Jeff Flowers on July 16, 2014 22 Comments This regulator adjustment guide will help you with those final steps in assuring that your kegerator provides you with the highest quality tasting beer by walking you step by step through the regulator adjustment process. Step-by-Step Guide: Before you start, please make sure that your CO2 regulator is firmly and properly attached to the CO2 cylinder. This guide will primarily focus on using a single gauge regulator that is included with most kegerators; however, any regulator that can be used on a CO2 cylinder with a CGA-320 valve will work. 1. Open Gas Cylinder Make sure that the brass shut-off valve on the regulator (1) is closed (as shown above), then open the valve (2) on the gas cylinder completely. 2. Fine-Tune Adjustment Nut & Screw Loosen the regulator adjustment nut (3) by slowly turning the nut counter-clockwise until the screw becomes loose. Now, with a flat head screwdriver, turn the adjustment screw (4) clockwise until the desired pressure is shown on the output pressure gauge. We recommend setting the regulator at 12 PSI. NOTE: On regulators designed for draft beer, turning clockwise will increase the output pressure, and turning counter-clockwise will decrease the output pressure. Under normal circumstances we recommend setting the regulator at 12 PSI. Other conditions, such as altitude or special beer styles, may require some adjustment. Consult your keg distributor or the brewery of each beer for recommended PSI settings. 3. Allow Gas to Flow to Coupler Make sure the keg coupler is locked in the downward position. Open the shut-off valve (1) on the regulator to allow CO2 gas to flow from the regulator to the keg coupler. NOTE: You will hear the keg pressurizing. The output needle on the regulator should drop momentarily until the pressure has equalized, then the needle will return to the previously set pressure. 4. Briefly Vent Gas on the Pressure Release Valve The keg coupler is designed with a pressure release valve. Pull the ring on the pressure release valve briefly to allow gas to vent. You will hear a sharp hissing noise once you pull the pressure release valve. NOTE: This is important to do, as it will help gas flow through the regulator and help obtain a more accurate reading on the output pressure gauge. 5. Double Check the Output Pressure Next, you will want to re-check the output pressure on the regulator, and if necessary re-adjust using step #2 until the desired pressure is shown. NOTE: It is always wise to follow up any adjustment to the regulator with a brief pull of the pressure release valve ring to help ensure an accurate pressure reading. 6. Make Sure Beer Pours Properly Check to make sure that beer pours properly out of the faucet. The beer should dispense at a normal pace. If beer is wild, cloudy, or off-tasting, check the owner’s manual for tips on how to remedy common dispensing issues. NOTE: To check for CO2 leaks, drip some soapy water on the CO2 cylinder and regulator connection. If soapy bubbles form, you may need to tighten or re-attach the gold regulator nut connection to the CO2 cylinder.
