Information and Caution

Instructions

When Handling Refrigerant

1. R-134a liquid refrigerant is highly volatile. A drop on the skin of your hand could result in localized frostbite. When

handling the refrigerant, be sure to wear gloves.

2. It is standard practice to wear goggles or glasses to protect your eyes, and gloves to protect your hands. If the

refrigerant splashes into your eyes, wash them with clean water immediately.

3. The R-134a container is highly pressurized. Never leave it in a hot place, and check storage temperature is below 52°C

(126°F).

4. An electronic leak detector should be used to check the system for refrigerant leakage. Bear in mind that the R-134a,

upon coming into contact with flame, produces phosgene, a highly toxic gas.

5. Use only recommended lubricant for R-134a systems. If lubricants other than the recommended one used, system

failure may occur.

6. PAG lubricant absorbs moisture from the atmosphere at a rapid rate, therefore the following precautions must be

observed:

A. When removing refrigerant components from a vehicle, cap the components immediately to prevent entry of

moisture.

B. When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the

components.

C. Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking on

moisture.

https://www.hyundaitechinfo.com/viewer/toc_print.asp?vehicletype=Pas...

3 of 57 3/12/2012 8:27 PM

D. Use the recommended lubricant from a sealed container only.

7. If an accidental discharge in the system occurs, ventilate the work area before resume of service.

When replacing parts ON A/C system

1. Never open or loosen a connection before discharging the system.

2. Seal the open fittings of components with a cap or plug immediately to prevent intrusion of moisture or dust.

3. Do not remove the sealing caps from a Replacement component until it is ready to be installed.

4. Before connecting an open fitting, always install a new sealing ring. Coat the fitting and seal with refrigerant oil before

making the connection.

When Installing Connecting Parts

Flange With Guide Pin

Check the new O-ring for damage (use only the specified) and lubricate by using compressor oil. Tighten the nut to

specified torque.

Handling tubing and fittings

The internal parts of the refrigeration system will remain in a state of chemical stability as long as pure moisture-free

refrigerant and refrigerant oil are used. Abnormal amounts of dirt, moisture or air can upset the chemical stability and

cause problems or serious damage.

The Following precautions must be observed

1. When it is necessary to open the refrigeration system, have everything you will need to service the system ready so the

system will not be left open any longer than necessary.

2. Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of dirt and moisture.

3. All lines and components in parts stock should be capped or sealed until they are ready to be used.

4. Never attempt to rebind formed lines to fit. Use the correct line for the installation you are servicing.

5. All tools, including the refrigerant dispensing manifold, the gauge set manifold and test hoses, should be kept clean

and dry.

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.

https://www.hyundaitechinfo.com/viewer/toc_print.asp?vehicletype=Pas...

6 of 57 3/12/2012 8:27 PM

- 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-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 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 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 opened to the atmosphere, such as during installation or repair, it must be evacuated

using an R-134a refrigerant Recovery/Recycling/Charging System. (If the system has been open for several days, the

receiver/dryer should be replaced, and the system should be evacuated for several hours.)

2. Connect an R-134a refrigerant Recovery/Recycling/Charging System (A) to the high-pressure service port (B) and the

https://www.hyundaitechinfo.com/viewer/toc_print.asp?vehicletype=Pas...

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 leak

in the system. Partially charge the system, and check for leaks (see 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 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) as shown, following the equipment

manufacturer's instructions.

2. Add the same amount of new refrigerant oil to system that was removed during recovery. Use only specified refrigerant

oil. Charge the system with 14.8 ± 0.88 oz. (420 ± 25g) of R-134a refrigerant. Do not overcharge the system the

compressor will be damaged.

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.

https://www.hyundaitechinfo.com/viewer/toc_print.asp?vehicletype=Pas...

8 of 57 3/12/2012 8:27 PM

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.
