The light on my SUB is not turning green.

Once in THE SUB, cooling down a SUB Keg takes 10 to 16 hours (depending on starting temperature of the Keg). When your beer is chilled to the right temperature, then the light on the front of THE SUB will turn green. To speed up the process, ensure your Keg is fully chilled before inserting it into the SUB. Set your fridge at the lowest temperature and store the Keg on the lowest shelf (this is the coldest area) for 6 to 10 hours, or until the cold indicator on the Keg turns dark blue.

The temperature of the Keg depends on the temperature in the fridge and the time the Keg has been in the appliance. If the temperature of the room is above 30 °C and the Keg has not been pre-chilled, it can happen that the light does not turn green. The temperature of the beer, in this case, is within 2 – 6 °C and still cooling. As long as the Keg has been in THE SUB for a couple of hours, it is not a problem that the light is still red.
