FILLING COOLANT IN THE AIR CONDITIONING SYSTEM
Coolant: R134a
Re lling equipment: Re lling station
Quantity of uid: 1200 gr ± 50 gr
PAG ISO 100 SP20 Oil: No oil must be added. Just check to make sure there are 135ml of
oil in the compressor.
FILLING METHOD
Before using a lling station, consult the relevant user handbook for the device.
Filling liquid in the circuit for the rst time (duration 56 minutes)
1 - Connection of station to circuit (about 1 minute).
2 - Generation of vacuum in uid circuit (minimum 45 minutes).
• Reach vacuum pressure - 0.75 bar in 10 minutes at the most,
• Maintain the vacuum pressure - 0.99 bar max dehumidi cation for at least 30 minutes,
• Checking for leaks, at least 5 minutes.
3 - Filling operation (maximum 10 minutes).
Filling liquid after an operation (duration 90 minutes)
1 - Preparation (approx. 15 minutes).
• Connect the station to the circuit.
• Run the engine at 800 to 1200rpm.
• At the same time start up the air conditioner at maximum speed.
• Switch the vehicle o after 10 or 15 minutes.
2 - Recovery (approx. 15 minutes).
Has the purpose of recovering and recycling gas, oil and impurities present in the circuit.
Carry out the uid recovery cycle from the station.
3 - Wait for 3 to 4 minutes to allow recovery of micro-freezers of oil and moisture.
4 - Bleed the recovered oil (about 1 minute).
5 - Steps 1, 2 and 3 can be repeated if pressure formation is noticed during steps 2 and 3.
6 - Generation of vacuum in uid circuit (minimum 45 minutes).
• Reach vacuum pressure - -0.75 bar in 10 minutes or less,
• Maintain the vacuum pressure - 0.99 bar max dehumidi cation for at least 30 minutes,
• Checking for leaks, at least 5 minutes.
7 - Filling operation (maximum 10 minutes).
