Hyundai Creta: Air Conditioning System / Repair procedures
Refrigerant System Service
Basics |
Refrigerant Recovery
Use only service equipment that is U.L-listed and is certified to meet the requirements
of SAE J2210 to remove HFC-134a (R-134a) from the air conditioning system.
• |
Air conditioning refrigerant or lubricant vapor can irritate
your eyes, nose, or throat.
|
• |
Be careful when connecting service equipment.
|
• |
Do not breathe refrigerant or vapor.
|
|
If accidental system discharge occurs, ventilate the work area before resuming
of service.
Additional health and safety information may be obtained from the refrigerant
and lubricant manufacturers.
1. |
Connect a R-134a refrigerant
Recovery / Recycling / Charging system to the high-pressure service
port (A) and the low-pressure service port (B) as shown, following the
equipment manufacturer's instructions.
|
2. |
Measure the amount of refrigerant oil removed from the A/C system after
the recovery process is completed. Be sure to install the same amount
of new refrigerant oil back into the A/C system before charging.
|
System Evacuation
Use only service equipment that is U.L-listed and is certified to meet the requirements
of SAE J2210 to remove HFC-134a (R-134a) from the air conditioning system.
• |
Air conditioning refrigerant or lubricant vapor can irritate
your eyes, nose, or throat.
|
• |
Be careful when connecting service equipment.
|
• |
Do not breathe refrigerant or vapor.
|
|
If accidental system discharge occurs, ventilate the work area before resume
of service.
Additional health and safety information may be obtained from the refrigerant
and lubricant manufacturers.
1. |
When an A/C system has been open to the atmosphere, such as during installation
or repair, it must be evacuated using a R-134a refrigerant Recovery
/ Recycling / Charging system. (If the system has been open for several
days, the receiver/drier should be replaced, and the system should be
evacuated for several hours.)
|
2. |
Connect a R-134a refrigerant Recovery / Recycling / Charging system
(A) to the high-pressure service port (C) and the low-pressure service
port (B) as shown, following the equipment manufacturer's instructions.
|
3. |
If the low-pressure does not reach more than 93.3 kPa (700 mmHg, 27.6
in.Hg) in 10 minutes, there is probably a leak in the system. Partially
charge the system, and check for leaks (see Refrigerant Leak Test.)
|
4. |
Remove the low pressure valve from the low-pressure service port.
|
System Charging
Use only service equipment that is U.L-listed and is certified to meet the requirements
of SAE J2210 to remove HFC-134a (R-134a) from the air conditioning system.
• |
Air conditioning refrigerant or lubricant vapor can irritate
your eyes, nose, or throat.
|
• |
Be careful when connecting service equipment.
|
• |
Do not breathe refrigerant or vapor.
|
|
If accidental system discharge occurs, ventilate the work area before resuming
the service.
Additional health and safety information may be obtained from the refrigerant
and lubricant manufacturers.
1. |
Connect a R-134a refrigerant
Recovery / Recycling / Charging system (A) to the high-pressure service
port (C) as shown, following the equipment manufacturer's instructions.
|
2. |
Add to the system the same amount of new refrigerant oil as the one
removed during recovery. Use only specified refrigerant oil. Charge
the system with R-134a refrigerant. Do not overcharge the system to
prevent the compressor from damage.
Capacity : 530 ± 25g (18.7 ± 0.88oz.)

Refrigerant Leak Test
Always conduct a leak test with an electronic leak detector whenever leakage
or refrigerant is suspected and when conducting service operations which are
accompanied by disassembly or loosening or connection fittings.
In order to use the leak detector properly, read the manual supplied
by the manufacturer.
|
If a gas leak is detected, proceed as follows:
1. |
Check the torque on the connection fittings and, if too loose, tighten
to the proper torque. Check for gas leakage with a leak detector (A).
|
2. |
If leakage continues even after the fitting has been tightened, discharge
the refrigerant from the system, disconnect the fittings, and check
their seating faces for damage. Always replace, even if the damage is
slight.
|
3. |
Check the compressor oil and add oil if required.
|
4. |
Charge the system and recheck for gas leaks. If no leaks are found,
evacuate and charge the system again.
