Oil injection
When A/C system in deep vacuum state, select “Oil inj.” icon and press ENTER to start the process.
Oil enters A/C system through high side service hose.
You can choose “hose flush” to flush and discharge oil remaining in machine internal pipelines and
service hoses, to avoid cross contamination of different oils which may cause damage to A/C
system.
It is a MUST to select “hose flush” when you inject POE or any other oil to hybrid or
electric vehicles, with PAG oil may remain in machine or service hoses because of previous
operations.
You can determine oil injection volume by setting amount or by manual injection. Manual oil
injection is effected by pressing right arrow key on control panel. Please be aware that there is no
oil load cell equipped in the machine (the oil injection volume is calculated by injection time), thus
the oil volume injected may vary from the amount preset.
Charge
Select “charge” icon and press ENTER to start the process.
You can manually set charge amount with volume, or select “Charge by database” to set charge
amount by car make and model.
You can choose to charge through high side, low side or both sides.
After charge and A/C performance is checked with engine and A/C ON. “Hose purge” option helps
charge the refrigerant in service hoses into vehicle A/C system, to ensure better charge precision.
Tank fill
Select
Tank fill
to fill or add refrigerant into machine storage cylinder. It is recommended to
maintain 4-6 kg refrigerant in the machine internal cylinder at all time, to guarantee better charging
and flushing operations. During the refrigerant cylinder filling process the machine will display to
the technician to
close hand valve on the external cylinder,
the machine will then recover the rest
of refrigerant 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 amount of refrigerant the tank contains ( For example, if there is 2kg refrigerant in
the equipment tank, the maximum tank set value is 6kg).
