📘How to Use digital refrigerant gauge

First, attach the hose securely to the low-pressure pipe to ensure a tight fit.
Next, connect the vacuum machine to the right port and make sure it is sealed properly.
Then, carefully unscrew the low-pressure valve to release any pressure, using the right tools to avoid damage.
After that, turn on the vacuum pump and let it run until it reaches a complete vacuum.
Once the vacuum is reached, connect the service hose to the refrigerant canister, making sure it is tight.
Meanwhile, start the vehicle’s engine to power the air conditioning system during this process.
In addition, set the air conditioner to the maximum level to ensure proper refrigerant circulation.
Finally, check that the unit is in switchable mode for efficient operation and make adjustments as needed.
