Once in THE SUB, cooling down a TORP takes 10 to 16 hours (depending on starting temperature of the TORP). 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 TORP is fully chilled before inserting it into the SUB. Set your fridge at the lowest temperature and store the TORP on the lowest shelf (this is the coldest area) for 6 to 10 hours, or until the cold indicator on the TORP turns dark blue.
The temperature of the TORP depends on the temperature in the fridge and the time the TORP has been in the appliance. If the temperature of the room is above 30 °C and the TORP 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 TORP has been in THE SUB for a couple of hours, it is not a problem that the light is still red.
