Flushing function (COR, Compressor Oil Recovery, Optional)

For HFO-1234yf system, refrigerant identification is necessarily processed. Only when the purity of refrigerant

is above 98% the recovery is allowed.

Please note, empty used oil vessel before starting this operation.

Flushing function is performed to completely extract compressor oil from A/C system, thus contaminants such as

acidified substances, moisture and other foreign particles will also be extracted together with oil.

During the flush, refrigerant flows in the forward direction (charge liquid refrigerant from A/C low side to

dissolve compressor oil, and at the same time recover from the high side) and reverse direction (reverse direction

means charge from the high side and recover from the low side, in reverse from normal A/C flow), each direction

lasts certain period of time. Flush time can be set corresponding to refrigerant amount in system. For example,

A/C system with 500g refrigerant, flush time is recommended to be set at 30 minutes, while 60 minutes can be

set for system with 1kg or more refrigerant. Flushing refrigerant will be recovered and purified automatically, at

the end of the flushing process and stored in the storage cylinder, ready for re-use.

For some A/C system equipped with evaporator solenoids or electronic expansion valves, which are normally

closed when the vehicle A/C is off, it is recommended to activate the solenoid and TX valves with proper

diagnostic scanner or remove and bridge these valves with the appropriate bridging fittings. Not performing the

above, refrigerant flow is restricted and flushing efficiency can be affected.

For a multi-flow condenser, the oil in the condenser may not be flushed out completely.

Note: Each flush will cause about 200g refrigerant loss.

Remarks: As one of the innovative technologies created by BLUDEE, COR offers a new method of automotive

A/C maintenance and may highly reduce A/C repetitive repair rate. Please consult BLUDEE professionals to

get more technical tips for flushing.

Automatic function mode

Please note, empty used oil vessel before starting this operation.

In automatic function mode, the machine runs flush, recovery, evacuation, vacuum test if selected, oil injection,

dye injection and refrigerant charge in sequence, with data of each operation preset by the technician.
