1. The pressure adjustment of CO2 pressure reducer is adjusted at 0.2 ~ 0.3MPa on the low pressure gauge under the premise of confirming the normal operation of CO2 pressure reducer, and finally the wine from the wine outlet of DISTRIBUTOR does not contain bubbles.
2. The barrel of draft beer machine is shaken or rolled, resulting in abnormal rise of pressure in the barrel, and the pressure in the barrel is moderately discharged. Minimize the direct application of wine barrels after transportation.
3. The cooling of draft beer machine is abnormal. If there is no ice plate or the ice plate is too thick, including power supply problems, compressor problems, cooling system problems, refrigerant leakage, etc., please ask professional technicians for maintenance
4. Water mixing motor failure includes water mixing motor damage, water mixing fan blade damage or falling off
5. When the water level of the water tank is low, add clean water to completely submerge the stainless steel coil.
6. The wine outlet rate is too fast. Adjust the wine outlet flow rate to make the draft beer pure and transparent without impact.
7. The method of receiving wine is wrong, so that the wall of the low-temperature clean wine cup tilts 45 ° close to the outlet of the wine head, and the opening and closing process of the wine head should be rapid and concise.
8. The wine road is not cleaned on time, and the professional draft beer machine cleaning agent is applied, which is cleaned every 7 days or so.
9. The draft beer barrel has just been replaced or will be emptied
10. If all kinds of adjustment methods are ineffective, please replace the new wine barrel test. "Pressure regulation of CO2 pressure reducer" and "abnormal refrigeration of draft beer machine" are the most important items in the above inspection.
Note: if you don't drink for a long time, it's normal to have large foam in the first to second glasses.
Solution to avoid foaming
In order to make each glass of wine, make sure the following items before making wine:
1. The draft beer machine has been continuously powered on for 1 hour, with excellent refrigeration effect, the water level in the water tank has fully submerged the copper pipe and stainless steel coil of the evaporator, the water stirring effect of the water stirring motor is excellent, and the application status of CO2 pressure reducer is excellent.
2. The rubber rings of distributor and wine spear are not damaged and there is no cross gas.
3. Draught beer barrels are not directly used after long-distance transportation or strong shaking.
4. The draft beer cup is clean and low temperature. The method of receiving wine is that the glass wall is close to the outlet of the wine head.
5. The flow rate of wine from the wine head is stable without rotating impact.
