Here are some additional instructions on how to use the regulator cap:
The current cap design has a safety feature to relieve pressure from the uKeg through the top and sides of the cap if needed. It also relieves pressure in the uKeg if the selector dial is in the OFF position. To get the best performance out of your Regulator Cap, please follow these suggestions:
If beer happens to seep in through the relief mechanism, you may see it dripping from the sides of the cap. Don't worry, your cap is not broken. But if the beer dries in the regulator, you may find that it leaks CO2 constantly or won't pressurize the uKeg. You'll need to clean your cap, which is an easy and safe job that can be done in about 5 minutes.
