your regulator differs according to the temperature that the keg is stored
at. If the product is stored at a higher temperature it will require a higher pressure to maintain the
desired level of carbonation. Refer to a carbonation chart to determine what pressure you should be
setting your regulator at to reach your desired level of carbonation.
For most styles of beer, you should be aiming for a carbonation level of between 2.3-2.8 volumes of
carbonation with the average carbonation level being 2.6 volumes (if you are unsure of the
carbonation level of the beer i.e. if it is a commercial keg then assume it is at 2.6 volumes of
carbonation). To achieve a specific carbonation level during carbonation or priming refer to the table
in the link below and correlate the temperature of the keg with the desired carbonation level.

NOTE: Do not try to fix a slow or fast pour rate by adjusting the dispensing pressure. This will result
in your beer either going flat or over carbonated. It is best to adjust the beverage line length and
diameter. If the pour is too fast and is producing a lot of froth then increase the length of the
beverage line between the G40 and the tap. Alternatively if the pour is too slow then decrease the
length of the beverage line between the G40 and the tap.
When adjusting your beverage line length to achieve the perfect pour it is always best to start with a
longer length of beverage line as you can always trim a longer length of hose.
Flooding a font
The G40 is supplied with an in-built agitator pump which also doubles as a pump which can be used
to flood a font. To flood a font attach silicone tubing to the 10mm “Water OUT” barb and then
attach this to the glycol inlet on your flooded font. Then attach silicone tubing to the outlet on your
flooded font and attach this to the 10mm “Water IN” barb on the G40.
For best results you should insulate the silicone tubing between the G40 and the flooded font.
Furthermore, if your flooded font is in a very hot environment then the font may not ice up as the
heat ingress into the font may prevent the condensation forming ice.
Using the G40 for fermentation control
Although the G40 can be used to control fermentation temperature it should primarily be used to
flood a font or dispense product, instead we would highly advise a G20 primarily be used for
fermentation control. If you were going to use the G40 for fermentation control then it is suggested
you adhere to the following advice and steps.
It is not advised to use the agitator pump to supply glycol to cool a fermenter, this is due to this
pump not being powerful enough to overcome the resistance of the cooling coils or large fermenter
jacket, and hence it is advised that an external pump be used connected to an external temperature
controller (
