Preparations before operation
1. Unlock tank load cell
Unlock the load cell by removing the safety locking bolt as shown below and save the bolt for future use.
PLEASE NOTE, whenever transporting the machine, re-fit the safety locking bolt to avoid damage to the load
cell.
2. Tank fill
Use the adaptor fitting, to connect either HP or LP service hose (red or blue) to the external refrigerant cylinder
liquid port which you will be transferring the refrigerant from. If the refrigerant cylinder has only,
One valve and one port, invert the cylinder as shown below. If the cylinder has,
Two valves one port, leave the cylinder upright and open the liquid valve only, if the cylinder has,
Two valves and two ports, connect the adaptor to the liquid port, leave the cylinder upright and open the liquid
valve on the cylinder. Set the amount of refrigerant to be transferred into the machine storage cylinder, once the
selected amount of refrigerant has been transferred, the machine will instruct the technician to close the liquid
valve on the external cylinder. The machine will then recover the remaining refrigerant in the service hose which
is connected to the transfer cylinder and it will then stop automatically. For more details, please refer to “tank fill”
in the operating procedure chapter.
3. Non-condensable purge
If your machine is not equipped with an automatic air purge, you will find a manual air purge valve at the
equipment side, (with reference to chapter “Component identification”). Please refer to Pressure-temperature
chart and tank pressure, turn the valve purge the non-condensable till proper pressure is obtained in the tank.

Operating procedure
Recovery function
For the HFO-1234yf system, refrigerant identification is necessarily processed. Only when the purity of
refrigerant is above 98% the recovery is allowed.
Check and empty the used oil vessel before the recovery process is initiated.
The recovery process removes refrigerant from the vehicle A/C system, until a vacuum is reached. During this
process, the refrigerant is purified from any moisture, oil, and foreign particles. The processed refrigerant is then
stored in the internal storage cylinder of the machine, ready for re-use. If any oil is recovered during this process,
the oil will be discharged into the used oil vessel. After the first recovery has been completed, the machine will
pause for 3 minutes, to check if there is any refrigerant left in the vehicle A/C system. Recovery will start again
automatically if there is a pressure rise during the 3-minute pause. At the completion of recovery, the machine will
display and print the total amount of refrigerant recovered and oil if any.
Evacuation function
Select “Vacuum” , evacuation is performed to further remove air and moisture from the vehicle A/C system,
making it ready for oil injection. Evacuation time can be set from 2 to 60 minutes. If the machine has vacuum leak
test function, vacuum test can be selected to effect 10-minute vacuum leak test.
Oil injection function
Select “Oil injection”, set oil volume and new oil is sucked into A/C system by vacuum created by vacuum
function.
UV can be also selected to inject UV dye for future leak detection.
If the vehicle A/C system is not in a vacuum state, oil or dye injection cannot be performed and the machine will
display a warning.
Hose flush, if hose flush is selected (highly recommended), the process will flush the oil from the wall of the
service hoses and internal pipelines, to make sure the new oil to be injected is not contaminated with the previous
oil injected. This process will take about 5 minutes.

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).

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.

increase/decrease empty container weight, can correspondingly decrease/increase refrigerant/oil value displayed
in the main operation interface.
Component test:
The technician can activate and deactivate different electrical components of the machine. This is for quick and
easy diagnosis and troubleshooting.
Please note:
Only qualified technician (with special password) is allowed to access this function, not performing this test
correctly could cause damage to the machine or injury to the operator.

Caring for your equipment
●Keep your equipment clean and well maintained at all times.
●Keep service hoses stored on the storage adapters when not in use, to avoid dirt and dust
contaminating the internals of the couplers which will then end-up in the vehicle A/C system, which
can cause serious system malfunction.
●Always clean vehicle A/C system service ports before connecting machine quick couplers on to
the service ports.
●Keep the system stored in a clean area and away from direct sunlight and artificial heat source,
when not in use.
●Perform regular services on the system as recommended by the manufacturer. Ignoring and
skipping services will deteriorate the integrity of the machine.
●If the machine is used on badly contaminated A/C systems frequently, it is recommended that
more frequent vacuum pump oil changes are made, and main filter replacements are performed.
Contaminated vacuum pump oil will cause the internal corrosion of the vacuum pump, which
eventually will cause the failure of the vacuum pump. A contaminated main filter will decrease the
refrigerant purity.
●Do not bump or move the machine when the technician is in the process of charging a vehicle,
this can affect the charging accuracy.
●If the machine is bumped or knocked down accidentally, make calibration again and check for
possible leaking.
●DO NOT use compressed air to test for leaks.
●If the technician is not sure about the correct way of operating the machine, please do not
hesitate to contact your distributor or manufacturer. We always like to help you.
