OPERATIONS INSTRUCTION

Basic
operation
Testing
mode
● Upon startup, both modes (Testing Mode and Filling Mode) will
display their respective gear selections. When you select one
mode, the gear display for the other mode will disappear. For
example, if you select Testing Mode, the gear display for Filling
Mode will not be visible.
●
There are three pressure settings based on vacuum pressure
levels: -35KPa, -40KPa, and -45KPa.
● In Filling Mode, you can choose the appropriate gear for
vacuum pumping. After the vacuum pumping is complete, the
system will automatically proceed to coolant filling. If it doesn't
fill completely, you can perform multiple filling cycles.
● In the event that no coolant enters the system within two
minutes during Filling Mode, a fault reminder will be displayed.
●
In testing mode, if the selected vacuum level cannot be achieved
and maintained, the system will switch to pressure holding
mode within two minutes, a fault reminder will be displayed.
●
This equipment auto-calibrates at startup. Ensure system
hoses are at atmospheric pressure before powering on to
avoid zero calibration offsets.
●
Input air pressure range: 4.5 Bar to 8 Bar.
NOTE
Vehicle ignition is not required.
Begin by opening the drain valve before starting the operation.
(The vent valve is considered open when it aligns parallel to
the air hose.)
● Connect to a car battery or a 12V DC power supply and plug it
into the machine's rear power interface.
●
Toggle the switch to power on the machine. There will be a
buzzer sound to indicate that the machine is starting.
Connect the air inlet hose to the air compressor
●
●
Select the desired gear level, which is categorized by vacuum
pressure: -35KPa, -40KPa, or -45KPa.
