Beer system troubleshooting 10 16-13

  1. 1. WELCOME Beer System Troubleshooting 101 2 Jack Busack Patrick Hahn Tom Zalewski
  2. 2. Objectives It‟s not rocket science – it‟s beer science! • To provide a basic knowledge of beer system issues • Identify problems and issues • Provide information on correcting issues • Interactive presentation – please bring your beer system troubleshooting scenarios so we can help! Beer System Troubleshooting 101
  3. 3. Where to come for help • Perlick Milwaukee technicians • Certified installer network • Test coupler kit Beer System Troubleshooting 101
  4. 4. Troubleshooting process To find the true cause of the problem in the shortest amount of time, follow this process on every call: • Ask the customer to describe the problem • Find out which faucets are affected, when the problem started, whether it reoccurs and if there is a pattern Beer System Troubleshooting 101
  5. 5. Troubleshooting process • Check the temperature of the beer in the cooler and at the faucet: 34 – 38 degrees is ideal • Temperatures above 40 degrees may cause foaming problems • Check the pressure, making sure that the applied gauge pressure is set properly for the system – call Perlick with the Power Pak serial number for design pressures Beer System Troubleshooting 101
  6. 6. Troubleshooting process • Check the sanitation procedures – make sure the system and glasses are being cleaned properly • Check the faucet to make sure it‟s clean • Check to ensure the Power Pak is operating properly and the digital readout is 30 – 34 degrees • Check the glycol solution flow to ensure the recirculating pump and motor are operating properly Beer System Troubleshooting 101
  7. 7. Troubleshooting process • Check the FOB detector operation – smart couplers or wall mount style: Are they vented and reset properly? • Check the operation of the Flojet beer pumps and flow reversal valves when applicable • Check the nitrogen and CO2 supply feeding the blender to make sure it‟s operating correctly Beer System Troubleshooting 101
  8. 8. Troubleshooting process • If the nitrogen or CO2 gas runs below the designed inlet pressure of 45 – 70 psi, the blender shuts off and goes into protection mode • Make sure the blended outlet pressure is set and the outlet shut-off valve is open. Beer System Troubleshooting 101
  9. 9. Draft beer systems are a balancing act Correct temperature Correct applied pressure to keg Beer needs to stay packed together, prevent breakout of the CO2 from the beer solution Beer System Troubleshooting 101
  10. 10. Problem: Wild beer Description: There is too much foam and not enough liquid beer. Causes: • Number one cause: warm beer • Beer drawn improperly • Creeping regulator • Applied pressure is set too high • Hot spots in beer line • Use of non-insulated beer line Beer System Troubleshooting 101
  11. 11. Problem: Wild beer Causes: • Tapped into a warm keg • Cooler malfunctioning • Kinks, dents, twists or other obstructions in the line, or restrictors • Faucets in bad, dirty or worn condition • Saturated insulation due to flooded chase • Power Pak is not functioning properly • Air shaft blower not functioning properly Beer System Troubleshooting 101
  12. 12. Problem: Unpalatable beer Description: Beer has an off-taste. Causes: • Expired beer! Beer is at its best before 30-45 days past its racking/ production date • Dirty or old beer lines • Dirty faucet • Unsanitary bar conditions, glass washing • Contaminated beer Beer System Troubleshooting 101
  13. 13. Problem: Cloudy beer Description: Beer appears hazy or cloudy in glass. Causes: • Frozen or nearly frozen beer • Old beer • Beer that has been unrefrigerated for long periods of time • Dirty glass or faucet Beer System Troubleshooting 101
  14. 14. Problem: False head Description: Large soap-like bubbles, head dissolves very quickly. Causes: • Applied pressure required does not correspond to beer temperature • Improper pour • Beer lines are warmer than beer in keg • Dirty glasses Beer System Troubleshooting 101 „False head‟
  15. 15. Problem: Flat beer Description: Foamy head disappears quickly. Beer lacks usual zestful brewery-fresh flavor. Causes: • Wrong blend of mixed gas is used • Dirty glass – not „beer clean‟ • Applied pressure is set too low • CO2 is turned off at night • Beer is too cold Beer System Troubleshooting 101
  16. 16. Troubleshooting Step 1 • Check and adjust regulators to the design pressure. • Don‟t try to estimate what the pressure should be – all glycol systems have a “designed” pressure that must be used. Beer System Troubleshooting 101
  17. 17. Troubleshooting Step 2 • What is the temperature of the coolant on the digital readout? • It should be 30 – 34 degrees. • Factory setting should be 30 degrees if not reset. This indicates the return temperature of the coolant. Beer System Troubleshooting 101
  18. 18. Troubleshooting Step 3 • What is the temperature of the walk-in cooler? • It should be between 35 – 40 degrees. Never depend on the dial thermometer on the cooler wall. • The most important temperature is that of the beer in the keg. • The best way to get this reading is with the Perlick test coupler kit. Beer System Troubleshooting 101
  19. 19. Troubleshooting Step 4 • Check for bubbles in the clear vinyl tubing inside the walk-in cooler leading from the keg coupler up to the wall bracket, FOB detector or beer pump. • Bubbles are a good visual indicator of improper temperature and/or incorrect applied pressure to the keg when being dispensed. Beer System Troubleshooting 101
  20. 20. Troubleshooting Step 5 Consider these questions: Is the beer breakup only occasional? YES Is the walk-in cooler used for items other than beer? NO Consider other answers. YES Cause of problem found. Solutions 1. Keep cooler door closed or use an air curtain 2. Set a colder cooler temperature 3. Use the cooler as a dedicated beer cooler Beer System Troubleshooting 101
  21. 21. Troubleshooting Step 6 Consider these questions: Is only Perlick tapping equipment in use? YES Consider other answers. Beer System Troubleshooting 101 NO Cause of problem found.
  22. 22. Troubleshooting Step 7 Consider these questions: Is the walk-in cooler too cold? NO Consider other answers. YES If the beer temperature is under 35 degrees in the walk-in cooler, the beer can overcarbonate if the applied pressure gauge is not set properly, especially if the beer volume used is moderate. Beer System Troubleshooting 101 YES Cause of problem found.
