7.
Check that each pump is operating correctly
This can be determined by looking for water flow through the silicone tubes or by
placing the outlet hose into a jug and ensuring that liquid is being pumped out of the
hose into the jug.

Set the temperature on the controller on the rear of the G20 above the IEC plug to 2°C.
Hold the ‘S’ button until F1 is displayed.
Press ‘S’ again which will enter temperature adjustment mode.
Then hold ‘S’ and up or down buttons simultaneously to alter the set temperature of the
reservoir.
During this step you can get a rough guide of the cooling factor of the glycol chiller when not under
load. To determine this note the starting temperature of the water in the reservoir and then
measure how long it takes to drop the temperature to 2°C.
Prior to putting any beer into the fermenter for cooling you should leak test your whole system. This
can be done by connecting the silicone tubing from the OUT barb to the cooling coil of the fermenter
and then connect the silicone tube from the fermenter to the IN barb on the G20.
Set the temperature on the temperature controller to 2C and test that there are no leaks in the
system including into the fermenter itself.
After all testing is complete empty the reservoir by removing the plug on the bottom 3/8” duotight
fitting on the nylon sight tube. This can be achieved by removing the blue retaining clip on the
duotight fitting and pushing in on the collar as you pull on the plug. After you have drained the
reservoir put the plug retaining clip back in place.
The system has now been tested for cooling and leaks and is ready to be used to cool a fermenter.
Filling the reservoir
The G20 can be operated with either just water in the reservoir or both water and glycol to reduce
the freezing point of water.
IMPORTANT: If you are only using water in the reservoir and not glycol then do not set the
temperature of the reservoir below 2°C.
Fill the reservoir to a total of 17L with water if the reservoir is set at 2°C or an appropriate
concentration of glycol solution if dropping the reservoir below 2°C according to the table below.
Ensure the cooling coils are submerged. The amount of glycol required to be added to the reservoir
depends on the desired set temperature of the reservoir which is dependent on a number of factors
including how many fermenters are being cooled, the ambient temperature the fermenters are in
and heat ingress etc. Use the table below to determine what percentage of glycol you require.
