Kia Sportage: Body / Air Conditioner Refrigerant/Compressor Repair procedures
Refrigerant System Service
Basics (R-134a) |
Refrigerant Recovery
Use only U.L.-listed service equipment that is certified to meet the requirements
of SAE J2210 when removing 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 in refrigerant or vapor.
|
|
If accidental system discharge occurs, ventilate work area before resuming to
service.
Additional health and safety information may be obtained from the refrigerant
and lubricant manufacturers.
1. |
Connect an R-134a refrigerant Recovery/Recycling/Charging System (A)
to the high-pressure service port (B) and the low-pressure service port
(C) 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 U.L.-listed service equipment that is certified to meet the requirements
of SAE J2210 when removing 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 in refrigerant or vapor.
|
|
If accidental system discharge occurs, ventilate work area before resuming to
service.
Additional health and safety information may be obtained from the refrigerant
and lubricant manufacturers.
1. |
When an A/C system has been opened 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 (B) and the low-pressure service port
(C) 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 leakage in the system. Partially
charge the system, and check for leakage. (See Refrigerant Leak Test.)
|
4. |
Remove the low pressure valve from the low-pressure service port.
|
System Charging
Use only U.L.-listed service equipment that is certified to meet the requirements
of SAE J2210 when removing 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 in 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. |
Connect an R-134a refrigerant Recovery/Recycling/Charging System (A)
to the high-pressure service port (B) and the low-pressure service port
(C) as shown, following the equipment manufacturer's instructions.
|
2. |
Add the same amount of new refrigerant oil to the system that was removed
during recovery. Use only specified refrigerant oil. Charge the system
with R-134a or R-1234yf refrigerant. Do not overcharge the system as
it may damage the compressor.
Specified amount
600 ± 25g (21.2 ± 0.8 oz.)
|
|
Refrigerant Leak Test
Always conduct a leak test with an electronic leak detector whenever leakage
of refrigerant is suspected and when conducting service operations that accompany
disassembling, loosening or connecting of 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 tightening torque of the connection fittings, and if it is
too loose, tighten to the proper torque. Using a leak detector (A),
check for gas leakage.
|
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. Replace at all times even for a slight
damage.
|
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.
|
Refrigerant System Service
Basics (R-1234yf) |
Refrigerant Identification
• |
Do not mix HFO-1234yf (R-1234yf) in the vehicle with other refrigerant,
such as R-12, R-134a and etc.
|
• |
Use only service equipment that is U.L-listed and is certified to meet
the requirements of SAE standards to recover and recycle R-1234yf from
the air conditioning system. Do not use service equipment for the other
refrigerant, such as R-12, R-134a and etc.
|
• |
Verify what refrigerant is in the system if there is concern that the
system has been tampered with in any way and check the type and quantity
of refrigerant that shall be in the A/C system and potential issues
arising from accidental or intentional mixing of refrigerants.
|
• |
Using an SAE certified refrigerant identification device is recommended
to prevent improper recovery and the resulting further spread of contaminated
refrigerant, which could potentially damage other A/C systems and service
equipment. Contaminated refrigerant (blend of more than one refrigerant
or non-system refrigerant) in recovery/recycling equipment could lead
to the potential contamination of more refrigerant.
|
• |
Certain types of electronic leak detection devices (heated diode or
corona discharge) as well as motors, switches, and controls on recovery
and recycling machines, could generate sparks that could serve as ignition
sources in the presence of refrigerants classified as flammable (A2
or A3) by ASHRAE standard 34 2006.
|
• |
It is possible that the mixing of refrigerants in a A/C system can result
in higher-than-expected system pressures, system and component damage,
diagnostic errors and/or other potential hazards to people and environment.
|
• |
In case other refrigerant is mixed, recover the contaminated refrigerant
in the A/C system and dispose it in accordance with all applicable national,
regional or local regulations. Clean inside the A/C system using the
specialized detergent and recharge new refrigerant.
|
Refrigerant Recovery
Use only service equipment that is U.L-listed and is certified to meet the requirements
of SAE standards to remove HFO-1234yf (R-1234yf) 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 work area before resume of
service.
Additional health and safety information may be obtained from the refrigerant
and lubricant manufacturers.
1. |
Connect an R-1234yf refrigerant Recovery/Recycling/Charging System (A)
to the high-pressure service port (B) and the low-pressure service port
(C) 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.
