7.5 Purge
The purge is designed to discharge the mixed non-condensable gases in the
inner tank. It is harmful for the A/C station when the tank pressure is exceeded. It must
release some pressure till to normal level. You no need to do this operation every time
when you service a car, but need to check the tank pressure through the gauge in the
morning before using it. Or the tank pressure is too high in some cases, you must stop
all other to purge operation.
1. In stand by mode, press
key to purge mode
Note: The highlight "H" on the l ow er right corner is the prompt that you can long press
key to get help information about the current operate.
2. Press
key, the display will show the ambient temperature and the calculated
relative pressure of refrigerant in theory.
3. Check the tank pressure. If the gauge pointed pressure is no higher than
displayed value, it means that no mixed gases in the tank, you can stop the
operation and select the other ones. If the gauge pointed pressure is higher
than displayed value, long-press
key, the device will start to
release the gases, till the pointed pressure come near to the relative valve on
