HEATER AND EVAPORATOR UNIT SPECIFICATION

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 that the 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 the 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: When removing refrigerant components from a vehicle, cap immediately the components to prevent from the entry of moisture. When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the components. Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking on moisture. Use the recommended lubricant from a sealed container only.
  7. If an accidental discharge in the system occurs, ventilate the work area before resuming 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.

GUIDE PIN SPECIFICATION

Note. T means tensile intensity, which is stamped on the head of bolt only numeral.

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 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.

CAUTIONAir 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 resuming 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.

CAUTIONAir 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 resuming 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 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 (Refer to «LEAK TEST»(ref-286583-S18205409912008060300000) ).
  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.

CAUTIONAir 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 resuming 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 19.4 ± 0.88 oz. (550 ± 25g) of R-134a refrigerant. Do not overcharge the system the compressor will be damaged.

HANDLING OF OIL

  1. The oil should be free from moisture, dust, metal powder, etc.
  2. Do not mix with other oil.
  3. The water content in the oil increases when exposed to the air. After use, seal oil from air immediately. (HFC-134a Compressor Oil absorbs moisture very easily.)
  4. The compressor oil must be stored in steel containers, not in plastic containers.

COMPRESSOR OIL CHECK

The oil used to lubricate the compressor is circulating with the refrigerant.

Whenever replacing any component of the system or a large amount of gas leakage occurs, add oil to maintain the original amount of oil.

Oil total volume in system: PAG 150cc (5.07 fl.oz)
