Inaccurate flow meter

  • Check Flow meter (Solution: Extract beer by using flow meter and place flow meter lever on the right place )

CO2 regulator is out of order 

  • Check the location of gauge indicator and amplitude of vibration. (Solution: Request for A/S)

Gas leaking from the head

  • Check Rubber packing on the head. (Solution: Exchange the head make %2 CInquiry to A/S)

Coke is worn. Or loose assembling

  • Check condition of rubber packing. (Solution:Exchange shaft and ask for A/S. Remove Coke and clean with Warm water.)

poor at extract draft beer

  • Learn and become familiar with extract skills. (Solution:Bring the glass near coke.
    And hold the glass askew (45 degree) )


Causes and Solutions.

Low pressure of CO2 gas.

  • Check CO2 regulator. (Solution:Set to proper pressure. (Raise 5~10 in Summer season)
    - Large Cooler :40~55 PSI
    - Regular Cooler : 30~40 PSI
    - Small Cooler : 30~35 PSI)

Inaccurate flow meter

  • Check flow meter. (Solution: Extract beer by using flow meter and place flow meter lever on the right place.)
