1.) Use shutoff valve to turn off gas to coupler.

2.) Disconnect coupler from keg; disconnect gas line from coupler.

6.) Reconnect coupler to the keg. Turn the gas supply back on.

3.) Ensure DraftMore check valve (B) is in place. We recommend using the DraftMore check valve in place of the check valve provided with your coupler.

DraftMore should be beer temperature. Seal DraftMore in plastic bag, dunk in ice water for 10 minutes to cool. Do not get DraftMore wet; dry if needed. Wear gloves during install to avoid warming DraftMore.

Know the gas source and beer type, and be sure that you have the correct DraftMore unit.

Ensure system is set up correctly. Prepare to deal with beer flow issues if system pressure changes by 1.5 psi

8.) Bleed the system by opening the safety on the coupler. Listen for the sound of gas flowing back into the keg.

DraftMore will not fix a keg that is foaming. Best results are with a new keg.

9.) Spray soapy water on all connections and look for bubbles (leaks).Add 1 psi to gauge PSI for every 2000 feet above sea level. Beer gas charts can be found at www.mcdantim.mobi. Use Easy Pressure.

If keg with DraftMore is removed from cooler, put a bag of ice on DraftMore.

5.) Install DraftMore tightly on coupler. Snug (do not overtighten) hex bolt. Twist gas line counterclockwise 5-6 times before installing to prevent kinks; attach hose end to DraftMore.

10.) Pour 1 -2 beers through the system to clear the lines and check that beer flow is good. This also helps DraftMore set to the correct pressure.

7.) Set system pressure where DraftMore is attached to 2 - 3 psi or more above equilibrium (use chart - right). Use our ADD A GAS LINE KIT if needed so that other beers in system are not adversely affected.

4.) Ensure a washer (A) is between DraftMore and gas hose.

Installation Checklist

Are hoses, coupler, tap and keg seals in good shape? Damaged seals or worn parts can cause foaming.

Is the gas turned on, and is the pressure correct for the system? Check the chart above.

Is there gas in the cylinder(s)?

Is the FOB reset / present? The FOB should be full. If there is no FOB in a long draw system, substantial foaming between kegs will occur.

Is it a fresh keg? DraftMore cannot help when a keg already has problems. Best results are with a new keg.

Is DraftMore the same temperature as the beer? 2 - 3 beers through the system will help cool it off.

Is the beer cold at the tap? If glycol system is faulty or set wrong, beer can warm in the line, causing foaming. At the tap beer should be as cold or colder than the keg.

Is the system pressure set higher than the equilibrium pressure? The system pressure must be at least 2-3 psi above equilibrium pressure to ensure DM can work properly. This may require the system to be adjusted for proper beer flow. If needed, use our ADD A GAS LINE KIT to avoid upsetting system balance.

Is the flow rate correct? Beer should flow between 1.5 - 2 oz per second. Any faster will cause CO2 breakout in the glass. Add restriction or use a flow control to slow down beer flow if necessary. If adding restriction, do so after the FOB (when present).

Is the temperature correct? Draft beer should generally be stored between 36 - 38 F. Colder systems result in less head and more dissolved CO2. For warmer beer, rinse glasses with warm water before pouring.

Is the glassware clean and cold? Unclean glassware, residual sanitizer and frozen or hot glassware can all cause foaming. A cold water rinse prior to pouring is best. Ensure staff are trained to pour properly.

Does the beer pour clear, then foamy? There is a hot spot in the line, or the applied pressure is not high enough. Check the line for bubbles, evidence of low pressure. In a mixed gas system you may not see low pressure in the lines due to higher hydraulic pressure. Check the beer gas charts at McDantim.com to ensure pressure is correct.

General System Checks

Beer Side Checks Gas Side Checks

Does the beer pour foamy, then clear? Likely cause is beer in the line or at the tap warming, causing breakout. If system is air cooled, check airflow. For a glycol system, ensure line is cooled to shank and insulation is in place. Other causes could be a pressure drop from too much restriction, or a small leak in the system.

Have the lines been cleaned regularly? Unclean lines can cause foaming problems and affect the beer taste.
