Refrigerant charging function
Refrigerant charge amount can be set by the technician, or by selecting car make and model in the database.
Refrigerant can be charged through the high side, low side, or high and low side.
Note,
vehicle A/C system should be switched on when charging through the low side of the vehicle A/C system.
Note,
if charging is selected from
the
high and low sides simultaneously, care must be taken. After charging
function is completed and before starting the engine and switching on the A/C system, turn the compressor hub
several times by hand to expel any liquid refrigerant that may have accumulated in the compressor compression
chambers during the charging process.
Not performing this process can damage or destroy the compressor.
Hose purge
, hose purge is selected in charge function (default), to charge the full amount of refrigerant selected.
Some refrigerant will be left in the discharge hose (high side service hose) either at charge function or at A/C
diagnosis with vehicle A/C on. Follow the instruction displayed on the touch screen to purge the remainder of
refrigerant left in the discharge hose into the vehicle A/C system. This will make certain that 100% of the selected
amount of refrigerant is fully charged into the vehicle A/C system.
Tank fill
Please note, refrigerant identification is highly recommended before transferring refrigerant into
the machine's internal storage cylinder, by using a reliable refrigerant identifier.
Select
Tank fill
to fill or add refrigerant into a machine storage cylinder. It is recommended to maintain 4-6 kg
refrigerant in the machine internal cylinder at all times, to guarantee better charging and flushing operations.
During the refrigerant cylinder filling process, the machine will display to the technician to
close the hand valve
on the external cylinder,
and the machine will then recover the rest of refrigerant which is left in the transfer
service hose and internal pipelines.
The minimum tank fill set value is 0.5kg.
The maximum tank fill set value is the calculation result of 8kg (80% of tank allowable maximum weight) minus
the amount of refrigerant the tank contains (For example, if there is 2kg refrigerant in the equipment tank, the
maximum tank set value is 6kg).
