  If you're experiencing difficulty during the recovery and recharge phase with your BrainBee Air Conditioner, ensure that the refrigerant tank valve is open by unscrewing it counter-clockwise. Also, restore the normal seal conditions of the HP-LP taps gaskets and the HP-LP couplers, both internal and external. If yellow pipes are present, inspect and replace the seal gaskets inside the pipe connecting the solenoid valves group to the tank.

Why is refrigerant injection slow or not possible in my BrainBee multigas 8500 Air Conditioner?
- S
  Steven BurtonAug 21, 2025
  If refrigerant injection is slow or impossible in your BrainBee Air Conditioner, it may be due to cut joint seal gaskets from excessive tightening, causing pipe clogging and operational block. Locate and replace the defective rubber components or remove any dirt residue. Empty the gas, and if yellow pipes are present, inspect and replace the seal gaskets inside the pipe that connects the solenoid valves group to the tank.

What to do if the leak test has a negative result after the vacuum phase on my BrainBee Air Conditioner?
- S
  Stephanie OwenAug 23, 2025
  If the leak test result is negative after the vacuum phase on your BrainBee Air Conditioner, it might be because the vacuum time was too short (4-5 minutes). When a vacuum time less than 20 minutes is set, the following message appears: “Less than 20 minutes of vacuum do not guarantee the execution of a correct procedure. Continue?”

  If you notice a refrigerant leak from the exhausted oil container during the recovery phase, but the leak test is negative on your BrainBee Air Conditioner, it could be due to dirt inside the Oil discharge solenoid valve. Try cleaning the solenoid valve OUT – S, check the gasket efficiency, and calibrate the pressure sensor.

What to do if HP pressure gauge has the same pressure as the internal vessel gauge on BrainBee multigas 8500?
- C
  caitlynhortonSep 1, 2025
  If the HP pressure gauge shows the same pressure as the internal vessel gauge on your BrainBee Air Conditioner, it could be due to dirt inside the OUT “R” solenoid valve, failure of the OUT “R” solenoid valve, or manifold defects. Close the refrigerant internal vessel, then in Menu Service – Manual Activation open OUT “R” OUT “I” OUT “A” OUT “C” (compressor), close all valves once a pressure of 0 bar is reached. You can try to clean OUT “R”, substitute of OUT “R” or substitute the manifold.
